Though there have been more than a thousand papers published on coconut oil in medical journals, there is little evidence it helps with Alzheimer’s disease.
Those that sell coconut oil claim it has miraculous powers—everything from X, Y, and Z. The boldest claim may be as a potential cure for Alzheimer’s, based on a series of anecdotes and one study. Study of the ketogenic agent AC-1202. You can certainly make money selling 20 pound buckets of coconut oil, but even more selling some kind of patented supplement, which is what this is, a concentrated form of the medium chain fatty acids, purported to be the active ingredient in coconut oil. At first it looked like it was working, but by the end of the study any effect it had had disappeared, though there was one genetic subgroup where it appeared to be working better, but when that group was properly randomized even that effect disappeared. So the only such study ever done on concentrated coconut oil components found little effect and no studies have ever been done whatsoever on Alzheimer's and coconut oil itself. As the Alzheimer’s Association put it, there is no scientific evidence that coconut oil helps with Alzheimer’s. And hey, the coconut oil promise has been around for more than three years. If the administration of coconut oil was, indeed, beneficial, it would presumably be shouted from every mountaintop." That's all we know so far. Why don't we know more? There have been over a thousand articles published on coconut oil in the medical literature, the problem is that they’re studies like this. Did you know coconut oil enhances tomato carotenoid tissue accumulation compared to safflower oil in the Mongolian gerbil? Which includes nuggets like this: "The testes of the coconut oil-fed animals weighed significantly less than those of the safflower oil-fed animals. Who says coconut oil isn't effectual? How else are you going to shrink the testicles of Mongolian gerbils?

The "shouted from every mountain top" argument is not entirely convincing. For example, we've known for decades that our #1 killer is preventable and reversible (see Resuscitating Medicare, Our Number One Killer Can Be Stopped, and China Study on Sudden Cardiac Death), yet the medical community continues to rely more on drugs and surgery. Why? Well they likely weren't taught clinical nutrition in medical school (Medical School Nutrition Education), or after medical school (California Medical Association Tries to Kill Nutrition Bill), and the medical establishment has shown a disturbing inertia even when presented with convincing evidence (see The Tomato Effect). The difference is that coconut oil doesn't have the data to back it up. What's the potential downside of giving coconut oil a try? Find out in my next video Does Coconut Oil Clog Arteries?
