Stomach acid and alkaline watery

Alkaline Water and Stomach Acid

by Sang Whang

Among the people who question the validity of alkaline water, the biggest question is; "What happens to the alkaline water once it reaches the stomach, which is highly acidic?" People who have some knowledge of the human body, including medical doctors, ask this question. Let me answer that question once and for all to erase any doubts about the health benefits of alkaline water.

In order to digest food and kill the kinds of bacteria and viruses that come with the food, the inside of our stomach is acidic. The stomach pH value is maintained at around 4. When we eat food and drink water, especially alkaline water, the pH value inside the stomach goes up. When this happens, there is a feedback mechanism in our stomach to detect this and commands the stomach wall to secrete more hydrochloric acid into the stomach to bring the pH value back to 4. So the stomach becomes acidic again. When we drink more alkaline water, more hydrochloric acid is secreted to maintain the stomach pH value. It seems like a losing battle.

However, when you understand how the stomach wall makes hydrochloric acid, your concerns will disappear. A pathologist friend of mine gave me the following explanation. There is no hydrochloric acid pouch in our body. If there were, it would burn a hole in our body. The cells in our stomach wall must produce it on an instantly-as-needed basis. The ingredients in the stomach cell that make hydrochloric acid (HCl) are carbon dioxide (CO2), water (H2O), and sodium chloride (NaCl) or potassium chloride (KCl). NaCl + H2O + CO2 = HCl + NaHCO3, or

KCl + H2O + CO2 = HCl + KHCO3

As we can see, the byproduct of making hydrochloric acid is sodium bicarbonate (NaHCO3) or potassium bicarbonate (KHCO3), which goes into blood stream. These bicarbonates are the alkaline buffers that neutralize excess acids in the blood; they dissolve solid acid wastes into liquid form. As they neutralize the solid acidic wastes, extra carbon dioxide is released, which is discharged through the lungs. As our body gets old, these alkaline buffers get low; this phenomenon is called acidosis. This is a natural occurrence as our body accumulates more acidic waste products. There is, therefore, a relationship between the aging process and the accumulation of acids.

By looking at the pH value of the stomach alone, it seems that alkaline water never reaches the body. But when you look at the whole body, there is a net gain of alkalinity as we drink alkaline water. Our body cells are slightly alkaline. In order for them to produce acid, they must also produce alkaline, and vice versa;
