So what does the science say? [ Music ] >> Hi! Dr. Bernie here, and welcome to Practice Impact Extra.
Cardiovascular disease remains the leading cause of death worldwide. Dyslipidemia is one of the most important modifier risk factors for the development of cardiovascular disease. However, there remains controversial evidence regarding various oils and their effect on LDL cholesterol and other CV risk modifiers. There was a meta-analysis performed in September 2018, which compared coconut oil to various other non-tropical oils.
Researchers concluded that coconut oil was effective in lowering LDL compared to lard and butter. This study has been touted by many as a supportive case for coconut oil's positive health benefit claims. However, when you really take a look at this meta-analysis, they had a significant limitation in their results, citing that 40% of the trials included in their meta-analysis had significant bias, which resulted in rating the credibility of evidence as low, as well as only six of the trials that they included had coconut oil for comparison.
So those a little bit concerning, so I continued to look and see if there's anything new. And I really found in the literature some evidence to clarify regarding coconut oil. And in January of 2020, a new assessment was published on coconut oil and its relationship to cardiovascular disease and this was published in the Journal circulation. This meta-analysis included 16 published studies that demonstrated that coconut oil substantially increased LDL cholesterol by nearly 10% or about 10 milligrams per deciliter.
The likely explanation is though coconut oil is a medium chain fatty acid, its main component is lauric acid, which is metabolized similar to long chain fatty acid. Coconut oil, as you're aware, contains 25% of two other long chain fatty acids. Further results and analysis of these studies noted that coconut oil did not significantly affect other markers that were thought to be positive. It didn't affect glucose levels and didn't affect inflammation, as compared to non-tropical vegetable oils.
So what's the take-home message here? The scientific evidence suggests that there is no apparent significant benefit of coconut oil in improving health and may potentially increase cardiovascular disease risk in individuals.
