come, let’s learn the most basic diet nutrition knowledge: the importance of protein food. Reading requires patience – protein food refers to fish and shrimp, meat, eggs, milk and soy products. The common feature of these foods is that they contain more high-quality protein, which means that after being digested and absorbed into the human body, they can be well utilized to one enemy and two. In contrast, the protein content in grains, vegetables and fruits is either low or not good enough.

and

proteins constitute skin, bone, muscle and all organs.

and

proteins are the most important nutrients needed by human body. Our whole body, from heel to hair, including skin, bones, muscles and all organs, is mainly made of protein. In childhood, the skin, bones, muscles and organs of the body continue to grow and develop, which requires a large amount of protein intake; in adulthood, although the growth and development stops, the body protein is constantly updated and consumed (metabolism), so it also needs to be supplemented from food; after old age, the body gradually loses the white matter, organ atrophy, skeletal muscle decreases, height becomes shorter, and dietary supplement protein is needed Especially important; pregnant women and lactating mothers in order to give birth to or nurture new life (mainly composed of protein), must also eat a lot of protein; in the recovery period of many diseases, in order to repair damaged tissues or organs, it is necessary to eat more protein. Therefore, whenever and wherever, keep in mind that protein is the key to maintaining good health.

if the diet does not have sufficient protein, the fetus is difficult to develop normally; the children can not grow normally; the adult’s physique, physical strength and immunity are low, and the energy is insufficient; the aging of the elderly is accelerated, and the recovery of the patients is delayed, and it is difficult to recover their vitality. In a word, protein constitutes our body. To love our body, we must “love” protein.

and

proteins are the basis of all life activities.

and

proteins not only constitute our body, but also participate in various life activities in the form of hormones, enzymes, antibodies, complement, hemoglobin, apolipoprotein, immunoglobulin and so on. The names of these living substances may be strange, but they bring functions that we use every day, such as feeding, excretion, metabolism, exercise, blood circulation, respiration, immunity, thinking, emotion, desire, gene replication At the end of the day, these functions are performed by proteins, and a world without them is unthinkable.

in vivo, these crucial proteins are synthesized by cells, but their raw materials must be provided by food, especially by the protein in food. The protein in the food is digested and decomposed into amino acids in the intestine, then absorbed into the blood, and then transported to the corresponding tissues or organs by the blood. In the cells of these tissues or organs, amino acids re synthesize various human proteins through complex biochemical processes, and play roles in their respective positions. At the same time, the body’s original protein will be gradually decomposed into amino acids, or reuse, or degradation excretion, complete metabolism.

and

proteins need to be replenished frequently. The amino acids and proteins in

and

that have completed their mission or are no longer used will be degraded into other substances and excreted with urine in the form of urea and creatinine. Even if you eat a lot of protein one day, they can’t be stored in the body. They will be quickly metabolized and excreted from the urine. This is completely different from fat and sugar. If you eat a lot of fat and sugar one day, they will be stored in the adipose tissue under your belly or other parts of your body. Unless you exercise hard, they will be stored there for a long time. The protein ingested by

and

cannot be stored in the body. Therefore, the better mode of protein supplement is to take in some protein (about 60-100g) every day to maintain the metabolic needs. Moreover, if conditions permit, it is best to eat some protein (about 20-30 grams) per meal. Only those with severe renal impairment, who often need a low protein diet, should consult their doctor. In addition to high-quality protein, another important reason why

and

take protein food as the core of nutritional diet is that these protein foods are also rich in other nutrients. For example, fish and eggs are important sources of iron, zinc, selenium, chromium and other trace elements, not only the content is relatively large, but also easy to digest and absorb. Fish and eggs are also important sources of phospholipids, vitamin A, vitamin B12, vitamin B1, vitamin B2 and vitamin B6. Fish are also important sources of vitamin D, DHA, calcium and potassium. Among them, vitamin D and vitamin B12 hardly exist in plant food. Milk is also a good source of calcium, zinc, vitamin A and vitamin B2. Soybean and its products are also important sources of polyunsaturated fatty acids, calcium, vitamin B1 and vitamin B6. Therefore, as long as we grasp the core of protein food and eat a variety of protein food well, we can solve most of the nutrient needs, not only protein, but also a variety of vitamins and minerals.

and

are particularly important. When protein foods such as fish, meat, eggs, milk and soybean products are eaten together with grains or vegetables, their proteins complement each other and learn from each other, thus increasing the nutritional value of the whole protein; meat, fish and shrimp also promote the absorption of iron, carotene and other nutrients in grains or vegetables, and improve the nutritional quality of the whole meal.
