A strict Paleo diet does not include beans. However, if the beans are soaked before cooking, they are much more digestible.  Dr. William Davis recommends eating beans in moderation because they promote good gut health. His recommendation is to limit the serving size to only 1/4 – 1/2 cup per meal. 
Rice is not included in a Paleo diet either. To be honest, I would love to completely eliminate all grains from our family table, but we aren’t there yet. For now, we are trying to gradually reduce the amount of grains eaten while increasing the amount of grass-fed meats and fresh vegetables.
The current goal is to aim for Dr. Davis’ recommendation of 15 net carbs per meal.
