The nutritional value of pig liver is 1? It is rich in iron, especially "heme iron", which is higher than the iron content in meat, and it is acceptable and has high absorption and utilization rate. It can help women and babies to supplement iron and prevent iron deficiency anemia.
2、? Rich in vitamin A, eating pig liver can improve vision. Because it contains vitamin A, it can effectively prevent and treat eye diseases such as night blindness, dry eye and keratomalacia.
3、? It also contains other vitamins and trace elements, such as vitamin D, vitamin B2, vitamin B 12, zinc and copper. This is the most nutritious food.
How to choose pig liver? Choose bright red, smooth surface, elastic when pressed, and no odor. If there is congestion, it is abnormal swelling, hardening or even bile or congestion. It can't eat. Maybe it's liver disease.
Pig liver is suitable for men, women and children, and there are no unfavorable people. Of course, the cholesterol in pig liver is relatively high, and people with high cholesterol eat less.
The timidity of pig liver mainly comes from the popular saying that the liver will be poisoned, because the liver is a detoxification organ and may accumulate some toxic substances, but this is because the pig itself is sick or the feed is polluted. As long as you buy it regularly, it will generally not be poisoned.
Therefore, it is recommended that healthy people who are not iron deficient or vitamin A deficient can eat it once or twice a month.
Normal liver is the base camp for animals to store nutrients, and it is also a big factory for synthesizing nutrients. Whether it's good or not depends on people.
Benefit 1: fully supplement vitamins and vitamins!
Fat-free healthy liver, whether chicken liver, duck liver, pig liver, sheep liver or even human liver, has a fat content of less than 5%, but it is as high as 20% in protein. It contains all 13 vitamins needed by human body, especially vitamin AD, and also contains many health-care components such as lecithin, betaine, choline and carnitine.
For people with dry skin and eyes, the liver is the best source of vitamin A supplementation. Compared with carrots, the effect is much slower. Infants and young children can't quickly convert carotene into vitamin A, which is prone to vitamin D deficiency. Therefore, nutritionists often suggest that liver mud made of healthy and safe liver should be included in infant complementary food.
Benefit 2: iron supplementation has the best effect, no one!
The liver is rich in trace elements, especially heme iron, and its absorption and utilization rate is much higher than that in plant foods (compared with iron in the liver, any fungus, kelp and black sesame are weak! )。 Therefore, nutritionists also suggest that children, young women and pregnant women with iron deficiency anemia often eat animal liver.
Benefit 3: high protein and low fat!
Healthy liver is high in protein and low in fat. The protein content of liver is above 20%, which is higher than that of lean pork, but the fat content is lower than 5%, so it won't get fat after eating, which is probably unexpected for many people. Although rich in cholesterol, high cholesterol and high fat are two different things.
