Do I have to eat a special diet to achieve the right acid balance in my body?

No, because the body has an exquisite system for making sure that the blood maintains the proper pH, the chemical term for the concentration of hydrogen ions.

A pH of 7 is considered neutral. A pH of lower than 7 is acidic, higher than 7, basic or alkaline. Normal blood pH is tightly controlled so that it stays between 7.35 and 7.45.
