While almost everyone can agree that plants are an important part of a Paleo lifestyle, roots, such as beets, can be a bit more controversial. They do tend to be higher in carbohydrates and, because of that, it might be advisable for some people to avoid, or limit their intake of, beets. However, beets are made of much more than just sugar. They fall in line with a Paleo way of eating because they are rich in nutrients like potassium, phosphorous and magnesium.
Paleo and Carbohydrates
Different people have different levels of tolerance for carbohydrates. If you are among those who need a higher level of carbohydrates, beets can be an excellent, healthy source for those carbs. If, on the other hand, you are attempting to get or stay in ketosis, you might want to avoid sweeter foods such as beets.
Despite their high carbohydrate content, beetroots carry the Paleo seal of approval and Mark Sisson has an entire post devoted to the health benefits of these roots.
