Macronutrient Profile: Carbs, Fiber, and Protein
One of the most notable features of what is the nutritional value of 150 grams of boiled sweet potatoes is its macronutrient composition. A 150-gram serving is primarily composed of carbohydrates, with a small amount of protein and minimal fat.
- Carbohydrates: This serving provides approximately 27 grams of carbohydrates, which serve as the body's primary energy source. These aren't just empty calories; they include natural sugars and fiber, contributing to a balanced energy release.
- Dietary Fiber: With about 4 grams of dietary fiber per 150-gram serving, boiled sweet potatoes are excellent for digestive health. This fiber content helps promote regular bowel movements and can support a healthy gut microbiome.
- Protein: While not a significant source of protein, the 150-gram portion contains around 2 grams. This adds a small but useful amount of protein to a meal, especially when paired with other protein-rich foods.
- Fat: This serving contains only about 0.2 grams of fat, making it an ideal choice for low-fat diets. The virtually fat-free nature of boiled sweet potatoes, when prepared without added oils or butter, is a key health benefit.
Vitamin and Mineral Breakdown
Beyond the macronutrients, the micronutrient profile of a 150-gram serving is impressive. Boiling helps retain many of these vital nutrients.
- Vitamin A (from Beta-Carotene): A medium-sized boiled sweet potato can provide over 130% of the daily value for vitamin A. This is converted from beta-carotene by the body and is crucial for vision, immune function, and skin health.
- Vitamin C: This serving contains a healthy dose of Vitamin C, a powerful antioxidant that helps protect the body from free radical damage and supports immune health. Interestingly, cooking methods like boiling can actually increase vitamin C content.
- Potassium: Boiled sweet potatoes are a good source of potassium, which is vital for maintaining healthy blood pressure levels and proper muscle function.
- Manganese: This essential trace mineral is present in sweet potatoes and plays a role in bone health and metabolism.
- Other Nutrients: Lesser but still significant amounts of B vitamins (like B6), magnesium, and iron are also found in this nutritional root vegetable.
