It is impossible for the human body to get all the nutrients it needs when it absorbs the nutrients of various foods, but it is the most direct and complete intake from beef. Moreover, beef is rich in nutrition. More than half of the 22 kinds of amino acids that the human body needs every day can be made by the human body, but 8 kinds of amino acids that the human body cannot make are called essential amino acids and have to be taken in food.
Beef food contains these eight essential amino acids, which are absorbed by 100%, and the nutrition of any animal or plant is inferior to that of beef. So eating a piece of beef is worth a day's nutrition.
The lean meat of beef is rich in excellent nutrients such as high-quality protein, iron and vitamin B group.
Protein is an indispensable nutrient for maintaining human health. Protein, sugar and fat are the three essential nutrients for human body, and they are also the most important nutrients for maintaining life. Our muscles, skin, organs, bones, blood vessels, hair and nails are all made of them, and they are also raw materials for making blood, hormones, oxygen, neurotransmitters and immune substances.
Beef contains balanced essential amino acids, and protein contained in food will be decomposed and utilized by small units of amino acids in the body, while essential amino acids cannot be synthesized from the body and need to be supplemented from food.
Essential amino acids-8 for adults and 2 for children 10. Another feature of beef is that it contains balanced amino acids. Developing children have a strong body; The digestive function of the elderly is degraded, and the absorption ability is reduced. , all need to bring more.
Beef is rich in iron and is easily absorbed by human body. Oxygen and energy are transported to all parts of the body through hemoglobin in red blood cells. And its ingredients can't be iron-deficient. There are two kinds of iron in food. Women who often lose weight are prone to anemia. For those who want to stay healthy and energetic, preventing anemia is very important.
Symptoms caused by iron deficiency: anemia, poor blood gas, cold hands and feet, easily broken nails and split hair. Women lose iron 15-30mg every month due to menstruation, so the demand for iron is 20% more than that of men. In addition, in order to make pregnant baby's blood, the iron needed in early pregnancy is 10mg, and the iron needed in mid-pregnancy and lactation is twice that of men, that is, 20mg. Regular consumption of easily absorbed and low-calorie beef can greatly increase the absorption of iron. Therefore, I suggest that you might as well consider this kind of food in your food.
