The Coconut oil controversy, is it a healthy “superfood” or hidden danger?

I am going to give you a brief introduction into some of the hot topics surrounding coconut oil as a cure for whatever ails you. I could debate both sides of this argument for hours; trust my poor friends who have patiently listened to me rant about the topic. Today I am presenting a few key points and I’m sure my conscious will cause me to address coconut oil more thoroughly at a later time.

I’m sure you have all heard the hype: Coconut oil is one of the few foods that can be classified as a “superfood.” What exactly is a superfood? Well Google defines a “superfood” as a “nutrient-rich food considered to be especially beneficial for health and well-being.”

What makes coconut oil a “superfood”? Well, it is reported to have traditional medical uses, biochemical properties, help with weight loss, treat cardiovascular disease, and even some neurological conditions. There is much research from doctors and dieticians alike attempting to substantiate or debunk these claims, depending on which side of the fence they sit. It’s truly a hot topic right now and everybody is weighing in. Blogs like “Wellness Mama” have posted titles like 101 Uses for Coconut Oil,[1] and Google is riddled with sites quoting benefits like “Coconut Oil Can Kill Your Hunger, Making You Eat Less Without Even Trying” and “The Fatty Acids in Coconut Oil Are Turned into Ketones, Which Can Reduce Seizures”[2]

Addressing that last claim, there is research currently being conducted to substantiate the efficacy of a “high” fat diet to help prevent epileptic seizures, but that study is still in clinical trials and cannot be classified as a conclusive fact at this point. [3]

Kris Gunners from Authority Nutrition makes many interesting and relevant points in her article 10 Proven Health Benefits of Coconut Oil (No. 3 is Best), but she also quotes the “Coconut Oil Can Improve Blood Cholesterol Levels and May Lower Your Risk of Heart Disease”.[4] Sadly this is where we disagree. Coconut oil is a plant based saturated fat, one of the few fats that come from plants, and the American Heart Association classifies it as a saturated fat. [5]  What does that mean exactly, well basically coconut oil is bonded the same as any other animal fat such as lard or butter. I am on the side of the fence that believes that saturated fats actually lead to elevated cholesterol levels and increased risk of heart disease. I do not mean to pick on Gunners by any means, because she admittedly presents some well-researched and documented support in her article.

I have a hard time swallowing her claims that coconut oil consumption can raise your HDL cholesterol (the good cholesterol) and that saturated fats actually help to lower the bad cholesterol.  The American Heart Association’s Nutrition Committee “strongly advises” following its recommendation of “reducing saturated fat to no more than 5 to 6 percent of total calories”.[6] To me that doesn’t sound like the American Heart Association is promoting the consumption of saturated fats as health foods to reduce cholesterol.

Who else do we turn to for any medical or health related answers? Well WebMD of course! On their website they address the hype that “Coconut oil, according to recent reports, is the latest food cure-all. Claims abound that coconut oil is a health food that can cure everything from poor immune function, thyroid disease, and heart disease, to obesity, cancer, and HIV.”[7]

 What is WebMD’s conclusion on the matter? Very similar to my own personal beliefs, their stance on the issue is that “The evidence that coconut oil is super-healthful is not convincing and these claims appear to be more testimonials than clinical evidence.”[8]

The final issue I have with the big coconut oil debate is “oil pulling” and reported benefits that come from that process. Many people ask me about oil pulling and if it is really all it’s cracked up to be. Honestly, I find the thought of swishing around a saturated fact akin to a mouth full of butter, downright cringe worthy.  I will admit that there are studies that show that this process can kill some of the bacteria in your mouth, if you swish approx. a tablespoon of oil around in your mouth for…20 minutes!!! Yeah no thanks, I would personally rather just use mouthwash and floss.
