This research rejects the claims of the alkaline diet, and explains that dietary intake can only influence the urine pH, Accordingly, blood pH is regulated by several organs and mechanisms in the body, among them are kidneys and respiratory functions.
What Impact Does pH Have on Food and Nutrition?
Acidity and alkalinity are measured on the pH scale, which ranges from 1 to 14, with 1 the most acidic, 14 the most alkaline, and 7 being neutral. Most foods have a pH below 7. The pH scale is important in home canning because low-acid foods—defined as having a pH above 4.6—do not contain enough acid naturally to prevent the germination and growth of the botulinum spores found on most fruits and vegetables that come in contact with soil (1).
