Virtually all pH in the body is regulated through respiration and kidney function

The kidneys produce bicarbonate ions that neutralize acids in your blood, enabling your body to closely manage blood pH

loss of collagen is strongly linked with low levels of two acids — orthosilicic acid and ascorbic acid, or vitamin C — in your diet

Clinical trials — which tend to be more accurate — have concluded that acid-forming diets have no impact on calcium levels in your body

Many people argue that cancer only grows in an acidic environment and can be treated or even cured with an alkaline diet. However, comprehensive reviews on the relationship between diet-induced acidosis — or increased blood acidity caused by diet — and cancer conclude that there is no direct link

cancer grows in normal body tissue, which has a slightly alkaline pH of 7.4. Many experiments have successfully grown cancer cells in an alkaline environment

while tumors grow faster in acidic environments, the tumors create this acidity themselves. It is not the acidic environment that creates the cancer, but the cancer that creates the acidic environment

while lemon juice may make the pH of the urine more alkaline, it does not have the same effect on the pH of your blood. Numerous studies show that the foods you eat have a very limited effect on blood pH
