pH scale

The pH is a measure of liquid acidity/alkalinity. It ranges from 0 to 14, where 0 is most acidic and 14 is most alkaline. The more acidic, the more hydrogen ions (h+) it contains. (1, 2, 3)

Examples of pH:

  • Battery acid = 0.3
  • Lemon juice = 2.2
  • Vinegar = 2.8
  • Gastric (stomach) acid = 1.5-3.6
  • Orange juice = 4.2
  • Milk = 6.7
  • Distilled water = 7 (perfectly neutral)
  • Blood = 7.4 (4)
  • Sea water = 8
  • Baking soda = 8.4
  • Ammonia = 11.5
  • Bleach = 12.6

Do acid-forming foods make urine more acidic? Acid-ash foods contain minerals which lower the fluids' pH. To maintain the blood at its optimum acid-base level the body removes the acidic substances trough urine, making it more acidic.
Does a diet high in acidic foods make the urine acidic? Acidic foods (foods with low pH) don't necessarily influence the acid-base balance of the urine. Urine's pH depends rather if the they are acid-forming or base-forming foods.
Did our ancestors really eat mostly alkaline foods? Contrary to what the supporters of the alkaline diet believe, only 40%-50% of people before the beginning of agriculture had a net acid-producing diet.
Difference between acidic food and acid-forming food Acid-forming foods and acidic foods are unrelated and produce different effects on the body. Acid-forming foods may reduce the urine pH level, with no impacts on health. Acidic foods don't have an impact on the body's pH...
Does milk cause osteoporosis? Milk, dairy products and milk derived supplements are good for bone health. The acid-ash hypothesis, which this myth originated, has been disproven by many studies.
