New Way to Starve Cancer and Obesity

Dramatically Effective New Natural Way to Starve Cancer and Obesity

Posted By Dr. Mercola | June 08 2010 

William Li discusses a new way to think about treating cancer and other diseases -- anti-angiogenesis, which means preventing the growth of blood vessels that feed a tumor. The crucial step: Eating cancer-fighting foods that beat cancer at its own game.

Dr. Mercola's Comments:

"Angiogenesis" is the process your body uses to build blood vessels. Your body consists of some 19 billion capillaries (the smallest blood vessels), which are the vessels for both life, and yes, in many cases, death, as Dr. William Li, explains during his fascinating TED lecture.

This is because cancerous cells, like all other cells in your body, cannot thrive without the oxygen and nutrients supplied by your capillaries.

Virtually all of your blood vessels are formed while you're in the womb, but there are still certain circumstances in adulthood when your body will grow new blood vessels.

Blood vessels are created each month to form the lining of a woman's uterus, for example. And during pregnancy, new blood vessels form the placenta, which connects and shuttles nutrients to the growing fetus.

"Your body has the ability to regulate the amount of blood vessels it needs at any given time," Li explains, and it does this through an elaborate system of stimulators and inhibitors.

"But for a number of diseases there are defects in this system," Li says.

In some cases, your body becomes incapable of "pruning back" extra blood vessels, and in others it cannot grow enough new ones.

In these situations, angiogenesis is out of balance, and a myriad of diseases result.
For example, insufficient angiogenesis (too few blood vessels) can lead to:

• Chronic wounds that will not heal
• Heart disease
• Stroke
• Neuropathy
• Erectile dysfunction

Excessive angiogenesis (too many blood vessels) promote diseases such as:

• Cancer
• Blindness
• Arthritis
• Endometriosis
• Multiple sclerosis

According to Dr. Li, there are more than 70 major diseases, affecting more than a billion people worldwide -- which on the surface appear completely different from each other -- that all share abnormal angiogenesis as a common denominator.

"This realization allows us to reconceptualize the way we approach these diseases -- by controlling angiogenesis," Li says.

This is exciting, as I believe and have taught for years that your diet is the key to preventing diseases of all kinds, including cancer. Dr. Li's research explains, and scientifically validates what many of us have experienced, and our ancestors intuitively knew.

You are what you eat, and there are vast differences between a historically wholesome, nutritious diet, and the processed, chemical-based foods that pass for sustenance today.

Strategies for Starving Cancer, and Obesity

In his TED talk, Dr. Li focuses primarily on cancer, because angiogenesis is a hallmark of the disease. As stated earlier, cancer cells cannot grow into noticeable tumors without sufficient amounts of capillaries feeding them oxygen- and nutrient-rich blood. 

As it turns out, the majority of people carry around microscopic cancer cell clusters in their bodies, but not everyone actually develops cancer.

This is because as long as your body has the ability to balance angiogenesis properly, it will prevent blood vessels from forming to feed these microscopic tumors. Trouble will only arise if, and when, the cancer cells manage to get their own blood supply, at which point they can transform from harmless to deadly.

"Anti-angiogenic therapy is the method of cutting off blood supply to the cancer," Li explains. "This can be done because tumor vessels, unlike healthy vessels, are abnormal and poorly constructed, and because of that, they're highly vulnerable to treatments that target them."

There are currently about a dozen different anti-angiogenic cancer drugs that, according to Li's statistics, have significantly increased survival rates.

However, the answer to the cancer epidemic is not just devising better drugs to treat it in its advanced stages. The answer is preventing cancer from occurring in the first place, and that's what's so exciting about Dr. Li's research.

Interestingly, obesity is also largely dependent on angiogenesis.

"Like tumor cells, fat cells grow when blood vessels grow," Li says. So in essence, a cancer-preventive diet is also an obesity-preventive diet.

The Cancer-Preventive Diet

Dr. Li believes the answer to cancer is to prevent angiogenesis, which can effectively starve any microscopic cancerous growths, preventing them from growing and becoming dangerous.

But how do you prevent angiogenesis, aside from using a drug?

As it turns out, "mother nature has laced a large number of foods, beverages and herbs with naturally occurring inhibitors of angiogenesis," says Li.

So by consuming these anti-angiogenetic foods you can naturally boost your body's defense system and prevent blood vessels from forming and feeding the microscopic tumors that exist in your body at any given time.

As shown on a graph in the video, diet accounts for at least 30-35 percent of all environmentally caused cancers.

So, "eating to starve cancer" could have a dramatic impact on cancer rates across the world.

According to Li, resveratrol from red grapes, for example, have been shown to inhibit abnormal angiogenesis by 60 percent. Even more potent is the ellagic acid found in strawberries.

Other anti-angiogenetic foods include:

Green tea	Berries: strawberries, blackberries, raspberries, blueberries	Cherries
Red grapes	Kale	Turmeric
Nutmeg	Artichokes	Parsley
Garlic	Tomato	Maitake mushroom

Logically, different foods contain different potencies of anti-angiogenetic compounds. But interestingly, when researchers evaluated a combination of two of the LEAST potent teas, for example, they discovered that this combination tea had greater potency than any given tea by itself.

"There's synergy," Li states, which should come as no surprise to those of you who are well-versed in holistic nutrition.

Synergy is indeed what makes fresh, whole foods so potently nutritious! The sum is far greater than the individual parts, and this is why it's far more important to focus on eating a diet of whole, organic foods, rather than obsessing about individual nutrients.

Some Foods are As Potent, or More Potent than Anti-Angiogenetic Drugs!

In his lecture, Dr. Li shows a graph comparing anti-angiogenetic drugs with foods. It's a beautiful illustration of just how potent foods can be, because, as Li says, "foods hold their own, and in some cases are more potent than the drugs!"

Examples of foods equaling or exceeding the potency of drugs include parsley, garlic, and red grapes.

Dr. Li is now involved with creating the world's first rating system that will score foods according to their anti-angiogenetic, cancer-preventative properties. But there's really no reason to wait for a comprehensive list, because we already know that optimal health hinges on a healthy diet consisting of a wide variety of whole, organic foods.

Just like a single food contains synergistic compounds, and a combination of foods can work together synergistically, a healthy diet overall will help you prevent all manner of disease, including cancer, in more ways than one.

For example, balancing your insulin levels will have a beneficial, protective effect on a number of diseases, including cancer. And eating according to your nutritional type also has potent anti-cancer effects. When we treat cancer patients in our clinic, this is in fact one of the most powerful anti-cancer strategies we have.

Other Important Strategies that Can Help Prevent Cancer

It's virtually impossible to discuss cancer prevention today without discussing vitamin D, as the scientific evidence of its anti-cancerous benefits is truly impressive.

For example, intake of vitamin D3 and calcium could potentially prevent 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer annually in the United States and Canada, according to a complex computer prediction model.

This model also predicted that 75 percent of deaths from these cancers could be prevented with adequate intake of vitamin D3 and calcium.

Theories linking vitamin D to certain cancers have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory studies, according to epidemiologist Cedric Garland, DrPH, professor of family and preventive medicine at the UC San Diego School of Medicine.

Dr. Garland is widely regarded as the leading epidemiologist on vitamin D and its relation to health. He led one of the latest studies on vitamin D for cancer prevention and proposed a new model of cancer development -- dubbed DINOMIT-- that is centered on a loss of cancer cells' ability to stick together.

The model is a departure from the older model of cancer development, which centers on genetic mutations as the earliest driving forces behind cancer. According to Dr. Garland:

"The first event in cancer is loss of communication among cells due to, among other things, low vitamin D and calcium levels. In this new model, we propose that this loss may play a key role in cancer by disrupting the communication between cells that is essential to healthy cell turnover, allowing more aggressive cancer cells to take over."

So clearly, no cancer prevention plan is complete without this simple lifestyle modification.

Normalizing your vitamin D levels with safe amounts of sun exposure is one of the most effective, and least expensive, strategies that is available to most people. Ideally, you'll want to monitor your vitamin D levels to make sure your levels stay within a therapeutic range year-round.

Here are several additional strategies you can incorporate to virtually eliminate your cancer risk:

1. Control your insulin levels by limiting your intake of processed foods and sugars as much as possible.
2. Get appropriate amounts of animal-based omega-3 fats.
3. Exercise. One of the primary reasons exercise works is that it drives your insulin levels down. Controlling insulin levels is one of the most powerful ways to reduce your cancer risks.
4. Have a tool to permanently erase the neurological short-circuiting that can activate cancer genes. Even the CDC states that 85 percent of disease is caused by emotions. It is likely that this factor may be more important than all the other physical ones listed here, so make sure this is addressed. My particular favorite tool for this purpose, as you may know, is the Emotional Freedom Technique.
5. Only 25 percent of people eat enough vegetables, so by all means eat as many vegetables as you are comfortable with. Ideally, they should be fresh and organic. However, please understand that, frequently, fresh conventionally grown vegetables are healthier than organic ones that are older and wilted in the grocery store. They are certainly better than no vegetables at all, so don't use that as an excuse. If you are a carb nutritional type you may need up to 300 percent more vegetables than a protein nutritional type.
6. Maintain an ideal body weight.
7. Get enough high-quality sleep.
8. Reduce your exposure to environmental toxins like pesticides, household chemical cleaners, synthetic air fresheners and air pollution.
9. Boil, poach or steam your foods, rather than frying or charbroiling them.

Cancer's Favorite Food - Found in Everything You Eat?

Pancreatic tumor cells use fructose to divide and proliferate, according to a study that challenges the notion that all sugars are the same.

Tumor cells fed both glucose and fructose used the two sugars in two different ways. This could explain why other studies have previously linked fructose intake with pancreatic cancer, one of the deadliest cancer types.

According to MSNBC:

"Americans take in large amounts of fructose, mainly in high fructose corn syrup, a mix of fructose and glucose that is used in soft drinks, bread and a range of other foods. Politicians, regulators, health experts and the industry have debated whether high fructose corn syrup and other ingredients have been helping make Americans fatter and less healthy." 

According to Reuters

Study shows fructose used differently from glucose

* Findings challenge common wisdom about sugars

WASHINGTON Aug 2 (Reuters) - Pancreatic tumor cells use fructose to divide and proliferate, U.S. researchers said on Monday in a study that challenges the common wisdom that all sugars are the same.

Tumor cells fed both glucose and fructose used the two sugars in two different ways, the team at the University of California Los Angeles found.

They said their finding, published in the journal Cancer Research, may help explain other studies that have linked fructose intake with pancreatic cancer, one of the deadliest cancer types.

"These findings show that cancer cells can readily metabolize fructose to increase proliferation," Dr. Anthony Heaney of UCLA's Jonsson Cancer Center and colleagues wrote.
"They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth."

Too much sugar of any kind not only adds pounds, but is also a key culprit in diabetes, heart disease and stroke, according to the American Heart Association.

Several states, including New York and California, have weighed a tax on sweetened soft drinks to defray the cost of treating obesity-related diseases such as heart disease, diabetes and cancer.

The American Beverage Association, whose members include Coca-Cola (KO.N) and Kraft Foods (KFT.N) have strongly, and successfully, opposed efforts to tax soda. [ID:nN12233126]

The industry has also argued that sugar is sugar.

Heaney said his team found otherwise. They grew pancreatic cancer cells in lab dishes and fed them both glucose and fructose.

Tumor cells thrive on sugar but they used the fructose to proliferate. "Importantly, fructose and glucose metabolism are quite different," Heaney's team wrote.

"I think this paper has a lot of public health implications. Hopefully, at the federal level there will be some effort to step back on the amount of high fructose corn syrup in our diets," Heaney said in a statement.

Now the team hopes to develop a drug that might stop tumor cells from making use of fructose.

U.S. consumption of high fructose corn syrup went up 1,000 percent between 1970 and 1990, researchers reported in 2004 in the American Journal of Clinical Nutrition.

Dr. Mercola's Comments:

Are all sugars equal in terms of the health effects they produce?

Sooner or later, science will put this debate to rest once and for all. It's already been conclusively shown that fructose, most commonly consumed in the form of high fructose corn syrup (HFCS), is FAR more hazardous to your health than regular sugar, but the corn industry still vehemently denies such claims.

Through successful PR campaigns, industry has managed to pull the wool over your eyes for some time now, but eventually even they will have to surrender to the scientific evidence...

Until then, propaganda machines like the Corn Refiners Association's site, SweetSurprise.com, will continue telling you that "research confirms that high fructose corn syrup is safe and no different from other common sweeteners like table sugar and honey. All three sweeteners are nutritionally the same," and that "though the individual sugars are metabolized by different pathways, this is of little consequence since the body sees the same mix of sugars from caloric sweeteners, regardless of source."

But are these metabolic differences of little consequence?
Far from it!

Fructose Speeds Up Cancer Growth

Research just published in the journal Cancer Research shows that the way the different sugars are metabolized (using different metabolic pathways) is of MAJOR consequence when it comes to feeding cancer and making it proliferate.
According to the authors:

" Importantly, fructose and glucose metabolism are quite different... These findings show that cancer cells can readily metabolize fructose to increase proliferation."

In this case, the cancer cells used were pancreatic cancer, which is typically regarded as the most deadly and universally rapid-killing form of cancer.

The study confirms the old adage that sugar feeds cancer because they found that tumor cells do thrive on sugar (glucose). However, the cells used fructose for cell division, speeding up the growth and spread of the cancer.

If this difference isn't of major consequence, then I don't know what is.
Whether you're simply interested in preventing cancer, or have cancer and want to live longer, you ignore these facts and listen to industry propaganda at your own risk.

How Does Sugar Feed Cancer?

Controlling your blood-glucose and insulin levels through diet, exercise and emotional stress relief can be one of the most crucial components to a cancer recovery program. These factors are also crucial in order to prevent cancer in the first place.

It may surprise you, but the theory that sugar feeds cancer was born nearly 80 years ago. Even more shocking, most conventional cancer programs STILL do not adequately address diet and the need to avoid sugars.

In 1931 the Nobel Prize was awarded to German researcher Dr. Otto Warburg, who first discovered that cancer cells have a fundamentally different energy metabolism compared to healthy cells.

Malignant tumors tend to use a process where glucose is used as a fuel by the cancer cells, creating lactic acid as a byproduct.^[i] The large amount of lactic acid produced by this fermentation of glucose from cancer cells is then transported to your liver. This conversion of glucose to lactic acid generates a lower, more acidic pH in cancerous tissues as well as overall physical fatigue from lactic acid buildup.^{[ii] [iii]}

This is a very inefficient pathway for energy metabolism, which extracts only about 5 percent of the available energy in your food supply. In simplistic terms, the cancer is "wasting" energy, which leads you to become both tired and undernourished, and as the vicious cycle continues, will lead to the body wasting so many cancer patients experience.

Additionally, carbohydrates from glucose and sucrose significantly decreases the capacity of neutrophils to do their job. Neutrophils are a type of white blood cell that help cells to envelop and destroy invaders, such as cancer.
In a nutshell, ALL forms of sugar are detrimental to health in general and promote cancer, but in slightly different ways, and to a different extent. Fructose, however, clearly seems to be one of the overall most harmful.

Connecting the Dots: Fructose—Uric Acid—Cancer and Chronic Disease Risk

One particularly interesting tidbit I noticed in this latest study is the mention of how fructose metabolism leads to increased uric acid production along with cancer cell proliferation.

In my first interview with Dr. Johnson, he explained just how detrimental the impact of fructose is on your uric acid level. Interestingly, ONLY fructose, NOT glucose, drives up uric acid as part of its normal metabolic pathways.
And, the connection between fructose, uric acid, hypertension, insulin resistance/diabetes and kidney disease is so clear that your uric acid level can actually be used as a marker for toxicity from fructose -- meaning that if your levels are high, you're at increased risk of all the health hazards associated with fructose consumption and you really need to reduce your fructose intake.

For more information about this topic, please see this link.

Dr. Richard Johnson has written one of the best books on the market on the health dangers of fructose, called The Sugar Fix, which explains how fructose causes high blood pressure, heart disease, obesity, diabetes and kidney disease. As I've mentioned previously, he does promote the use of artificial sweeteners in this book, which I cannot recommend. His research on fructose, however, is unsurpassed in my opinion.

Now it's safe to say that cancer, at least pancreatic cancer, is also definitely on the list of diseases that are directly linked to excessive fructose consumption.

So are Fruits Good or Bad for You?

This recommendation has created much controversy among many who regularly consume fruit and believe this recommendation does not apply to them.

Many who eat large amounts of fruit have no symptoms, just as those with high blood pressure may not have any symptoms. However lack of symptoms is no assurance you are not exposing yourself to some danger.

Please remember that over three-quarters of the population has insulin resistance.

How do you know if you have insulin resistance? If you have any of the following conditions it is a safe bet you have it:

• Diabetes
• High blood pressure
• Overweight
• High Cholesterol
• Cancer

If you have insulin resistance it would be strongly recommended to limit your total grams of fructose from fruit to below 15 grams per day (see the table below). If you believe you are very healthy and are an exception to this recommendation, then you can easily confirm if this is true for you by measuring your uric acid level.

If your uric acid level is greater than 5.5 than you have a risk factor and should limit your fructose consumption. The higher over 5.5, the stronger the risk factor is.

Keep in mind that fruits also contain fructose, although an ameliorating factor is that whole fruits also contain vitamins and other antioxidants that reduce the hazardous effects of fructose.

Juices, on the other hand, are nearly as detrimental as soda, because a glass of juice is loaded with fructose, and a lot of the antioxidants are lost.

It is important to remember that fructose alone isn't evil as fruits are certainly beneficial. But when you consume high levels of fructose it will absolutely devastate your biochemistry and physiology. Remember the AVERAGE fructose dose is 70 grams per day which exceeds the recommend limit by 300 percent.

So please BE CAREFUL with your fruit consumption. You simply MUST understand that because HFCS is so darn cheap, it is added to virtually every processed food. So even if you consumed no soda or fruit, it is very easy to exceed 25 grams of hidden fructose in your diet if you are consuming anything processed.

If you are a raw food advocate, have a pristine diet, and exercise regularly, then you could be the exception that could exceed this limit and stay healthy. But in my experience that is certainly the exception and not the norm.

So please, carefully add up your fruits based on the table below to keep the total fructose from fruit below 15 grams per day.

Fruit	Serving Size	Grams of Fructose
Limes	1 medium	0
Lemons	1 medium	0.6
Cranberries	1 cup	0.7
Passion fruit	1 medium	0.9
Prune	1 medium	1.2
Apricot	1 medium	1.3
Guava	2 medium	2.2
Date (Deglet Noor style)	1 medium	2.6
Cantaloupe	1/8 of med. melon	2.8
Raspberries	1 cup	3.0
Clementine	1 medium	3.4
Kiwifruit	1 medium	3.4
Blackberries	1 cup	3.5
Star fruit	1 medium	3.6
Cherries, sweet	10	3.8
Strawberries	1 cup	3.8
Cherries, sour	1 cup	4.0
Pineapple	1 slice (3.5" x .75")	4.0
Grapefruit, pink or red	1/2 medium	4.3

Restricting Fructose Consumption is Crucial Part of a Comprehensive Cancer Treatment Plan

Reducing (or preferably eliminating) fructose and other added sugars, as well as limiting grain carbohydrates from your diet, is usually a primary priority on my list of cancer reducing strategies, and for good reason.

This dietary strategy should also be part of your comprehensive cancer treatment plan.

By severely reducing your intake of fructose and carbs in your diet, you help stave off any potential cancer growth, and "starve" any tumors you currently have.

It also bolsters your overall immune function, because sugar decreases the function of your immune system almost immediately.

Unfortunately, few cancer patients undergoing conventional cancer care in the US are offered any scientifically guided nutrition therapy beyond being told to "just eat healthy foods." I believe many cancer patients would see major improvement in their outcome if they controlled the supply of cancer's preferred fuel, glucose, and stayed clear of fructose to significantly reduce tumor proliferation.

Starving Cancer – Another Up-and-Coming Strategy

Before I go into further cancer prevention strategies, I'd like to remind you of another recent cancer research development I recently wrote about, namely 'starving' cancer by eating foods that prevent angiogenesis.

Angiogenesis (too many blood vessels) is a hallmark of cancer as the tumor actually needs blood in order to grow (this is how it feeds on the glucose in your bloodstream). But angiogenesis appears to be preventable by consuming foods that are natural inhibitors of excessive blood vessel growth.

When you regularly consume these foods, you can effectively starve any microscopic cancerous growths, effectively preventing them from growing further and becoming dangerous.

According to Dr. Li, who is currently leading this research, resveratrol from red grapes, for example, have been shown to inhibit abnormal angiogenesis by 60 percent. Even more potent is the ellagic acid found in strawberries.
(See:

Angiogenesis - Dr. William Li's 2010 TED Talk (Vid...

Anti-Angiogenic Cancer Research (Video 6:37)  )

Other potent anti-angiogenetic foods include:

Green tea	Berries: strawberries, blackberries, raspberries, blueberries	Cherries
Citrus: oranges, grapefruit, lemons	Kale	Turmeric
Nutmeg	Artichokes	Parsley
Garlic	Tomato	Maitake mushroom

Logically, different foods contain different potencies of anti-angiogenetic compounds. Some foods have even been found to be more potent than current anti-angiogenetic drugs! These include parsley and garlic.

But interestingly, when researchers evaluated a combination of two of the LEAST potent teas, for example, they discovered that this combination tea had greater potency than any given tea by itself.

"There's synergy," Li states, which should come as no surprise to those of you who are well-versed in holistic nutrition.

It is this synergy that makes fresh, whole foods so potently nutritious!

The sum is far greater than the individual parts, and this is why it's far more important to focus on eating a diet of whole, organic foods, rather than obsessing about individual nutrients.

Other Cancer Prevention Strategies

Aside from avoiding fructose and other added sugars (which means cutting out not only soda and sugary beverages, but also processed foods since most are loaded with HFCS), and incorporating more anti-angiogenetic fare into your diet, here are several additional strategies you can incorporate to virtually eliminate your cancer risk:

1. Normalize your vitamin D levels with safe amounts of sun exposure. This is one of the most effective, and least expensive, cancer prevention strategies available to most people.
