The Great Coconut Oil Debate: Is It Truly Beneficial?
Written on
Chapter 1: Understanding Coconut Oil
Recently, I've encountered a surge of online discussions promoting the advantages of coconut oil, which piqued my curiosity. Traditional beliefs often categorize it solely as saturated fat, leading many to question its health benefits. Could it potentially rival olive oil? Or is it akin to eggs, once deemed unhealthy but later vindicated by research (see Mayo Clinic, 2019)? This topic warrants a thorough investigation.
After conducting my research, I aim to share insights from reputable sources.
Section 1.1: An Overview from Healthline
First, I would like to summarize an article from Healthline.com. While I typically view .com sites with skepticism, I acknowledge that some, like nature.com, offer credible information. Healthline employs a medical team to review their articles, which lends some degree of reliability.
Gunnars (2020) outlines “Top 10 Evidence-Based Health Benefits of Coconut Oil.” The term "evidence-based" is encouraging, but upon further investigation, I remain somewhat doubtful.
Subsection 1.1.1: Examining the Claims
Contains Healthy Fatty Acids
The article suggests that coconut oil may enhance fat burning and elevate HDL (good) cholesterol levels due to its medium-chain triglycerides (MCTs), which convert into ketones in the liver, potentially benefiting brain health (e.g., in epilepsy and Alzheimer’s treatment).
However, sources like Harvard T.H. Chan School of Public Health (n.d.) clarify that the coconut oil available in stores contains only a small fraction of MCTs (approximately 13–14%). The predominant fatty acid, lauric acid, is less beneficial. A South Dakota Department of Health researcher noted that to gain MCT benefits, one would need to consume around 10 tablespoons daily—a quantity no one should realistically adopt.
May Enhance Heart Health
The article references studies from Tokelau and Papua New Guinea, where high coconut oil consumption correlates with low heart disease rates.
Yet, Harvard T.H. Chan School of Public Health (n.d.) warns that these studies might overlook other factors, such as overall diet quality, and that the populations studied consume whole coconuts, not processed oil.
May Support Fat Burning
This claim again leans on MCTs rather than coconut oil itself. Gunnars admits, “There’s currently no good evidence to say that eating coconut oil itself will increase the number of calories you expend,” recommending moderation due to its high caloric density.
May Have Antimicrobial Properties
While some studies suggest coconut oil can combat specific harmful pathogens, the evidence remains limited. Furthermore, it does not prevent common colds or internal infections.
May Suppress Hunger
This benefit is again attributed to MCTs rather than coconut oil itself. The studies cited suffered from small sample sizes—one included just six participants.
May Mitigate Seizures
This is likely more aligned with ketogenic diets than coconut oil specifically. None of the studies cited focus on coconut oil, and the overall quality of the research is questionable.
May Elevate HDL Cholesterol
While some studies indicate positive outcomes, they also reveal that coconut oil raises LDL (bad) cholesterol, making the health benefits debatable.
May Benefit Skin, Hair, and Teeth
Topical application of coconut oil does offer benefits, as confirmed by Harvard T.H. Chan School of Public Health (n.d.).
May Improve Brain Function in Alzheimer’s
This point again links back to MCTs, with studies failing to establish a direct mechanism by which coconut oil enhances cognitive outcomes.
May Reduce Harmful Abdominal Fat
The evidence supporting this claim stems from studies with small participant groups, leading to inconclusive results.
Section 1.2: My Conclusion
While the article adopts a generally positive tone regarding coconut oil, it frequently cautions readers that the supporting evidence is weak or inconclusive. The sole clear advantage appears to be its use as a moisturizer for skin and hair. In contrast, other reputable sources remain skeptical.
To summarize, the Mayo Clinic (2019) notes that coconut oil raises both good and bad cholesterol levels more than other plant-based oils, and the MCT content is minimal. Unlike proven heart-healthy fats like olive oil or omega-3 fatty acids, coconut oil's benefits lack robust scientific backing.
As a trained psychological science researcher, I base my assessment on available evidence. While further information may exist, I personally choose not to invest in coconut oil.
