1, beef is our second largest meat food, next to pork. Beef has a high protein content and a low fat content, so it tastes delicious and is loved by people, and enjoys the reputation of "the favorite among the meat". 2. Dried beef is dried meat marinated with beef; Dried beef contains a variety of minerals and amino acids needed by human body, which not only maintains the chewy flavor of beef, but also does not deteriorate for a long time. 3. Dried beef has a good dietotherapy effect. Beef has the effects of invigorating the middle warmer, invigorating qi, nourishing the spleen and stomach, strengthening bones and muscles, resolving phlegm, calming wind, quenching thirst and stopping saliva, and is suitable for people with hidden middle warmer, short breath, weak body, weak bones and muscles, anemia and long illness, and yellow and dizzy face. 4. Beef jerky 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. 5. Beef jerky contains enough vitamin b6, which can help you enhance your immunity and promote the metabolism and synthesis of protein, thus contributing to the recovery of your body after intense training. 6. Beef jerky 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. 7. Beef jerky contains potassium and protein. Potassium is a mineral that most people lack in their diet. 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. 8. Beef jerky 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 activities. In addition, linoleic acid can also be used as an antioxidant to maintain muscle mass. 9. Beef jerky contains zinc and magnesium. Zinc 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. 10, beef jerky contains iron. Iron is an essential mineral for hematopoiesis. In contrast to the poor iron content in chicken, fish and turkey, beef is rich in iron. 1 1, beef jerky contains alanine. The function of alanine 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. 12, beef jerky contains vitamin b 12. Vitamin b 12 is very important for the production of cells, and the function of red blood cells is to bring oxygen to muscle tissue. Vitamin b 12 can promote the metabolism of branched-chain amino acids, thus supplying the body with energy needed for training. 13, beef jerky is sweet, flat, spleen and stomach. It contains abundant nutrients such as sarcosine, vitamin b6, vitamin b 12, alanine, carnitine, protein, linoleic acid, zinc, magnesium, potassium, iron, calcium, etc. These nutrients have the functions of enhancing immunity and promoting metabolism, and especially have obvious curative effects on physical recovery and physical fitness. Moreover, Dr. Caroline Ray of the University of Sydney found that beef can improve people's intelligence, especially for occasions where students need to "temporarily improve their intelligence".
