1, yellow fruits and vegetables and green leafy vegetables: rich in beta-carotene The human body will convert beta-carotene into vitamin A as needed after ingesting beta-carotene, which can avoid poisoning caused by excessive intake of vitamin A. Therefore, beta-carotene is a safe source of vitamin A for human consumption. Most orange fruits and vegetables contain more beta-carotene, including carrots, pumpkin, loquat, apricot, sweet potato, papaya, mango, tomato, etc.; green vegetables such as spinach, lettuce, broccoli, leek, rape, and capers also contain more beta-carotene. However, since carotene is a fat-soluble substance, it should be fried in oil or stewed with meat before consumption to facilitate absorption, so it is actually useless for us to eat raw carrots to absorb beta-carotene. 2, animal liver: a natural source of vitamin A The chemical name of vitamin A is retinol, also known as the anti-dry eye vitamin. The lack of vitamin A in the human body affects the ability to adapt to darkness, such as stunting in children, dry eye disease, night blindness, etc. Proper consumption of foods rich in vitamin A is good for eye protection. Natural vitamin A is only found in animal foods, such as animal liver, eggs, cream and cod liver oil, especially animal liver is extremely rich in vitamin A. However, in view of the high chance of contamination of animal liver in recent years, it is also not recommended to give children frequent consumption of liver, Lina Guo believes that chicken liver can be used to replace pig liver. In addition, the use of cod liver oil must look at the dose of the product, the dose of different brands of products vary greatly, should be based on the need to choose, do not blindly take cod liver oil to supplement vitamin A.
