Protein quality

 

According to nutritional science findings of the past 50 years, the body needs about 12.5 g of essential amino acids a day to be able to build the hormones, enzymes, muscles, transport protein, etc. Excessive protein supply does not make sense because the body cannot store protein. A small amino acid pool exists in the blood and the body converts surplus protein into nitrogen and ammoniac. Both leave the body through the kidneys and the skin. The permanent supply with protein is decisive here as well. Less but regularly is the motto.

 

When we eat protein, the stomach breaks it down to amino acids (dipeptides and tripeptides). Those amino acids need to be put back together to the single components, according to requirement, in the liver. If there is not enough of one amino acid, the body cannot use the protein completely. The needs-based supply, as determined by science, of all amino acids is thus important. Protein quality is also called “biological quality”. Attention: The biological quality nowadays is often determined based on the outdated reference profile (chicken egg) which is from 1968 and still used by most nutrition consultants today (food nutrition data base Bundeslebensmittelschlüssel BLS).

According to the latest recognized protein profile (DIAAS method), the protein quality of iSANO Vegan is better than the one of meat (beef steak). The profile of “healthy nutrition” is on the left, the profile of iSANO Vegan on the right.
