There is no scientific evidence to support the claim that we can heal ourselves by keeping our body alkaline. In fact, our body has different pH levels for different compartments, such as the blood, the stomach, the urine, and the cells. The pH level is a measure of how acidic or alkaline a substance is, ranging from 0 to 14, with 7 being neutral. The body regulates its pH levels very tightly to maintain optimal functioning and health 1 . The blood is slightly alkaline, with a normal pH range of 7.35 to 7.45. If the blood becomes too acidic or too alkaline, it can cause serious health problems, such as metabolic acidosis or metabolic alkalosis. These conditions are usually caused by underlying diseases or disorders that affect the kidneys, lungs, or other organs, not by the food we eat 2 . The stomach is very acidic, with a pH of around 2 to 3. This helps digest food and kill bacteria that may enter the digestive tract. The stomach acid is neutralized by bicarbonate in the small i...
