The Ancient holistic models of health ask us to be truly aware that all health conditions stem from our inability to digest food and life well. Traditional Indian medicine, Ayurveda, stipulates that our digestion be perfect so that we can function in a healthy way, both mentally and physically.
Being very mindful of what we eat, and how we eat it is also of extreme importance. This really involves knowing your own personal constitution and the elements (fire, earth, air, ether, water) that constitute your own form. In knowing this you can make wise food choices to suit your body.
