Paleo is short for Paleolithic. The premise of a Paleo diet centers around the idea that our bodies have not adapted sufficiently to eating foods that were available to us 10,000 years ago. It is thought that more than 70% of food consumed today was never available in Paleolithic times. The advances in agriculture and mass food production have caused us to move away from eating real food, which is food meant to work with our bodies for optimal health. A Paleo diet involves eating meat and vegetables, nuts and seeds, little starch, some fruit and no sugar. This means no grains, legumes, dairy, alcohol, and staying away from all processed foods. The Paleo plan promotes eating as our hunter-gathers ancestors did.
