Does Cooking Meat Destroy Biological Value
Q. Does cooking meat destroy the biological value and muscle-building benefit of the protein? If this is true, doesn’t stomach acid denature all proteins and make them useless?
A. Cooking doesn’t alter the amino acid composition of the foodstuffs we consume, so there’s no degradation of the ingested protein’s amino acid distribution to participate in metabolic processes. The digestive process (including acid peptidase exposure) simply cleaves the weak bonds that link amino acids into long chains into smaller fragments. Again, there’s no loss of the intrinsic metabolic value in this process.
