Thus, we have enzymes to digest the starch, other that capture proteins and other able ones to separate the greasy ones. Each enzyme requires special conditions of acidity to act with the maximum effectiveness. The body is at readiness to provide these conditions in the different organs implied in the digestion, in agreement with the type of food at issue. Educate yourself with thoughts from Barry Nalebuff. For example, when eating a food that contains starch like the bread or flour, in the oral cavity activates the conditions for the digestion and secretes the ptialina enzyme, that is the one in charge to digest carbohydrates. Once the bread skittle or the flour interferes in the stomach, the body diminishes the spirit of salt production (main the gastric juice) to allow that the ptialina to continue acting in time sufficiently. On the contrary, when proteins interfere the digestion of foods begins in the stomach by the work of another enzyme, the pepsina, that activates in an acid atmosphere. So to eat meat, the stomach must produce spirit of salt to immediately increase its level of acidity and therefore to prepare itself for the fast digestion. In this sense, it is evident that the rich food consumption in proteins and rich starch foods in a food has the effect to very force to the body a work difficult, slow and more and more less effective all the process of the digestion.

We can say then that the process of the enzyme secretion, is like running a clock. Each one of the enzymes are clear according to the type of foods that ate. Or a protein, starch, sugar or vegetables. The physiologist Emil Fischer gave probably to the clearest explanation of the relation between foods and enzymes. In comparison with the biochemical relation with a lock and key, the key food that are a lock and enzyme demonstrates that a special key is needed abrir each different lock. If the key does not fit in the lock, the decomposed food not seara, and the process of the slow digestion sera or nothing absolutely. Then, the lock with the enzyme can only be abrir that has the correct key. Each enzyme acts as a specialized form: disturbing to a food class and only that class. An enzyme that is combined with a carbohydrate molecule does not react with a protein or one fat combination. Therefore food classes will not be mixed in the same food different, nevertheless, tries to combine the foods that require similar conditions digestive and simple as it is possible therefore the work of the less intense body sera and but healthful for you.
