Enzymes are proteins that catalyze reactions with an organism. Even if you have the best nutritional plan around, and supplement your diet with a host of vitamin supplements, without enzymes, the vitamins will not be absorbed into your system. The best source of enzymes from your diet comes from raw food, eaten in its original state with no processing.
When we are young, our digestive enzymes function at their best by breaking down food into necessary proteins, fats, and carbohydrates, while also helping various metabolic functions in the body take place. Many studies have proven that these enzymes deteriorate as we age, typically around age 40, though food choices and lifestyles people live with today also promote the depletion of the number of enzymes much more rapidly. We’ve seen teenagers that have decreased enzyme production!
With low enzymes, even the healthiest foods are not effectively utilized by our bodies because they are not properly broken down. This lead to lack of absorption and then nutrient deficiency.
