The food value of beef
1, beef is rich in carnosine
Beef contains more carnosine than any other food, and it is particularly effective in growing muscles and building strength. In the first few seconds of training, creatine is the source of muscle fuel, effectively replenishing adenosine triphosphate so that training can last longer.
2, beef contains vitamin B6
The greater the protein requirement, the more vitamin B6 is added to the diet. Beef contains enough vitamin B6, can help you strengthen immunity, promote protein metabolism and synthesis, thus helping the body to recover after intense training.
3, beef contains carnitine
Chicken and fish are low in carnitine and sarcosine, but beef is high. Carnitine is mainly used to support fat metabolism, 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 absent from an athlete's diet. Low levels of potassium inhibit protein synthesis and the production of growth hormone, affecting muscle growth. Beef is rich in protein: 4 ounces of lean tenderloin yields 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, a potential antioxidant that can be effective in combating tissue damage caused by weight lifting and other exercise. In addition, linoleic acid acts as an antioxidant to maintain muscle mass.
