pH

The lists below categorize foods that are either acidic or alkaline based on the effect they have on urine pH. For example, if a food tends to increase the acidity of urine after it is ingested, it is classified as an acid forming food. Conversely, if a food increases the alkalinity of urine after it has been ingested, it is classified as an alkaline forming food. The effect foods have on urine pH may be quite different than the pH of the foods themselves. For example, orange juice is a highly acidic food due to its high citrus acid content, but after being metabolized it will cause urine to become alkaline.
