1.WHAT IS OMEGA-3?
Omega−3 fatty acids, also called ω−3 fatty acids or n−3 fatty acids, are polyunsaturated fatty acids (PUFAs) characterized by a double bond three atoms away from the terminal methyl group. They are widely distributed in nature, being important constituents of animal lipid metabolism, and they play an important role in the human diet and in human physiology. The three types of omega−3 fatty acids involved in human physiology are α-linolenic acid (ALA), found in plant oils, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both commonly found in marine oils. Marine algae and phytoplankton are primary sources of omega−3 fatty acids. Common sources of plant oils containing ALA include walnut, edible seeds, clary sage seed oil, algal oil, flaxseed oil, Sacha Inchi oil, Echium oil, and hemp oil, while sources of animal omega−3 fatty acids EPA and DHA include fish, fish oils, eggs from chickens fed EPA and DHA, squid oils, and krill oil.
Omega−3 fatty acids are important for normal metabolism. Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds). The ability to make the longer-chain omega−3 fatty acids from ALA may be impaired in aging. In foods exposed to air, unsaturated fatty acids are vulnerable to oxidation and rancidity. Dietary supplementation with omega−3 fatty acids does not appear to affect the risk of death, cancer or heart disease.
2 . Health Effects
There are many, many health benefits of Omega 3. It’s good for our brains and eyes and it helps keeps our joints and skin healthy. In 2008, the American Journal of Clinical Nutrition published three studies that showed low concentrations of EPA and DHA in elderly people resulted in an increased risk of death from all causes.
Omega 3 can benefit, and is recommended for, a whole host of health conditions. They range from joint problems like rheumatoid arthritis as well as skin disorders such as eczema and acne. There are also hundreds of promising trials charting the positive effects of Omega 3 on Alzheimer’s, ADHD, depression, blood pressure and children’s learning and behaviour.
