I have been reading more and more about the Hunter and Gatherer Diet. This simply means limiting our diet to foods that Hunter and Gatherers would have eaten. Foods that occur naturally and were intended to be eaten. This means avoid foods pumped full of hormones, genetically modified foods, and processed foods. The main staples of this diet include: lean mean (grass fed lamb, turkey and chicken), fish (not bottom eaters such as shellfish), fresh fruits and veggies and raw nuts.
I do not know that I can eat this way 100% of the time right away, but my goal is 80% of the time for starters.
