Tuna sandwiches could protect eyesight
Researchers have discovered that omega-3 fatty acids found in canned tuna and other foods can protect your eyesight in old age.
Every year around 200,000 Britain’s suffer from age-related macular degeneration (AMD) which could effect their vision.
A team of researchers from Brigham and Women’s Hospital and Harvard Medical School in Boston analysed data they had collected from 38,000 women who were not suffering from AMD.
The experts tracked the participants eating habits, omega-3 intake, omega-6 intake and eye health over a ten year period, during which 235 causes of AMD were reported.
Interestingly the researchers found that the women who consumed the most fish oils had a 38 per cent reduced risk of developing AMD when compared to those who ate less.
Dr William Christen who led the study, said: ‘The lower risk appeared to be due primarily to consumption of canned tuna fish and dark-meat fish.’
Though tinned tuna doesn’t contain as much fish oil as fresh tuna or other fish, the finding is significant because such a huge number of individuals eat tuna sandwiches.
