Added: 20 Aug 2013 A thought-provoking study from the Cardiovascular Journal of Africa states that more than half of the omega-3 fish oil supplements on the South African market do not contain the claimed EPA and/or DHA (two types of omega-3s) contents as stated on product labels. The study also showed that 73% are in the early stages of oxidation (rancidity).
Added: 20 Aug 2013 An omega-3 rich diet from fish or flaxseed oil could "substantially and significantly" reduce the signs and symptoms of osteoarthritis, according to new research published in the Osteoarthritis and Cartilage Journal. There is also strong evidence to suggest that omega-3s could potentially help slow the progression of the disease in cases where it is already established, as well as prevent it
Added: 20 Aug 2013 A clinical trial assessing how different omega 3 fatty acids are processed by the body “suggests that dietary ingestion of plant-derived omega 3 fatty acids is sufficient to meet the dietary needs of humans”. ALA is properly and sufficiently converted by the body into EPA and DHA.
Added: 20 Aug 2013 A study of vegans and vegetarians who don’t eat fish shows that their bodies contain as much EPA and DHA as regular fish-eaters. Vegans and strict vegetarians get all their dietary omega 3 in the form of the plant-based ALA. The study shows that the body easily converts ALA to EPA and DHA.
Added: 20 Aug 2013 The ratio of total:HDL cholesterol is a better indicator of coronary artery disease than “bad” LDL levels alone. A recent study from the American Journal of Clinical Nutrition concludes that lauric acid, a fatty acid found mainly in coconut oil, has a “more favourable effect on the ratio of total:HDL cholesterol than any other fatty acid, either saturated or unsaturated”.
