Answer:
Dear
Charles,
Bananas
and oranges are strongly linked with protective eye benefits.
Leafy
green vegetables like kale, spinach, chard and other vegetables contain
high levels of antioxidants as well as vitamin A and beta carotene.
They're
also vital to maintaining healthy vision.
Leafy
green vegetables are good sources of lutein.
Lutein
and zeaxanthin are compounds called xanthophylls, which are carotenoids
related to beta-carotene that gives vegetables like carrots their
orange color.
Lutein
and zeaxanthin add yellow pigment to plants and can be found in the
flesh of colorful fruits and vegetables and in the leaves.
These
two compounds are found in large amounts in the lens and retina of
our eyes.
They
function as antioxidants to potentially help protect our eyes from
damage caused by unstable atoms known as free radicals,
Antioxidants
including beta-carotene, vitamins C and E, and zinc and copper are
vital to maintaining healthy vision.
Oysters
are particularly high in zinc, and a serving will put you over the
recommended daily limit.
Zinc
is found in meat, dairy products, nuts, and seafood.
Keep
in mind that it is surprisingly easy to exceed the recommended upper
limit for zinc intake (40 mg/day),
Constituents
of fruits with potential health eye benefits include flavanoids, fiber,
folate and potassium.
A diet
of fish, nuts and olive oil, and devoid of trans fats like pies and
donuts, could help stave off the eye diseases.
