Researchers as far back as the 1930's discovered that animals failed to reproduce properly in a few as three generations when they were given a diet of exclusively cooked foods. Many people today subsist on a diet of all cooked foods.
Most people eat far too many cooked and processed foods.
When you do eat cooked foods, eat simple meals and add some powered enzymes or capsules to the meal. Work to preserve your supply of enzymes. Use the supplemental enzymes 2-3 times per day to help rebuild depleted enzyme levles.
