While carrots often get all the attention when it comes to eye health, guava offers a broader and more potent range of vision-supporting nutrients. Its effectiveness stems from its exceptionally high levels of compounds that directly protect the cells of the retina and lens.
The synergy between vitamin A and vitamin C: protection and repair
Guava is an exceptional source of two vitamins essential for eye health:
Vitamin C (Ascorbic Acid):
Guava can contain four to five times more vitamin C than an orange. This powerful antioxidant is concentrated in the fluids of the eye, where it prevents oxidative stress that leads to cataracts and macular degeneration. It also aids in the production of collagen, essential for the structure of the cornea.
Vitamin A (Beta-Carotene):
Guava is packed with carotenoids that the body efficiently converts into vitamin A (retinol). Retinol is essential for vision; it is a component of rhodopsin, the light-sensitive protein in the retina. Without enough vitamin A, night vision and overall retinal function are impaired.
