My recent blog entry about coconut oil generateda lot of comments with the same question: Why isn’t
the Alzheimer’s Association researching coconut oil?
It’s an excellent question and one I get often about
coconut oil and other substances that have been
rumored to help people with Alzheimer’s.
At first glance, the answer is simple: we’ve received
few, if any proposals specifically studying coconut oil.
However, we have received a little over half a dozen
proposals on studies that look at substances derived
from coconut oil such as ketones. Most recently, we
funded a study in 2010 by David Morgan, Ph.D
. from the University of South Florida. Find a
summary of his study here: Ketogenesis and Alzheimer Pathology.Continue reading

Can coconut oil treat Alzheimer’s?
We’ve received quite a few questions recently about whether or not coconut oil can be used to treatAlzheimer’s disease. This is a topic that comes up often, so I thought it would be helpful to provide some background:
The claim
This theory has to do with substances called
ketones. The damage caused by
Alzheimer’s disrupts the brain’s ability to
use its primary energy source, known as
glucose. The brain naturally gets a portion
of its energy from ketone bodies when
glucose is less available (e.g., during
fasting, strenuous exercise, and in
newborns). Ketones may provide an
alternative energy source to the brain’s
cells to moderate the damage caused by
Alzheimer’s disease. The body produces ketones when it metabolizes coconut oil and
similar substances (fatty acids).
Beyond the headline
Unfortunately, there just isn’t any creditable science to support this idea. It is
mpossible
for us to know how well coconut oil does or does not work in Alzheimer’s disease
because there have not been rigorous, large-scale research studies done. Continue

Benefits of Coconut Milk
Coconut milk is extracted by grating mature coconuts and squeezing them by using cheesecloth or both bare hands. This milky white liquid is called santam in Malaysia, Brunei and Indonesia, and gata in Philippines. It is used in several food recipes like sauces, delicious curries and desserts. Apart from making foods tastier and creamier, coconut milk is also a healthy addition to various food preparations.
Nutritional Values of Coconut Milk:
Following are the nutritional values present in 100 grams of fresh coconut milk:

Benefits of Coconut Milk:
Following are some of the health benefits of coconut milk:
Helps to maintain blood sugar places:
Glucose intolerance may cause manganese deficiency in your body. Coconut milk is a rich source of manganese. Whole grains, legumes and nuts are some other excellent sources of manganese.
Keeps skin and blood vessels flexible and elastic:
Copper is a very important mineral for most of the bodily functions. Copper and vitamin C help to maintain the flexibility and elasticity of the skin and blood vessels.
Aids in building strong bones:
Coconut milk is not rich in calcium, but it is rich in phosphorus. Phosphorus is an essential nutrient that the body needs for strengthening bones. It is must to take phosphorus with calcium particularly to prevent bone loss because it supplies phosphate to the body.
Helps to prevent anemia:
Lack of iron is the most common nutrient deficiency among the people throughout the world. Iron deficiency in body does not allow the body to develop enough hemoglobin for keeping sufficient oxygen levels in red blood cells, resulting in anemia. Each cup of coconut milk supplies the body with nearly a quarter of daily value of iron.
Relaxes muscles and nerves:
Whenever you feel muscle cramps or muscle soreness, have some food along with coconut milk. It is rich in magnesium and can help you in relieving the problem. One of the functions of magnesium is it acts as a gate block in many nerve cells. If magnesium is not present in body, nerve cells become very active because of calcium that activates nerves. Excess contraction of muscles is caused by over-active nerve cells.
Helps in Controlling Weight:
This can be good news for people who are trying to reduce weight. Coconut milk makes you feel full very quickly because of high concentrations of dietary fiber.
Decreases the risk of joint inflammation:
Selenium is an important antioxidant. It controls the free radicals and thereby helps in relieving the symptoms of arthritis. It is observed that people with low levels of selenium may suffer from rheumatoid arthritis.
Helps in lowering high blood pressure:
People who are concerned about their blood pressure will not face any problem consuming foods containing potassium. Potassium helps in lowering blood pressure levels in the body.
Helps in maintaining healthy immune system:
Coconut milk helps in warding off colds and coughs by keeping the immune system healthy. It supplies vitamin C to the body which boosts the immune system.
Promotes the health of prostate gland:
Zinc plays a vital role in promoting the health of prostate gland. A preliminary study showed that it slows down the activities of cancer cells.
I hope the above mentioned information helps you in understanding the relation between health and coconut milk. It can also be consumed by people with cow’s milk allergy. It is free from gluten and soy. Hence people who are allergic to these substances can also use coconut milk.

3 reasons why coconut milk may not be your friend
Coconut milk is often a staple fat source for those following a Paleo diet. From a nutritional perspective, it’s an excellent choice. It’s high in saturated fatty acids and medium-chain triglycerides (MCT), which areboth easily burned as fuel by the body. MCTs are particularly beneficial in that they don’t require bile acids for digestion, and they’re directly shunted to the liver via the portal vein.
Coconut milk and fruit can be a great snack for Paleo folks, and coconut milk smoothies make a great Paleo breakfast choice – especially in the summer.
So what could be wrong with coconut milk? Here are three things to consider.
Bisphenol-A
Bisphenol-A (BPA) is a chemical that has been used in consumer goods since the 50s. It’s found in reusable drink containers, DVDs, cell phones, eyeglass lenses, automobile parts and sports equipment. One of the highest sources of BPA is cash register receipts.
We’ve known for decades that BPA has estrogenic activity. In vivo animal studies and in vitro cell-culture research has linked low-level estrogenic activity associated with BPA exposure to all kinds of fun stuff, like diabetes, ADHD, heart disease, infertility and cancer.
Is BPA exposure common? You bet. This CDC report found BPA in the urine of 93% of adults. Perhaps most troubling is that companies like Nestle, Similac, Enfamil and PBM all use BPA in the linings of metal cans holding baby formula. This is scary in light of a recent study which found an association between neurobehavioral problems in infants and high levels of BPA in their mothers.
So why is BPA even legal, you ask? Its safety status is still somewhat controversial. Although I’m not sure how “real” the controversy is.
On the one side you have consumer advocates and independent researchers and scientists who claim that there’s sufficient evidence against BPA, including plausible mechanisms for how it causes harm, to ban it completely. They argue that continued use of BPA in industrial and commercial materials is akin to performing a large, uncontrolled experiment on us all. I tend to agree.
On the other side, you’ve got industry scientists claiming that there’s no significant evidence that low levels of BPA causes harm in humans. If I was a cynic, I might point out that these chemical industry groups are out to protect a multi-billion dollar market from government regulation. Global BPA demand is up to 12 billion pounds and growing at 5% per year.
Okay, back to coconut milk. BPA is used in the lining of certain canned foods. BPA especially leaches into canned foods that are acidic, salty or fatty, such as coconut milk, tomatoes, soup, and vegetables.
So what’s the solution here? In short, if you want to be on the safe side and reduce your exposure to BPA, you have to reduce your consumption of canned foods (including coconut milk) as much as possible. I made this recommendation in 9 Steps for Perfect Health-#3: Eat Real Food.
A study published in Environmental Health Perspectives found that families who ate fresh food for three days with no canned food, and using only glass storage containers, experienced a 60% reduction of BPA in their urine. The reductions were even higher (75%) for those with the highest BPA levels at the beginning of the study.
The good news, however, is that there are at least two brands of coconut milk that don’t have BPA in them. One is Native Forest, which you can purchase on Amazon if it’s not available at your local store. The other is Arroy-D, which is a brand imported from Thailand. You can get it here (but you have to scroll down and order the version that comes in cartons, not the cans at the top). I’m a little suspicious of Arroy-D, though, because one Thai reader mentioned that it does contain other ingredients aside from coconut milk. I don’t read Thai, so I can’t confirm this. If anyone out there can, please leave a comment below.
Coconut milk can also be made quite easily at home, with coconut flakes, a blender and cheesecloth. Here’s a video to show you how (get a load of the soundtrack). I find that blanching the coconut flakes prior to blending improves the results.
Guar gum
The other potential problem with canned coconut milk is guar gum. Guar gum is a galactomannan, which is a polysaccharide consisting of a mannose backbone with a galactose side group. It’s primarily the endosperm of guar beans.
Beans and legumes have a variety of compounds in them that make them difficult to digest, especially for people with digestive problems (1 in 3 Americans, from the latest statistics).
In my clinical experience, many patients with gut issues improve when they remove guar gum from their diet – including canned coconut milk.
Unlike BPA, there’s no evidence that guar gum may cause serious harm. So, if you’re able to tolerate guar gum, I don’t see a problem with buying coconut milk from Native Forest or Arroy-D or making it at home.
Fructose malabsorption
Fructose malabsorption (FM) is a digestive disorder characterized by impaired transport of fructose across the small intestine. This results in increased levels of undigested fructose in the gut, which in turn causes overgrowth of bacteria in the small intestine. Undigested fructose also reduces the absorption of water into the intestine.
The clinical effects of FM include: intestinal dysbiosis, changes in motility, promotion of mucosal biofilm, and decreased levels of tryptophan, folates and zinc in the blood. Symptoms produced include bloating, gas, pain, constipation or diarrhea, vomiting and fatigue (to name a few). Recent research has also tied fructose malabsorption to depression.
Lest you think this isn’t a common problem, studies have shown that up to 40% of people in Western countries suffer from fructose malabsorption.
Even in healthy people without fructose malabsorption, however, only about 20-25g of fructose can be properly absorbed at one sitting. Glucose assists in transport of fructose across the intestine, so in general foods with equal amounts of glucose and fructose will be better absorbed than foods with excess amounts of fructose (in relation to glucose).
While fructose malabsorption can cause symptoms in anyone, those with Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD) are particularly affected. While the prevalence of FM is the same in healthy populations and those with IBS & IBD, the experience of FM appears to be more intense in the latter group. This is probably due to the increased visceral sensitivity common in IBS and IBD patients.
In fact, one of the most promising clinical approaches to treating IBS & IBD right now is something called the FODMAP diet. FODMAP stands for Fermentable Oligo-, Di- and Mono-saccharides And Polyols. These include:
- fructose (fruits, honey, HFCS)
- fructans (wheat, onions)
- lactose (milk sugar)
- polyols (sugar alcohols like sorbitol, xylitol & mannitol, along with fruits like apples, pears and plums)
- galactooligosaccharides (legumes & beans, brussel sprouts, onions)
- other sweeteners like polydextrose and isomalt
Studies have found that restricting FODMAPs can significantly improve the symptoms associated with IBS, IBD and fructose malabsorption.
What does this have to do with coconut milk, you ask? According to Drs. Gibson & Barrett, experts in fructose malabsorption, coconut milk is is a FODMAP and should be avoided by people with digestive conditions like IBS & IBD.
According to NutritionData.com, coconut milk has very little sugar of any kind – including fructose. Nevertheless, I do have patients that cannot even tolerate homemade coconut milk (which has no guar gum in it), even though they are fine with coconut oil. I assume that they are reacting to the fructose in the coconut milk – but I can’t be sure.
Recommendations
Let’s bring this together into recommendations for three different groups of people:
- Women who are trying to get pregnant, pregnant or breastfeeding, children and other vulnerable populations (chronically ill): should avoid canned coconut milk products except for those that are BPA-free, like Native Forest and Arroy-D. Note: Native Forest is organic, but Arroy-D is not.
- People with digestive problems (IBS, IBD, GERD, etc.): may want to avoid coconut products entirely, except for coconut oil
- Healthy people: may be fine with canned coconut milk, provided they don’t react to the guar gum, and provided they’re willing to take the side of industry scientists that claim BPA doesn’t cause harm in humans
Want organic coconut milk – but without the BPA and guar gum?
As of the time of this writing there is no widely available commercial brand of coconut milk that is organic and free of BPA and guar gum. The good news, however, is that with a little extra effort you can easily make this at home yourself.
- Purchase coconut cream (Let’s Do Organic
and Artisana
are good choices) and blend with water to make coconut milk.
- Purchase shredded coconut (again, Let’s Do Organic
is a good choice), and follow the instructions below for making homemade coconut milk.
Homemade coconut milk instructions
Ingredients
- 4 cups water
- 1.5 – 2 cups unsweetened coconut flakes
Instructions
- Heat water until hot (but not boiling).
- Add shredded coconut and water to blender (preferably a Vitamix!
) If all of the water won’t fit, you can add it in two batches.
- Blend on high for several minutes until thick and creamy.
- Pour through a colander to filter out the coconut pulp, then squeeze through a cheese cloth
or nut milk bagto filter the smaller pieces of coconut.
- If you separated the water into two batches, put the strained coconut back into the blender with the second batch of water.
- Drink immediately or store in the fridge. Fresh coconut milk should be used within 3-4 days of making it for the best flavor and texture.
