Now don't get me wrong, soybean oil is not bad for your skin but it just doesn't stand out on your label as one of those great skin care oils like sweet almond oil or avocado oil does. Some people consider it to be a skin care neutral because it does not offer any benefits or detriments.
In general, eating Paleo means eating veggies, fruits, meats, fish, certain fats, nuts, and seeds. And it means removing grains (breads, pastas, rice, etc), beans, soy, dairy, certain vegetable oils, and refined sugar from your diet.
Taking front and center of the Paleo controversy is whether you should even be eating things like wheat, rice or corn, let alone making them the base of your food pyramid. Paleo advocates will point out that grains are not only difficult for humans to digest in their raw states, but they can actually be quite toxic.
