Potatoes are a dietary staple across the globe, but they often receive criticism for their potential to spike blood sugar levels. For people managing diabetes or prediabetes, this raises the question: What potato does not raise blood sugar? While potatoes typically contain a high amount of carbohydrates, certain types and preparation methods can significantly lower their glycemic impact. This article explores which potatoes are the most blood sugar-friendly and how to prepare them to improve glucose management.
Healthline explains that potatoes like the Carisma variety have a glycemic index (GI) as low as 53, making them an excellent choice for managing blood sugar. Similarly, EatingWell notes that boiled, roasted, or cooled potatoes work well in a balanced diet when paired with other low-GI foods.
Understanding Blood Sugar and Potatoes
To understand how potatoes affect blood sugar, you must first consider their carbohydrate content. The body quickly digests these carbohydrates, converting them into glucose. This process causes a rise in blood sugar levels, but the impact varies depending on the type of potato and how you prepare it.
Key Factors That Influence Blood Sugar Levels:
- Glycemic Index (GI): Measures how quickly a food raises blood glucose. High-GI foods lead to faster spikes.
- Glycemic Load (GL): Combines GI with portion size for a more accurate blood sugar impact.
- Resistant Starch: Some potatoes develop resistant starch when you cool them after cooking. This starch slows glucose release.
Low-Glycemic Potatoes: Best Options
Certain potato varieties naturally have a lower glycemic index, making them better for blood sugar control.
1. Carisma Potatoes
- GI: 53 (low).
- Carisma potatoes contain less starch, which helps prevent rapid glucose spikes.
- People with diabetes or prediabetes can benefit from choosing this variety.
2. Nicola Potatoes
- GI: Medium-low.
- These waxy potatoes contain lower starch levels and maintain a firm texture after cooking.
- Boiling or steaming them further reduces their glycemic impact.
3. Waxy Potatoes (e.g., Red, Fingerling)
- GI: Lower than starchy varieties.
- These potatoes digest more slowly, leading to steadier blood sugar levels.
Sweet Potatoes vs. Regular Potatoes
Many people consider sweet potatoes a healthier alternative to regular potatoes, but how do they compare?
- GI of Sweet Potatoes: 44-61, significantly lower than most regular potatoes.
- Nutritional Benefits: Sweet potatoes contain more fiber, antioxidants, and essential vitamins.
- Best Use: Boiled sweet potatoes have a lower GI compared to baked or fried versions.
When choosing between the two, sweet potatoes often win for blood sugar control and added nutrients.

How Preparation Methods Impact Blood Sugar
The way you cook potatoes can greatly influence their glycemic impact. To maintain stable blood sugar levels, consider the following:
- Boiling: Boiled potatoes retain more resistant starch than fried or roasted ones.
- Cooling: Cooling potatoes after cooking increases resistant starch, which slows digestion.
- Avoid Frying: Fried potatoes have a high GI because frying breaks down starches and adds fat.
Practical Tips for Including Potatoes in a Low-GI Diet
You can enjoy potatoes without spiking blood sugar levels by following these strategies:
- Control Portions: Limit servings to 1/2 to 1 cup to manage carbohydrate intake.
- Pair with Protein and Fiber: Add chicken, beans, or leafy greens to your meal to slow glucose absorption.
- Choose Low-GI Varieties: Opt for Carisma, Nicola, or red potatoes instead of high-starch options like Russet.
- Cook and Cool: Allow boiled potatoes to cool before eating to increase resistant starch.
FAQs About Potatoes and Blood Sugar
- What are the best potatoes for blood sugar control?
Carisma and Nicola potatoes, along with red or fingerling varieties, offer the best options. - Are sweet potatoes always better than regular potatoes?
Not always. Preparation and portion size play significant roles, but sweet potatoes generally have a lower GI. - How does resistant starch affect blood sugar?
Resistant starch slows digestion and leads to a steadier glucose release. - Should diabetics avoid potatoes altogether?
No, diabetics can include potatoes in moderation when following proper portion control and preparation methods.
Conclusion
so What Potato Does Not Raise Blood Sugar? Although potatoes often receive criticism for their impact on blood sugar, certain varieties like Carisma, Nicola, and red potatoes, along with sweet potatoes, provide better choices for glucose management. Additionally, preparation methods such as boiling and cooling can significantly reduce their glycemic impact. By practicing portion control and pairing potatoes with other low-GI foods, you can enjoy them as part of a healthy and balanced diet.
