The Science Behind Coconut Oil
In the 1930s, Dr. Weston Price discovered that the South Pacific Islanders incorporated high quantities of coconut in their diet but remained healthy and fit, and there was a low incidence of heart disease. In 1981, researchers learned that Polynesian communities whose primary source of food was coconut remained in excellent cardiovascular health. Coconut oil is naturally high in medium chain triglycerides and lauric acid. While coconut oil is one of the few known natural sources of lauric acid, it’s also found in mother’s milk, increasing immune strength of infants. More recently, research shows that coconut oil can support cardiovascular health, immune health, skin health, hair health, weight management and performance enhancement.
- Recent research has indicated that not all saturated fats increase the risk of heart disease. Studies show that virgin coconut oil can improve cholesterol levels by decreasing low-density cholesterol and increasing high-density cholesterol in serum and tissues.

- Research shows that lauric acid can increase our body’s production of monolaurin, enhancing anti-bacterial protection.
- Studies also suggest that virgin coconut oil has anti-inflammatory and analgesic and properties.

- Studies show that coconut oil can improve atopic dermatitis, an inflammatory itchy skin condition, by acting as an effective moisturizer.
- Virgin coconut oil can also be used as a moisturizer to provide relief for mild to moderate xerosis.
- Virgin coconut oil when topically applied to wounds, promotes speedy healing.

- Coconut oil treats damaged hair by penetrating into hair fibers and acting as a moisturizer. When coconut oil is used as a pre-wash and post-wash grooming product, it can reduce protein loss for both damaged and healthy hair. The lauric acid present in coconut oil has an affinity for hair proteins and because of its low molecular weight it can penetrate the hair fibers and prevent hair damage.

- A study conducted on women revealed that coconut oil promotes reduction in abdominal obesity.
- Consuming medium chain triglycerides can increases diet-induced thermogenesis, which can contribute to preventing weight gain or regain, and in some cases may induce weight loss.
- When compared to most vegetable oils that contain long-chain triglycerides (LCTs), medium-chain triglycerides (MCTs) found in coconut oil are used for energy production and are not stored as fat. Partial replacement of LCTs with MCTs can reduce accumulation of fat.

- Studies show that MCTs are easily digested and rapidly absorbed into the blood stream from the GI tract upon consumption, and are efficiently utilized by the body for energy production, improving performance of athletes.
