What is the alkaline diet and why it is pseudoscience

The alkaline diet has been touted by various celebrities as a way to get healthy and prevent disease, but there is no scientific evidence to back these claims.

  • Though the diet promotes eating food that has an "alkalizing effect" on the body, the food you eat has no influence on your blood pH level.
  • Cutting out as many food groups as the diet recommends can lead to nutritional deficiencies, which could have an adverse effect on your health.
  • This article was reviewed by Samantha Cassetty, MS, RD, nutrition and wellness expert with a private practice based in New York City.
  • Visit Insider's homepage for more stories.
The alkaline diet has become a trend among celebrities like Gwyneth Paltrow and Jennifer Aniston as a way to lose weight, boost energy, and prevent disease.
But like most things that sound too good to be true, the alkaline diet is a prime example. Experts say there is no scientific evidence behind the idea that alkaline foods are healthier than acidic ones.
"It is not based on anything besides anecdotal evidence at this time," says Tracy Lockwood Beckerman, a registered dietitian in New York City.
The alkaline diet is pseudoscience

The idea behind the alkaline diet is that the foods you eat can change your blood pH level and thus change your health.
All you have to do is avoid foods that the diet categorizes as acidic, limit neutral foods, and focus on more alkaline foods. The alkaline diet categorizes foods according to pH as follows:
  • Acidic: Meat, fish, dairy, eggs, grains, alcohol
  • Neutral: Natural fats, starches, sugars
  • Alkaline: Fruits, nuts, legumes, vegetables
And while the foods you eat can affect the pH of your urine, this is not the same as changing your blood pH. Your blood pH level stays close to neutral at around 7.4, and you cannot shift your overall blood pH through your diet, as the alkaline diet suggests, says Beckerman.
"That's because our body is sharp and has built-in mechanisms to keep pH levels in check."
Moreover, alkaline diet proponents say that acidic foods leave behind an "acid ash" in the body, which may promote diseases like osteoporosis. Since then, several studies have shown that this assumption is not true.
The alkaline diet makes dangerous claims about cancer

In 2013, Victoria Beckham tweeted a picture of an alkaline cookbook, setting off a widespread diet trend that ended up influencing scores of celebrities including Kate Hudson, Gweneth Paltrow, and Tom Brady.
The founder of the alkaline diet, Robert Young, made the false claim that the diet aids in cancer treatment. As a result, some cancer patients have turned to the alkaline diet for treatment and found no relief.
In some cases, a strict alkaline diet only caused muscle-loss and back pain. Young was later sued and arrested for practicing medicine without a license.
Moreover, the American Institute for Cancer Research also rejects claims that eating acidic foods can lower the body's pH and promote cancer.
Just about the only health condition that an alkaline diet might help is kidney stones. Throughout the 20th century, researchers conducted numerous studies on pH levels in food and their effect on the kidneys. They discovered that eating more alkaline foods can help prevent kidney stones.
The alkaline diet can lead to nutritional deficiencies

Any time you cut food groups out of your diet, you need to be cautious, Beckerman says. "It could be setting you up for nutritional deficiencies if you don't prioritize your food choices."
For example, the alkaline diet cuts out some healthy food options such as eggs and fish while encouraging followers to adhere to strict diet rules. Without careful planning, an alkaline diet can cause muscle loss from a lack of protein and improper nutrition overall.
However, there is anecdotal evidence that the diet has helped people lose weight, stay healthy, and feel better. But this has nothing to do with consuming alkaline foods and everything to do with switching to the plant-based and whole-food options that the diet promotes.
If healthy, plant-based eating is your goal, there are other diets out there with the science to back their health benefits, like vegetarianism or veganism.

Top anti-inflammatory foods and supplements

With any chronic disease, including heart disease, malignancy or obesity, this condition is usually a key underlying factor, and if you don't deal with it, you may not improve. By choosing your foods and supplements carefully, you can make a signifi...


STORY AT-A-GLANCE

  • Chronic inflammation is a hallmark of virtually all disease, including cancer, obesity and heart disease. Your diet plays a significant if not primary role as it can either trigger or prevent inflammation
  • Leafy greens, berries and mushrooms are potent anti-inflammatory foods. People with autoimmune diseases may want to limit vegetables high in lectins, though, as they may cause more problems than they solve
  • Traditionally fermented and cultured foods are anti-inflammatory staples that work their “magic” by optimizing your gut flora. Examples include kefir, yogurt, natto, kimchee, miso, tempeh, pickles, sauerkraut, olives and other fermented vegetables
  • Marine-based omega-3 fats found in fatty cold-water fish that are low in environmental toxins are important anti-inflammatories that are particularly crucial for brain and heart health
  • Other anti-inflammatory foods and supplements include green tea, spices such as cloves, ginger, rosemary and turmeric, herbal remedies such as white willow bark, maritime pine bark and Cat’s claw, and supplements such as resveratrol, curcumin, capsaicin, vitamin D, zinc and SAM-e

anti inflammatory foods

Chronic inflammation is a hallmark of virtually all disease, including cancer, obesity and heart disease. While inflammation is a perfectly normal and beneficial process that occurs when your body's white blood cells and chemicals protect you from foreign invaders like bacteria and viruses, it leads to trouble when the inflammatory response gets out of hand and continues indefinitely.
Your diet plays a significant if not primary role in this chain of events and is the perfect place to start to address it. Certain nutritional supplements can also be helpful as add-ons.
Below, I’ll review some of the foods, spices and supplements known for their anti-inflammatory power (and the foods known for their inflammatory effects). If you struggle with any chronic health condition, chances are you have inflammation in your body, and would be wise to take a cold hard look at what you’re putting into it.

Anti-inflammatory food basics

A key part of an anti-inflammatory diet involves excluding refined vegetable oils, as they are clearly one of the most pernicious and pervasive poisons in the food supply. Simply avoiding all processed foods and most restaurant foods will go a long way toward helping you avoid them.
As for anti-inflammatory foods to eat more of, vegetables are a key staple. Dark leafy greens such as kale, collard greens and Swiss chard contain powerful antioxidants, flavonoids, carotenoids and vitamin C that can help protect against cellular damage. Ideally, opt for organic locally grown veggies that are in season, and consider eating a fair amount of them raw.
Juicing is an excellent way to get more greens into your diet. There’s a caveat, though. If you struggle with autoimmune disease or have significant inflammation in your body, consider limiting vegetables with high lectin content, as the lectins may pose a problem.
Among the most problematic lectin-containing foods are beans, grains, legumes and members of the nightshade family like eggplants, potatoes and peppers. High-lectin foods can be made safer to eat through proper soaking and cooking, as well as fermenting and sprouting. Using a pressure cooker is particularly beneficial for beans. You can learn more about this in my interview with Dr. Steven Gundry, author of “The Plant Paradox.”
Oxalates are another plant component that can cause problems, as they not only will increase inflammation but will worsen your mitochondrial function. Those prone to oxalate kidney stones typically need to be on an oxalate-free diet as well. Foods high in oxalates include potatoes (white and sweet), almonds, seeds, dark chocolatebeets, beans and many others.
On the other hand, raw berries — especially blueberries — are an anti-inflammatory basic, as most tend to be low in fructose while rating high in antioxidant capacity compared to other fruits and vegetables.
The same goes for mushrooms, which are commonly overlooked. Shiitake mushrooms, for example, contain ergothioniene, which inhibits oxidative stress. Mushrooms also contain a number of unique nutrients that you may not get enough of in your diet.
One of those nutrients is copper, which is one of the few metallic elements accompanied by amino and fatty acids that are essential to human health. Since your body can't synthesize copper, your diet must supply it regularly. Copper deficiency can be a factor in the development of coronary heart disease.
Another excellent anti-inflammatory mushroom is the Reishi, which contains ganoderic acid, a terpene that induces apoptosis (programmed cell death of damaged cells) and enhances the immune system.

Fermented and cultured foods

Traditionally fermented and cultured foods are other anti-inflammatory staples that work their “magic” by optimizing your gut flora. A majority of inflammatory diseases start in your gut as the result of an imbalanced microbiome.
Fermented foods such as kefir, natto, kimchee, miso, tempeh, pickles, sauerkraut, olives and other fermented vegetables will help reseed your gut with beneficial bacteria. Ideally, you’ll want to eat a wide variety of them as each contains a different set of beneficial bacteria (probiotics).
Fermented foods can also help your body rid itself of harmful toxins. Kimchi, for example, has been shown to break down pesticides that promote inflammation. As reported in a study1 in the Journal of Agricultural Food Chemistry, the organophosphate insecticide chlorpyrifos degraded rapidly during kimchi fermentation and was 83.3% degraded by Day 3. By Day 9, it was degraded completely.
If you don’t like fermented vegetables, consider yogurt made from raw organic milk from grass fed cows. Yogurt has been shown to reduce inflammation by improving the integrity of your intestinal lining, thereby preventing toxins in your gut from crossing into your bloodstream.

Other potent anti-inflammatory foods

Marine-based omega-3 fats found in fatty cold-water fish that are low in environmental toxins — such as wild Alaskan salmonsardines and anchovies — are also important anti-inflammatories2 and are particularly important for brain and heart health. In fact, your omega-3 level is a powerful predictor of mortality.
If you don’t enjoy these types of fish, you could consider using krill oil instead. Research published in the Scandinavian Journal of Gastroenterology3 in 2012 confirmed that dietary supplementation with krill oil effectively reduced inflammation and oxidative stress.
As with vitamin D, it’s advisable to check your omega-3 index on a regular basis to ensure optimization. Ideally, you’ll want to maintain an omega-3 index of 8%. (GrassrootsHealth offers a convenient, cost-effective test4 to measure both your vitamin D and omega-3 levels.)
Many teas also offer anti-inflammatory benefits that can be enjoyed by most. Matcha tea is the most nutrient-rich green tea5 and comes in the form of a stone-ground unfermented powder. The best Matcha comes from Japan.
It’s an excellent source of antioxidants, especially epigallocatechin gallate6 (EGCG), a catechin with anti-inflammatory activity.7 Tulsi is another tea loaded with anti-inflammatory antioxidants and other micronutrients that help protect against damage caused by chemical pollutants, heavy metals and physical stress.8

Anti-inflammatory herbs and spices

Ounce for ounce, herbs and spices are among the most potent anti-inflammatory ingredients available and making sure you’re eating a wide variety of them on a regular basis can go a long way toward preventing chronic illness.
According to a novel study9 in the Journal of the American College of Nutrition, published in 2012, “cloves, ginger, rosemary and turmeric were able to significantly reduce oxidized LDL-induced expression of TNF-α” or tumor necrosis factor, a cytokine involved in systemic inflammation.
Ginger lowered three different inflammatory biomarkers, suggesting its superior anti-inflammatory action, but rosemary and turmeric also “showed protective capacity by both oxidative protection and inflammation measures.”
The interesting thing about this study is that they used “real world” dosages, meaning amounts you would normally use in your daily cooking, not megadoses you might find in a concentrated supplement. For example, those in the oregano group ate just half a teaspoon of oregano daily for seven days.
Garlic is another kitchen staple that has been treasured for its medicinal properties for centuries. Garlic exerts its benefits on multiple levels, offering antibacterial, antiviral, antifungal and antioxidant properties. Most recently, a 2019 review and meta-analysis10 concluded garlic effectively lowered several inflammatory biomarkers, including C-reactive protein, TNF-α and interleukin-6.
It's thought that much of garlic's therapeutic effect comes from its sulfur-containing compounds, such as allicin. Research11 has revealed that as allicin digests in your body it produces sulfenic acid, a compound that reacts faster with dangerous free radicals than any other known compound.
An earlier study published in the Journal of Medicinal Foods12 found a direct correlation between the antioxidant phenol content of spice and herb extracts and their ability to inhibit glycation and block the formation of AGE compounds (advanced glycation end products), making them potent preventers of heart disease and premature aging.
Here, cloves were ranked as the most potent of 24 common herbs and spices found in your spice rack. The following were found to be the top 10 most potent anti-inflammatory herbs and spices:
Cloves
Cinnamon
Jamaican allspice
Apple pie spice mixture
Oregano
Pumpkin pie spice mixture
Marjoram
Sage
Thyme
Gourmet Italian spice

Curcumin — A powerful anti-inflammatory with poor absorption

Curcumin, the active ingredient in turmeric, also has a solid foundation in science with numerous studies vouching for its anti-inflammatory effects.13 As noted in a 2017 review in the journal Foods:14
“[Curcumin] aids in the management of oxidative and inflammatory conditions, metabolic syndrome, arthritis, anxiety, and hyperlipidemia. It may also help in the management of exercise-induced inflammation and muscle soreness, thus enhancing recovery and performance in active people.
In addition, a relatively low dose of the complex can provide health benefits for people that do not have diagnosed health conditions. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects.”
A drawback of turmeric is its poor absorbability and rapid elimination. As noted in this Foods review, taken by itself turmeric typically does not impart the health benefits with which this spice is associated.
Certain components or additives can significantly boost its bioavailability though. One is piperine, the active ingredient in black pepper, which has been shown to increase the bioavailiability of curcumin by 2,000%.15 This is why you’ll typically find piperine as an ingredient in most curcumin supplements. A typical dosage of a standardized curcumin supplement is 400 to 600 milligrams three times a day.16

Anti-inflammatory ingredients can provide natural pain relief

Another interesting paper in the journal Surgical Neurology International, “Natural Anti-Inflammatory Agents for Pain Relief,” highlights several foods and spices already mentioned, specifically omega-3, green tea and turmeric. In addition to those, it also discusses the anti-inflammatory potential of:17
  • White willow bark
  • Maritime pine bark (pycnogenol)
  • Resveratrol
  • Cat’s claw (Uncaria tomentosa)
  • Chili pepper (capsaicin)
Interestingly, a 2013 animal study18 found capsaicin “produced anti-inflammatory effects that were comparable to diclofenac,” a nonsteroidal anti-inflammatory drug commonly prescribed to patients with mild to moderate arthritis.19

Frankincense

The Surgical Neurology International paper20 also addresses the use of Frankincense extract (Boswellia serrata resin), noting it “possesses anti-inflammatory, anti-arthritic, and analgesic properties” and is an inhibitor of leukotriene biosynthesis.
As such, it’s valuable in the treatment of inflammatory diseases driven by leukotrienes,21 such as degenerative and inflammatory joint disorders. According to this paper, Frankincense:
“… reduces the total white blood cell count in joint fluid, and it also inhibits leukocyte elastase, which is released in rheumatoid arthritis. In one recent study, a statistically significant improvement in arthritis of the knee was shown after 8 weeks of treatment with 333 mg B. serrata extract taken three times a day …
A combination of Boswellia and curcumin showed superior efficacy and tolerability compared with nonsteroidal diclofenac for treating active osteoarthritis. Boswellia typically is given as an extract standardized to contain 30-40% boswellic acids (300-500 mg two or three times/day).”
An earlier study22 published in Scientific Reports in 2015 confirmed Frankincense and myrrh are both capable of suppressing inflammation by inhibiting the expression of inflammatory cytokines.

The importance of vitamin D

Some anti-inflammatory supplements have already been mentioned, such as curcumin, Cat’s claw, Frankincense and capsaicin. Other supplements with well-documented anti-inflammatory effects include vitamin D, S-adenosylmethionine (SAM-e) and zinc. As reported by Science Daily, vitamin D inhibits inflammation by reducing inflammatory proteins:23
“… [R]esearchers examined the specific mechanisms by which vitamin D might act on immune and inflammatory pathways.24 They incubated human white blood cells with varying levels of vitamin D, then exposed them to lipopolysaccharide (LPS), a molecule associated with bacterial cell walls that is known to promote intense inflammatory responses.
Cells incubated with no vitamin D and in solution containing 15 ng/ml of vitamin D produced high levels of cytokines IL-6 and TNF-alpha, major actors in the inflammatory response. Cells incubated in 30 ng/ml vitamin D and above showed significantly reduced response to the LPS. The highest levels of inflammatory inhibition occurred at 50 ng/ml.
Through a complex series of experiments, the researchers identified a new location where the vitamin-D receptor appears to bind directly to DNA and activate a gene known as MKP-1. MKP-1 interferes with the inflammatory cascade triggered by LPS, which includes a molecule known as p38, and results in higher levels of IL-6 and TNF-alpha.
‘This newly identified DNA-binding site for the vitamin-D receptor, and the specific pathways inhibited by higher levels of vitamin D provide a plausible mechanism for many of the benefits that have been associated with vitamin D,’ said Dr. Goleva.
'The fact that we showed a dose-dependent and varying response to levels commonly found in humans also adds weight to the argument for vitamin D's role in immune and inflammatory conditions.’"
While I strongly recommend getting your vitamin D from sensible sun exposure, if you cannot maintain a protective level of 60 to 80 ng/ml year-round, a vitamin D3 supplement would be prudent, considering its importance for your overall health. 

Zinc and SAM-e

Zinc is a commonly overlooked antioxidant, but research shows it’s a potent anti-inflammatory. According to a 2014 review article25 in the journal Frontiers in Nutrition:
“Zinc supplementation trials in the elderly showed that the incidence of infections was decreased by approximately 66% in the zinc group. Zinc supplementation also decreased oxidative stress biomarkers and decreased inflammatory cytokines in the elderly.
In our studies in the experimental model of zinc deficiency in humans, we showed that zinc deficiency per se increased the generation of IL-1β and its mRNA in human mononuclear cells following LPS stimulation.
Zinc supplementation upregulated A20, a zinc transcription factor, which inhibited the activation of NF-κB, resulting in decreased generation of inflammatory cytokines.”
Similarly, SAM-e is commonly recommended for patients with osteoarthritis,26 as it has both anti-inflammatory and analgesic (pain relieving) properties. According to Arthritis.org,27 “Results may be felt in just one week but could take more than a month.”

Inflammatory foods to avoid

Last but not least, it's important to realize that dietary components can either trigger or prevent inflammation from taking root in your body, so avoiding inflammatory foods is just as important, if not more so, as eating anti-inflammatory ones.
As a group, processed foods of all kinds tend to be pro-inflammatory, thanks to ingredients like high fructose corn syrup, soy, processed vegetable oils (trans fats) and chemical additives. So, in addition to adding anti-inflammatory foods, herbs, spices and supplements (if needed) to your diet, you’ll also want to avoid the following as much as possible:
Refined sugar, processed fructose and grains — If your fasting insulin level is 3 or above, consider dramatically reducing or eliminating grains and sugars until you optimize your insulin level, as insulin resistance is a primary driver of chronic inflammation.
As a general guideline, I recommend restricting your total fructose intake to 25 grams per day. If you’re insulin or leptin resistant (have high blood pressure, high cholesterol, heart disease or are overweight), consider cutting that down to 15 grams per day until your insulin/leptin resistance has normalized
Oxidized cholesterol — Cholesterol that has gone rancid, such as that from overcooked, scrambled eggs
Processed meats
Industrial vegetable and seed oils (a source of oxidized omega-6 fats) such as peanut, corn and soy oil
Foods cooked at high temperatures, especially if cooked with vegetable oil
Replacing processed foods with whole, ideally organic foods will automatically address most of these factors, especially if you eat a large portion of your food raw. Equally important is making sure you’re regularly reseeding your gut with beneficial bacteria, as mentioned above.
To help you get started on a healthier diet, I suggest following my free Optimized Nutrition Plan, which starts at the beginner phase and systematically guides you step-by-step to the advanced level.

Does this viral photo of kidney stones really show the effect of too many energy drinks?

A graphic image of severe kidney stones has been circulating for years online, with a message about the dangers of consuming too many energy drinks. 

Claudia Tanner 8 months Thursday August 9th 2018

This image has been shared online hundreds of thousands of times – but experts warn it's message is somewhat misleading (Photo: Facebook/Jason Hallman)
This image has been shared online hundreds of thousands of times – but experts warn it’s message is somewhat misleading (Photo: Facebook/Jason Hallman)

One version of the photo, which has been shared hundreds of thousands of times on Facebook, claims that it “belonged to someone who overindulged in energy drinks” and tells other users, “Show this to folks that’s [sic] addicted”. 

But experts say that while guzzling gallons of the stuff isn’t advisable, the viral post doesn’t paint an entirely accurate picture. i spoke to one urologist who warned that he’s seen a rise in young people suffering with the condition which he blames on increased consumption of protein drinks.

What are kidney stones? 

Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They are quite common with around three in 20 men and up to two in 20 women developing them at some stage of their lives, according to the NHS. Stones can develop in one or both kidneys and most often affect people aged 30 to 60. 

Small kidney stones may go undetected and be passed out painlessly in the urine. But it’s fairly common for a stone to block part of the urinary system which can cause severe pain in the abdomen or groin and sometimes causes a urinary tract infection (UTI). 

Larger stones may need to be broken up using ultrasound or laser energy. Occasionally, keyhole surgery may be needed to remove very large kidney stones directly. 

Is there a link between kidney stones and energy drinks? 

Kidney stones are usually formed following a build-up of certain chemicals in the body, such as calcium, oxalate, uric acid and cysteine, according to the NHS. Most are calcium stones, usually in the form of calcium oxalate. Energy drinks and other caffeinated beverages like coffee, tea and soda contain oxalate, hence the belief that they can cause the problem. 

Spire consultant urologist Subu Subramonian confirmed that the case pictured did appear to be kidney stones. However, he said such a severe case is unlikely to be caused entirely by excessive consumption of energy drinks.

“The appearance suggests that the patient may have a congenital condition such as renal tubular acidosis which predispose them to multiple calcification in the meat and tubes of the kidney due to a fault in the filtration mechanism for calcium in the micro tubes of the kidney. This condition leads to recurrent and multiple stones in the kidney and patient may end up with some kidney dysfunction as well.” 

He explained that kidney stones often have no definite, single cause, and that several factors increase risk. “Other contributing factors in play here could be inadequate water intake (as in most patients with kidney stones) and high consumption of animal protein and salt,” he said. 

“Although energy drinks could be responsible for a number of health hazards such diabetes due to excessive sugar content, there is no direct evidence to link it with kidney stone disease. It has been shown that people with diabetes have more incidence of kidney stones and therefore there might be indirect link.” 

Therefore, drinking a lot of energy drinks isn’t a good idea for their sugar content, but this alone is very unlikely to cause kidney stones. “Kidney stones tend to be calcium based, but it usually has no relationship with consuming calcium through diet and supplements,” added Mr Subramonian. 

The risks of protein drinks 



A diet rich in animal protein, because of its high purine content, which produces uric acid as it metabolises, may increase the risk of uric acid stone formation, experts say. 

Mr Subramonian said: “As a stone specialist, I am more worried more about the recent trend in increased consumption of protein drinks amongst youngsters as I see a lot of these young people coming to my stone clinic with new onset kidney stones. This is a trend I am seeing more recently over the last 10 years as protein drinks are promoted by sports shops, advertisements and even some gym trainers. 

“My advice to the public is to drink at least two litres of water a day and eat a healthy balanced diet to prevent kidney stones.” 

5 steps for preventing kidney stones 

The following advice appears from an expert on a Harvard Health Blog: 

Drink plenty of water: Drinking extra water dilutes the substances in urine that lead to stones. Strive to drink enough fluids to pass 2 liters of urine a day, which is roughly eight standard 8-ounce cups. It may help to include some citrus beverages, like lemonade and orange juice. The citrate in these beverages helps block stone formation. 

Get the calcium you need: Getting too little calcium in your diet can cause oxalate levels to rise and cause kidney stones. To prevent this, take in the  amount of calcium appropriate to your age. Ideally, obtain calcium from foods, since some studies have linked taking calcium supplements to kidney stones. Men 50 and older should get 1,000 milligrams (mg) of calcium per day, along with 800 to 1,000 international units (IU) of vitamin D to help the body absorb the calcium. 

Reduce sodium: A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. So a low-sodium diet is recommended for the stone prone. Current guidelines suggest limiting total daily sodium intake to 2,300 mg. If sodium has contributed to kidney stones in the past, try to reduce your daily intake to 1,500 mg. 

Limit animal protein: Eating too much animal protein, such as red meat, poultry, eggs, and seafood, boosts the level of uric acid and could lead to kidney stones. A high-protein diet also reduces levels of citrate, the chemical in urine that helps prevent stones from forming. If you’re prone to stones, limit your daily meat intake to a quantity that is no bigger than a pack of playing cards. 

Avoid stone-forming foods: Beets, chocolate, spinach, rhubarb, tea, and most nuts are rich in oxalate, and colas are rich in phosphate, both of which can contribute to kidney stones. If you suffer from stones, your doctor may advise you to avoid these foods or to consume them in smaller amounts.

By Dr. Mercola
It's that time again — time to embrace a new year and a fresh start in our continued journey toward a healthier, happier life.  With a nod to our upcoming 20th anniversary in 2017, I've selected 20 tips from my 20 most popular articles of 2016.
If you haven't yet read them all, you're in for a treat, as they cover a wide variety of health topics.
Implementing some or all of these could help protect your health and well-being in the years to come. And be sure to stay tuned to the newsletter for more empowering health wisdom as 2017 unfolds.
The heading of each section is a hyperlink and if you click on it you will go to the article that has far more details.
We're now starting to realize that mitochondrial dysfunction is at the core of virtually all diseases, and support for nutritional ketosis is growing by leaps and bounds. 2016 was a breakthrough year for this kind of information.
For over 80 years, nutritional ketosis has been the standard of care for intractable seizures in children.
Now we're finding it can benefit a wide array of other diseases, including neurodegenerative diseases such as Alzheimer's and Parkinson's, obesity, diabetes, heart failure, heart disease, arthritis and more.       
One of the reasons it works so well is because it drives your inflammation down to very low levels. When inflammation disappears, your body can heal. It also takes the proverbial foot off the gas pedal of aging. My next book, "Fat for Fuel," scheduled for release in May, 2017, will explain it all in detail.
Without this information, people will continue to die prematurely. At present, the cancer industry is focusing on the downstream effects of the problem, which is why the "war on cancer" has been such a miserable failure.
When you view cancer as a metabolic disease, you can actually target and manage the disease without creating systemic toxicity. You do this primarily by targeting the fuels the cancer cells use (primarily glucose). 

Without the appropriate fuel, the cancer cells cannot grow and multiply. Five strategies that will help optimize your mitochondrial function include:
  1. Peak Fasting and other types of fasting
  2. Eating foods low in net carbs and protein and high in healthy fats
  3. Optimize your iron levels by getting ferritin to 60 ng/mL
  4. Exercise
  5. Reduce mitochondrial ROS production by avoiding food for at least three hours before bedtime
  6. Get sensible sun exposure, as a majority of the energy your body needs to maintain systemic equilibrium comes from environmental infrared light exposure, and avoid light-emitting diode (LED) lighting (see next section)
The importance of near-infrared light exposure to health and the adverse effects of LED lighting, as explained by Dr. Alexander Wunsch, a world class expert on photobiology, was another breakthrough health revelation of 2016.
LED lighting may actually be one of the most damaging, non-native EMF radiation exposures you have on a daily basis. You cannot feel near-infrared as heat, and you cannot see it, but it' has a major beneficial impact in terms of health.
Near-infrared frequencies are what is missing in non-thermal artificial light sources like LEDs and fluorescents. Importantly, it appears to promote age-related macular degeneration (AMD), which is the leading cause of blindness.
The primarily blue light emitted by LEDs also generates excessive amounts of reactive oxygen species (ROS), thereby exacerbating health problems rooted in mitochondrial dysfunction, which run the gamut from metabolic disorder to cancer. 
The healthiest indoor lighting includes clear incandescent light bulbs (a 2,700 K incandescent, thermal analog light source), low-voltage halogen lights operated on DC (not AC, which generates dirty electricity), and/or fragrance-free candles.
Be particularly mindful to only use incandescents at night. After sunset, consider it is best to put on a pair of  blue-blocking glasses.
One lifestyle factor that appears to be driving obesity and many chronic disease processes is the fact that we eat too frequently. When you eat throughout the day and never skip a meal, your body adapts to burning sugar as its primary fuel, which down regulates enzymes that utilize and burn stored fat.
Many biological repair and rejuvenation processes also take place when your body is not busy processing food. Mounting research suggests your body was designed to cycle through periods of feast and famine, and without periods of fasting, your health suffers.
Intermittent fasting, which mimics the eating habits of our ancestors, helps restore your body to a more natural state that allows a whole host of biochemical benefits to occur.
"Peak fasting" involves fasting for 13 to 18 hours each day and eating all of your meals within the remaining window of 6 to 11 hours. To make this schedule work, you need to skip either breakfast or dinner. However, if you chose to eat dinner, be sure to do so at least three hours before bedtime.
When sleeping, your body needs the least amount of energy. Eating at a time when energy is not needed ends up creating a situation in which your mitochondria create excessive amounts of damaging free radicals.
This is another important factor that can help optimize your mitochondrial function and limit cellular damage that drives aging and disease.
Iron overload is incredibly common and likely as dangerous to your health as vitamin D deficiency. Elevated iron creates excessive free radicals that damage your mitochondrial DNA, cell membranes and electron transport proteins.
If left untreated, it can damage your organs and contribute to cancer, heart disease, diabetes, neurodegenerative diseases and many other disorders.
The serum ferritin test measures your stored iron. I strongly recommend all adults to get this test done on an annual basis.
Ideally, your serum ferritin should be between 20 and 80 nanograms per milliliter (ng/mL); somewhere between 40 and 60 ng/mL is the sweet spot for adult men and non-menstruating women.
If your ferritin level is above 80 ng/mL, the solution is to donate your blood. If it's over 200 ng/mL, a more aggressive phlebotomy schedule is recommended.
The term autophagy means "self-eating," and refers to the processes by which your body cleans out various debris, including toxins, and recycles damaged cell components.
By boosting your body's autophagy process, you dampen inflammation, slow down the aging process, and optimize biological function. Here are four strategies to boost your body's autophagy process:
1.Exercise. The amount of exercise required to stimulate autophagy in humans is still unknown; however, it is believed that intense exercise is more effective than mild exercise.
Research shows the "Goldilocks zone" in which exercise produces the greatest benefit for longevity is between 150 to 450 minutes of moderate exercise per week, lowering your risk of early death by 31 and 39 percent respectively.
Spending at least 30 percent of your workout on high-intensity exercises further boosts longevity by about 13 percent, compared to exercising at a consistently moderate pace. Following these general guidelines will likely put you in the most advantageous position for maximizing autophagy.
2.Avoid excessive protein. One of the quickest ways to shut down autophagy is to eat large amounts of protein, as this stimulates mTOR, and IGF-1, both of which are potent inhibitors of autophagy.
To avoid this, limit your protein to 1 gram of protein for every kilogram of lean body mass, or one-half gram of protein per pound of lean body mass.
3.Fasting is another biological stressor that produces many beneficial results, including autophagy. In fact, some of the benefits associated with fasting — such as a reduced risk of diabetes and heart disease — can at least in part be attributed to this process.
4.Nutritional ketogenesis is a fourth strategy that will help boost autophagy, and to accomplish that, you need to cut down on the non-fiber carbs and increase the amount of healthy fat in your diet, along with a moderate amount of protein.
Nutritional ketosis is an effective way to improve your health, and can be used both for the prevention and treatment of chronic disease, including cancer and diseases rooted in toxicity. If your mitochondria are functioning well, they will efficiently metabolize fat. If they don't, it suggests you're primarily burning carbohydrates as a primary fuel.
Nutritional ketosis involves removing sugars and processed carbohydrates, replacing the lost calories with healthy fats and a moderate amount of high-quality protein. Doing so will shift your body into a metabolic state in which your body burns fat rather than glucose as its primary fuel.
As a general rule, you'll want at least 50 to 75 percent of your total calories (some may benefit from as much as 85 percent) from healthy fats, such as olives, avocados, coconut oil, MCT oil, organic pastured butter, cacao butter, raw nuts such as macadamia and pecans, seeds such as black sesame, cumin, pumpkin and hemp seeds, organic pastured eggs, grass-fed meats, lard and tallow.
A tool that will radically improve your ability to understand what you're eating and follow a ketogenic diet is a nutrient tracker. There are a number of them available, but the most accurate one is Cronometer.com/Mercola. That's our revision of the basic tracker, and it's already set up for nutritional ketosis.
The disastrous "low-fat diet" dogma of the last half century has led to a devastating drop in most people's intake of healthy saturated fats, including MCTs. Besides coconuts, coconut oil and palm kernel oil, small amounts of MCT can be found in butter and other high-fat dairy products from grass-fed cows and goats.
MCTs can be divided into four groups based on their carbon length, which ranges from six to 12 carbons.1 As a general rule, the shorter the carbon chain, the more efficiently the MCT will be turned into ketones, which are an excellent source of energy for your body — far preferable to glucose, as ketones produce far less ROS when they are metabolized to produce ATP.
My personal preference is straight caprylic acid (C8), as it converts to ketones far more rapidly than the more common C8 and C10 mixtures. Since MCT oil, and especially caprylic acid (C8) oil, is a far more concentrated source than coconut oil, it's often appropriate for clinical uses, which include:2
  • Appetite reduction and weight loss3,4
  • Improved cognitive and neurological function with possible implications in neurodegenerative diseases
  • Increased energy levels and improved athletic performance
  • Improved mitochondrial function and subsequent reduced risk for diseases such as atherosclerosis, diabetes, cancer, cardiovascular disease, autoimmune diseases and epilepsy5
  • Prevention of non-alcoholic fatty liver disease (NAFLD)6
The common belief is that if you want to build muscle, you need to eat lots of protein and carbohydrates because carbs fuel your muscles and protein builds them up. However, carb- and protein-loading can have significant drawbacks in terms of long-term health, and mounting evidence suggests you don't need either in excessive amounts to build muscle.
One particularly intriguing finding is that your body has a mechanism that allows it to build muscle even when deprived of food. Certain amino acids — most notably branched chain amino acids like leucine — signal muscle genes to grow and to build protein, and they do that even during times of food deprivation as long as these amino acids are circulating through your blood stream.
Including the following foods in your cooking as often as possible will provide you with leucine and other nutrients that play important roles in muscle building and maintenance. Just be careful to limit whey protein to days that you are strength training.
Wild-caught Alaskan salmon
Avocado
Spinach
Coconut oil
MCT oil
Kale
Sprouts
Berries
Bananas
Watermelon
Grapefruit
Papaya
Raw nuts
Grass-fed beef
Mushrooms
Whey protein
Broccoli
As a general rule, I recommend getting the bulk of your nutrition from eating real food. That said, in some cases, taking specific nutrients may be therapeutically valuable or necessary, and can be far less toxic and less expensive than drug treatments. Moreover, in my view there are certain supplements that most people will benefit from taking.
Vitamin D3 (unless you're able to get sufficient amounts of sun exposure year-round) is at the top of that list, along with vitamin K2. Animal-based omega-3 fat, such as the fat found in krill oil, is another nutrient that most people simply don't get enough of.
If you still have not shifted away from processed foods, vitamin C may be worth considering, as processed foods will not provide you much of this vitamin. If you're not eating traditionally fermented foods, you'd also be wise to take a high quality probiotic supplement, and at the very least consider increasing your consumption of fresh vegetables, as the fiber provides important nourishment for beneficial bacteria in your gut that help calibrate your immune system.
When selecting a high-quality dietary supplement, be sure it is as close as possible to its natural (whole food) form and follows industry standards for quality assurance including ISO 9001, ISO 17025, and Good Manufacturing Processes (GMP) certifications.
Kidney stones can be truly agonizing. Fortunately, there are ways to prevent them from ever occurring. Recent research shows that an extract of a compound called hydroxycitrate from the Asian garcinia cambogia fruit, also known as Malabar tamarind, has the power to inhibit the growth of kidney stones. It can even be used to dissolve them after a stone has been generated.
If all goes as hoped, hydroxycitrate would be the most dramatic advance in treating kidney stones in three decades. However, rigorous trials in humans have not yet begun, so it's still too early to justify its use. In the meantime, to prevent keep your kidneys healthy and prevent kidney stones:
  • Drink plenty of water to avoid dehydration
  • Limit your protein intake to one-half gram of protein per pound of lean body mass
  • Avoid foods high in oxalate, such as Swiss chard, beets, tea, sweet potatoes, rhubarb, chocolate, okra, almonds and spinach if you're at high risk for kidney stones
  • Make sure you're getting enough magnesium (especially if you avoid the high-oxalate foods above, which are also high in magnesium)
Magnesium is vitally important for biological function and optimal health. If you're lacking in cellular magnesium, it can lead to the deterioration of your cellular metabolic function, which in turn can snowball into more serious health problems. Importantly, magnesium is vital for the optimization of your mitochondria.
Eating plenty of organic unprocessed foods tend to be your best bet, but since most soils have become severely depleted of nutrients, some magnesium experts believe virtually everyone needs to take supplemental magnesium.
The recommended daily allowance (RDA) is around 310 to 420 milligrams (mg) per day depending on your age and sex, although some researchers believe we may need as much as 600 to 900 mg/day for optimal health. One way to identify your ideal dose is to use your intestinal reaction as a marker. Start out by taking 200 mg of oral magnesium citrate per day, and gradually increase your dose until you develop slightly loose stools.
When your body has too much magnesium it flushes it out, so in this way you can determine your own individual cutoff point. (Be sure to use magnesium citrate, as it's known for having a laxative effect.)
When it comes to magnesium supplements, my personal preference is magnesium threonate, as it seems to be most efficient at penetrating cell membranes, including your mitochondria, which can help boost your energy level. It also penetrates your blood-brain barrier and may help improve memory. 
Most vegetables are very low in net carbs while being high in healthy fiber and the valuable vitamins and minerals your body needs for optimal health. However, some are more beneficial than others. Among the top performers are:
  • Sprouts, especially watercress, broccoli sprouts and sunflower seeds
  • Cruciferous vegetables such as cauliflower and broccoli
  • Leafy greens such as kale, beet greens, arugula, spinach, Swiss chard and collard greens
  • Peppers, such as bell peppers, banana peppers, Poblano and chili peppers
  • Certain root vegetables, specifically ginger, turmeric and onions
As much as 40 percent of U.S. health care expenditures are for diseases directly related to the overconsumption of sugar.7One of the key mechanisms by which sugar promotes cancer and other chronic disease is by causing mitochondrial dysfunction. As mentioned earlier, sugar is not an ideal fuel as it creates far more ROS than fat. This generates free radicals, which in turn causes mitochondrial and nuclear DNA damage along with cell membrane and protein impairment.
I recommend reducing your total fructose intake to a maximum of 25 grams per day from all sources, including fruit. If you are insulin resistant, you'd do well to make your upper limit 15 grams per day. Cancer patients would likely be best served by even stricter limits. Moreover, I personally believe that most would benefit from reducing all non-fiber carbs (total carbs minus fiber), not just fructose, to less than 100 grams per day.
The easiest way to dramatically cut down on your sugar and fructose consumption is to switch to REAL foods, as most of the added sugar you end up with comes from processed foods. Other ways to cut down includes:
  • Cutting back on the amount of sugar you add to your food and drink
  • Using Stevia or Lo Han instead of sugar and/or artificial sweeteners. You can learn more about the best and worst of sugar substitutes in my previous article, "Sugar Substitutes — What's Safe and What's Not"
  • Using fresh fruit in lieu of canned fruit or sugar for meals or recipes calling for a bit of sweetness
  • Using spices instead of sugar to add flavor to your meal
Your hair color comes from pigment called melanin. With age, melanin is reduced, which is why your hair turns gray and, ultimately, white once there's no melanin left. In 2016, researchers discovered a gene that accounts for about 30 percent of hair graying. The other 70 percent is likely due to factors such as age, toxic exposures, nutritional deficiencies and stress. To limit the grays:
  • Avoid smoking
  • Minimize oxidative stress by avoiding pollution and stress
  • Eat a healthy antioxidant-rich diet
  • Increase your vitamin B12 intake
  • Normalize your weight
Mounting research confirms that many people experience adverse reactions to gluten even if they test negative for celiac disease — an autoimmune disorder in which gluten must be avoided at all cost. This suggests gluten-sensitivity is a real problem,8 and that gluten-free diets may benefit many, not just those with celiac.  In one recent study,9,10 people who reacted to gluten despite not having celiac disease were found to have leaky gut, which is likely what caused the immune activation.
The obvious treatment for celiac disease and gluten intolerance is a gluten-free diet, which means abstaining from any food that contains gluten.
This is largely because most is contaminated with Roundup used in the drying process, which tends to damage your intestinal cellular connections. However, keep in mind that while gluten-free has many advantages, just because a food is gluten-free does not automatically make it healthy. There are plenty of gluten-free junk foods out there, so be mindful of your choices.
If you have osteoarthritis — a degenerative form of arthritic joint disease — exercise is absolutely crucial to your well-being. The notion that exercise is detrimental to your joints is a misconception; there is no evidence to support this belief. Importantly, exercise can help reduce joint pain and make it easier for you to perform daily tasks.
That said, people with arthritis should be careful to avoid activities that aggravate joint pain, and any exercise that strains a significantly unstable joint. Aside from that, you can include a range of activities in your exercise program, just as any other exerciser would.
Weight training, high-intensity cardio, stretching and core work can all be integrated into your routine according to your ability. The featured article also includes a series of flexibility exercises that will help strengthen your hips, which are suitable for those with hip osteoarthritis.
This year's presidential election has unleashed an avalanche of anxiety and emotional distress, with more than 8 in 10 voters reporting feeling "repulsed" by the campaign.11 Sadly, many have fallen into victim mentality, forgetting that the power of the individual is still alive and well even in this deeply flawed system.
It becomes yours by stepping OUTSIDE of the system with every decision and purchase you make. With every action you take, you also set the example for others to follow, thereby making you a change-agent within your own small circle of family, friends and acquaintances. In the end, our collective actions will create the changes that are so desperately needed.
If you don't like the state of the nation (or the world), stop eating processed and ultra-processed junk foods. Some may initially think this decision would have nothing to do with anything that is wrong in the world, but if you really give it some thought, you'll realize that the more independence you gain with your food, the more independence you will create in other areas as well.
Workout intensity and workout volume are inversely proportional, so the greater the intensity, the less time you spend working out, and the less frequently you need to exercise. High intensity interval training (HIIT) can significantly reduce the amount of exercise you need to do, cutting your hour-long workouts down to 15 minutes once a week or less.
Moreover, as intensity goes up, you also need longer recovery times in between sessions, so the frequency of your workouts also goes down. At most, you might be able to do HIIT three times a week. You can perform HIIT using a recumbent bicycle, a treadmill, or by sprinting, for example.
Or you can use weights — a technique known as SuperSlow weight training. A sample workout routine is given in the featured article. In terms of health effects, HIIT may help improve a number of biomarkers associated with improved metabolic activity and good health, including:
  • Improved insulin sensitivity and reversal of type 2 diabetes
  • Normalized cholesterol, eliminating the need for statin drugs
  • Reversal of bone mineral loss and reversal of osteoporosis
  • Improved C-reactive protein levels (marker for inflammation)
Research clearly shows that proton pump inhibitors (PPIs) are severely overprescribed and misused, and do far more harm than good in the long run.12 If you suffer from frequent heartburn, there are many alternative treatment strategies that can help you eliminate this problem without the serious side effects associated with PPIs, which include kidney disease, pneumonia, osteoporosis, hip fractures, dementia, and an increased risk for heart disease13 and heart attacks.14
The long-term answer to heartburn and acid indigestion is to restore your natural gastric balance and function. The most important step is to eat real food, as processed foods and sugars are a surefire way to exacerbate acid reflux. Reseeding your gut with beneficial bacteria, either from traditionally fermented foods or a high quality probiotic supplement is also important. Other drug-free treatment strategies include the use of:  
Raw, unfiltered apple cider vinegar
Baking soda
Aloe Vera juice
Ginger root
Vitamin D
Astaxanthin
Slippery elm
Glutamine
Folate (vitamin B9) and other B vitamins
Betaine
Contrary to popular belief, chiropractic can be used to optimize wellness, not just treat pain. Research suggests chiropractic treatments can help prevent progressive spinal degeneration, i.e. osteoarthritis or disc disease.
Your spinal column, the vertebrae, and the discs, protect your most delicate and important system — your nervous system — and impingements can contribute to a number of health problems and ailments. Hence protecting and nurturing spine will promote greater expression of nerve intelligence and more vibrant health.
Granted, some chiropractors focus primarily on pain and injuries, and do not have the full skill set required to address issues like allergies or disease. So make sure the chiropractor you choose has the appropriate vitalistic philosophy.
