Extended data:

Protein foods, such as meat and eggs, need to be digested in strong acid gastric juice, while starchy foods, such as bread, need to be beaten in alkaline environment. If the above foods are eaten together, protein food and starchy food cannot be digested at the same time.

When starch stays in the stomach and waits for digestion, it is easy to cause the fermentation corruption of sugar, which leads to the overload of gastrointestinal tract, so it is easy to cause fullness, acid regurgitation or oral odor, and also affects the absorption of nutrients.

Acidic fruits such as lemons and oranges, or vinegar and organic acids enter the body, are neutralized by pancreatic juice, bile, intestinal juice and carbonic acid, and are absorbed by the liver, and soon burn into carbon dioxide, which will not cause a burden to the body.
