Current reading: Eat to Live by Dr. Fuhrman.
I'm giving it a lot of thought. My first response is to increase the leafy greens and fruits in my diet while I reduce my reliance on breads and pasta.
Is it hard?
Yes and no.
The hard part is to stay conscious of what I'm eating. (a good idea any time:) )
The easy part:
not much preparation required. A lot of it is just wash, chop, eat:)
