There are lots
of reasons you have been told to eat a healthy diet. Eating plenty of leafy
greens and omega-3 rich foods are well recognized for their role in
cardiovascular health, cancer prevention and weight management , but vegetables
also contribute a significant source of vitamins and nutrients for your eye
health. Research shows that several diseases of the eye, including cataracts,
glaucoma and macular degeneration—all of which are more common as you age, can
be reduced with a healthy diet that includes fruits, vegetables and some types
of fish.
Vitamin C: Protects some
parts of the eye from the damaging effects of ultraviolet (UV) light. Most men
and women meet the basic daily requirements for vitamin C (between 75 and 90
milligrams per day), but some people may need higher doses to help prevent some
eye conditions. Your doctor will be able to guide you further.
Sources for vitamin C: strawberries, brussel sprouts, broccoli, mango,
and raspberries
Vitamin E: A powerful antioxidant, vitamin E may play a role
in the prevention of macular degeneration, and the formation of cataracts.
Vitamin E is a fat-soluble vitamin and how much you take will be guided by your
doctor. You may be able to take in enough vitamin E through diet and not need
an extra vitamin.
Sources for vitamin E: cottonseed oil, hazelnuts, almonds, fortified
cereal, and sunflower seeds
Zinc: This trace mineral is highly concentrated inside
the eye and supports the health of the retina—an area of the eye that collects
light. Levels seem to drop as you age, so it is important to take in more
through your diet.
Sources for zinc: garbanzo beans, black-eyed peas, sunflower seeds,
milk, beef and chicken
Omega-3:
Found in every cell in the body, these healthy fats
are essential for the health of many systems. Omega-3 rich foods have been
shown to slow the progression of macular degeneration, diseases of the retina,
and improve dry eyes.
Sources for omega-3: seafood, flaxseed oil, nuts and seeds, spinach,
broccoli and fish oil supplements
