These easily assimilated foods are not like taking man-made vitamins, which can act like drugs and throw off your body chemistry. To enhance proper digestion, especially if you're not eating enough fresh produce, I suggest supplementing you diet with pro-biotic friendly bacteria cultures such as acidophilus, bifidus, as well as plant enzymes and perhaps Swedish bitters. This will help bring the intestinal flora into a healthy balance. It is important to take in enough fluids, because you may be dehydrated without realizing it. Dehydration can be lead to fainting, low blood-pressure, and fatigue.
All bodily functions depend on sufficient water intake.
Drinking plenty of water and fluids is vital, as it enhances the efficiency of your organs. My advice for an optimal healthy flowing body is to keep it all very simple. Eat only pure, organic essential foods and eat only when you're truly hungry.
