Coocoo for Coconut Oil: Think Again

Like butter, coconut oil is high in saturated fat. Saturated fats may cause blood cholesterol levels to rise and increase your risk of developing heart disease. The 2020-2025 Dietary Guidelines for Americans advise limiting your intake of saturated fat.
Here’s a summary of some of the evidence behind a few of the more common health claims associated with coconut oil.

Helping with Weight Loss

Some weight-loss programs tout coconut oil because it contains medium chain triglycerides, or MCTs. Advocates for MCTs claim it promotes weight loss, increases metabolism and reduces belly bloat. However, the research is limited. More research is needed on other changes that may have been made during the same time period, as these could have promoted those changes. For example, if individuals ate fewer calories and exercised more.

Controlling Type 2 Diabetes

Diabetes causes the level of glucose, or sugar, in your blood to rise above the normal level. Animal studies suggest that coconut oil may be beneficial for managing blood sugar. However, most findings have been in animal studies and may not be the same for humans. If you have Type 2 diabetes, treat coconut oil like any other saturated fat and limit your intake by choosing foods that are higher in unsaturated fat.

Reversing Alzheimer's Disease

The link between brain health and coconut oil stems from the MCTs. Glucose, which your body gets from the foods you eat, is the main source of energy for the brain. Some researchers believe the brains of people with Alzheimer's disease do not efficiently break down glucose for energy. Therefore, their brains need an alternative source of energy. One theory is that the MCTs found in coconut oil may be able to provide that backup energy source. Research suggests there may be some benefits for individuals with Alzheimer’s who consume MCTs; however, not all types of brain function improved. More research is needed.

What the Research Shows

What is known is that coconut oil is high in saturated fat. And, diets high in saturated fat may raise cholesterol levels in the body, which could increase your risk for heart attack and stroke.

Research shows that replacing saturated fats, such as coconut oil, with polyunsaturated fats and monounsaturated fats, such as olive oil, is beneficial for overall health.
