Technically, rice is a grain, which means it’s not strictly Paleo, but there’s more to the story.
One of the main reasons we avoid grains is because they tend to be high in carbohydrates and anti-nutrients. White rice is certainly high in carbs, but it is lacking most of the anti-nutrients that tend to cause problems. The carbs may still cause problems for some people, but for those who need a little more carbs in their diet, white rice can be a safe way to get those carbs.
The Difference Between Brown Rice and White Rice
The difference between brown rice and white rice is that white rice has been stripped of the bran, and brown rice still has the bran on it. Brown rice contains more vitamins than white rice and also more fiber, which can be considered good things. The vitamins come at a price, however, because the bran is where the phytonutrients are located.
