Diet & Prevention
Exercise daily to keep your body and immune system strong. Consume larger quantities of foods high in lutein and zeaxanthin; these substances are potent antioxidants. Foods high in these compounds include carrots and dark, green leafy vegetables like kale, green leaf lettuce and beet greens. Egg yolks, squash, peaches, and sweet potatoes are also good sources.
It is best to avoid eating raw and uncooked foods like salad and sushi; greasy or fried foods like chips, fries, and cheese; and pungent or heavily seasoned foods like kimchi, curries, and barbeque. No shrimp and shellfish. Avoid chocolate. No smoking, alcohol, coffee and cold beverages.
