Beef is rich in protein, and its amino acid composition is closer to human needs than pork, which can improve human disease resistance. It is especially suitable for people who are growing and recuperating after surgery and disease to supplement blood loss and repair tissues. Eating beef in cold winter has the function of warming the stomach and is a good tonic in cold winter. Chinese medicine believes that beef has the functions of invigorating the middle energizer, invigorating the spleen and stomach, strengthening bones and muscles, resolving phlegm and calming wind, quenching thirst and promoting fluid production. Suitable for people with stagnation of qi, shortness of breath, weakness of muscles and bones, anemia and yellow complexion.

The nutritional value of eating beef is:

1. Beef is rich in sarcosine.

The content of sarcosine in beef is higher than any other food, which makes it particularly effective for muscle growth and strength enhancement. In the first few seconds of training, sarcosine is the source of muscle fuel, which can effectively supplement adenosine triphosphate, thus making the training last longer.

2. Beef contains vitamin B6.

The greater the demand for protein, the more vitamin B6 should be added to the diet. Beef contains enough vitamin B6, which can help you enhance your immunity and promote the metabolism and synthesis of protein, thus helping your body recover after intense training. The nutritional value of beef is second only to rabbit meat, and it is also suitable for fat people. Every 100g of beef contains more than 20g of protein, and beef protein contains more essential amino acids and lower fat and cholesterol. Therefore, it is especially suitable for obese people and patients with hypertension, arteriosclerosis, coronary heart disease and diabetes. Frozen fish, livestock meat, poultry meat, etc. Put it in the refrigerator and usually cook it in hot water immediately after thawing. In fact, this practice is unscientific.

3. Beef contains carnitine

Carnitine and sarcosine in chicken and fish are low, but beef is high. Carnitine is mainly used to support fat metabolism and produce branched-chain amino acids, which plays an important role in muscle growth of bodybuilders.

Beef contains potassium and protein.

Potassium is a mineral that most athletes lack in their diet. Low level of potassium can inhibit the synthesis of protein and the production of growth hormone, thus affecting the growth of muscle. Beef is rich in protein: 4 ounces of lean tenderloin can produce 22 grams of first-class protein.

5. Beef is a low-fat source of linoleic acid.

Beef is low in fat, but rich in conjugated linoleic acid. These potential antioxidants can effectively resist tissue damage caused by weightlifting and other sports. In addition, linoleic acid can also be used as an antioxidant to maintain muscle mass.
