Nutritional value of beef

1, beef is rich in sarcosine. The content of sarcosine in beef is higher than any other food, which is especially 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 and make the training last longer.

2. Beef contains vitamin B6. The greater the demand for protein, the more vitamin B6 is 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.

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. Beef is rich in protein: 4 ounces of lean tenderloin produces 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. Potential antioxidants can effectively combat tissue damage caused by weight lifting and other sports. In addition, linoleic acid can also be used as an antioxidant to maintain muscle mass.

6. Beef contains iron. Iron is an essential mineral for hematopoiesis. Compared with chicken, fish and turkey, beef is rich in iron.
