In the normal metabolism process, the human body constantly produces acidic substances and alkaline substances, and also ingests acidic substances and alkaline substances from food. Acidic substances and alkaline substances are constantly changing in the human body. However, because the human body has a certain ability to adjust the acid-base balance, it can maintain the acid-base balance in the body under normal circumstances. This balance is the acid-base balance, the balance range is 7.35-7.45, and the average value is 7.4 1. If the pH value in the human body is often lower than 7.35, it is called acidic constitution.
The normal pH value of human body is 7.35-7.45, which is weakly alkaline. The most suitable pH condition for immune cells in human body is 7.35-7.45. Under this condition, immune cells have the strongest fighting capacity and the best immune function. However, if the pH value deviates, the activity of immune cells will be greatly reduced, and the immune function will be weakened, while some viruses and bacteria have the strongest activity under acidic conditions.
