Full Answer

The pH is the measurement of acidity and alkalinity of any chemical, usually calculated by the decimal logarithm of the reciprocal of hydrogen ion activity in an aqueous solution of that chemical. The pH scale ranges from 0 to 14. On the pH scale, 7 is considered to be neutral and represents a substance that is neither acidic nor basic. The lower is the pH value of a substance, the more acidic it is; values higher than 7 are associated with substances that are basic in their nature.

There are several other foods that are listed in the neutral category and also have a pH of 7. These include milk, vegetable oil and butter. The pH of other foods varies widely and depends on if the food is an alkali-forming food or an acid-forming food. For example, alkali foods, such as soy beans and lima beans, both have a pH of 12. Acid-forming foods, such as organ meat, liver and chicken, all have a pH of 3.
