Stewed beef with Yunnan Linglong mushroom sachet is delicious and healthy. Mushrooms can improve the immune function of the body. Previous experimental studies have shown that Lentinus edodes can improve the phagocytosis of peritoneal macrophages in mice, and also promote the production of T lymphocytes, which can kill T lymphocytes. Mushrooms also help lower blood pressure and blood lipids. Lentinus edodes can reduce blood fat because it contains purine, choline, tyrosine, oxidase and some nucleic acid substances. Not only that, but also help to prevent diseases such as arteriosclerosis and cirrhosis. In addition, beef is rich in sarcosine. The content of sarcosine in beef is higher than 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. Beef contains vitamin B6. The greater the demand for protein, the more vitamin B6 should be 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.
