They contain carbohydrates, so portion size still matters, but they also provide fiber, which may help slow digestion.

How they're prepared also makes a difference.

For example:

• Boiled sweet potatoes generally have a lower glycemic impact than some other cooking methods.

• Large portions or sweet potato dishes loaded with sugar, marshmallows, or syrup can significantly increase sugar intake.

People with diabetes should focus on the overall balance of the meal, not just one ingredient.

4. The Cooking Method Changes Their Nutrition

The way you cook sweet potatoes can influence both their texture and nutritional characteristics.

Common methods include:

Steaming

Helps retain many nutrients while keeping the texture soft.

Baking

Enhances natural sweetness and creates a creamy interior.

Roasting

Produces a caramelized flavor with a crisp exterior.

Boiling

May reduce some water-soluble vitamins but can influence how the starch is digested.

Deep-frying, on the other hand, adds extra fat and calories and is generally less nutritious than baking or steaming.

5. Sweet Potatoes Are Rich in Antioxidants

Different-colored sweet potatoes contain different beneficial plant compounds.

Orange Sweet Potatoes

Rich in beta-carotene.
