First of all, we have to make it clear that the so-called "acidic body" does not exist.

Many people think that "acidic constitution" refers to the body's high acidity, but this is not the case. The blood of healthy people is weakly alkaline, with a pH value of about 7.4. Under normal physiological conditions, acid-base imbalance in human blood is unlikely to occur.

When the acidity or alkalinity of human blood temporarily increases, the respiratory system will react within a few minutes to accelerate or slow down the discharge of carbon dioxide (acidity) to adjust the pH value back to normal within a few minutes; The kidneys, urine excretion system and blood system also regulate pH, so normally, no one's blood is acidic (pH<7.0).

The pH of the human body and the pH of food are two completely different concepts. Food will not change the pH of the human body, but eating more alkaline foods is still good for the body.

Alkaline foods refer to foods with high content of calcium, magnesium, potassium, sodium and other metal elements, such as vegetables, fruits, etc.
