1. Beef is rich in sarcosine. The content of sarcosine in beef is higher than that in 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. The greater the demand for vitamin protein in beef, the more vitamin B6 should be added in the diet. Beef contains enough vitamin B6, which can help you enhance your immunity, promote the metabolism and synthesis of protein, and thus contribute to the recovery of your body after intense training. The nutritional value of beef is second only to rabbit meat, and it is also suitable for fat people. Every 1g of beef contains more than 2g 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., which are placed in the freezer, are often cooked with hot water immediately after thawing. In fact, this practice is unscientific. 3. Beef contains carnitine. The content of carnitine and sarcosine in chicken and fish is very low, but the content of beef is very high. Carnitine is mainly used to support fat metabolism and produce branched-chain amino acids, which plays an important role in bodybuilders' muscle growth. 4. Beef contains potassium and protein potassium, which are relatively lacking minerals in most athletes' diets. Low level of potassium will inhibit the synthesis of protein and the production of growth hormone, thus affecting muscle growth. 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. The fat content in beef is very low, but it is rich in conjugated linoleic acid. These potential antioxidants can effectively combat tissue damage caused by weightlifting and other sports. In addition, linoleic acid can also be used as an antioxidant to maintain muscle mass. 6. Beef contains zinc, magnesium and zinc, which is another antioxidant that helps to synthesize protein and promote muscle growth. Zinc works with glutamate and vitamin B6*** to enhance the immune system. Magnesium supports the synthesis of protein, enhances muscle strength and, more importantly, improves the efficiency of insulin anabolism. 7. Beef contains iron, which is an essential mineral for hematopoiesis. In contrast to the poor iron content in chicken, fish and turkey, beef is rich in iron. 8. Beef contains propylamine acid. The function of propylamine acid is to produce sugar from protein in diet. If you don't take enough carbohydrates, alanine can supply the energy needed by muscles to alleviate the deficiency, so that you can continue training. The biggest advantage of this amino acid is that it can liberate muscles from the burden of supplying energy. 9. Beef contains vitamin B12, which is very important for cell production, and the function of red blood cells is to bring oxygen to muscle tissue. Vitamin B12 can promote the metabolism of branched-chain amino acids, thus supplying the body with the energy needed for high-intensity training. 1. Diversification of beef consumption If you eat it day after day for weeks or even months, the chicken breast looks boring. Beef, on the other hand, has different tastes and tastes, such as hind leg meat, flank meat, upper loin meat and thin meat slices, which are really different from the dull chicken breast.
