Which vegetables and fruits are high in vitamin A can also be 5

There are two types of foods rich in vitamin A. One is provitamin A, a variety of carotene, which is found in plant foods, such as green leafy vegetables, yellow vegetables, and fruits.

Fruits, rich in spinach, alfalfa, pea seedlings, sweet potatoes, carrots, green peppers, pumpkins, etc.; The other category is vitamin A, which comes from animal foods, which can be directly used by the human body, mainly in animal liver, milk and dairy products (non-skimmed milk) and poultry eggs. According to the Food Analysis Table, the richest content of vitamin A per serving (100 grams) on average (about 12,000 units) is in leafy greens, such as kraft, kale, spinach and other green vegetables. Even a serving of sword beans, broccoli, carrots, pumpkin, apricots, sweet potatoes, or yams provides 5,000 units of vitamin A, which is exactly what an adult needs in a day.

A serving of tomatoes, peas, celery, lettuce, and asparagus also contains close to 2,000 units on average. With the exception of apricots, most yellow fruits contain less than 400 units of vitamin A in a serving. This vitamin is missing in vegetables that have lost their original color or have never turned green.

As can be seen from this food analysis table, animal liver is extremely rich in vitamin A, and animal kidneys and offal are also very high. Vitamin A cannot be stored in the muscles, and it is lacking in grilled, fried meats and steaks. Eggs and milk fat contain vitamin A, the amount of which depends on the food the animal eats.

The amount of vitamin A per litre of whole milk is 500,7000 units, but the average is 2,000 units. When milk is homogenized, most of the vitamin A is destroyed by oxygen, but so far, humans have not found a solution to this problem. The milk produced by cows after being fed hay is winter butter, which may contain only 2,000 units of vitamin A per 450 grams of winter butter, compared to an average of 12,000 units per 450 grams of summer butter.

The amount of vitamin A added in the butter substitute is usually 12,000 units per 450 grams. Cod liver oil is the richest source of vitamin A commercially**. The amount of vitamin A in an animal's liver depends on the food ingested and the age of the animal.

In addition to the liver of polar bears, the liver oil of a centenarian python in the London Zoo has been confirmed to be the richest in vitamin A, and the vitamin A content in halibut liver oil is richer than that in cod liver oil, because halibut is older than cod when it is on the market, and the cod sold in the market is generally still in a relatively small stage, so halibut has more years to eat the green seaweed in the sea. For the same reason, the livers of adult cows and sheep contain much more vitamin A than the livers of calves and lambs.

1. Carrots.

Carrots contain a large amount of carotene, the molecular structure of this carotene is equivalent to 2 molecules of vitamin A, after entering the body, in the liver and small intestine mucosa through the action of enzymes, 50% of which become vitamin A, has the effect of tonifying the liver and brightening the purpose, can be ** night blindness.

2. Kiwi.

There are many fruits and vegetables containing vitamin A, common fruits are cantaloupe, grapefruit, papaya, etc., and common vegetables are green peppers, tomatoes, sweet potatoes, etc., and the vitamin A content in these fruits and vegetables is relatively high.

These fruits are rich in nutrients, in addition to containing more vitamin A, they also contain vitamin C, dietary fiber, amino acids, etc., and eating them in moderation can also help supplement nutrition. If vitamin A deficiency is not severe and there are no obvious uncomfortable symptoms, it can be supplemented by eating fruits and vegetables.

However, if the vitamin A deficiency is more severe, and there are obvious symptoms that are not symptoms, it needs to be carried out under the guidance of a doctor**. Common foods containing vitamin A include animal liver, milk, eggs and cod liver oil. Fruits and vegetables do not directly contain vitamin A, but they do contain carotene, which can be converted into vitamin A by metabolism in the body, so it is also called provitamin A.
