As we all know, protein is the main component of human muscles, bones, skin and other organs. Protein is helpful to improve sports performance, repair damaged muscles after exercise, and help restore muscle glycogen. Protein can be obtained from daily food, but few people can just get enough protein in real life, and the calories, fat and cholesterol contained in other foods do not exceed the standard, so protein powder is indeed a convenient substitute in some cases. Besides, whey protein has all other advantages that protein can't match when supplementing after exercise: it is absorbed quickly.

In addition to choosing whey protein, there are the following points to pay attention to:

1, taste and use of sweeteners

Protein powder itself has no taste, is not sweet or salty, and some protein powders are even bitter, while soybean protein usually has a strong bean smell. Therefore, most protein powders will use flavoring agents, or sugar substitutes, or natural, or a mixture of the two. Which flavoring agent has no effect on the nutrition of protein powder, only affects the taste. But if possible, try to choose naturally flavored protein powder. After all, sugar substitutes, especially aspartame (the main raw material in cola), have an impact on fat reduction efficiency.

2. Bad additives in protein powder

I think this is the main problem. The key to distinguish the quality of protein powder is to look at this. First, avoid putting some "fillers" in those cheap protein powders; Second, the most important thing is to avoid those series that put creamer (similar to coffee companion) in protein powder in order to improve the taste and concentration. As we all know, creamer is a pile of hydrogenated oil, trans fat and concentrated corn syrup, and good healthy food will also be turned into junk food by this.

3. Good additives

Common high-quality additives are:

Lecithin: Lecithin is a healthy fat extracted from soybean, which has the functions of enhancing memory and protecting cardiovascular health. Adding lecithin to protein powder can improve the solubility of protein powder and reduce caking.

Digestive enzymes: Adding digestive enzymes can help people digest protein better.

Amino acids: Whey protein contains all amino acids, but it is not balanced. Some brands will add glutamine, BCAA and arginine which are necessary for the body during exercise to improve the nutritional composition and value.

Carbohydrate and fat: Some bodybuilders like to use protein powder with carbohydrates and fat to supplement nutrition and help build muscles, but this kind of thing has its own name called muscle-building powder.
