Vitamin A in food

Vitamin A can be found in animal foods (liver, milk, eggs, fish) and plant foods (green and yellow vegetables, fruits). Green and yellow vegetables, which are particularly high in beta-carotene, are converted to retinol in the intestines and liver, where it is absorbed by the body.
Animal foods: found in liver, milk, and egg yolks.
Plant foods: found in carrots, spinach, peanuts, sweet potatoes, etc. in the form of carotene, which is converted into vitamin A, which the body needs.
