Plant protein powder will add various nutrients to make up for the low absorption rate of plant protein. But not suitable for young men and bodybuilders.
There are several kinds of animal proteins, one is pure whey protein, which is made from milk. No other substances are added.
One is mixed protein, mainly whey protein, and there are different amounts of egg protein and casein, considering the extension of absorption time.
Whole protein powder is a kind of purified food, which has no side effects on the body. Of course, if you eat it as a meal, you may get gout because of protein's excessive intake.
As an important nutrient in human body, protein is the material basis of all life, and it will be digested and decomposed into several indispensable amino acids in human gastrointestinal tract. These amino acids are sent to human cells through human blood and used to synthesize various tissues, hormones, enzymes, immunoglobulins, antibodies and other important physiologically active substances. The improvement of energy and immunity in our daily activities depends on the role of protein. If the human body lacks protein, it will bring great harm to health. But for us normal people, as long as we adhere to a normal diet, the lack of protein generally does not exist, so there is no need to supplement protein with edible protein powder.
At present, the recognized high-quality protein in nutritional research is animal protein and soybean protein, which exist in most eggs, meat products and bean products. These foods not only contain various amino acids, minerals and vitamins, but also contain some bioactive factors that are being studied or to be developed, such as soybean isoflavones in soybeans, lecithin in eggs and unsaturated fatty acids in fish, which can reduce the concentration of triglycerides in blood and reduce the risk of coronary heart disease. The vast majority of protein powder sold in the market is produced by deep processing of soybeans. Although its protein content can be as high as over 90%, its nutritional value has been greatly reduced due to the loss of other nutrients during processing, which is not the same as that of natural food.
Of course, protein powder is not useless, it also has a special applicable population. For some people with special physiological periods, such as hospitalized patients, patients with intestinal diseases and patients with advanced cancer, it is necessary to supplement protein appropriately, because their digestion and absorption ability is poor. It is worth noting that excessive supplementation of protein is also harmful to human health. First of all, it will increase the burden on the kidneys. Under normal circumstances, the human body must deamination and decompose the excess protein, and excrete the decomposed nitrogen through urine, which requires a lot of water and a healthy and tough kidney. If the renal function is not perfect, taking too much protein will pose a threat to health. Secondly, excessive intake of protein may also increase the loss of calcium in urine and damage bone health. Therefore, people who usually eat eggs, meat, fish or beans do not need to eat protein powder at all.
