Coconut Oil 101: 13 Studies on Coconut Oil and Its Health Benefits

coconut oil – Coconut oil has been the focus of various health researches over the years, primarily for its touted health benefits. Whether used in cooking, skincare, or hair care, coconut oil has found its place in different corners of our lives. However, how far does the scientific backing go to support its health benefits? This article aims to explore 13 notable studies on coconut oil and its health benefits.

1. Lauric Acid and Heart Health:

One of the most concentrated sources of lauric acid, a medium-chain fatty acid, is found in coconut oil. A 2010 study published in the journal Lipids reported that dietary supplementation with coconut oil could increase HDL (‘good’) cholesterol and decrease waist circumference, a risk factor for heart disease, in coronary artery disease patients.

2. Coconut Oil and Alzheimer’s Disease:

In a 2014 study published in the Journal of Alzheimer’s Disease, coconut oil demonstrated potential benefits for Alzheimer’s patients. The study suggested that coconut oil could provide an alternative energy source for brain cells, which could theoretically improve symptoms of Alzheimer’s disease.

3. Coconut Oil and Weight Loss:

A 2009 study published in the Journal of Lipids found that coconut oil supplementation could assist in weight loss efforts, primarily due to its impact on increasing energy expenditure and fat burning.

4. Skin Health and Coconut Oil:

A study published in the journal Dermatitis in 2004 reported that coconut oil could improve skin hydration and lipid barrier function, making it a natural and effective moisturizer.

5. Antimicrobial Properties:

Lauric acid in coconut oil has been found to have potent antimicrobial properties. A 2007 study in the Journal of Medicinal Food concluded that coconut oil could be used as a novel antimicrobial agent against several pathogenic microorganisms.

6. Hair Damage Prevention:

Our hair is subjected to various forms of damage every day, from exposure to the sun’s harsh UV rays to the thermal stress of heat styling tools, not to mention chemical treatments like coloring and perming. All these can lead to hair damage characterized by breakage, split ends, dryness, and dullness. However, studies have suggested that coconut oil can be an effective and natural solution to counter these issues.

A seminal study published in the Journal of Cosmetic Science in 2003 explored the benefits of coconut oil for hair health, particularly its ability to prevent hair damage. The researchers conducted a controlled study wherein they pre-treated hair with coconut oil before subjecting it to common damaging procedures, such as washing, UV exposure, and combing.

The study revealed that coconut oil has an exceptional ability to reduce protein loss, which is the main form of damage for both undamaged and chemically treated hair. But how does coconut oil manage to do this?

It’s down to the molecular structure of the oil. Coconut oil is predominantly made up of a medium-chain fatty acid called lauric acid. This type of fatty acid has a straight linear chain, and it’s small enough to penetrate the hair shaft. This allows it to protect both the outer layer of hair, known as the cuticle, and the inner core of the hair, known as the cortex, by preventing water from entering and causing hygral fatigue, a common cause of hair damage.

Furthermore, coconut oil’s hydrophobic nature provides a protective barrier, limiting the amount of water absorbed and reducing the likelihood of hair swelling and contracting, which can lead to structural damage.

These findings suggest that regular use of coconut oil in your hair care routine can provide a protective effect. However, it’s essential to note that the quantity of coconut oil used and the duration of treatment can depend on your hair type and health. Some people may experience greasiness or heaviness when using coconut oil, so it’s crucial to find a balance that works for your hair.

7. Coconut Oil and Digestion:

A 2020 study in the journal Gut Pathogens indicated that the antimicrobial properties of coconut oil could assist in balancing gut microbiota, thereby improving digestion.

8. Insulin Resistance:

A 2009 animal study published in the Journal of Medicinal Food suggested that virgin coconut oil could reduce insulin resistance, making it potentially beneficial for people with type 2 diabetes.

9. Immune Function:

A study in the 2010 issue of the Journal of the American College of Nutrition found that the lauric acid in coconut oil could help boost the immune system due to its antimicrobial and anti-inflammatory properties.

10. Coconut Oil and Liver Health:

A 2011 animal study published in the Journal of Basic and Clinical Physiology and Pharmacology found that virgin coconut oil could protect against liver damage.

11. Antioxidant Properties:

A study in the 2013 Asian Pacific Journal of Tropical Medicine concluded that virgin coconut oil had antioxidant properties, which could potentially protect the body from harmful free radicals.

12. Metabolic Syndrome:

A 2015 study published in the journal Applied Physiology, Nutrition, and Metabolism found that the use of coconut oil could potentially mitigate metabolic syndrome, a cluster of conditions including increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels.

13. Coconut Oil and Bone Health:

A 2012 animal study in the Evidence-Based Complementary and Alternative Medicine journal indicated that coconut oil could prevent bone loss, suggesting potential benefits for bone health.

While these studies show potential benefits of coconut oil, it’s important to remember that more research is needed, especially in humans. Coconut oil is high in saturated fat, and overconsumption may have adverse health effects. Always consult a healthcare provider before making significant changes to your diet or supplement routine.

In conclusion, coconut oil may be more than just a kitchen staple. With benefits ranging from enhancing heart health to potentially assisting in weight loss, it is emerging as a promising part of a balanced diet and a healthier lifestyle. However, like everything else, moderation is key.
