Eye Nutrients: Beta-Carotene & Vitamin A


EYE HEALTH BENEFITS

  • Beta-carotene is converted to Vitamin A in the body, which plays a critical role in the Visual Pathway in our retinal cells. The Visual Pathway is a series of biochemical steps that converts light energy into useful visual information relayed to our brain. Therefore Vitamin A is essential for vision.

  • Vitamin A deficiency can lead to night blindness (nyctalopia)

  • Vitamin A also has an important role in the metabolism of the cornea, and deficiency can lead to severe dry eye (xerophthalmia)


WHOLE-BODY HEALTH BENEFITS

What to Eat:

BETA-CAROTENE: eat orange coloured foods

  • bell peppers, carrots, squash, pumpkin, sweet potato, cantaloupe, papaya

  • broccoli, spinach, zucchini, and other dark, leafy green vegetables are also good sources


Warning: Excessive intake of Vitamin A can be harmful. Smokers should not take supplements containing beta-carotene or Vitamin A as this can increase the risk of lung cancer.


A healthy, balanced diet should provide adequate Vitamin A intake without supplementation.
