are we really what we eat?

Yes!!! of course we are!  we are visually an expression of whats going on inside. You've only to look at teenage skin to see the hormonal turmoil within shown on the outside, and of course teenagers with a bad diet generally are spottier than those who eat veg and  ditch fizzy drinks.
With age its ever more important to support the outside by feeding the inside well...green, green, green all the way will provide antioxidants to fight free radicals..they destroy collagen and elastin (ageing) as well as keeping you kidneys from over working or the minerals from leaching from your body!! Think prevention and the cure will be yours.
