Eating oily fish can delay the breakdown of brain cells in later life, slowing the ageing process, a study has found.

People with higher levels of omega-3 fatty acids, found in fish like salmon and anchovies, also preserve bigger brains as they aged, research revealed.

In particular, they maintain more nerve cells in the hippocampus, the brain's key memory centre.

Scientist Dr James Pottala, from the University of South Dakota said: "Results suggest the effect on brain volume is the equivalent of delaying the normal loss of brain cells that comes with ageing by one to two years."
