Eat primarily foods that contain live enzymes, life force and nutrients. This is similar to the concept of plaque on your teeth except you get it over your entire digestive tract.

Most people today have an over acid body, primarily from a diet of acid-forming foods and stress.

Anytime the body drops from full vitality, weakened areas result. Stress alone may create the over acidity which leads to mucoid plaque.
