Coconuts, a staple of tropical islanders, have gained popularity in recent years. This popularity mainly revolves around the health benefits of the oil contained in the coconut. Although high in unfashionable saturated fats, retailers make some weighty claims for the oil, ranging from its ability to eliminate fungal infections to its effects on weight loss.
Extra Virgin Coconut Oil
Coconut oil comes from the edible part of the fruit, also called the coconut meat or copra. Different methods exist to extract the oil from this solid part, with all virgin varieties coming from the fresh copra. Tropical Traditions notes how no industry-wide definitions yet exist; "extra virgin" remains just a marketing label and borrows the tag from olive oil manufacturers. Refined coconut oil, on the other hand, comes from the dried low-grade copra, and undergoes bleaching and deodorizing. Although the fatty acid profile remains similar, only virgin oils retain their coconut aroma.
Fatty Acid
Coconut oil contains a specific type of fatty acid, called medium chain fatty acids. These special fats provide a number of benefits in the human body; researchers from the Weston A Price Foundation note how they reduce cholesterol levels in the bloodstream, and exert potent anti-viral, anti-fungal and antibacterial properties. However, they also play a role in increasing fat burning.
Weight Loss
Following consumption, medium chain fats take a different journey through the body compared to other fats. Dr Bruce Fife, a physician and the author of "The Coconut Oil Miracle," explains how they traveling straight from the intestines to the liver, where they present themselves for immediate oxidation. This increases the amount of fat the liver burns, which can result in weight loss.
Evidence
Japanese researchers investigated the fat-burning properties of the medium chain fats contained within coconut oil. The team, lead by Dr Tsuji, created two groups of volunteers and supplied one with medium chain fats as part of their diet. The results, which featured in the "Journal of Nutrition" in 2001, showed that the group receiving medium chain fats lost 40 percent more weight than their counterparts.
Using Coconut Oil
Coconut oil stands solid at room temperature, but remains a versatile ingredient in a number of recipes. Its saturated fat content affords it a long shelf life and excellent stability under high temperatures, making coconut oil an excellent choice for cooking. Those wishing to use coconut oil for its health benefits can consume it on its own, or add it to teas.
