Answer:
Vitamin A in large doses as a supplement has been shown to have a potentially negative effect on fetal development. Carrots and vegetables, on the other hand, do not contain vitamin A itself but carotene. Carotene is provitamin A and is converted to vitamin A in your body only if your body needs it.
You cannot get too much Vitamine A by eating Carotene because the body regulates conversion from carotene to Vitamin A. Although carotene is converted to vitamin A in the body, excessive ingestion of carotene causes carotenemia, not vitamin A toxicity.
Carotenemia is usually asymptomatic but may lead to carotenodermia, in which the skin becomes yellow. When taken as a supplement, β-carotene has been associated with increased cancer risk; risk does not appear to increase when carotenoids are consumed in fruits and vegetables.
Eating carrots and vegetables cannot do any harm to your baby.
