Protein in the diet: how does heat treatment affect protein absorption from food?

The cooking process directly affects how many nutrients our body will actually absorb. Raw foods are not always the best choice, as heat treatment often destroys antinutrients and makes the protein structure more accessible to digestive enzymes. However, excessive or improper cooking can completely destroy valuable amino acids.

With moderate heating, protein molecules denature, meaning they unfold from complex spirals into simple chains. It becomes much easier for our stomachs to break down such structures into individual amino acids. This is why boiled meat, fish, or eggs are absorbed by the body much more efficiently and quickly than raw foods.

On the other hand, overly aggressive cooking methods, such as heavy frying until a black crust forms or prolonged baking at very high temperatures, ruin the quality of the protein. Under such conditions, amino acids react chemically with sugars, forming compounds that the stomach is practically unable to process. This not only reduces the nutritional value of the dish but also creates additional stress on the digestive system.

To get the maximum benefit from your food, consider the following culinary processing rules:

Careful handling of food preparation allows you to preserve the maximum amount of benefits. Properly boiled chicken breast or baked fish will bring your body much more benefit than semi-finished products fried in oil.
