king of protein | whey protein (whey protein) is called the king of protein. it is a kind of protein extracted from milk. it has the characteristics of high nutritional value, easy digestion and absorption, and contains a variety of active ingredients. it is recognized as one of the high-quality protein supplements for human body. Whey protein is a by-product when milk is made into cheese. When the milk is coagulated, the solid part is casein (commonly known as cheese, accounting for 80%), and the remaining liquid is whey (accounting for 20%). After a series of purification, it can become the can of whey protein in our hands. Because whey content is rare in milk, whey protein is particularly precious in comparison. |
The source of whey protein | The composition of milk is 87% water and 13% is milk solid. In the milk solid, 27% is milk protein, only 20% of milk protein is whey protein, and the rest 80% is casein, so the content of whey protein in milk is only 0.7%. |
efficacy and function | increase muscle mass skeletal muscle (also known as muscle) is the most dynamic and elastic tissue in the human body, accounting for about 40% of the total body weight. from a mechanical point of view, muscles convert chemical energy into mechanical kinetic energy, so that we can make various actions or maintain certain postures without relying on external forces. From other points of view, muscle is an important foundation of human metabolism. It has the task of storing protein and carbohydrates, and can produce heat energy and maintain core body temperature. Recent studies have also found that muscle is an important endocrine organ, which can secrete hormones collectively referred to as myokines, which can affect muscle quality and muscle fiber conversion, and play an important role in the process of carbohydrate, lipid metabolism and inflammation. It is a potential determinant of many chronic diseases. A systematic analysis (meta-analysis, including 22 randomized controlled trials, 680 samples) pointed out that regardless of age, under continuous and regular resistance training conditions, whey protein supplementation can help increase non-fat Weight (fat-freemass, mostly refers to muscle quality) and leg push strength. Another system analysis (meta-analysis) also pointed out that compared with the intake of carbohydrates or non-whey protein, the supplement of whey protein or multi-component compound after resistance training (resistancetraining) does help increase fat-free weight (leanbodymass, Refers to muscle quality) and the improvement of body strength in the upper and lower parts. Whey protein can help burn fat and accelerate weight loss People who want to lose weight often have the established impression that they will get fat after eating meat, which often causes insufficient protein intake. At this time, the body begins to break down muscles (muscle reduction will make the basal metabolic rate worse, which is not helpful for fat burning and weight loss at all). Studies have found that, compared with other proteins, whey protein has a superior efficiency in helping to burn fat. It can be used as a daily dietary supplement to make weight loss easier to achieve goals. It also has the following three effects. Inhibit appetite (eating enough protein will increase satiety and make you less want to eat junk food); Promote metabolism and help burn more calories; Maintain muscle mass and body function. |
nutritional characteristics of whey protein | among various proteins, whey protein has the highest nutritional value. Whey protein is a high-quality complete protein and animal protein. It contains 8 kinds of amino acids necessary for the human body, and the ratio is reasonable, close to the proportion of human needs, and is an indispensable essence of human growth, development, anti-aging and other life activities. Whey protein is easier to digest and absorb. Whey is rich in cysteine and methionine, which can maintain the level of antioxidants in the body. There are also many experimental studies that have proved that taking whey protein concentrate can promote humoral immunity and cellular immunity, stimulate the human immune system, and prevent the occurrence of chemical-induced cancer. So whey protein is a very good protein to enhance immunity. Whey protein contains low fat and lactose content, but it contains β-lactoglobulin, α-lactalbumin, immunoglobulin, and many other active ingredients. It is these active ingredients that make whey protein have many health functions beneficial to the human body, so it is considered to be one of the high-quality protein sources required by the human body. |
α-whey protein | α-whey protein is the dominant protein in breast milk, and its content accounts for 27% of the protein in milk. Alpha-whey protein can provide the best combination of amino acids, improve the bioavailability of protein, and adapt to the kidney load of infants. α-whey protein is rich in tryptophan, which is the precursor of the neurotransmitter serotonin and melatonin. It is alternately secreted by pineal cells: serotonin is secreted during the day, which regulates mood and appetite And behavioral neurotransmitters; melatonin is secreted at night, which is an endogenous sleep inducer and an important regulator of the inner biological clock. It helps babies sleep and promotes their brain development. clinical display: α-whey protein can increase the concentration of bifidobacteria, a beneficial bacterium in infant intestinal tract. the growth of bifidobacteria can regulate the balance of intestinal flora and inhibit the growth of intestinal pathogenic bacteria. |
