Good article that somewhat eludes to all those chasing diet trends (Paleo, low-carb, low fat, vegan, etc.). While there are benefits to each diet the overall, general human diet should be focused on real, whole food, not the elimination of any other types of foods. Paleo and low-carb diets are great for some individuals but the Mediterranean and a Whole Foods diet has been shows just as, if not more, effective in weight, heart, and health management. 

If you eat whole food sources with an emphasis on vegetables, fruits, nuts, legumes, whole grains, fish, chicken, and healthy fats you have nothing to worry about.
