Whey protein is one of the most widely used protein supplements available today. But what is whey protein? Why do you need it? Does it really help?
Read on to know the benefits of drinking whey protein and more!
What is Whey Protein?
Whey is the translucent part of milk (full fat) that is collected after it undergoes the process of coagulation (a process that tangles milk proteins (casein) into solid masses or curds) due to the addition of certain substances (enzymes like rennet or rennin). The whey proteins thus separated are purified using various techniques to obtain whey proteins of various concentrations.
Whey proteins contain Branched-Chain Amino Acids (BCAAs), which stimulate protein synthesis. It is also rich in vitamins and minerals. Not only can you find whey proteins in sports nutrition, but you can also find them in baked goods, salad dressings, emulsifiers, infant formulas, and medical nutritional formulas. The protein concentration varies depending on the forms of whey proteins.
Forms of Whey Protein
There are three major forms of whey proteins: concentrate, isolate, and hydrolysate.
- Whey protein concentrate: It contains 35-80% protein with fat, lactose, and minerals making up the rest. It is the least expensive.
- Whey protein isolate: It contains 85- 90% protein with a tiny proportion of fat or lactose.
- Whey protein hydrolysate: It comprises proteins that have undergone hydrolysis by the use of proteolytic enzymes for easier metabolizing. It is the most expensive.
Thus, one can choose whey proteins according to their affordability, needs, or as advised. Lactose-intolerant individuals can also consume whey proteins with low lactose content (for example: whey protein isolates) to avoid major side effects.
