Is pure water acidic and harmful to your health?
A pH measurement is the intensity of a liquid in terms of its alkalinity or acidity. The pH scale goes from 0 to 14 where 7.0 is neutral. If the pH is above 7.0 the water is alkaline. If the pH is below 7.0 it’s acidic. Acidic liquids can range from battery acid to milk. For example the acidity of Battery Acid is 1.0, Wine is 2.3 to 3.8, Soft Drinks are 2.0 to 4.0, Coffee and Tea are 2.5 to 3.5, Beer is 4.0 to 5.0, Most Water 5.8 to 7.0, Milk 6.5.
Beverages can be consumed by the human body whether alkaline or acidic. According to the Merck Manual the world’s most widely used medical reference guide, the human body buffers to balance the pH. For example if you were to consume something acidic, your blood would produce more bicarbonate and less carbon dioxide to neutralize the acidity. Likewise, if you were to consume something alkaline, your blood would produce more carbon dioxide and less bicarbonate to balance out the pH.
Some sources want you to believe that consuming pure water will put your body in an acidic state and they recommend drinking water that is alkaline. Even if one was to consume alkaline water, once it hits the highly gastric fluid in the stomach, its alkalinity is gone. Claims about the health benefits of alkaline or acidic water are not supported by credible evidence.
