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.
While bacon, eggs and steak are the hallmark of today's Paleo diet, the real cavemen and women of the past didn't have the option to carefully measure the ratios of protein to fat to carbs -- they just needed to eat.
