Sources can be cows, bulls and heifers. The muscle part of cattle can be cut into steak, beef pieces or beef bones, and can also be mixed with other meats to make sausages or blood sausages. Other edible parts include ox tail, ox liver, ox tongue, ox louver, ox pancreas, ox thymus, ox heart, ox brain, ox kidney and ox whip.

The meat quality of steer and heifer is similar, but steer has less fat. Old cows and bulls have thick and hard meat, which is often used to make ground beef. Beef cattle generally need to be fattened and fed with grains, dietary fiber, protein, vitamins and minerals.

Expand the nutritional value of beef. It contains a lot of sarcosine and carnitine.

Beef has the highest sarcosine content in all foods, which can enhance strength and promote muscle growth, and at the same time, it can supplement adenosine triphosphate for the body, making people's training more lasting. Beef contains a lot of carnitine, which can support the most basic metabolism of fat and thus produce amino acids, which is suitable for people who want to grow muscles.

Second, it is rich in vitamins.

When the body's demand for protein increases, we should supplement the body with foods rich in vitamin b6, which can strengthen the immune system, promote the synthesis of protein and accelerate metabolism. Suitable for people who have just finished training, and can make their physical strength recover quickly. Beef protein contains essential amino acids, which is a kind of meat with low fat and cholesterol.

Third, it contains a lot of protein, potassium and linoleic acid.

When the human body is deficient in potassium, it will inhibit the synthesis of protein and affect the production of growth hormone, which is not conducive to muscle growth. It happens that beef is rich in protein and element A, which can meet the needs of the body. Beef contains special linoleic acid, which can remove free radicals harmful to the body. It is an antioxidant and can maintain muscle mass.

Fourth, it is rich in iron, zinc and magnesium.

Zinc participates in the synthesis of protein, which can promote muscle growth. Zinc, vitamin b6 and glutamate together can strengthen the immune system. Magnesium can enhance muscle strength and improve insulin anabolic function. Iron participates in the synthesis of hemoglobin and is an essential mineral in hematopoietic system.

Fifth, it contains a lot of alanine and vitamins.

Alanine can produce sugar from protein. When carbohydrate intake is insufficient, alanine plays a vital role and can provide energy for muscles. In addition, beef is also rich in vitamin b 12, which can promote the metabolism of branched-chain amino acids and provide energy for high-intensity training.
