Tuck In: Eating Fish Helps Protect Your Eyes

Here's another great reason to eat sushi. Women who regularly eat fish - particularly oily fish - have a far lower risk of developing an eye disease when they're older that can cause blindness, say US researchers.

Writing in the journal Archives of Ophthalmology, the Boston-based scientists claim the omega-3 fatty acids found in oily fish such as tuna, mackerel, trout, herring and sardines could slash your risk of developing age-related macular degeneration (AMD).

AMD is the most common cause of sight loss in this country among people over the age of 50, with around 200,000 Brits affected each year. It affects the central part of your vision, specifically the macula (a small part of your retina).

The study tracked more than 38,000 women over the course of ten years. And comparing the diets of those who went on to develop AMD with that of those who didn't, the researchers discovered the women who ate oily fish once a week or more were 42% less likely to develop the disease than those who ate oily fish less than once a month.

Particularly interesting was the fact that the lower risk was strongly associated with eating dark-meat fish, such as tuna - which means that lunchtime favourite, a tuna and mayo sandwich, is a real eye health boost.

There again, tinned tuna - most commonly used for making sandwiches - is lower in fish oils than fresh, which suggests eating tuna sushi or any dish with fresh tuna may be even better for your vision than a sarnie.
