Frying has little or no impact on the protein or mineral content of fried food, whereas the dietary fibre content of potatoes is increased after frying due to the formation of resistant starch.
Does frying destroy protein?
When protein is heated, it can ‘denature’- this means the protein molecules unfold or break apart. This is what your body does to protein anyway, breaking down the amino acids and digesting protein. Much like when you cook meat, the protein you gain is not altered by cooking.
