People eating a diet that is largely plant based that of vegetarians and vegans are mostly in good physical health, and have clean uncongested systems due to the quick transit time of food through the Alimentary canal. Let's define 'total health'. Perhaps if we were just a physical body. But human beings are more than that.
Humans are whole people with a mind, body and soul.
So how do we acquire the 'total' health state. That tingling awareness of being alive, where the emotional and mental outlook mirrors the physical vitality. Total health is the ideal state of harmonious interaction between the physical body, emotional mind and spiritual soul. Vegetarians and vegans are on the first rung of the 'total' health ladder. Tests have proven time and time again that plantbased diets are the most nourishing and healthy to live on.
