Potato Chips, Unsalted: A Glycemic Index Analysis
When it comes to snacking, potato chips are a popular choice for many people. Today, we’re examining unsalted potato chips and their glycemic impact, nutritional profile, and how they fit into a balanced diet.
Glycemic Index and Load of Unsalted Potato Chips
Our user-friendly app features a searchable database, meal planning tools, and personalized recommendations based on your health goals.
Unsalted potato chips have a Glycemic Index (GI) of 54, placing them in the medium GI range (55 or less is considered low, 56-69 medium, and 70+ high). This means they cause a moderate rise in blood sugar levels compared to pure glucose.
However, the Glycemic Load (GL) is 29.32, which is considered high. While the GI tells us how quickly a food raises blood sugar, the GL takes into account both the GI and the amount of carbohydrates in a serving. A GL above 20 is considered high, making unsalted potato chips a significant contributor to blood sugar elevation despite their medium GI.
Nutritional Profile (Per 100g Serving)
- Calories: 537
- Protein: 6.25g

- Total Carbohydrates: 59.7g
- Fiber: 5.4g
- Sugar: 0.19g

Understanding the Impact on Blood Sugar
What makes potato chips interesting from a glycemic perspective is their combination of carbohydrates and fat. The high fat content (30.3g per 100g) typically slows digestion, which can moderate blood sugar response. However, the significant amount of net carbs (54.3g) still contributes to a substantial glycemic load.
Dietary Fiber Content
With 5.4g of fiber per 100g serving, unsalted potato chips do provide some dietary fiber, which is beneficial for digestive health and can help slow the absorption of sugars. However, this fiber amount isn’t enough to significantly offset the high carbohydrate content when consumed in typical portions.
Who Should Be Cautious?
- People with diabetes or insulin resistance
- Those following a low-carb or ketogenic diet
- Individuals monitoring calorie intake for weight management
Healthier Alternatives
If you’re looking for snack options with a lower glycemic load, consider:
- Nuts and seeds
- Baked vegetable chips
- Air-popped popcorn
- Raw vegetables with dip
Bottom Line
While unsalted potato chips have a medium glycemic index of 54, their high carbohydrate content results in a high glycemic load of 29.32. Combined with their high calorie and fat content, they should be consumed in moderation, especially for those monitoring blood sugar levels or managing weight.
Remember, the unsalted variety eliminates sodium concerns, but the other nutritional factors remain important considerations when incorporating this popular snack into your diet.
