Potato chips are a beloved crunchy snack, but their refined carbs, unhealthy fats, and high sodium content can spell trouble for blood sugar and metabolic health. This is especially concerning for those at risk of diabetes or managing it. The good news: you don’t have to give up satisfying snacks. By choosing healthier alternatives available in stores – from veggie chips to whole-grain and nut-based snacks – you can satisfy your crunch cravings and support steadier blood sugar levels. In this article, we’ll compare traditional potato chips with smarter options, include expert dietitian insights, and highlight how these swaps can help reduce the risk of diabetes.
The Problem with Potato Chips
Traditional potato chips might hit the spot taste-wise, but nutritionally they pose several concerns. Potatoes themselves aren’t “bad” – they actually contain nutrients like potassium – but frying them in oil transforms them into a high-fat, high-carb snack. “The problem comes when you start to fry things. Then you’re adding fat plus carbohydrates — which is a recipe for diabetes,” warns wellness coach Jacob Zemer.
- Refined Carbohydrates: Potato chips are made from starchy potatoes (often peeled, removing fiber) that are quickly digestible. A one-ounce (28g) serving of plain chips contains roughly 15 grams of carbs with only about 1 gram of fiber, meaning most of those carbs are refined starch. These refined carbs are broken down into glucose rapidly, causing quick blood sugar spikes. In fact, research links “eating unhealthy potato foods, such as chips and french fries,” with an increased risk of type 2 diabetes and its complications.
- Glycemic Index and Load: You might be surprised that due to their fat content, potato chips have a moderate glycemic index (GI) (reported around 56–70) – similar to green peas and lower than oatmeal in some cases. However, a lower GI doesn’t make them healthy. As registered dietitian Nancy Mazarin explains, “the fact that a food has a low glycemic index doesn’t mean it’s healthy (e.g., potato chips have a lower glycemic index than oatmeal…). But oatmeal and green peas have more nutrients.” In other words, chips provide plenty of empty carbs and calories without the fiber, vitamins, and mineral benefits that healthier carbs do.
- Unhealthy Fats: Chips are typically deep-fried in oils, which means a single ounce can pack around 10 grams of fat or more. Often a couple of those grams are saturated fat. Dietitians caution that fried potatoes and chips contain high amounts of unhealthy fats that may increase blood pressure, lower “good” HDL cholesterol, and lead to weight gain and obesity. These effects are especially dangerous for people concerned about diabetes, who often already face higher heart disease risk. In fact, one large study found that regular consumption of fried potatoes (like chips or fries) was associated with a significantly higher risk of developing type 2 diabetes. The calorie density of chips (about 150 calories per ounce) also contributes to weight gain if eaten in excess, which in turn worsens insulin resistance.
- Sodium Overload: Munching on chips also means taking in a hefty dose of salt. A standard serving of salted potato chips has around 150–200 mg of sodium. Eating several servings can quickly approach a substantial portion of recommended daily sodium limits. High sodium intake can raise blood pressure – not ideal for metabolic health or cardiovascular health. As Elizabeth Caffrey, RDN, points out, “Highly processed snacks are often loaded with sodium, saturated fat and fast-acting carbohydrates that can cause rapid blood sugar spikes.”
Veggie Chips and Vegetable-Based Snacks
Kale Chips, Beet Chips, and Carrot Chips: Many brands now offer chips made from whole vegetables like kale, beets, carrots, zucchini, or parsnips. These veggies are sliced and baked or dehydrated (sometimes lightly tossed in heart-healthy oil) to achieve a chip-like crunch. The advantage is that you’re essentially eating a vegetable, so you get more nutrients. Replacing potato chips with non-starchy veggie chips can lower your overall carb intake and glycemic load, helping to keep blood sugar steadier. Just watch out for those that are heavily salted or fried – some packaged “veggie chips” might still have ~150 calories and 8+ grams of fat per serving. Check for fiber content – true veggie-based chips often have a couple grams of fiber per serving (aim for at least 2g fiber), which is more than most potato chips.
Roasted Seaweed Snacks: If you want the crunch and salt with virtually no carbs or fat, consider seaweed snacks. These paper-thin sheets of roasted seaweed (often nori) are crispy and savory, usually just lightly brushed with oil and salt. They are extremely low-calorie (a whole pack might be 25–50 calories) and since seaweed is mostly fiber and protein, they have almost zero carbohydrates. “Roasted seaweed snacks are nonperishable and satisfy that salty craving with almost no carbohydrates, which is great for people looking for wholesome snacks while monitoring blood sugar,” says registered dietitian Lauren Harris-Pincus, MS, RDN.
Fresh Veggies with Dips (Chip Alternatives): Another option is to swap the chip entirely for crisp fresh vegetables. Baby carrots, cucumber slices, bell pepper strips, or celery sticks can give you a satisfying crunch. They’re obviously very low in carbs and calories and high in fiber. On their own these aren’t store-“bought” chips, but they pair perfectly with healthy store-bought dips like hummus or salsa to satisfy the urge for a “chips and dip” experience. In fact, using raw veggies as dippers is a diabetes-friendly strategy: “Crunchy veggies like carrots, cucumber, and bell peppers pair beautifully with hummus for a satisfying snack,” notes Samantha Cassetty, RD, in her diabetes-friendly snack tips. The fiber and water in veggies fill you up, and you avoid the refined starch entirely.
Whole-Grain Snacks: Popcorn and Whole Grain Crackers
Air-Popped Popcorn: Popcorn might just be the MVP of healthy crunchy snacks. It’s actually a 100% whole grain (the popcorn kernel is a whole grain), and when prepared without lots of butter or sugar, it’s low in calories and high in fiber. “Popcorn is a whole grain that’s low in calories and rich in fiber, making it a wonderful snack for people with diabetes,” says Sophie Lauver, RDN, a diabetes care specialist. Glycemic index-wise, popcorn is around 55, which is considered a low-GI food that has a relatively mild effect on blood sugar. One cup of plain air-popped popcorn has only about 31 calories and 6g of carbs (with 1+ gram of fiber). That means you can have a generous 3-cup portion for roughly 100 calories and 18g carbs, delivering a nice fiber boost without spiking glucose. Compare that to just 15 chips which are about the same carbs but gone in a flash!
Whole-Grain Chips or Crackers: If you prefer something more substantial to dip or crunch, reach for whole-grain crackers or popped grain chips. For instance, look for crackers made from 100% whole wheat, brown rice, or seeds. Brands like Triscuit (made from whole wheat and salt only) or Mary’s Gone Crackers (made with brown rice, quinoa, flax, etc.) provide fiber and often some protein. Samantha Cassetty, RD, recommends crackers that list whole grains as the first ingredient, noting that the “natural, healthy ingredients make these among the best crackers for diabetics.” Whole grain or seed crackers typically contain more fiber (3+ grams per serving) which helps slow down carbohydrate absorption.
Baked vs. Fried Matters: Many whole-grain snacks are baked, which is an advantage. Choosing baked chips/crackers over fried saves a lot of fat. You still need to watch portion sizes and total carbs, but you won’t be ingesting all the oil that comes with fried snacks. As noted earlier, even potato chips when baked have a lower fat content – the same logic applies to pita chips or tortilla chips. So opt for baked whole-grain pita chips or bean chips (often labeled as such) to cut down on empty calories from fat.
Nut and Legume-Based Alternatives: Protein and Fiber Powerhouses
Nuts, seeds, and legumes (beans, chickpeas, lentils) can also satisfy crunchy snack cravings while delivering big benefits for blood sugar and metabolic health. These options are typically low in refined carbs and high in protein, healthy fats, and fiber – the exact opposite of a potato chip. This combo leads to a slow, steady release of energy and minimal impact on glucose levels. In fact, snacks rich in protein or fat barely budge blood sugar at all.
A Handful of Nuts: Swapping chips for a handful of nuts (like almonds, walnuts, pistachios, or cashews) is a simple trade that can make a big difference. Nuts are very low in carbohydrates – e.g. one ounce of almonds has only ~6g carbs, 3g of which are fiber – and rich in unsaturated (heart-healthy) fats and protein. That means they have a negligible glycemic impact. “Nuts can easily be thrown in a bag…and they also provide a great source of heart-healthy fats and protein, which can help keep you feeling full until your next meal,” explains registered dietitian Holly Klamer, RD.
Best nuts for snacking: Almonds, walnuts, pistachios, pecans, and peanuts (technically a legume) are all excellent. Each has a slightly different nutrient profile (walnuts, for instance, are high in omega-3 fats; almonds are high in vitamin E and magnesium). If sodium is a concern, choose unsalted or lightly salted varieties. Keep portion to about 1 ounce (a small handful or ~23 almonds) since nuts are calorie-dense. But even 1 ounce can pack 6+ grams of protein and 3+ grams of fiber.
Roasted Chickpeas and Bean Snacks: One of the trendiest chip alternatives are snacks made from pulses (beans, chickpeas, lentils). And they deserve the hype – they’re crunchy, tasty, and far more nutritious than potato chips. Roasted chickpeas are a prime example. You can find them packaged (often labeled as “Crunchy Chickpeas” or brands like Biena or The Good Bean), or you can roast your own. Either way, chickpeas are high in fiber and protein. A 1/4 cup serving of roasted chickpeas might have ~18g carbs, but with 5g fiber and 5–6g protein, the net impact on blood sugar is much gentler than 18g of pure starch would be. Samantha Cassetty, RD, notes that “crunchy roasted chickpeas are a fiber-rich, plant-based protein option” and an excellent choice for a diabetes-friendly crunchy snack.
Nut-Based Crackers: Another innovative category is crackers or crisps made from nuts and seeds (instead of grain). For example, almond flour crackers (like Simple Mills brand) or seed crackers (flax, chia, etc.). These typically are low-carb, high-fiber alternatives to traditional crackers. They can be pricey, but are great for blood sugar – some almond flour crackers have only 8–10g carbs per serving with 2–3g fiber and plenty of healthy fats, making them very low glycemic. As the Texas Diabetes Council recommends, “for those on a low carb diet, options like almond flour crackers offer a satisfying crunch without high carbohydrate content.”
Better Blood Sugar, Better Health
Choosing these healthier store-bought alternatives not only helps curb immediate blood sugar spikes, but also contributes to long-term health and reduced diabetes risk. Snacks may seem small, but they add up: research suggests about 20% of the calories Americans consume come from snacks, and unfortunately many popular choices (like chips, crackers, cookies) are ultra-processed foods linked to conditions like type 2 diabetes. By swapping in snacks that are higher in fiber, protein, and healthy fats, you are actively cutting down on those risk factors.
Dietitians emphasize that smart snacking can be part of a diabetes-prevention or management plan. “Sometimes, people think of snacks as an unhealthy thing, but [they] can be quite the opposite,” says Kelly Kennedy, RD. “Snacks provide another opportunity for nutrition, and with a small amount of carbohydrates (15 grams or less), [they] can help keep blood sugar levels steady throughout the day.” In practice, this means a snack could be an occasion to get more fiber (e.g. from whole grains or veggies) or more healthy fat (from nuts or seeds) that you might miss at meal times. All of the alternatives we discussed – veggie chips, popcorn, nuts, etc. – check those boxes. They turn snack time from a blood sugar landmine into a blood sugar friendly mini-meal.
Conclusion: Crunch Smarter for Diabetes Prevention
Reducing your risk of diabetes doesn’t mean swearing off snacking; it means snacking smarter. Traditional potato chips are a textbook example of what to avoid – a combination of quick-digesting starch, unhealthy fat, and salt that offers a “temporary reprieve” for cravings but at the cost of spiking blood sugar. By replacing the chip habit with healthier store-bought alternatives, you can still enjoy the crunch and flavor while doing your body a favor.
Whether you reach for a bag of air-popped popcorn, a pack of roasted seaweed, some nutty trail mix, or bean-based chips with hummus, you’ll be choosing snacks that nourish you and keep glucose levels on a more even keel. These options are packed with fiber, healthy fats, vitamins and minerals – “the best snacks to choose,” as dietitian Elizabeth Caffrey says, for anyone watching their blood sugar. They’ll help you stay full longer, avoid the energy slump, and keep your metabolism happier.
So next time you’re in the snack aisle, steer clear of the classic potato chips, and head to the sections with nuts, seeds, whole-grain crackers, or dried veggies. Your taste buds might love the change, and your body certainly will. With these healthy alternatives on hand, you can munch mindfully, knowing you’re crunching your way toward better health and lowering your diabetes risk one snack at a time.
