Truth or Myth: Do Carrots Improve Vision?
Can carrots really enhance your vision? While optometrists affirm that carrots are made up of large quantities of a beta-carotene that has proven to be beneficial for the eyes, ingesting large amounts of the healthy vegetable will not substitute for glasses or contact lenses.
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, which is composed of a number of antioxidants, protects the surface of the eye to reduce the risk of ocular infections and other infectious illnesses. Vitamin A is also known to be an effective solution for dry eyes as well as other eye disorders.
A deficiency of vitamin A (which is be more likely in poor and developing 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 nutritional source they come from. Retinol is vitamin A that comes from an animal origin such as beef, chicken liver, or dairy products. Vitamin A that is produce-derived comes in the form of 'provitamin A' carotenoids, which convert to retinol after the food is digested. 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 as well as your total health. Even though carrots can't correct vision impairments, mother was right when she said ''eat your vegetables''.
