What are Gold Sweet Potatoes?
Sweet potatoes are starchy root vegetables celebrated for their naturally sweet flavor and nutritional value. While the term "gold sweet potato" often refers to yellow or golden-fleshed varieties, their nutritional profile is largely similar to their more common orange counterparts, with some subtle differences in phytonutrient content. They are rich in beta-carotene, antioxidants, fiber, and essential minerals like potassium. The specific calorie count can change slightly based on the exact variety and how it's prepared, but the baseline for 100g remains consistent.
The Calorie Count: Raw vs. Cooked
The cooking process significantly impacts the final calorie density of a sweet potato. When you cook a sweet potato, moisture is lost, concentrating the nutrients and calories in the remaining mass. This is a crucial factor for anyone tracking their calorie intake.
Raw Gold Sweet Potatoes (100g):
- Calories: ~86 kcal
- Carbohydrates: ~20.1 g
- Fiber: ~3 g
- Sugar: ~4.2 g
- Protein: ~1.6 g
- Fat: ~0.1 g
Baked Gold Sweet Potatoes (100g):
- Calories: ~90 kcal
- Carbohydrates: ~21 g
- Fiber: ~3 g
- Sugar: ~6 g
- Protein: ~2 g
- Fat: ~0.1 g
Boiled Gold Sweet Potatoes (100g):
- Calories: ~76 kcal
- Carbohydrates: ~18 g
- Fiber: ~2 g
- Sugar: ~6 g
- Protein: ~1 g
- Fat: ~0.1 g
As seen, boiling reduces the caloric density per 100g due to water absorption, while baking concentrates it as water evaporates.
The Nutritional Powerhouse Behind the Calories
Beyond just the calorie count, the gold sweet potato offers a wealth of health benefits. They are an excellent source of beta-carotene, which your body converts to Vitamin A, essential for vision and immune function. Other key nutrients include Vitamin C, Vitamin B6, potassium, and manganese.
Key Nutrients in 100g (Raw) Gold Sweet Potatoes:
- Vitamin A: Over 100% of the recommended daily value in a baked sweet potato.
- Vitamin C: An important antioxidant.
- Potassium: Crucial for blood pressure regulation.
- Manganese: Plays a role in growth and metabolism.
- Dietary Fiber: Promotes digestive health and can help manage blood sugar.
Understanding the Glycemic Index
Sweet potatoes have a medium to high glycemic index (GI), but this can vary depending on the cooking method. Boiling, for example, is associated with a lower GI value compared to baking or roasting. This is important for those managing blood sugar levels.
Gold Sweet Potatoes vs. Orange Sweet Potatoes: A Comparison
While the caloric and basic macronutrient profiles are similar, the key difference lies in their phytonutrient composition.
| Feature | Gold Sweet Potato | Orange Sweet Potato |
|---|---|---|
| Appearance | Yellow or golden-colored flesh | Bright orange-colored flesh |
| Key Antioxidant | Carotenoids, including moderate beta-carotene | Very rich in beta-carotene |
| Vitamin A Content | Good source, but less than orange varieties | Excellent source, very high in beta-carotene |
| Flavor | Often milder and less sweet | Distinctly sweet, often with a richer flavor |
| Texture | Can be firmer and less moist | Typically moist and creamy when cooked |
How to Prepare Gold Sweet Potatoes for Calorie Control
Cooking methods can make a big difference in both the final calorie count and nutritional impact.
Boiling: For the lowest calorie-per-gram option, boiling is your best bet. Boiling sweet potatoes with the skin on and then peeling them can help retain more nutrients.
Baking/Roasting: While baking concentrates calories, it can also enhance the sweetness and flavor. To keep it healthy, avoid adding excessive oils or butter.
Steaming: A gentle cooking method that preserves nutrients and keeps the calorie count relatively low.
Mashing: When mashing, be mindful of what you add. Cream, butter, or extra sweeteners will significantly increase the calorie and fat content.

Conclusion
Ultimately, a 100g serving of raw gold sweet potatoes contains approximately 86 calories, a figure that shifts with cooking. By understanding how different preparation methods affect the calorie density, you can better control your intake while still enjoying the rich flavor and health benefits of this nutrient-packed root vegetable. Whether you prefer them boiled for a lower-calorie option or baked for a sweeter, more concentrated flavor, gold sweet potatoes are a fantastic and healthy choice for any meal.
Frequently Asked Questions
How does cooking affect the number of calories in sweet potatoes? Cooking alters the water content, which affects calorie density. Baking removes water, concentrating calories (around 90 kcal/100g), while boiling adds water, lowering the calories per 100g (around 76 kcal).
Are gold sweet potatoes healthier than orange sweet potatoes? Both are highly nutritious, but their phytonutrient profiles differ. Orange sweet potatoes have more beta-carotene, while the specific antioxidant content in gold varieties may vary slightly. The best choice is based on personal preference and dietary needs.
What are the main nutrients in a gold sweet potato? Gold sweet potatoes are packed with beta-carotene (which converts to Vitamin A), Vitamin C, B6, potassium, and dietary fiber.
Is it better to eat sweet potato with or without the skin? The skin of a sweet potato is rich in fiber and nutrients. Leaving the skin on, especially when baking, boosts the overall nutritional content of your meal.
Do sweet potatoes have a high glycemic index? Sweet potatoes have a medium to high glycemic index, which can be influenced by how they are cooked. Boiling tends to result in a lower GI value compared to baking or roasting.
Can sweet potatoes be part of a weight-loss diet? Yes, their high fiber content helps promote feelings of fullness. Choosing to boil them can also help manage calorie intake per serving.
How can I prepare sweet potatoes to keep the calories low? To keep calories low, opt for boiling or steaming instead of baking with added fats. Avoid heavy toppings like butter, cream, or brown sugar.
