Alkaline Foods and Acidic Foods

Our diet today tends to contain too many acidic foods and not enough alkaline foods. This causes a number of health problems.

Learn more about your health and the impact of alkaline foods and acidic foods.

Measuring Food Levels

The pH scale measures how acidic or alkaline a substance is. The scale ranges from 1 to 14 with 1 being very acid, 7 neutral and 14 very alkaline. Our body works the best and is the healthiest when it is at the optimal pH level. According to Dr. Christopher Vesey, N.D. our optimal pH is slightly alkaline and about 7.39.

Even though it is best to eat more alkaline foods, it doesn't mean that all of the acidic should be avoided. Instead they should be eaten in balance. Dr. Christopher Vasey, N.D. recommends eating 75-80% alkaline and the rest acidic.

Below is a list of foods, from Dr. Vasey's book, "The Acid-Alkaline Diet for Optimum Health."
