The pH of most fruit juice ranges between 6 and 7, a low level of acidity. The exception to this is lemon juice which is an acidic 2.3 on the scale.


The human body functions best at a slightly alkaline level and an imbalanced diet of acid-rich foods can lead to problems in the body's ability to heal itself. In order to avoid long-term damage, balance your acid-alkali levels, starting with your fruit intake.
