Does cooking decrease protein?

A study on the amino acid contents of raw, cooked and fried fishes no found differences in individual amino acids as result of frying (47). In general, the content of protein is increased by the frying process due the effect of concentration, because frying is also a process of dehydration.

Can protein be killed?

Overloading on protein rather than eating a balanced diet can also run the risk of you not getting other nutrients you need in the form of fiber, carbohydrates, vitamins, and minerals vital to good health.
