As a registered dietitian nutritionist, I am often asked if sweet potatoes are ok to eat. The short and easy answer is YES. I am a big sweet potato fan but personal preference aside, there are lots of reasons why you should include them regularly.

Are sweet potatoes healthy?

Sweet potatoes are a whole, natural food loaded with vitamins and minerals including beta carotene, vitamin C, and potassium. And indeed, they are healthy and can be included in a healthy and balanced diet.

Is a sweet potato a carb or a vegetable?

Sweet potatoes are both a vegetable and a carbohydrate. It is considered a starchy vegetable because it contains high amounts of starch or carbohydrate.

Are sweet potatoes good for diabetes?

Sweet potatoes are a starchy vegetable, meaning they contain a good amount of carbohydrates. More specifically, a medium-sized sweet potato contains about 27g of carbohydrate or about 2 carbohydrate servings. Sharing that if you’re a person with diabetes who is carbohydrate counting.

Sweet potatoes are also a good source of fiber. The fiber is, of course, great for digestive health but it also helps to make you feel full longer and digests slower – a win for people with and without diabetes!

It’s hard to discuss diabetes and food without the Glycemic Index.

The glycemic index (GI), or how fast or slow your blood sugar rises after a meal, of sweet potatoes, depends on the method that it’s cooked. The GI is an important factor to consider, especially for people with diabetes, and foods with a lower GI can help promote stable blood glucose levels which can be good for your health.

Boiling sweet potatoes helps lower the glycemic index while roasting and baking sweet potatoes pushes the number higher. That doesn’t mean you have to only eat boiled sweet potatoes. Eat them the way you most enjoy!

Are sweet potatoes good for weight loss?

Sweet potatoes, while a starchy vegetable, are a vegetable nonetheless. Meaning they should absolutely be included as part of a well-balanced and healthy diet. The fact that they are a higher carbohydrate food just means you’ll want to keep portion size in mind if weight loss is a goal.

Sweet potatoes are higher in carbohydrates which you may want to consider when thinking about portion sizes, for example, if you’re trying to lose weight. 

Sweet potatoes for breakfast?

Sweet potatoes are a great choice for breakfast, and it’s a delicious way to start getting vegetables first thing in the morning! The creamy texture lends well to being mixed into pancake or waffle batter. And their natural sweetness makes it a perfect pair with oatmeal. But they are also good just as is. Try a roasted sweet potato plain or with a drizzle of peanut butter or dice them up and serve with eggs for a filling sweet potato hash.

Can you eat the skin on a sweet potato?

Yes, you can eat the skin on a sweet potato. And you should! Just be sure to scrub it well before cooking. The skin contains extra fiber and minerals. Next time you have sweet potatoes try them with the skin on.

Try this: Dice the sweet potatoes into cubes, drizzle them with olive oil and sprinkle with salt and pepper. Roast them in the oven until fork-tender.  Enjoy as a side dish for breakfast or dinner, toss onto a fall salad, or add the roasted potatoes to black bean tacos.
