The Acid-Alkaline Diet
The acidity of any liquid solution can be measured using a standardized scale called the pH scale, which ranges from zero to 14. Solutions with a lower pH are termed acidic, whereas solutions with a higher pH are termed basic, or alkaline. Solutions with a pH near 7 are classified as neutral. The pH of the fluids in your body, such as saliva and urine, generally falls between 6.75 to 7.25. The pH of your blood is usually between 7.35 and 7.45. The goal of the acid-alkaline diet is to consume the types of foods that can keep the pH of these fluids steady.
