May protect your vision in old age

A leading cause of visual impairment and blindness in older adults is age-related macular degeneration (AMD). Fish and omega-3 fatty acids, according to some evidence, may protect against this condition.

Regular fish consumption was linked to a 42% decreased risk of AMD in women in one research. Another study discovered that eating fatty fish once a week reduced the risk of neovascular ("wet") AMD by 53%. Or in one study of 681 elderly American men found that eating fish twice a week reduced the risk of macular degeneration by 36%. People who ate fish just once a week lowered their risk by 40% in the other research, which followed 2,335 Australian men and women for five years.
