Nutritional and Medicinal Uses of Virgin Coconut Oil

What is Commercial Coconut Oil?
It is the oil mechanically extracted from the kernel (endosperm) of the coconut Copra is the kernel material after separating the shell (endocarp It is an RBD oil (refined, bleached and deodorized) High heat and chemicals may be used to produce this oil
Composition of Coconut Oil
Saturated Fatty Acid Medium Chain Fatty Acids (MCFA) Lauric acid (50%)
Composition of Coconut OilCommon name Caproic acid Caprylic acid Capric acid Lauric acid Myristic acid Palmitic acid Stearic acid Oleic acid Linoleic acid others Composition C 6:0 C 8:0 C 10:0 C 12:0 C 14:0 C 16:0 C 18:0 C 18:1 C 18:2 C 18:3 C 24:1 Mean % 0.44 7.05 6.59 50.63 18.10 8.26 3.07 4.65 0.8 0.31
Do not contain double bond
1 double bond
2 or more double bonds
Physico-chemical value of Saturated & Unsaturated FA
Straight configurationMore stable Long shelf life
Curved configurationUnstable Need to be hydrogenated to for longer shelf life
Hydrogenation of Fats
Transforms into longer shelf life for MUFA
Straightens the curve configuration High risk fat
Creates TRANS-FATTY ACIDS
Lowers the level of HDL Raises the level of LDL Leads to obesity, diabetes and immunologic problems
VEGETABLE LARD = HYDROGENATED FAT
VIRGIN COCONUT OIL IS NOT HYDROGENATED FAT
Trans Fatty Acids During Pregnancy and After Pregnancy
Effect on the pregnant woman
Increases the risk of pre-eclampsia Displace essential fatty acids needed for brain and nervous tissue development Interferes with growth and development Significantly changes the composition of human milk by displacing the essential fatty acids
Effect on the fetus Effect on the newborn
Effect on the mothers milk
Importance of Carbon Chain Length in Fatty Acids
Medium Chain Triglycerides
Contain 6 12 carbon atoms Rapidly absorbed
Does not require pancreatic or bile salt digestion prior to absorption Directly taken up by the hepatocytes and directly converted to MC Acyl CoA and enters into the mitrochondria without the aid of carnitine
Does not get stored as fat
also known as n-dodecanoic acid and nalkanoic acid is a the main fatty acid in coconut oil with structural formula CH3(CH2)10COOH has a very low toxicity and so is used in many soaps and shampoos and other cosmetic products
What is VCNO?
Mechanically pressed and heated to remove moisture Cold pressed / cold and centrifuged Enzymatic extraction No added chemical on the final product
Nutritional and Medicinal Value
Weak Evidence for weight loss and to increase athletic performance helpful in some cancers and may have some positive effects on immunity.
Nutritional and Medicinal Value
Strong Evidence for nutritional support in enteral and total parenteral nutrition in some infants and surgical patients those who are critically ill with immunosuppression, pulmonary disease, liver disease, neurologic injury and various malabsorption syndromes useful in some with epilepsy and other disorders characterized by seizures.
Dermatologic/ Cosmetic Use
Emmolients Moisturizer Shampoo Soap Psoriasis Fungal Disease
Base for most cosmetic products
Skin Infections/ Diseases
What are the present problems with the use of VCNO as food supplement?
No standard dose to recommend The definitive effect on cholesterol is still not clear The side effects, such as diarrhea, are still undocumented
What are the present problems with the use of VCNO as medicine?
Lack of controlled clinical trials on specific diseases
Infectious diseases viral or bacterial Diabetes Cancer
Lack of controlled clinical trials on specialized pediatric nutrition
Low birth weight infants/ Pre-term SGA
