What is the best food to prevent presbyopia?



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.
