Let food be thy medicine, and medicine be thy food. This quote from Hippocrates is the first line in “Practical Paleo” and provides the backbone for the 415-page tome by Diane Sanfilippo, a certified nutrition consultant who specializes in ancestral nutrition — based on diets before processed foods. Unlike diet books that promise quick weight loss and six-pack abs, “Practical Paleo” focuses on nourishment.
