Whey is also a complete protein, meaning it contains all the essential amino acids. Cottage cheese is another popular source of protein, as it contains whey and casein, so it covers both bases. Now, if you can't digest dairy products, opt for lean proteins from whole foods, such as eggs, seafood, or lean meats, and keep your fat intake low after training and your carbohydrate intake high to speed up absorption. Some proteins move more easily through the digestion process, making them available more quickly for the body to use.
In addition, the IoPEA protein is the first vegetable protein with a bioavailability similar to that of whey protein. Whey protein powder, the most common form of dairy-based protein powder, is the liquid by-product of making cheese. To carry out any of the functions of protein, the body needs access to amino acids, which are the building blocks of proteins. They are then recombined by synthesizing proteins into other proteins, which the body can use to build muscle, among other things.
You can see that drinking all the whey protein at once (bolus) increased protein synthesis more than distributing the same amount of whey over 3 hours (pulse). The other difference between whey protein and casein protein is how quickly the protein is absorbed and for how long. For example, when evaluating the impact of IoWhey Protein compared to a non-optimized whey protein in an 8-week study with male and female athletes, protein supplementation was combined with resistance training. In 2004, dairy proteins were the main source of protein in sports supplements, approximately three-quarters of them.
Learning about slow-digesting and fast-digesting proteins can help you make good decisions about the types of proteins you eat. Drinking 25 grams of fast-digesting whey protein, all at once and immediately after exercise, increases muscle protein synthesis more than drinking 25 grams of whey protein for 3 hours after exercise. Leucine, in a unique way, activates skeletal muscle protein synthesis through a series of molecular biological interactions similar to those in dominoes, called the mammalian rapamycin target pathway (mTOR). Similarly, people with digestive problems or other gastrointestinal problems, as well as those recovering from illness or medical procedures, often benefit greatly from increasing their protein intake.
Casein is an example of a slow-digesting protein, which remains in the blood for four to five hours before being absorbed, providing a slow-release effect.
