Calories in Sweet Potatoes vs. Other Starchy Vegetables

Sweet potatoes contain moderate amounts of calories compared to other starchy vegetables. Here is a comparison of the calories in 100 grams of different cooked starchy vegetables:

Vegetable Calories per 100 grams
Sweet Potato 86
Russet Potato 93
Carrots 35
Corn 96
Plantain 122

As you can see, sweet potatoes contain fewer calories than plantains and corn, about the same as white potatoes, and more than carrots. Overall, sweet potatoes are a moderate calorie starchy vegetable.

Calorie Composition of Sweet Potatoes

The calories in sweet potatoes come mostly from carbohydrates. Here is the calorie composition of a medium white sweet potato:

Nutrient Amount Calories
Carbohydrates 20.1 grams 80
Protein 1.6 grams 6
Fat 0.1 grams 1
Total 86

As you can see, over 90% of the calories come from carbohydrates. Protein and fat make up just a small percentage of the total calories.

Calories from Nutrients in Sweet Potatoes

Here is a more detailed breakdown of where the calories come from in sweet potatoes:

– Starch: Most of the carbohydrates in sweet potatoes come from starch, which provides 70-80 calories per medium sweet potato. Starch is made up of long chains of glucose molecules bundled together.

– Fiber: Despite being a carbohydrate, fiber does not provide calories because it cannot be digested by the human body. A medium sweet potato has around 3 grams of fiber.

– Sugars: There is also some natural sugar in sweet potatoes, which accounts for around 8 calories. This includes small amounts of sucrose, glucose and fructose.

– Protein: Sweet potatoes contain a modest amount of protein, providing around 6 calories per medium potato.

– Fat: There is minimal fat in sweet potatoes, accounting for only 1 calorie per medium spud. What little fat exists is mostly polyunsaturated and monounsaturated fat.

So in summary, the majority of calories come from the starch, with smaller amounts from sugar and protein, and minimal calories from fat.

Factors that Affect Calorie Count

Several factors can alter the calorie content of sweet potatoes:

– Size: As shown earlier, larger sweet potatoes contain more calories than smaller ones. The bigger the spud, the more calories it will have.

– Cooking method: How the sweet potato is prepared impacts calories. Frying adds oil and significantly increases calories. Boiling, steaming, roasting or baking do not add extra calories.

– Added ingredients: Toppings like butter, brown sugar or marshmallows will increase the calories versus a plain baked sweet potato.

– Maturity: Young (new) sweet potatoes tend to have fewer calories than more mature potatoes later in the season.

– Variety: There are hundreds of sweet potato varieties with slight differences in nutrient content and calories. Some may be a bit higher or lower in calories than others.

So when estimating calories, be sure to account for these factors. A large, fried sweet potato with butter will contain far more calories than a small, boiled plain sweet potato.

Nutrition Benefits

Despite their calorie content, sweet potatoes are considered one of the healthiest starchy vegetables because they provide many beneficial nutrients:

– High fiber – helps digestion and heart health

– Vitamin A – important for immune function and vision

– Vitamin C – antioxidants that fight cellular damage

– Potassium – helps control blood pressure

– Manganese – aids metabolism and bone health

– Antioxidant carotenoids – reduces inflammation and disease risk

Pairing sweet potatoes with lower calorie foods like veggies or lean protein can help maximize nutritional benefit while controlling calorie intake.

Ways to Reduce Calories in Sweet Potatoes

If you are looking to reduce the number of calories you get from sweet potatoes, here are some tips:

– Choose small or medium potatoes – avoids the extra calories from larger sizes

– Remove skin before cooking – the skin contains around 5% of the total calories

– Bake, steam or boil – avoids extra calories from frying in oil

– Avoid added fat/sugar – butter, oil, marshmallows, brown sugar, etc. add calories

– Eat in moderation – be mindful of portion sizes, 1 medium potato is one serving

– Substitute with veggies – cauliflower or carrots have fewer calories than sweet potato

– Mix in with lower calorie ingredients – make stews, sautés or salads using lean protein and non-starchy veggies

Calorie Density

In addition to total calories, looking at calorie density can be useful:

Calorie Density = Calories per Gram of Food

Foods with higher calorie density provide more calories per bite. Sweet potatoes have a moderate calorie density:

– Sweet potato: 0.75 calories per gram
– Carrots: 0.4 calories per gram
– Baked potato: 1.0 calories per gram
– Bacon: 5.4 calories per gram

Choosing more foods with lower calorie density, like fruits, vegetables, lean proteins, allows you to eat a larger volume of food while consuming fewer calories.

Weight Loss

When trying to lose weight, paying attention to portion sizes of all foods, including sweet potatoes, is important:

– A medium sweet potato is one serving at 114 grams and 86 calories

– Measure portions to avoid overestimating which leads to excess calories

– Eat sweet potatoes as part of balanced meals with vegetables, lean proteins, healthy fats

– Choose nutritious, lower calorie ingredients like herbs or salsa for toppings

– Stay hydrated by drinking water with meals

– Slow down eating and savor each bite of sweet potato

– Stop eating when full or satisfied, not overstuffed

Making sweet potatoes part of an overall healthy diet can still allow for weight loss success. Just be mindful of portions and ingredients.

Blood Sugar Impact

Despite their carbohydrate content, sweet potatoes have less impact on blood sugar than many other starchy foods because:

– They are an excellent source of fiber, which slows digestion and starch absorption from the digestive tract.

– They have a lower glycemic index, meaning they are absorbed more slowly and cause a more gradual rise in blood sugar.

For people with diabetes or prediabetes, sweet potatoes are considered one of the healthier starch choices, as long as portions are controlled.

Conclusion

A medium white sweet potato weighing approximately 114 grams contains about 86 calories, with the majority coming from starch. Larger potatoes have more calories, while smaller ones have fewer. Other factors like cooking method, additions, maturity, and variety can also affect the calorie content.

While sweet potatoes are starchy vegetables with a moderate amount of calories, they offer excellent nutrition benefits and can be incorporated into a healthy diet by paying attention to portion sizes and preparation methods. Their fiber, vitamins, minerals and antioxidants make sweet potatoes a nutritious choice as part of an overall balanced meal plan.
