We know that carrots have been eaten for at least 5,000 years from paintings and historical documents. One medium-sized carrot contains 25 calories, 6 grams of carbohydrates and 2 grams of fiber. Carrots are an excellent source of vitamin A, providing more than 200% of your daily requirement in a single carrot. They are usually orange, but they can also be white, yellow, red and purple.
