Macular degeneration is one of the most common causes of eyesight loss – and you can reduce your chances of getting it, and even possibly reversing it, by eating a diet that is high in vitamin D.
In a study of identical twins, researchers discovered that those who smoked were far more likely to suffer macular degeneration – and those who ate vitamin D-rich foods, such as oily fish and milk, ran a far lower risk.
The research team, from Tufts Medical Center, also found that the nutrients betaine and methionine helped reduce the risk. Betaine is found in fish, grains and spinach, while methionine is in poultry, fish and dairy.
