Protein is the material basis of life and is one of the three major components of the human body. The lack of protein will directly lead to growth retardation, low immunity, loose skin and premature aging. Plant protein powder good and whey protein powder both contain high quality protein, then, plant protein powder good or whey protein powder good? Plant-based proteins are mainly derived from rice and noodles and legumes, but the nutritional value of proteins from rice and noodles and legumes is different. Lysine (an essential amino acid) is missing in proteins from rice and flour sources, so their amino acid score is low, only 0.3-0.5, and the degree of absorption and utilization of these proteins by the human body will be poorer. Of course, this deficiency can be improved through scientific methods, such as adding lysine-rich legumes to rice and noodles, which can significantly improve the amino acid score of proteins. Whey protein powder is a complete protein extracted from fresh milk, whey protein (wheyprotein) is known as the king of proteins, is a kind of protein extracted from milk, which contains a complete group of essential amino acids, high-quality protein content of more than 80%, mainly by the β-lactoglobulin, α-lactalbumin, bovine serum proteins, immunoglobulins, lactoperoxidase, lysosomes, Lactoferrin and other components, with high nutritional value, easy to digest and absorb, contains a variety of active ingredients, etc., is currently recognized internationally as one of the most comprehensive nutritional natural protein, but also our first choice for protein supplementation. Plant protein should theoretically be cheap, but in fact the domestic market to do plant protein business, such as (a catalyst to) the price of plant protein powder is whey protein powder prices nearly three times, they 500 grams of a can of plant protein powder to be sold to more than 300, the equivalent of whey protein 2-2.5 pounds of price, really pit people bottomless ah.
