At first glance, I see only marketing ingenuity of an expensive product. Anything that is a “cure all” or a “miracle food” has me seeing the infamous glaring red flag. There are claims that coconut oil promotes weight loss, dissolves kidney stones, protects against prostate cancer and now there are claims that it might even help suppress or cure Alzheimer’s disease. In addition, you can buy 32 oz. of coconut oil for $40.00. What a bargain!!!!????
I set out to investigate my hunch through clinical findings and common sense.
As long as I can remember, I have known coconut oil and palm oil as the “tropical oils”, which are saturated fats, and the two least healthy oils to consume. Clinical evidence shows that saturated fat in the diet directly correspond to the triglycerides in your blood, which directly corresponds to your LDL (bad cholesterol) in your blood. Heart disease is connected to LDL and saturated fats. Saturated fats contribute to clogging your arteries (arteriosclerosis) overtime. Connect that evidence with the fact that heart disease is the number one killer of adults in the United States.
Coconut oil is 92% saturated fat. More specifically, 1 tablespoon of coconut oil has more saturated fat than found in steak or bacon in equal portions. It is used for commercial frying and in candies and margarines, as well as in non-edible products such as soaps and cosmetics.
According to the U.S. Department of Agriculture:
The difference in the triglyceride make up of plant based coconut oil is softer than most animal fats because of the shorter carbon chains. The medium chain triglycerides (MCTs) are the “fat burning” contributor the marketing gurus have honed in on to sell coconut oil. Most other oils have more long chain triglycerides.
Researcher, Marie-Pierre St-Onge of Columbia University explains that "MCTs are transported directly from the intestinal tract to the liver, where they're likely to be directly burned off as fuel and raise the metabolic rate slightly." That means less is available to be circulated throughout the body and deposited in fat tissues. This research has led to several studies on dieters using coconut oil.
Keep in mind that there are holes in every study. Somebody used a bazooka with these. Can coconut oil help you lose weight? There is no good evidence.
In the largest and longest of St-Onge's studies, she and her colleagues told 31 overweight or obese men and women to eat 1,500-to-1,800-calorie-a-day diets with 12 percent of their calories coming either from MCTs (1½ to 2 tablespoons a day of MCT oil) or from olive oil. (Olive oil, by the way, is made up of monounsaturated fatty acids, which are considered heart healthy fatty acids, unlike saturated fatty acids.) The fatty acids in olive oil may help lower your risk of heart disease by lowering total cholesterol and your LDL levels. I have never in my life read that about a saturated fat; neither animal nor plant based.
In her four month study, the people getting MCT oil lost about four more pounds than those getting olive oil. There's no way to tell whether the MCT users would have continued to lose more weight beyond four months. In addition, St-Onge said that "The effect of MCT oil on weight loss is modest."
Studies looking at heart disease in humans as related to coconut oil consumption are scarce. There is one study done in people in the last 17 years, Malaysian researchers found that when they fed young men and women 20 percent of their calories from coconut oil for five weeks, LDL ("bad") cholesterol was 8 percent higher and HDL ("good") cholesterol was 7 percent higher than when the participants were fed 20 percent of their calories from olive oil.
Regarding these findings, Frank Sacks, professor of cardiovascular disease prevention at the Harvard School of Public Health in Boston said "We know that raising LDL levels increases the risk of heart disease," however, “we can't say that raising HDL with diet or drugs can lower the risk of cardiovascular disease." Sacks' bottom line: "Since polyunsaturated oils lower LDLs and coconut oil raises LDLs, we can't recommend that people replace olive, canola, or other liquid oils with coconut oil."
Consider that when certain populations are studied, their overall diet will contribute to the results of the study. If a population eats mostly plant foods and fish, like islanders would do, then the results are most likely to show healthy results than if the study were conducted in a less healthy diet population. Overall diet is a significant factor to any study and results!
There is no good evidence that coconut oil can help you lose weight or cure Alzheimer's disease. Keep in mind that the more direct correlation to preventing Alzheimer’s disease is a healthy diet rich in dark and colorful vegetables, whole grains, lean meats in moderation and exercise. Sound familiar? Diet and exercise reduces risk factors of just about every disease.
As my blog title suggests, I am going to support my initial suspicion that coconut oil, a saturated fat, is being marketed by the best. My recommendation is that you stick with unsaturated fats and oils such as olive oil and canola oil. They can lower LDL and have a positive effect on your health. Eating a diet rich in saturated fats, which usually come from animal-based foods, can increase your LDL cholesterol. As always, moderation is the key player. Unsaturated fats are the right choice. So enjoy your steak...OCCASIONALLY; and eat your veggies and salads with a little bit of olive oil!
