Alkaline diet
Alkaline diet


The alkaline diet focuses on eating foods that are slightly alkaline (have a pH above 7). This is based on the idea that acidic foods can lead to disease.

Proponents of the alkaline diet believe that eating a diet rich in acidic foods might disrupt the pH of the bloodstream, because the body's normal pH is slightly alkaline.

People use the alkaline diet for aging, athletic performance, breast cancer, heart disease, diabetes, high cholesterol, high blood pressure, obesity, and many other purposes, but there is no good scientific evidence to support these uses.
The alkaline diet is possibly safe for most people. There's no reason to expect safety issues as long as nutritional needs are being met.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if the alkaline diet is safe to use while pregnant or breast-feeding. Avoid use unless under medical supervision.


There is interest in using the alkaline diet for a number of purposes, but there isn't enough reliable information to say whether it might be helpful.
