Does oral amino acid have tonic effect?

Compared with lipids, protein has a very good nutritional image People often associate protein with strong muscles and healthy body, and think that athletes need to eat meat to achieve good results It can't be denied that protein is indeed a very important nutrient, but it can only bring health benefits under the appropriate intake Proteins are made of amino acids Amino acids contain a nitrogen atom, which is a major feature of amino acids, because neither fat nor carbohydrates contain nitrogen 　　   All kinds of nitrogen containing substances in our body are mostly synthesized by amino acids in proteins There are 20 kinds of amino acids used to make up proteins in the body Among them, there are 8 kinds of amino acids that we call essential amino acids, because we have to get these 8 kinds of amino acids through food intake That is to say, my body can't synthesize these amino acids, or the synthesis speed of these amino acids is very slow, so that the synthesized amino acids can't satisfy us Body The eight essential amino acids are isoleucine, threonine, tryptophan, methionine, phenylalanine, leucine, valine, lysine and phenylalanine 　　   There are two other amino acids that our bodies can synthesize, but they must be converted from some essential amino acids For example, cysteine (which must be synthesized by methionine) and tyrosine (which must be synthesized by phenylalanine) are semi essential amino acids In other words, if we can get enough cysteine and tyrosine from food, the body will not need to consume more methionine and phenylalanine Of course, it should also be noted that the physical development of infants is not mature enough for adults to synthesize histidine, so in addition to the above 8 essential amino acids for infants, histidine is also an essential amino acid for infants 　　   In addition to these amino acids mentioned above, other amino acids that are not necessary do not mean that they do not need to be taken from food at all Although human body can synthesize these amino acids, the nitrogen element in synthetic materials also needs to be taken from food protein In other words, the human body's need for protein has two meanings: one is that one kind of essential amino acid should not be less and the proportion should be appropriate; the other is that the total protein quality should be enough to ensure the synthesis of non essential amino acid and other important nitrogen-containing substances Amino acids are so important, so does taking amino acids have tonic effect? There are all kinds of amino acid supplements on the market Some people think that buying these products and taking extra amino acids orally can increase nutrition and reduce the "work load" of digesting protein In fact, every kind of food contains essential amino acids for human body No matter it is rice noodles or egg milk, as long as there is protein in the food, it can provide amino acids The healthy human body does not need to digest the protein into small peptide or amino acid in advance The elephant base acid obtained from a natural food such as an egg is much more than an amino acid supplement When the human body digests protein, it can choose and regulate the absorption of amino acids according to the needs of the body If it takes amino acid supplements, it will rapidly increase the type and quantity of amino acids in the body, which may not only lead to high osmotic pressure of body fluids, but also may cause disorder of amino acid balance Only those who are unable to digest and absorb normally due to some diseases, such as serious diseases in the digestive tract, gastrointestinal resection, pancreatic diseases and other patients, need to take amino acid supplements.
