When you have diabetes, it's vitally important to choose the right foods and eat a balanced diet to control your blood glucose levels. One of the foods that raises questions is sweet potatoes. A common question is whether sweet potatoes are good for diabetics. Below, we'll try to dispel that doubt. We'll tell you everything you need to know about their impact on diabetes and how to safely include them in your diet.
Is sweet potato good for diabetics?
Sweet potatoes, also known as yams, are a nutrient-dense tuber with a naturally sweet flavor. Unlike potatoes, they have a lower glycemic index (GI) , meaning they have a lower impact on blood sugar levels.
Some benefits of sweet potato for diabetics include:
-
Low glycemic index: Depending on the variety and cooking method, sweet potatoes can have a moderate to low GI.
-
High fiber content: Fiber helps slow the absorption of sugars and improves glycemic control.
-
Rich in antioxidants: Contains beta-carotenes and other antioxidant compounds beneficial for cardiovascular health.
-
Source of vitamins and minerals: Especially vitamin A, vitamin C, potassium and magnesium, which contribute to overall health.
How does sweet potato affect blood sugar levels?
The impact of sweet potatoes on blood glucose depends on several factors, such as the variety, the way they are cooked, and the amount consumed. Therefore, although they have a lower glycemic index than potatoes, their consumption should be moderate and well-planned as part of a balanced diet for people with diabetes.
Factors influencing the impact of sweet potato on glucose
-
Sweet potato variety: Some varieties contain more starch than others, which can influence the glycemic index.
-
Cooking method: Baking or boiling maintains a lower glycemic index compared to frying.
-
Amount consumed: A controlled portion is key to avoiding increases in glucose levels.
-
Pairing with other foods: Pairing it with proteins or healthy fats can help slow the absorption of sugars and improve glycemic control.
What varieties of sweet potato can you enjoy?
In case you didn't know, there is more than one type of sweet potato, each with unique nutritional properties that can be beneficial for people with diabetes. Below, we explain the characteristics and differences between the most common types of sweet potatoes:
-
Orange sweet potato : This is the most common variety and is notable for its high beta-carotene content, which is converted into vitamin A and supports eye health and the immune system. Its sweet flavor and creamy texture make it ideal for mashed potatoes or baked.
-
Purple sweet potato : Its intense color is due to its high anthocyanin content, powerful antioxidants that help reduce inflammation and improve cardiovascular health. Its earthy flavor and firm texture are the reason it's often used in salads or stews.
-
White sweet potato : It contains fewer natural sugars and a more neutral flavor, making it an excellent choice for those seeking a lower glycemic impact. It's rich in fiber and minerals like potassium and magnesium, which help regulate blood pressure.
-
Yellow sweet potato : Although less well-known, this variety is rich in antioxidants and has a slightly sweet flavor with nutty notes. Its texture, somewhere between creamy and firm, makes it versatile for a variety of culinary preparations.
Healthy ways to eat sweet potatoes if you have diabetes

Dairy-Free Mashed Sweet Potatoes : Mash boiled sweet potatoes and mix them with a little coconut oil or almond milk for a healthier option compared to traditional mashed potatoes.
