The pH value of human blood and body fluids is controlled by a set of dynamic and balanced metabolic mechanisms, which can keep the pH value in blood at a constant value (7.35-7.45). The so-called "healthy only when the body is alkaline" is completely unbelievable. Normal people's blood pH is about 7.4, which is weakly alkaline, while stomach, skin and female vagina must be acidic to ensure normal physiological functions.
The most important factors affecting the imbalance of body pH are diseases and drugs, and even the respiratory process has a greater impact on blood acidity than food. Some metabolized energy substances will be converted into carbon dioxide, which will combine with water in the body to form carbonic acid. Breathing will make a lot of acid enter and leave the human body at any time. This stability under long-term adaptation is completely unaffected by a bottle of weakly alkaline water.
Extended data:
Nutritionists did divide foods into acids and bases in the past. For example, most vegetables and fruits are alkaline, while meat and grains are mostly acidic. The acidity and alkalinity of food is far less than that of the stomach. Under normal circumstances, food will be acidic in the stomach and weakly alkaline in the intestine.
From the perspective of health management, many diseases are related to improper diet, insufficient exercise, and inattention to stay away from pollution, which requires people's daily attention.
