Plenty has been written about the paleo diet in its many forms, so here I offer just a quick list of pros and cons. Pros: It recommends eliminating processed foods and simple sugars. Cons: The science is flawed and meat intake is not great for the environment. Nutritionally, it limits foods that promote good health, including legumes and whole grains.
Just One Thing to do: Instead of following a strict diet, include more fruits and vegetables in place of processed food. Try fruit and oatmeal for breakfast instead of poptarts, chicken caesar salad for lunch instead of a burger and fries, and fish with green beans for dinner instead of Hamburger Helper.
