1, beef is rich in creatine Beef contains more creatine than any other food, which makes it particularly effective for muscle growth and strength. In the first few seconds of training, creatine is the source of muscle fuel, which can effectively replenish adenosine triphosphate, so that training can last longer.　　2, beef contains vitamin The greater the protein demand, the more vitamin B6 should be added to the diet. Beef contains enough vitamin B6, can help you strengthen immunity, promote protein metabolism and synthesis, thus helping the body recover after intense training. Beef is second only to rabbit in terms of nutritional value and is also a suitable meat for fat people. Every 100 grams of beef contains more than 20 grams of protein, beef protein contains more essential amino acids, and contains fat and cholesterol is low, therefore, especially suitable for fat people and hypertension, vascular sclerosis, coronary heart disease and diabetes mellitus patients moderate consumption. Put in the refrigerator freezer frozen fish, livestock, poultry and other meat, when used, some people often use hot water to thaw immediately after cooking, in fact, this practice is not scientific.　　3, beef carnitine chicken, fish carnitine and sarcosine content is very low, beef is very high. Carnitine is mainly used to support the metabolism of fat, producing branched-chain amino acids, an amino acid that plays an important role in muscle growth for bodybuilders.　　4, Beef Contains Potassium and Protein Potassium is a mineral that is relatively lacking in most athletes' diets. Low levels of potassium inhibit protein synthesis and the production of growth hormone, thus affecting muscle growth. Beef is rich in protein: 4 ounces of lean tenderloin produces 22 grams of first-rate protein.5. Beef is a low-fat source of linoleic acid Beef is very low in fat but rich in bound linoleic acid, and these potential antioxidants can be effective in combating tissue damage caused by weightlifting and other sports. In addition, linoleic acid acts as an antioxidant to maintain muscle mass.　6, Beef contains zinc and magnesium Zinc is another antioxidant that helps synthesize protein and promotes muscle growth. Zinc works with glutamate and vitamin B6*** to boost the immune system. Magnesium supports protein synthesis, muscle strength, and more importantly, can improve the efficiency of insulin anabolism.　　7, beef containing iron Iron is an essential mineral for hematopoiesis. With chicken, fish, turkey in the iron content of the poor contrast, beef is rich in iron.　　8, beef contains propionic acid The role of propionic acid is to produce sugar from dietary protein. If your intake of carbohydrates is insufficient, propionic acid is able to supply your muscles with the energy they need to alleviate the deficiency, thus allowing you to continue training. The biggest benefit of this amino acid is that it can free the muscles from the heavy burden of supplying energy.　　9, beef contains vitamin Vitamin B12 is essential for the production of cells, and the role 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.　　10, beef consumption diversity If consumed day in and day out for weeks or even months on end, chicken breasts seem tiresome. Beef is different, hind leg meat, flank meat, upper loin meat and fine meat slices in the taste and texture are different, and monotonous chicken breast is indeed not the same. Raw beef has a lot of bacteria and parasites that can make you sick if not killed. It is recommended to eat it cooked.
