Indeed, whether or not potatoes are paleo is a good question and can be confusing because some versions of paleo do allow them. For the official or strict version of the paleo diet, white potatoes are usually excluded, says Randy Evans, MS, R.D., and consultant of , a ready-to-eat meal delivery service, that specializes in paleo meals.
You may question why potatoes are restricted since theyre unprocessed. One rationale is that potatoes have a high glycemic indexmeaning they elevate blood sugar levelsrelative to their nutritional benefits, Evans explains. Other versions of paleo focus on real whole foods, so white potatoes can be eaten in moderation.
And the second reason is because no one knows whether potatoes existed during the time of hunter-gatherers potatoes, says , MS, R.D.
A paleolithic diet is based on the premise of foods that were eaten before agriculture. Since no one knows precisely when people first started eating potatoes, the answer of whether or not potatoes technically classify as paleo is unclear, Moretti says.
Now, what about on the front?
Sweet potatoes are the only potato that is considered paleo, explains Evans. Sweet potatoes have a much lower glycemic index so while they have a similar amount of carbohydrates, their impact on blood sugar and insulin is much lower, which is a goal of eating paleo.
Its interesting to note that white potatoes belong to the nightshade family, while sweet potatoes are considered part of the morning glory family.
In regards to their vitamin and mineral content, Evans stresses that white and sweet potatoes have similar nutritional profiles. On the one hand, sweet potatoes boast a much higher level of Vitamin A, along with a greater amount of Vitamin C, B6, and calcium.
White potatoes can have higher levels of potassium and both having similar levels for magnesium, he adds.
Moretti bolsters this perspective, commenting, Contrary to some people's beliefs, all potatoes are nutritious and packed with nutrients like potassium, vitamin B6, niacin, vitamin C, and fiber. Sweet potatoes are lower glycemic index than white or red potatoes, but this doesn't mean the latter two are bad foods.
At the end of the day, as Moretti stresses, what state youre eating that potato in is keyyou dont need us to tell you baked or boiled potatoes are healthier than or eating potatoes in chip form.
If you suffer from achy joints after eating a meal with potatoes, you might have a rare sensitivity: Some people are sensitive to white and red potatoes due to the fact that they are nightshade tubers, cautions Moretti.
