I’ve been on whole foods for the better part of 2005. Thus far I no longer have:
headaches
joint pain
brain ‘fog’
energy swings
allergies
digestive issues (I’ll spare details)
asthma (well, almost gone)
and on and on

The first two weeks were hard but after that, the body craves real food. Its smooth sailing from there on and once you alleviate some of your ailments, you have sustaining momentum. Food the way nature intended: unprocessed, uncooked, whole and organic!
