Oil with multiple uses

19 November 2013

By Tan Bee Hong

Palm oil plays a larger role in our lives than we realise. Tan Bee Hong finds out more


PALM oil is, without doubt, an integral part of our lives. You may not even be aware of its presence. When you brush your teeth, the toothpaste you use may contain palm oil. Then you sit down to breakfast. You may add non-dairy creamer to your cup of coffee. That’s definitely made with palm oil. Then you spread margarine on a slice of bread and fry an egg. Both margarine and oil are palm oil–based.

After you shower (with soap and shampoo made with palm oil) you put on skincare and lipstick. Yes, made with palm oil. Believe it or not.

Throughout the day, the meals you eat will mostly be cooked with palm oil.

Indeed, there really is much more to the use of palm oil than meets the eye.

Palm oil has been used for over 5,000 years by humans who valued its health benefits. In Egypt, it was considered a sacred food ingredient and was so prized that jars of it had been found entombed with the pharaohs.

Medical circles have also recognised the value of red palm oil in the treatment and prevention of malnutrition and vitamin deficiency. Because of this, governments, particularly those in Third World countries, have been using it for decades to combat vitamin deficiency diseases which are rampant in poor communities.

These include use of palm oil as a cooking oil, so that the people will get a dose of the vitamin-rich oil on a daily basis. It is also used for baking. Providing school-going children daily with a cookie or biscuit enriched with palm oil, for instance, will go a long way to improve health among the impoverished. After all, palm oil is an excellent oil for cooking and baking as it contains 50 per cent saturated fatty acids, 40 per cent monosaturated fatty acids and 10 per cent polyunsaturated fatty acids. This composition is the reason why palm oil is stable and highly heat resistant as well as has a high smoke point of 225° Celsius.

Palm oil is also rich in Vitamin E (tocopherols and tocotrienols). No other vegetable oil contains as much Vitamin E, a powerful anti-oxidant that helps fight free radicals in the body. Vitamin E is also helpful in lowering the risk of certain chronic diseases and delaying the body’s ageing process.

According to Dr Bruce Fife, an author, speaker, certified nutritionist, and naturopathic physician, “red palm oil not only supplies fatty acids essential for proper growth and development, but it is packed with an assortment of vitamins, antioxidants, and other phytonutrients important for good health. Red palm oil gets its name from its characteristic dark red colour. The colour comes from carotenes such as beta-carotene and lycopene — the same nutrients that give tomatoes and carrots and other fruits and vegetables their rich red and orange colours”.

Continuing modern research is revealing that the antioxidants found in red palm oil can be of help in protecting against a variety of health problems including osteoporosis, asthma, cataract, macular degeneration, arthritis and liver disease.

Palm oil comes from the fruit of the oil palm (Elaesis guineensis), a native plant in Africa which is today, grown in the hot, humid equatorial belt, particularly Southeast Asia, West Africa and South America. Malaysia is one of the world’s largest producer and exporter of palm oil.

While the fruit of the oil palm produces two types of oil, one from fibrous outer layer called mesocarp and another from the fruit kernel, it is the former that we usually refer to when speaking about palm oil. Crude palm oil has lots of residue and a strong, pungent smell. It needs to be refined and processed to create oil for use in the various forms.

During the Japanese Occupation of Malaya, the people in rural areas depended largely on palm oil for daily use.

Home economist and queen of nyonya cuisine Florence Tan, told me that the people then had little choice. After all, oil palm fruit was more easily available but the crude oil extracted, was smelly and had to be sieved first before it can be considered for use.

Today, red palm oil is readily available on supermarket shelves under the brand name Carotino.

“I first saw Carotino when it was first introduced into the market. It reminded me immediately of the crude palm oil that we had to make do with during the Japanese Occupation,” says Florence.

“Everything was in short supply then and our Malay neighbours in Malacca told my parents to try the palm oil, saying it’s very nutritious. Of course in those days, it was just crude palm oil and was rather smelly as it wasn’t processed.”

Today, she is a great advocate for the use of palm oil. “I use it every day. It’s great for making salad dressings like Thousand Island. I use it to bake breads and carrot cake. Oh, you should see the colour of the carrot cake... beautiful!

When you fry eggs with it, it adds a lovely sheen... and use it for fried rice and tomato rice,” she says enthusiastically.

She admits there are certain limitations, especially where Chinese style stirfried green vegetables are concerned, or dishes like Cantonese fried noodles. “But you can use it for mixed vegetables with no problems,” she says.

“When the Chinese see the oil, they immediately think of the red-coloured oil used to light prayer lamps. At that time, everybody thought corn oil and sunflower oil were the best. But now, the younger generation is much more receptive and they know which oil is better for their health.”

Trans fats make palm oil more popular in the US

29 November 2013

By Dr. Ahmad Ibrahim              

DESPITE all the available scientific evidence, published in peer-reviewed journals, there are still groups questioning palm oil's health status.


At a recent talk by Dr Kalyana Sundram, from the Malaysian Palm Oil Council (MPOC), we were told there are now initiatives brewing in Europe to discredit palm oil.

At one time, such adverse comments on palm oil were confined only to the United States.

However, nowadays, consumers in the US, after learning about the new science of palm oil nutrition, are now much less negative.

Much of the shift in perception can be traced back to the revelation in the early 1990s about the negative health consequences of trans fats. That proved to be a rude awakening for US critics of palm oil.

Prior to the findings linking trans fats to heart disease, all earlier blame was placed on saturated fats.

Labels on saturated fats content of food products were then made compulsory.

That was a challenging time for palm oil since it contains 50 per cent saturates. But now the blame is on trans fats. How things can change.

What exactly are trans fats? How are they produced? What is the scientific evidence that has led to the conclusion that they are not good for health? What has been the impact of the revelations on fat choices in the US? What has been the consequence on palm oil use in the US? Why is palm oil now the preferred fat in a country where at one time it was even branded as poison?

Actually trans fats are not new. They have been around since man started making margarine and shortening to replace butter.

Butter was getting rather expensive during the war years. It was also hard to come by. Someone developed an alternative to butter by a process called partial hydrogenation of seed oils. The product was margarine.

It was unfortunate that palm oil was not around then. If not, palm oil would have been ideal for making margarine because of its natural semi-solid property. At that time, palm oil was produced on a small scale by small farmers in West Africa.

Not much of palm oil was traded then. The little that was traded was mainly exported from West Africa to Europe. Most ended as either lubricating oil or in making soap. This explains why many outside the palm oil producing states in West Africa knew little about palm oil. Palm oil only started making its appearance on the international scene when Malaysia invested in palm oil in a big way.

When seed oils like soya or sunflower are partially hydrogenated to harden the fats, trans fats are produced. And this has been consumed in large amounts in all kinds of products, including biscuits and confectionery.

Interest in investigating the role of trans fats came when scientists could not understand why despite the low consumption of saturated fats in the US, the incidence of heart diseases continued to rise.

Some curious nutritionists took a closer look at trans fats. And what they found was most surprising to many. They came out with very convincing data that trans fats are worse than saturates when it comes to raising cholesterol in the body.

The studies that were done showed that trans fats not only raised the bad cholesterol, but also suppressed the good cholesterol.

There was disbelief at first. But eventually the evidence was too convincing to ignore. Labelling of trans fats soon became mandatory.

More consumers became aware of the deleterious nature of trans fats. And palm oil was seen as the optimal option for margarine and shortening manufacturers to suppress the content of trans fats in their products.

Gradually, palm oil was seen in a better light. And exports of palm oil to the US started showing signs of increasing. Next, we were told that trans fats will eventually no longer be classified as GRAS (generally regarded as safe). That will surely deliver more good news for palm oil exports to the US.

Now trans fats have quickly earned the name "a silent killer" and is to be avoided at all cost! One thing is for sure. Trans fats make palm oil even more popular.

Sea Cucumber Found to Kill 95% of Cancer Cells, Shrink Tumors

sea cucumber cancer 263x164 Sea Cucumber Found to Kill 95% of Cancer Cells, Shrink TumorsSea cucumber has been used in traditional Chinese medicine for hundreds of years, but they are relatively obscure in the U.S. This may be soon changing, however, as evidence mounts that sea cucumber extracts can kill cancer cells while stimulating the immune system.

As reported by Ethan Evers, author of “The Eden Prescription, previous research on sea cucumber has demonstrated its ability to kill lung, breast, prostate, skin, colon, pancreatic, and liver cancer cells. These extracts have also proven effective in killing leukemia and gioblastoma cells. Looks like we can add yet another food to the list of anti-cancer foods.

Scientists believe a key compound known as frondoside A to be responsible. Frondoside A is a triterpenoid, diverse organic compounds found in the essential oils and oleoresins of plants.

 This latest study, published in PLoS One, has confirmed just how powerful frondoside A truly is. Researchers found it to kill 95% of ER+ breast cancer cells, 95% of liver cancer cells, 90% of melanoma cells, and 85-88% of three different types of lung cancer.

As Evers reports:
“But the benefits of this compound don’t just stop at directly inducing programmed cell death (apoptosis). It also inhibits angiogenesis (the ability of tumors to grow new blood vessels to get their food) and stops cancer metastasizing by impeding cell migration and invasion. Even more intriguing is the ability of frondoside A to activate our immune system’s natural killer cells to attack cancer cells. This has been shown for breast cancer in particular but may also apply to all cancers, because it involves the immune system and not cancer cells directly. This may partially explain why frondoside A was so effective at shrinking lung tumors in mice that it rivaled chemo drugs in performance.”
When given to mice with non-small cell lung cancer, frondoside A was found to shrink tumors by 40% in only 10 days. Traditional chemo drugs shrunk the tumors by 47 percent, but the risks of chemo treatment are far greater than any side-effects or risks of sea cucumber. (Namely because there are no known risks associated with sea cucumbers). In addition, the amount of frondoside A needed to achieve such results was miniscule—less than a single milligram for an adult weighing 165 pounds.

While sea cucumber extracts aren’t currently offered as a treatment for cancer—at least not in your traditional doctor’s office—you can find dried and powdered sea cucumber in health stores. It is packaged as a solution to arthritis and similar conditions because of its anti-inflammatory properties.
