This section breaks down the macro and micronutrients found in this small but mighty serving.
Macronutrient Breakdown (per 100g raw sweet potato):

It also offers a dose of vitamin C, potassium, and manganese, among other nutrients.
Raw vs. Cooked: How Preparation Affects Nutrients
It's important to note that the nutritional information for raw sweet potatoes differs from their cooked counterparts. The method of cooking can alter the calorie count, glycemic index, and nutrient availability. For example, boiling can result in a lower glycemic index compared to baking or frying, which is beneficial for blood sugar regulation.
Comparison Table: Raw vs. Baked Sweet Potato (per 100g)
| Nutrient | Raw Sweet Potato (approx. 100g) | Baked Sweet Potato (approx. 100g) |
|---|---|---|
| Calories | ~86 kcal | ~90 kcal |
| Carbohydrates | ~20.1 g | ~20.7 g |
| Fiber | ~3 g | ~3.3 g |
| Sugar | ~4.2 g | ~8.4 g |
| Protein | ~1.6 g | ~2.0 g |

As the table shows, the calorie and carbohydrate content are fairly similar, but baking increases the sugar content. This is due to the process of cooking, which breaks down some of the starches into simple sugars.
The Health Benefits of Adding Sweet Potatoes to Your Diet
Incorporating sweet potatoes into your meals offers a multitude of health benefits beyond just the calorie count. These benefits include:
- Promoting Eye Health: The beta-carotene in sweet potatoes is converted into Vitamin A, which is essential for maintaining good vision, especially in low-light conditions.
- Supporting the Immune System: Vitamin A also plays a crucial role in maintaining a healthy immune system. Studies have shown a link between low vitamin A levels and reduced immunity.
- Improving Gut Health: The fiber content, which includes both soluble and insoluble types, is great for digestion. The antioxidants in purple sweet potatoes have also been shown to promote the growth of healthy gut bacteria.
- Providing Antioxidant Power: Sweet potatoes, particularly the orange and purple varieties, contain powerful antioxidants like beta-carotene and anthocyanins that protect the body from free radical damage linked to chronic diseases.
- Potential Cancer-Fighting Properties: Some studies suggest that the antioxidants in sweet potatoes may help protect against certain types of cancer.
Delicious Ways to Incorporate Sweet Potatoes
This versatile vegetable can be enjoyed in many forms, making it easy to add to your diet. Some popular methods include:
- Roasted: Cut into cubes and toss with olive oil and spices for a simple side dish.
- Fries: Cut into matchsticks and bake or air-fry for a healthier alternative to regular french fries.
- Mashed: Boil and mash with a touch of milk and spices for a creamy side.
- Baked: Bake whole in the oven until tender, then top with your favorite seasonings or healthy additions.
