DHA (Docosahexaenoic acid) is a long-chain omega-3 fatty acid. Studies show that it plays an important role in the visual and cognitive development of infants as well as helping to reduce the risk of cardiovascular disease. It is predominantly found in wild catch oily fish and algal oil.
What is omega-3 DHA?
The nutritional importance of omega-3 DHA
There are three principal health benefits attributed to the consumption of the long chain omega-3 PUFAs, EPA and DHA:
Brain development and cognitive function
Omega-3 DHA is critical to the development of the brain and optimal cognitive function in infants, and has a continued role for children. Breast milk provides at least 50mg of DHA to babies each day. Based on the rate of accumulation in the human brain, there is a need to supply DHA either via breast milk or fortified infant formulas during the first year of life. The role of omega-3s in behavior, learning and maintenance in older children and the elderly is also emerging.
Developmental and maintenance role in visual acuity
Omega-3 DHA has long been known to be important for visual function. The highest concentration of DHA found in the human body is in the retina. Studies investigating the effects of food enriched with DHA on visual development in infants have found that feeding infants DHA-supplemented food from 6 months of age results in better visual function by 12 months of age compared to the control (non-DHA-supplemented) infants.
Cardiovascular health and disease prevention/recovery
Omega-3s have a direct influence on reducing the risk of heart disease by preventing irregularities in the rhythm of the heart, protecting against the formation of plaques in arteries and reducing blood pressure. Key studies also demonstrate the role of omega-3s in reducing sudden death by up to 45% in people who had previously experienced a heart attack.
