Many people will stay away from animal viscera. In fact, the internal organs of cattle and other animals have little-known nutritional value, and proper consumption is beneficial to health. The British "Daily Mail" recently published an article "Nutrition and Edible Methods of Beef offal".

1, beef liver. The iron content of beef liver is higher than that of beef. Bovine liver or chicken liver 1 serving (150 ~ 200g) can meet 75% of the recommended daily iron for women. Another advantage of eating beef liver is to supplement copper, which is very important for brain development, strengthening bones and enhancing immunity. People with weak constitution and the elderly can often eat beef liver. Roy kleven, a British nutrition expert, suggested that the liver can be fried with vegetables such as onions.

2. Cow kidney. The protein content of 1 bovine kidney (kidney) is the same as that of steak, and it can also meet the daily iron demand of women. The fat content of bovine kidney is only 4%, which is lower than that of steak. It is also one of the best food sources of selenium, which helps to protect thyroid function and prevent human tissue damage. Beef kidney can be eaten at will, usually fried, roasted and roasted.

3. Niu Xin. The protein content of bovine heart is higher than that of bovine kidney. Cattle hearts are all lean meat and rich in B vitamins. One serving of beef heart can meet the iron requirement of men (half that of women) and the zinc requirement of13. Beef heart is suitable for stewing, frying and stewing.

4, tripe. Tripe is a good diet food because its fat and energy are relatively low. 1 tripe contains only 49 calories. The calcium content of tripe is very high, with 52 mg of calcium in100g. Fried tripe is the best.

5, beef tongue. Eating 1 serving of beef tongue can meet 1/3 of women's daily iron intake. The contents of vitamin B 12 and vitamin C in beef tongue are 7 times and 6 times that of ham, respectively. Beef tongue is suitable for marinating, sauce, frying, stewing and frying.

6, oxtail. 1 A small portion of oxtail contains 15 mg of zinc, which can almost meet the zinc demand of human body for one day. Studies have found that zinc is vital to the immune system, and it can also shorten the cold period and relieve cold symptoms. Oxtail soup is equivalent to chicken soup in relieving colds.

Last but not least, pregnant women should eat less beef offal. Because it contains a lot of vitamin A, too much intake will easily increase the birth defects of newborns.
