Abstract: Based on biochemical and nutritional evidences, lauric acid (C12) has distinctive properties that are not shared with longer-chain saturated fatty acids: myristic acid (C14), palmitic acid (C16), and stearic acid (C18). Because medium-chain saturated fatty acids C6 to C12 show sufficiently different metabolic and physiological properties from long-chain saturated fatty acids C14 to C18, the term “saturated fatty acid” does not convey nutritionally accurate information and chain length should be specified as “medium-chain” and “long-chain”. Many of the properties of coconut oil can be accounted for by the properties of lauric acid. Lauric acid makes up approximately half of the fatty acids in coconut oil; likewise, medium-chain triglycerides which contain lauric acid account for approximately half of all triacylglycerides in coconut oil. It is, therefore, justified to classify coconut oil as a medium-chain vegetable oil. There is no link between lauric acid and high cholesterol.

Abstract: The primary fatty acid of coconut oil is lauric acid, which is present at approximately 45–53 %. The metabolic and physiological properties of lauric acid account for many of the properties of coconut oil. Coconut oil is rapidly metabolized because it is easily absorbed and lauric acid is easily transported. Detailed studies have shown that the majority of ingested lauric acid is transported directly to the liver where it is directly converted to energy and other metabolites rather than being stored as fat. Such metabolites include ketone bodies, which can be used by extrahepatic tissues, such as the brain and heart, as an immediate form of energy. Studies on the effect of lauric acid on serum cholesterol are contradictory. Among saturated fatty acids, lauric acid has been shown to contribute the least to fat accumulation. Lauric acid and monolaurin have demonstrably significant antimicrobial activity against gram positive bacteria and a number of fungi and viruses. Today there are many commercial products that use lauric acid and monolaurin as antimicrobial agents. Because of the significant differences in the properties of lauric acid relative to longer chain fatty acids, they are typically differentiated as medium‐chain fatty acids covering C6–C12, and long‐chain fatty acids covering C14 and longer. 

 

VIRGIN COCONUT OIL METABOLISM AND ITS AFFECTS ON GUT HEALTH AND THE IMMUNE SYSTEM 

Digestion and Absorption of Food Fats 
By: Mary Enig, PhD 
Weston A. Price Foundation, Summer 2004
  

Abstract: Maintenance of a healthy digestive system requires input from lipids, which include molecules such as cholesterol, appropriate saturated and polyunsaturated fatty acids, and other lesser known components such as glycosphingolipids. The digestion of regular fats and oils, which are usually long-chain triglycerides, requires bile acids as well as lipases. In adults this digestion usually starts in the small intestine and is done with the aid of lipases and bile acids. Short- and medium-chain fatty acids from fats such as milk fat or coconut oil or palm kernel oil are broken off from the triglycerides without the need for bile acids. They are then shuttled directly to the liver through the portal artery without the use of chylomicrons. In the case of a meal with a large amount of lauric acid, some of this medium-chain fatty acid does travel via chylomicrons through the lymph system.

Abstract: The gut microbiota is a complex community of a diverse population of obligate and facultative anaerobic microorganisms that could affect host metabolism and immune homeostasis. The effects of virgin coconut oil on the mean weekly fasting glycaemia, weekly body mass gains and daily water and food intakes after 16 weeks, as well as on the changes in composition of caecal microbiota in both non-diabetic and alloxan-induced diabetic rats, were investigated. The beneficial effects of virgin coconut oil were observed for all examined parameters. Additionally, this oil’s potential to positively affect the caecum microbiome, with significant increase in the abundance of beneficial bacteria such as LactobacillusAllobaculum and Bifidobacterium species, was proven.

The Protective Power of Dietary Fats: Fatty Acids and Immune Function 

By: Dr. Bruce Fife, ND, CN.  

Mother’s milk is rich in fats, mostly saturated and monounsaturated fats, with some polyunsaturated fat to supply the infant’s essential fatty acid needs. These fats serve multiple functions; they provide nourishment, help to establish a healthy gut microbiome, and ward off infection and disease. Unlike antibiotics that kill all bacteria, fatty acids are more selective; they can kill the major troublemakers yet leave the good bacteria alone. In this way, potential troublemakers are suppressed while the good microbes are allowed to thrive and firmly establish themselves in the infant’s digestive tract, producing a healthy gut microbiome. 

  

VIRGIN COCONUT OIL: ANTIOXIDANT, ANTI-INFLAMMATORY, & FUNCTIONAL FOOD     

Health and Nutritional Benefits from Coconut Oil: An Important Functional Food for the 21st Century  
By: Mary Enig, PhD 
Presented at the AVOC Lauric Oils Symposium, Ho Chi Min City, Vietnam, 25 April 1996
  

Abstract: Coconut oil has a unique role in the diet as an important physiologically functional food. The health and nutritional benefits that can be derived from consuming coconut oil have been recognized in many parts of the world for centuries. Although the advantage of regular consumption of coconut oil has been underappreciated by the consumer and producer alike for the recent two or three decades, its unique benefits should be compelling for the health minded consumer of today. A review of the diet/heart disease literature relevant to coconut oil clearly indicates that coconut oil is at worst neutral with respect to atherogenicity of fats and oils and, in fact, is likely to be a beneficial oil for prevention and treatment of some heart disease. Additionally, coconut oil provides a source of antimicrobial lipid for individuals with compromised immune systems and is a non-promoting fat with respect to chemical carcinogenesis.

Abstract: We evaluated the protective efficacy of the polyphenolic fraction from virgin coconut oil (PV) against adjuvant induced arthritic rats. Arthritiswas induced by intradermal injection of complete Freund's adjuvant. The activities of inflammatory, antioxidant enzymes and lipid peroxidation were estimated. PV showed high percentage of edema inhibition at a dose of 80 mg/kg on 21st day of adjuvant arthritis and is non toxic. The expression of inflammatory genes such as COX-2, iNOS, TNF-α and IL-6 and the concentration of thiobarbituric acid reactive substance were decreased by treatment with PV. Antioxidant enzymes were increased and on treatment with PV. The increased level of totalWBC count and C-reactive protein in the arthritic animalswas reduced in PV treated rats. Synovial cytology showed that inflammatory cells and reactive mesothelial cellswere suppressed by PV. Histopathology of paw tissue showed less edema formation and cellular infiltration on supplementation with PV. Thus the results demonstrated the potential beneficiary effect of PV on adjuvant induced arthritis in rats and the mechanism behind this action is due to its antioxidant and anti-inflammatory effects.

The Oiling of America

Introduction: In 1954 a young researcher from Russia named David Kritchevsky published a paper describing the effects of feeding cholesterol to rabbits.1 Cholesterol added to vegetarian rabbit chow caused the formation of atheromas—plaques that block arteries and contribute to heart disease. Cholesterol is a heavy weight molecule—an alcohol or a sterol—found only in animal foods such as meat, fish, cheese, eggs and butter. In the same year, according to the American Oil Chemists Society, Kritchevsky published a paper describing the beneficial effects of polyunsaturated fatty acids for lowering cholesterol levels.2 Polyunsaturated fatty acids are the kind of fats found in large amounts in highly liquid vegetable oils made from corn, soybeans, safflower seeds and sunflower seeds. (Monounsaturated fatty acids are found in large amounts in olive oil, palm oil and lard; saturated fatty acids are found in large amounts in fats and oils that are solid at room temperature, such as butter, tallows and coconut oil.)
