If you simply want to know whether the human body is acidic or alkaline, it is purely a medical problem, then the answer upstairs is correct, and the PH value is 7.35-7.45, with an average of 7.4, which is weakly alkaline.

If you want to know whether the human body is acidic or alkaline from the perspective of health preservation, and rely on acidic or alkaline foods to regulate it, then tell you that the popular saying that "relying on so-called acidic or alkaline foods to regulate the acidity and alkalinity of the human body" is purely misleading, and some so-called dietotherapy experts take it out to deceive people. In the northeast, call it a fool.

Why? Because there are several main ways for substances to enter the human body, the first is oral intake (the main way of food and oral drugs), the second is nasal inhalation (the main way of air), and the third is intravenous drip (the main way of intravenous drugs).

No matter what the so-called acidity or alkalinity is, the food that enters the body through the mouth is gastric acid at first, and the PH value is close to 1, which belongs to strong acid. No matter what food drugs enter strong acid, it basically doesn't matter whether they are acidic or alkaline. The alkalinity is neutralized, and the acidity is not as big as stomach acid. Therefore, if the acidity and alkalinity of food are soluble in water, it will have an impact on the pH value of the human body, which is nonsense.

The gases that enter the body through the air are mainly oxygen and nitrogen, and the body produces carbon dioxide, which dissolves in the blood to produce carbonic acid, which is weakly acidic. However, the human body has a very large buffer system, and that little weak acidity is quickly neutralized, just like a stone thrown into the sea, which is calm, but the disease state can cause excessive accumulation of carbon dioxide, leading to acidosis, and the PH will begin to be acidic. This acidity can never be corrected by food and must be used.

The acid-base solution given through vein is a challenge to the buffer system of human body. When drugs overcome human beings, acid-base poisoning appears, which is very dangerous and life-threatening. It must be treated by adjusting breathing and intravenous drugs.

In short, the human body can survive because of its strong acid-base balance buffer system, which is difficult to be affected by food, so don't believe the words of "health experts" and eat acidic food and alkaline food to keep healthy.
