Coconut Oil Secret - Best Healing Superfood
The MCT used for commercial purposes are usually derived from lauric fats, which are found primarily in palm kernel oil and coconut oil. In the process of producing MCT, lauric oils are hydrolyzed to MCFFA and glycerol. The glycerol is drawn off from the resultant mixture, and the MCFA are fractionally distilled. The MCFA fraction used commercially mainly consists of caprylic or octanoic acid (65-75 C8) and capric or deca-noic acid (25-35 C10). Smaller amounts of caproic or hexanoic acid (1-2 C6) and lauric acid (1-2 C12) exist in commercial products (Babayan, 1987).
Conventional fats and oils are composed of glycerides of 12- to 18-carbon long-chain fatty acids (LCFA). These compounds are known as long-chain triglycerides (LCT) and are the predominant form of lipids in the diet. Lipids are an essential source of energy and essential fatty acids, and a vital component of body cells. Therefore, it would be beneficial to have a dietary fat with the added benefit of anti-obesity properties. Medium-chain triglycerides (MCT) have a number of unique characteristics relating to energy density, absorption and metabolism, which give them advantages over the more common LCT. Upon hydrolysis, MCT yield medium-chain fatty acids (MCFA) caproic (C6), caprylic (C8), capric (C10), lauric (C12) (Papamandjaris et al., 1997). Naturally occurring sources of MCT are rare, but include milk fat, palm kernel oil, and coconut oil. Human consumption of MCT is currently low but intake should perhaps be greater due to the distinctive properties of MCT, which cause an...
Consequently, longer studies to assess the impact of MCT on EE were undertaken. White et al. (1999), fed 12 non-obese, premenopausal women a diet containing 40 of energy as fat, either in the form of butter and coconut oil or beef tallow, over 14 days. On day 7, mean BMR and PP EE values were significantly greater with the MCT diet than with the LCT diet. On day 14, PP total EE was still greater with the MCT diet, but not
Studies in animals and humans have shown that MCTs have a greater thermogenic effect than LCTs in the short term, probably due to their rapid oxidation (reviewed in reference 108). Longer studies in animals and humans have shown that consumption of MCTs instead of LCTs can result in less body weight gain and decreased size of fat depots.108-110 Coconut oil is particularly rich in MCTs, and we found in rats that a coconut-oil enriched diet was particularly effective in stimulating BAT UCP1 expression during ad libitum feeding and in preventing UCP1 down-regulation during food restriction, and that these effects went hand in hand with a decrease in the mass of white fat stores.111 Furthermore, data suggest that MCT consumption increases satiety more than LCT consumption.108109
Coconut Oil - The Healthy Fat
The coconut tree is one of the most versatile plants in existence. Whilst we are all familiar with the coconut as a food source not many of us know the myriad of other benefits the coconut holds.
