Alkalinity is better, but acidity does no harm. Modern medical research shows that healthy body fluids are weakly alkaline. If the body fluid is acidic, it will lead to the decline of human immunity, and all kinds of harmful substances will take advantage of it and have a negative impact on human health. Therefore, as a healthy drinking water, the PH value must be weakly alkaline, so that alkaline ions in the water can promote the best state of the human body by adjusting the pH value.
Most people in modern times are more or less acidic. Drinking healthy water with weak alkaline PH for a long time can neutralize excessive acidic substances in the body, adjust the acid-base balance of the human body, effectively improve the physique and make the human body reach a healthy state. However, the water in nature is acidic, and the influence of science on human health and the acidity and alkalinity of drinking water are still inconclusive. A very concrete example is the carbonated drinks we drink every day, such as coke and sprite.
Extended data:
The PH value even reaches the range of 2-3, which is nearly a thousand times higher than the acidity of pure water, but it is harmless to human body. All foods contain more chlorine, sulfur and phosphorus, and the final metabolites in the body are acidic, so they are acidic foods. Fish and shrimp, eggs, cereals, peanuts, walnuts, hazelnuts and other foods contain a large number of elements such as calcium, potassium and magnesium, and the final metabolites in the body are alkaline and belong to alkaline foods.
Grasp the acid-base balance, but also meet the body's demand for water. Including the water in food, the daily intake of water should not be less than 2000 ml. In order to maintain metabolic balance, maintain body fluid balance and reduce salt intake, it is also an important aspect not to exceed 5 grams per day. Many foods contain sodium, so the diet should be light and light. This is also an important factor to keep healthy and prevent aging. Eat more fruits and vegetables, supplement vitamins and minerals in the body, and neutralize excess acidic metabolites in the body.
