Good point Pam, I think we all need to remember that it's the dose that makes the poison. So in the end its all about sodium control, glucose control, cholesterol control etc. Because, all these are used by the body in one way or another. If we go too high in any it can be dangerous in some cases, but if we get rid of them completely we'd cease to function.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
