吃牛肉有哪些好處？

2021 is the Year of the Ox (Xin Chou year). The ox is associated with diligence and simplicity, and beef is an important ingredient in Chinese culinary culture, second only to pork. However, the nutritional value and health effects of beef often confuse the public.

Beef is rich in high-quality protein, with an amino acid composition that better meets human needs, and also contains abundant minerals, such as...鈣It contains iron, zinc, and other minerals. Many people, especially pregnant women, cancer patients, or those recovering from surgery, often hesitate about whether or not to consume beef. Some superstitious beliefs circulate, such as that pregnant women eating beef will darken the baby's skin, or that eating beef will stimulate tumors in cancer patients; these lack scientific basis. As the *Di Zi Gui* (Standards for Being a Good Student and Child) states: "Do not be picky about food. Eat in moderation, and do not overeat."

Pregnant women can consume beef in moderation during pregnancy, as it is beneficial for both the mother and the fetus. Pregnant women require 1.5 times the amount of iron and zinc as the average person, and beef is rich in these nutrients, which can boost immunity.folateThis helps prevent birth defects in infants. Nutritionists recommend that pregnant women eat lean beef 3-4 times a week, 60-100 grams each time, to prevent iron-deficiency anemia.

Zinc from beef is more easily absorbed by the human body than zinc from plant sources. Therefore, consuming beef in moderation will not only not have adverse effects on the fetus, but can also supplement the nutrients needed for fetal development.

Cancer patients need to consume sufficient protein during treatment to help repair cells. While some breast cancer patients or those recovering may avoid beef for fear of stimulating tumors, in fact, cancer patients require more protein daily than the average adult. Meat is rich in protein, and it is recommended to eat more high-quality meats, including beef. After completing treatment, red meat intake can be reduced, but it is not necessary to completely eliminate it.

However, excessive consumption of red meat (beef, pork, lamb) increases fat intake and raises the risk of colon and breast cancer because fat cells contain high levels of estrogen. Other meats, such as goose and duck, are also quite high in fat (approximately 23 grams per 100 grams). In contrast, chicken and lean meat are lower in fat (approximately 9-13 grams per 100 grams), and fish and seafood are even lower in fat, primarily consisting of unsaturated fats.

The International Agency for Research on Cancer (IARC) recommends that red meat intake should be less than 500 grams per week. The Hong Kong Cancer Society's "Diet and Cancer" also suggests that daily red meat intake should not exceed 3 ounces, and should be combined with chicken, fish, seafood, eggs, and soy products to help reduce the risk of cancer.
