The great nutritional value of milk has been recognized by the public. However, whey protein, which is much higher than the nutritional value of milk and is called "milk essence", has only been quietly popular among fitness people for a long time, and many people don't understand it. At the "2006 symposium on whey protein nutrition" held on July 20th, nutrition experts at home and abroad agreed that whey protein should become people's health care products because of its high absorption, complete amino acid composition, low fat and cholesterol content and comprehensive health benefits.
Dr. Alan G. Hugunin, an American food and dairy expert, pointed out that whey protein can provide high-value nutrition more conveniently and effectively than milk. At present, a popular nutrition bar in the United States is composed of milk protein and other nutrients in a reasonable proportion. For those who don't have time to eat breakfast, you can even eat while driving, which can basically replace a meal, which is very convenient. It is said that the nutritional value of 1 teaspoon whey protein powder is more than 5 eggs. Studies have shown that whey protein not only plays an important role in building all important muscle groups and repairing human cells, but also has significant effects in anti-aging, promoting heart health, improving immunity, increasing bone density and controlling weight, especially suitable for pregnant women, children, the elderly, patients and bodybuilders. For office workers who are prone to fatigue and have no spirit, supplementing whey protein can also keep you energetic.
However, supplementing whey protein is also tricky. Professor Zhao, honorary chairman of Shanghai Nutrition Society, said that milk protein belongs to high-efficiency and high-quality protein, and it is enough for adults to supplement 8- 10 grams a day. He also reminded that high-quality protein must be eaten with carbohydrates. This is because if you only eat high-quality protein and don't eat staple food, then the protein you eat will be used as a substitute for carbohydrates, which will be burned in vain as energy and will not play other important roles.
What is whey protein?
Whey protein is a kind of protein with high nutritional value and multiple functional components, which is separated and extracted from milk. Milk is 87% water and 13% milk solid. Milk solids contain 37% lactose, 30% fat and 27% milk protein. In milk protein, 80% is casein and 20% is whey protein, which is the essence of milk.
