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.
A paleo diet, or paleolithic diet, is a modern diet designed to emulate the diet of wild animals and plants eaten by humans during the Paleolithic era, or as far as this is possible in relation to foods available today. It's also therefore sometimes called a Stone Age, hunter-gatherer, or caveman diet.
