It looks like a universal protein powder. Are you really suitable for eating?

Since Amway entered China, protein powder has been known by Chinese people And Yao Ming's endorsement of a brand has made it into thousands of households Protein powder was once regarded as high-quality nutrition and health care products, and was placed on the table of the elderly, patients and high school students However, do you really understand it in the process of eating? What is the role of protein for the human body? The textbook says that protein is the material basis of all life and the existence form of life Without protein, there is no life The protein content of normal human body is about 16% - 19% of body weight Its main physiological functions are: building the body, repairing the tissue It constitutes almost all active substances in the body and maintains and regulates physiological functions Energy supply, 1g food protein can provide about 4kcal energy How do we usually take in enough quantity to maintain the basic needs of the body? The diet of Chinese people is mainly grain, so half of the protein we need is from non-quality protein of plants, and the utilization rate is relatively low The protein contained in soybean food is the high quality protein from plant This requires us to reasonably match some animal foods in our daily diet, such as lean meat, fish and shrimp meat, poultry meat, etc., the protein in these foods belongs to high-quality protein, with good quality and high utilization rate If matched with our cereal food, it can make protein complementary and greatly improve the utilization rate of protein The recommended intake of protein formulated by the Chinese Nutrition Society is 80g / D and 70g / D for physical activities of adult men and women, and 5-10g for light and heavy physical activities Therefore, as long as our normal people eat a balanced diet and adhere to daily food diversification, there is no need to add protein powder People with low immunity are particularly easy to catch cold, and immunoglobulins in it can enhance immunity Whey protein is beneficial to wound healing and accelerate the repair of the body Hypoalbuminemia caused by energy deficiency due to low dietary intake Those who need to improve their brain and memory It is rich in tryptophan, which can be converted into taurine in vivo and promote the growth of brain cells People who are keen on bodybuilding and slimming Whey protein can increase the synthesis of muscle protein Pregnancy and postnatal recovery Sufficient protein is good for mother and child health There are two kinds of protein powder: whey protein powder and soybean protein powder Whey protein powder: whey protein belongs to animal protein, which contains all necessary amino acids for human body (essential amino acids refer to those indispensable for human body, but cannot be synthesized in vivo, and must be obtained by food) The absorption rate of human body can reach 99% It is rich in nutrition similar to mother colostrum, and widely used in the production of infant formula For fitness enthusiasts, whey protein powder is a very good protein supplement Whey protein supplementation after exercise can increase the growth of muscle tissue, so as to achieve better fitness effect This is not the effect of soy protein powder There is another kind of soybean protein powder: soybean protein is plant protein, and its absorption effect is worse than whey protein, but its production cost is lower and its price is cheaper In the process of taking protein powder, what should we pay attention to? Do not take protein powder on an empty stomach Protein is easily absorbed and utilized by the body as energy, resulting in protein waste You can add milk, congee, juice to drink, or bread Do not use boiling water to brew at a temperature of about 40 ℃ If the water temperature is too high, it is easy to destroy a variety of active substances contained in it and reduce the biological potency of protein After exercise, if it is to increase muscle or reduce weight, it is better to supplement 20-40g whey protein 30-40min after exercise Not the more the better the protein powder is not the more the better Excessive protein is easy to cause the burden of liver and kidney, especially for people with abnormal liver and kidney function, which is not suitable for additional protein If necessary, they should also take it under the guidance of doctors or nutritionists, or "tonics" will become "drugs" In short, water can carry a boat, but also can capsize it Only scientific and reasonable application of protein powder can we get the effect of strengthening body At present, there has been a variety of nutrients better than protein powder, namely protein peptide Protein peptide belongs to small molecule active peptide, which has small molecular weight, does not need to be digested and directly absorbed After being eaten by human body, protein powder needs to consume body energy, wear human organs to digest into small molecule peptide, so it can be further absorbed by human body This also agrees with scientific research conclusion: human body absorbs protein in the form of small peptide The protein powder that has been eaten is not completely digested, and part of the protein powder that has not been digested remains in the stomach and intestines, which is easy to cause discomfort such as flatulence and diarrhea For the elderly or children with low gastrointestinal function, it undoubtedly increases the body burden Protein peptide is not only suitable for protein powder, but also for radiation chemotherapy patients and people who are often exposed to radiation Secondly, the way of taking protein peptide is simple and direct There are no rules and regulations for protein powder It can be taken before and after meals, after exercise, and when mixed with drinks.
