How eating oily fish can prevent you going blind | Mail Online

A diet rich in oily fish could hold the key to preventing blindness among thousands of the elderly, research has found.

The omega-3 group of fatty acids, found in oily fish such as salmon, mackerel and fresh tuna, may help protect against the most common form of sight loss among older people, it suggests.

Scientists studying the diets of adults over the age of 65 found those who regularly ate seafood were far less likely to develop age-related macular degeneration, which is caused by the death of cells in the retina.
