New proof daily dose of fish oil does help keep your brain young

Eating fish helps keep your brain young, claim scientists.
They found diets lacking an essential nutrient in oily fish may hasten brain shrinkage and mental decline. People eating the least amount of omega-3 fatty acids had less brain mass - equivalent to about two years of chronological ageing.
Low levels of omega-3 fatty acids were also associated with poor test scores for visual memory, problem solving, multi-tasking and abstract thinking. It is thought that omega-3 fatty acids in fish oils may reduce inflammation of the brain and play a part in brain development and nerve cell regeneration. Britons are currently advised to eat fish at least twice a week, including one portion of oily fish.
In a new study, brain scans carried out on 1,575 people with an average age of 67 showed a greater rate of brain shrinkage in those who lacked docosahexaenoic acid (DHA).
DHA is an omega-3 fatty acid that is thought to help nerve cells communicate with each other. The richest source of the nutrient is oily fish, such as herring, mackerel and sardines.
