As we all know, carrots contain vitamin A in the form of beta carotene and can considerably boost eye health. The liver converts beta-carotene into vitamin A and then this compound goes to the retina and becomes rhodopsin, a substance necessary to healthy night-vision. Aside from that, carrots are a high source of antioxidants that can help reduce your risk of various forms of temporary illnesses and serious chronic diseases. Higher intake of carrots also decreases the risk of cadriovascular disease, helps protect against cancer and the potassium present in carrot juice can reduce cholesterol levels. For those of you who like to party, the good new is that carrot juice cleanses and detoxifies the liver, so it's a great 'morning after' drink to cure that awful hangover.
