Paleolithic diets: Should we eat like our ancestors?

PCC employee Janice Parker has eaten a whole-foods diet for many years, but 14 months ago she changed it in a way that led her to shed 30 pounds, feel less joint pain, sleep more soundly, have more energy, and, remarkably, control her diabetes without medication.

Her diet, recommended by her physician, now is based on grass-fed meat, fish, leafy greens and other vegetables, fruit, nuts and seeds.
