Do you have potato-blood? I hope not because that would mean that you are terribly ill. It’s an old expression, apparently. But I digress; are potatoes really that unhealthy to eat? And do they fit in with a paleo diet?

If you read a lot of Paleo blogs, I'm sure you’ll have noticed that opinions vary significantly… here are some of the viewpoints…

Paleolithic or a bit younger?

Potatoes are a contentious subject when it comes to the paleo diet. Strictly speaking they don’t fit the bill, at least not at first sight. Cultivation of vegetables started the Neolithic era, and consuming potatoes is most likely developed during this period, not before. Raw potatoes are not the most delicious food you've ever had; you need to cook them before they become more edible (although some people do eat them raw, it’s not advisable).

A potato is also a ‘nightshade’, which would not have come into existence before the Neolithic period, like tomatoes and eggplant. Paleolithic people would not have eaten them, simply because they were not around. But we can’t be sure about this. And anyway – Paleo is a science – not a re-enactment, after all!

The fact that some people are not able to fully digest a potato, can lead to the theory that we never adapted to these foods, and therefore, are not supposed to eat them.  The paleo theory that some people follow “if you can’t eat it raw, it’s not paleo” seems to be valid here. Whilst regular potatoes and white potatoes are not edible in their raw forms, sweet potatoes are (but again, I wouldn't advise it!)

Potatoes and your health

Potatoes consist mainly of starch, which isn't very good for people that are insulin resistant. Although they are a ‘pure food’, it needs to be cooked to become edible. Further processing is not necessary, as it would be in the case of grains (a much easier to define Paleo no-no).

Potatoes are 100% carbohydrate. This will increase your insulin, which is fine for some people. Athletes and those who train hard are often able to eat potatoes almost every day and have no problems with them. Potatoes are a very healthy source of carbs to refill and refuel your body (especially compared to grains and other refined carbs for example). So, it completely depends on you; but if you’re overweight, already insulin resistant, and your body isn't good in coping with glucose – then I’d leave the potatoes alone.

Personal choice

Whether or not you think that you should, or should not, include potatoes into your diet is completely up to you. It is very likely that the Paleolithic humans did eat raw potatoes.

If you are already overweight, it is probably best to avoid them. Because they are so carb heavy, it’s better to leave them alone and replace them with other paleo foods that are just as nutritious, but with less carbs.

If you are sensitive to nightshades, be careful. Nightshades can cause serious bowel and digestive problems to people who are sensitive.

Potato Considerations

Should you consider to have potatoes in your diet, you might like to consider the points below:

1. Peel the potato! Most of the toxins are located in the skin. Removing the skin, removes the risk
2. Buy organic potatoes. Potatoes have the tendency to suck up the toxins from the ground. Since the modern human uses toxins to make foods grown, it’s better to buy organic potatoes that are not drenched in them.
3. Green potatoes are bad. They contain saponins, which are toxic. Don’t eat the green ones!
4. Potatoes break down to glucose. When you are trying to lose weight, potatoes are definitely banned from the menu.

Sweet Potatoes vs White Potatoes

One of the most common questions in the Paleo world is whether sweet potatoes are a better option than white potatoes. Nutritionally, both offer benefits, but they serve slightly different purposes depending on your health goals and individual tolerance.

Sweet potatoes are generally accepted across most Paleo frameworks. They’re rich in beta-carotene (which the body converts to vitamin A), and tend to have a gentler impact on blood sugar levels. For this reason, they’re often the go-to choice for people looking to support stable energy levels while still enjoying a satisfying, starchy vegetable.

White potatoes, on the other hand, have a higher glycaemic index, meaning they raise blood glucose more rapidly. While this isn't inherently “bad,” it’s something to be aware of, especially if you’re managing insulin resistance or trying to lose weight.

If you’re not dealing with any specific health concerns, white potatoes in moderation can be perfectly fine. But for those in the early stages of a weight loss journey or with autoimmune sensitivities, sweet potatoes may be the safer and more nutrient-dense choice.

Preparation Methods Matter

Not all potato dishes are created equal. How you prepare potatoes can significantly affect their health impact. Boiling or roasting potatoes (especially after peeling and choosing organic) is a far cry from deep frying them in seed oils or serving them smothered in sour cream and cheese.

Interestingly, cooking and then cooling potatoes forms resistant starch — a type of carbohydrate that resists digestion and acts more like fibre. Resistant starch can feed beneficial gut bacteria and may even help regulate blood sugar. So, if you’re going to include potatoes, enjoying them cold in a homemade potato salad with olive oil, herbs and vinegar can actually offer additional benefits.

Avoid heavily processed forms like crisps, fries from fast food chains, or any dish made with industrial oils. These options introduce inflammatory fats and additives that move your meal firmly away from the real food philosophy of Paleo.

Potatoes in an Active Lifestyle

For those who engage in high-intensity workouts, weightlifting, or endurance sports, starchy carbohydrates like potatoes can be incredibly useful for replenishing glycogen stores. The key here is timing and portion control.

Post-workout meals that include clean, fast-digesting carbs like potatoes (paired with protein) can enhance recovery and support muscle growth. This is especially helpful for Paleo athletes or CrossFitters following a cyclical low-carb or targeted ketogenic approach. Just be sure to keep an eye on how your body responds — we’re all biochemically unique.

Non-Potato Paleo Carb Alternatives

If you’re trying to reduce your intake of potatoes, there are plenty of fantastic Paleo-friendly alternatives that won’t spike your blood sugar or aggravate nightshade sensitivity. Here are a few options:

• Cauliflower: Mashed, riced or roasted, this versatile veg is low in carbs and high in fibre.
• Butternut pumpkin: Slightly sweet and rich in vitamins, it works well roasted or mashed.
• Parsnips: A root vegetable with a slightly nutty flavour that roasts beautifully.
• Turnips: Lower in carbs and with a unique taste, turnips are great in soups or stews.
• Carrots: Slightly higher in carbs, but packed with nutrients and suitable for roasting, mashing or spiralising.

These options offer variety while keeping you aligned with your Paleo goals. They also introduce different vitamins and minerals into your diet, which supports overall nutritional diversity.

When to Reintroduce Potatoes

If you're currently following a stricter Paleo protocol such as AIP (Autoimmune Protocol) or Whole30, potatoes are typically excluded. However, once you've eliminated potential problem foods and have a better understanding of how your body reacts, you can experiment with reintroducing them.

Start with small amounts of peeled, well-cooked organic white potatoes and monitor how you feel. Watch for any changes in digestion, energy levels, skin clarity, or joint discomfort. If no adverse effects occur, potatoes might just be a fine addition to your version of Paleo living — especially if you’re metabolically healthy and physically active.

The Takeaway on Potatoes and Paleo

At the end of the day, Paleo is not a rigid rulebook — it’s a framework for eating real, nutrient-dense foods that work for your body. While white potatoes may not be “strictly” Paleo, they can be a functional and enjoyable food choice for many people. It all depends on your health goals, activity level, metabolic condition, and personal preference.

Listen to your body, experiment mindfully, and stay open to adjusting your approach as you go. That’s what makes the Paleo lifestyle sustainable — and effective — in the long run.
