Beef has a high protein content, protein is the material basis of all life, is an important part of the body's cells, is the main raw material for the renewal and repair of human tissue. Every tissue of the human body: hair, skin, muscle, bone, internal organs, brain, blood, nerves, endocrine, etc. are composed of protein, so that the diet creates the person itself. Protein is very important for human growth and development.

Beef Food Value
1. Beef is rich in creatine
Beef contains more creatine 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 and making training 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 to help you strengthen your immune system and boost protein metabolism and synthesis, which in turn helps your body recover after intense training.
3. Beef contains carnitine
Chicken and fish are low in carnitine and sarcosine, while beef is 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 lacking in an athlete's diet. Low levels of potassium inhibit protein synthesis and the production of growth hormone, which affects 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 exercise, such as weight lifting. In addition, linoleic acid acts as an antioxidant to maintain muscle mass.
6. Beef contains zinc and magnesium
Zinc is an 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, builds muscle strength, and more importantly, increases the efficiency of insulin anabolism.
7. Beef contains iron
Iron, blood mineral. Chicken, fish, turkey in contrast to the poor iron content, beef is rich in iron.
8. Beef contains propionic acid
Propionic acid works by : producing sugar from dietary protein. If you're not getting enough carbohydrates, proanthranilic acid can provide your muscles with the energy they need to relieve the deficit and allow you to continue training. The great thing about this amino acid is that it frees the muscles from the heavy burden of supplying energy.
9. Beef contains vitamin B12
Vitamin B12 is essential for the production of cells, the role of red blood cells: to bring oxygen to muscle tissue. Vitamin B12, which boosts the metabolism of branched-chain amino acids, provides the body with the energy it needs to perform high-intensity training.
10. Diversify your beef consumption
Consuming chicken breasts day in and day out for weeks or even months at a time can be tiresome. Beef is different, with hind leg, flank, upper loin and thinly sliced meat varying in flavor and texture, and the monotonous chicken breast is really not comparable.
