We all have more than thousands of enzymes in our body which tend to fall short as we grow age, the more the enzymes used by the body, the more it affect/reduce our life span(shelflife). Digestive enzymes is a kind of enzymes used in digestion process, junk food(food that has low nutritional value with high fat contents),and processed food tend to requires large amount of enzymes during digestion, little enzymes are require to breakdown (digest)raw food(which are eaten as staple food by our forefathers making them to last longer.Am not condeming processed food, when you overconsume or underconsume, it can result to deficiency symptoms. Moderacy is require not only what we eat, what we do. Thanks
