Healthy diet may help prevent vision loss

A new study, from Tufts University School of Medicine in Boston, found that older adults who eat a diet rich in citrus fruits, leafy greens, and fish oil, but low in "glycemic index," may have a lower risk of AMD, a leading cause of vision loss.

The study also found that those who ate food with a low glycemic index, or those that create a gradual increase in blood sugar like soybeans and yogurt, also appeared more protected from AMD.

Researchers say foods like citrus fruits, leafy greens, and salmon are also beneficial for overall health.
