Your mother was right. Carrots really can help you see in the dark!
Carrots are an excellent source of beta carotene, the plant form of vitamin A which is needed for healthy vision. In fact, the first symptom of vitamin A deficiency is often night blindness – when the eyes can’t adjust to dim lighting or darkness. A carrot a day is enough to improve night vision if you’re vitamin A deficient, but beware of eating too many carrots – especially if you’re pregnant – because too much vitamin A can damage an unborn baby – or your liver.
Unlike most vegetables, carrots are more nutritious cooked, rather than raw because raw carrots have tough cellular walls which prevent the body from converting 75% of their beta carotene into vitamin A.
