We have all been told that carrots help you see better, but is it the truth? Eye care professionals know that regardless of how many carrots you eat, they can't prevent you from needing eye glasses. However, carrots do contain substantial quantities of beta-carotene, a vitamin that is beneficial for your eye health and therefore eating foods rich in beta-carotene is definitely recommended for ensuring eye health.
Beta-carotene is a carotenoid, or orange pigment that converts into vitamin A once digested in the human body. Vitamin A helps to guard the cornea, or surface of the eye, and has been shown to prevent a number of eye diseases such as corneal ulcers. Vitamin A, a group of antioxidant compounds, protects the surface of the eye to reduce the frequency of ocular infections as well as other infectious diseases. Vitamin A has also shown to be a successful treatment for dry eye syndrome as well as other eye disorders. A deficiency of this important vitamin (which tends to exist more in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can lead to complete blindness.
Two forms of vitamin A exist, which relate to the food source they come from. Retinol is vitamin A derived from an animal origin such as beef, chicken liver, whole milk or cheese. Vitamin A that is derived from fruits and vegetables comes in the form of ''provitamin A'' carotenoids, which are converted to retinol after the nutrients are absorbed. In addition to carrots, carotenoids can be found in colorful fruits and vegetables particularly those that are bright orange or green in color.
It is proven that vitamin A contributes to the health of your eyes and your overall health. Even though carrots themselves won't correct vision impairments, grandma was right when she advised ''eat your vegetables.''
