As a diabetic, choosing the right kinds of potatoes can help manage blood sugar levels. Some potatoes are better options than others due to their carb content and effect on blood sugar.
What are the best potatoes for diabetics?
The best potatoes for diabetics are:
- Sweet potatoes
- Yukon Gold potatoes
- Red potatoes
- Russet potatoes
These potato varieties tend to have a lower glycemic index, meaning they do not spike blood sugar levels as dramatically. They also provide more fiber, vitamins, minerals and antioxidants.
Why are sweet potatoes a good option?
Sweet potatoes have a lower glycemic index than white potatoes. The glycemic index is a measure of how much a food raises blood sugar levels. Sweet potatoes have a glycemic index of 44-94, while regular russet potatoes have a glycemic index of 111.
The fiber in sweet potatoes also helps slow digestion and prevents blood sugar spikes. One medium baked sweet potato with skin provides about 4 grams of fiber.
Sweet potatoes also contain more vitamins and minerals than white potatoes, including:
- Vitamin A – Important for immune function and vision
- Vitamin C – An antioxidant that promotes skin health
- Potassium – Helps control blood pressure
- Manganese – Aids metabolism and bone health
The vibrant orange flesh of sweet potatoes provides antioxidants like beta-carotene as well. All of these nutrients can help manage diabetes complications.
Why choose Yukon Gold potatoes?
Like sweet potatoes, Yukon Gold potatoes have a lower glycemic index than russet potatoes. The glycemic index of Yukon Golds ranges from medium (56) to high (111) depending on cooking method. They also contain more fiber, with 2 grams per small potato.
Studies show the yellow flesh potatoes like Yukon Gold may help with blood sugar control. The pigments that give them their yellow color may inhibit an enzyme involved in breaking down starches into sugars.
Some key nutrients in Yukon Gold potatoes include:
- Vitamin C
- Potassium
- Magnesium
- Phosphorus
These nutrients support blood pressure, bone strength and nerve signaling.
Why choose red potatoes?
Red potatoes have a lower glycemic index than white potatoes, ranging from 56-89. They have a waxy, firm texture and contain more fiber. One medium red potato contains about 2 grams of fiber.
The skin of red potatoes provides insoluble fiber that slows digestion, preventing spikes in blood sugar. The flesh provides some soluble fiber that helps feed the good bacteria in your gut.
Some nutrients found in red potatoes include:
- Vitamin C
- Vitamin B6
- Potassium
- Magnesium
These nutrients support nerve signaling, blood pressure regulation, immune function and energy levels.
Why are russet potatoes a good choice?
While russet potatoes have a higher glycemic index than sweet potatoes or red potatoes, they are still a better option than white potatoes. Russets have a glycemic index of 111, compared to white potatoes which have a GI of 113.
Russet potatoes contain more fiber than white potatoes – 2 grams per small spud. The brown fibrous skin is full of insoluble fiber that slows digestion.
Some healthy nutrients found in russets:
- Vitamin C
- Potassium
- Magnesium
- Iron
Overall, russet potatoes make a healthier choice than white potatoes for diabetics due to their nutrition profile.
How do potatoes affect blood sugar?
Potatoes contain carbs, which can impact blood sugar levels. However, the glycemic index measures how dramatically different carbs influence blood sugar. Potatoes have a medium to high GI.
But the GI doesn’t tell the whole story. The quantity of carbs matters too. One medium potato contains:
- Russet: 37 grams carbs
- Red: 26 grams carbs
- Yukon Gold: 22 grams carbs
- Sweet Potato: 23 grams carbs
For comparison, one slice of white bread contains about 15 grams of carbs. Potatoes are relatively high carb vegetables.
The fiber, fat and acidity of a potato also affects its impact on blood sugar. Eating potatoes with the skins provides fiber that slows digestion and blunts blood sugar spikes.
How to minimize blood sugar spikes from potatoes
Here are some tips for managing your blood sugar when eating potatoes:
- Choose small or medium potatoes
- Keep the skin on for fiber
- Avoid fried or roasted potatoes
- Try less processed varieties like reds, Yukon Golds or sweet potatoes
- Pair potatoes with other foods like lean protein, veggies or beans
- Watch your portion sizes – 1⁄2 medium potato per meal
Following a low glycemic index diet can also promote steady blood sugar levels. Focus on nutrient-dense, high fiber carb sources like beans, lentils, vegetables, berries and whole grains.
Should diabetics avoid potatoes?
Most diabetics do not need to completely avoid potatoes. With careful selection and portion control, potatoes can be part of a healthy diabetes diet.
Focus on consuming potato varieties with a lower glycemic index like sweet potatoes, reds and Yukon Golds. Avoid large portions to limit carb intake. Also, do not make potatoes a staple side dish at every meal.
Prepare potatoes by baking, boiling or roasting instead of frying. Leave the nutritious skin on for added fiber. Pair potatoes with lean proteins or non-starchy vegetables at mealtimes.
Check your blood sugar regularly when adding potatoes to your diet. You may be able to tolerate 1⁄2 a medium sweet potato or red potato per meal without spiking levels too much.
Work with a registered dietitian knowledgeable in diabetes management. They can provide personalized potato recommendations based on your health goals, activity levels, BMI and blood sugar numbers.
Healthiest ways to prepare potatoes
To maximize the nutrition in potatoes, prepare them with minimal added fat, salt or calories:
- Bake – Poke holes to allow steam to escape and prevent bursting. Bake until easily pierced with a fork.
- Boil – Peel and chop potatoes into similar sized pieces, and boil until tender when pierced. Drain and lightly season.
- Steam – Cook potato with skin on in a steamer basket over boiling water until tender.
- Microwave – Poke skin with a fork, then microwave on high for 4-5 minutes per potato.
- Roast – Chop into wedges, lightly coat in oil, and roast at 400°F until browned and crispy.
- Mash – Peel and boil potatoes until tender, then mash with a small amount of milk and minimal butter.
Avoid preparing potatoes by deep frying, batter frying or loading them with high fat toppings like bacon, cheese and sour cream.

Should diabetics take any precautions with potatoes?
Diabetics should take some precautions around potato consumption:
- Test blood sugar before and 1-2 hours after eating potatoes to see individual response
- Take diabetes medication as prescribed to help manage carb absorption
- Carry quick-acting glucose tabs in case blood sugar drops too low
- Always have a source of protein and fat for balance when eating potatoes
- Avoid potatoes if managing kidney disease or digestive issues
- Be careful of potatoes cooked or processed with lots of fat, salt or sugar
It’s also important to work with your doctor to set carb limits at meals and speak with a dietitian about appropriate potato portion sizes. Monitor A1C levels to assess overall blood sugar management when following a diabetes diet that includes potatoes.
Comparison of nutrient content in potatoes
Here is a comparison of the nutrient content in a medium baked potato from various types:
| Russet | Red | Yukon Gold | Sweet Potato | |
|---|---|---|---|---|
| Calories | 161 | 132 | 145 | 103 |
| Net Carbs | 37g | 26g | 22g | 23g |
| Fiber | 2g | 2g | 2g | 4g |

| Vitamin C | 27% | 30% | 35% | 30% |
| Potassium | 26% | 27% | 24% | 15% |
As shown, sweet potatoes contain by far the most vitamin A. Red potatoes contain slightly more vitamin C and potassium than other varieties. Overall, Yukon Gold and red potatoes have the lowest carb content per serving.
The best potato choices for balanced blood sugar
In summary, the best potatoes for blood sugar balance in diabetics include:
- Sweet potatoes – Rich in antioxidants, vitamin A and fiber. Lower carb and glycemic index.
- Yukon Gold – Moderate carbs and GI. Contains vitamins and minerals for health.
- Red potatoes – Firm texture, fiber and nutrients. Lower carb impact.
- Russets – High fiber skin and moderate carb load. Cause less dramatic spikes than white potatoes.
Potatoes can fit into a diabetic diet with careful selection and portion control. Focus on healthier cooking methods and pair potatoes with proteins and non-starchy veggies. Check your blood sugar response and work with a dietitian when adding potatoes to your meal plan.
