Recent study has found that diets that include a specific type of omega-3 polyunsaturated fatty acid play a role in positive brain health.
DHA is a polyunsaturated omega-3 fatty acid found throughout the body and it is a major structural fat in the brain.
The Docosahexaenoic Acid (DHA) Oxford Learning and Behaviour (DOLAB) trial is the first large, randomized and placebo-controlled study demonstrating the benefits of this nutrient in reading and behaviour among healthy school children.
The study involved 224 children with baseline reading scores below the 20th percentile. They were supplemented with 600mg of algal DHA for 16 weeks.
The results showed that reading was significantly improved and it led to an additional 0.8 month gain in reading age in those children.
For children with baseline reading scores below the 10th percentile, algal DHA supplementation led to an additional 1.9 month gain in reading age.
The study thus says that DHA helps in maintaining overall health, especially brain health.
