Look alive--eye nutrition
Researchers at the University of Alabama at Birmingham are at it again--this time recommending some foods that might stave off advanced age-related macular degeneration (AMD).
This is the leading cause of blindness in adults.
High fat diets are "associated" with AMD--but we cannot say they "cause" it.
What has a good rep for eyes? Carrots. But beta-carotene, alone, will not do much for eye health.
The key is to maintain vision when going from light to dark. For this, you need fruits and veggies, esp Vitamin C, which can help minimize cataracts.
Fatty acids in fleshy fish such as tuna and salmon protect against AMD.
Red meat and whole grains contain zinc--zinc deficiency can lead to cataracts.
Vegetable oil--Vitamin E, can slow progression of AMD.
So salmon for dinner, orange juice for breakfast, maybe tuna for lunch, a nice steak sometimes. See? Not so bad.
