Animal proteins:

What is this ?

In food supplements intended for athletes , two types of proteins are consumed: proteins from the liquid fraction of coagulated milk (whey) also called “ whey protein ” and those from the micellar fraction , “ caseins ”. These two types represent the main protein fractions of milk.

 What are they for?

Proteins are the major functional and structural components of all cells in the human body. About half of these are present in skeletal muscles . Once ingested, proteins are broken down into amino acids, some of which (like glutamine) are energy components of intestinal cells and immune cells.

Most passes to the liver, where some is retained and used, particularly in energy and protein metabolism . The rest enters the blood circulation and is used by the various tissues, notably the skeletal muscles. Proteins are mainly rejected in the feces. Other routes of elimination of nitrogen (the majority component of proteins) are urine, sweat, skin and hair (IOM 2005).

 

What nutritional contributions?

The EFSA (European Food Safety Authority) has validated the following two claims: “ protein helps increase muscle mass ” and “ protein helps maintain muscle mass ”. These claims can only be used for a food that is at least a source of protein (at least 12% of the energy value of the food must be produced by protein) (EFSA 2010b, 2011d).

Plant proteins:

 

What is this ?

Soy protein comes from soybeans (legumes). It can be ideal because it contains few saturated fatty acids and no cholesterol . Soy protein contains all the essential amino acids that must be provided by food, with a good supply of lysine and arginine .

 

What is it for?

Soy proteins help reduce cholesterol and blood triglyceride levels, which reduces cardiovascular risks . They play a role in preventing bone weakening (osteoporosis).

Soy protein also contains isoflavones that help build bone density . In addition, isoflavones act as hormones in the body, we speak of phytoestrogens (plant estrogens). The isoflavones most present in soy are genistein, daidzein and glycitein.

Once ingested, soy proteins follow the same metabolic steps as animal proteins.

Collagen:

What is this ?

Collagen is part of the structural protein family. It is present in the extracellular matrix and provides mechanical resistance to tissue stretching and plays a main role in the cohesion of organs and tissues . Collagen is the most abundant protein in the body.

What is it for?

Collagen is the main constituent of joints. This therefore makes it possible to renew and maintain the articular cartilage in order to avoid pain and maintain flexibility and elasticity.

Collagen also has a good water retention capacity which allows the production of synovial fluid which plays a lubricating role in the joints. This water retention capacity also helps keep the skin resilient, supple and elastic as hyaluronic acid allows.
