“Carrots are good for your eyes.” For many people, that bit of wisdom is the sum-total of their knowledge of eye care. But is it true?
The short answer is “yes,” even though most experts recommend dark green leafy vegetables, and not carrots, as the #1 eye food. Carrots do indeed contain very high levels of beta-carotene, which is converted in the body to vitamin A. Vitamin A is essential to the production of a substance called “retinol,” which is critical to the functioning of the retina, the area on the back of the inside of your eyeball that sends messages to your brain that enables you to see.
Actually, liver contains the most carotene/vitamin A. Carrots are second, broccolli is third, and then comes an array of dark green leafy vegetables such as kale, chard, spinach and leaf lettuce (also sweet potatoes). Doctors tend to recommend dark green leafy vegetable over carrots or liver because they contain many nutrients that carrots do not, and they taste better than liver and are far less caloric.
And in case you’re iterested, the inside of the mammalian eyeball contains a fantastically concentrated and diverse nutritional soup of proteins and vitamins. You could survive for a very long time on just water and a couple eyeballs a day.
