Traditionally, carrots are known to be associated with the health of eyes. They are thought to improve the eyesight. People who consider carrots good for eyes are not sure what quantity of carrots actually benefits the eyes. They also don’t know whether or not they prevent eye diseases or they help treat pre-existing eye conditions.
It is true that carrots have beta carotene which is converted in the body to ‘retinal’, an important molecule for normal vision. At the same time, it is also important to know that we get adequate dose of beta carotene from our diet even if we don’t eat carrots regularly.
Unless there is a deficiency of vitamin A, which could be caused by various nutritional or medical factors, carrots as such cannot improve vision on their own.
In this context, ‘Age Related Eye Disease Study 2’ conducted by National Eye Institute recommends the consumption of lutein and zeaxanthin along with zinc and vitamin C and E to prevent age-related macular degeneration (AMD) in people over the age of 55.
Good sources of lutein and zeaxanthin are egg yolks, zucchini, spinach, Brussels sprouts and grapes.
Carrots, whether unprocessed of in juice form, may contribute to beta carotene supply to the body needs and may have general health benefits but their role in eyesight maintenance and improvement is overstated. Carrots are good for general health but the health of your eyes can stay normal even if you don’t eat carrots.
