Dr. Berg explains how cruciferous vegetables detoxify the liver in phase I and II enzymatic biotransformation. This means your body has the ability to dismantle poisons into harmless water soluble particles.
However, constant exposure to poisons, chemicals, endocrine disruptors, even alcohol cause phase I to speed up, overwhelming phase II enzymes – this is where you get sick. Cruciferous vegetables and a concentrated cruciferous extract called DIM slows down phase I and balances our phase II, so you can detoxify normally. The enzymes involved are called cytochromone P450.
