Whey protein is a kind of milk extract, which has good taste and rich kinds of amino acids. Can be quickly absorbed and utilized by the human body. It is a good choice for muscle building and is suitable for fitness enthusiasts.
Casein, like whey protein, is also a milk extract. The difference is that the absorption rate of casein is obviously low, but it can release amino acids stably and continuously for several hours, which is suitable for taking before going to bed.
Soybean protein is extracted and separated from soybean, and its absorption and utilization rate is lower than whey protein and casein, but it is rich in active substances such as soybean isoflavones, which is suitable for middle-aged and elderly women. ?

People who are not suitable for eating protein powder:
1. Use with caution in patients with liver disease.
Because there are obstacles in the processing and utilization of protein by the liver, the intake of protein should be appropriately increased. However, for patients with hepatic coma and advanced cirrhosis, too much protein will increase the burden on the liver and aggravate the condition, so animal protein should be restricted.
Because its metabolism in the body will produce more ammonia, which can induce or aggravate liver coma, such patients can choose some plant proteins rich in branched-chain amino acids, especially soybean proteins. Because branched-chain amino acids are mainly metabolized in muscles, they have protective effects on liver function.
2. Children under three years old should not eat.
Newborns should not eat protein powder, and the best nutrition for babies is breast milk. If children can't eat breast milk for various reasons, they should choose formula milk powder of the corresponding month or age instead of protein powder, because the protein component of the latter is not suitable for children, which is not conducive to children's digestion and absorption, and may cause vomiting, diarrhea or allergies after eating.
3. Gout patients should choose carefully.
Eat protein powder with soybean protein as the main component. Because the purine in soybean will increase uric acid in the body and promote or aggravate gout. However, some brands of soybean protein powder have been specially treated to reduce the purine content.
