Calorie Breakdown for 28 Grams of Blueberries
The low-calorie nature of blueberries is one of their main attractions, particularly for those monitoring their energy intake. A 28-gram serving is roughly equivalent to about 20 small berries or a small handful. The energy content comes primarily from carbohydrates, specifically natural sugars, and dietary fiber. This macronutrient profile ensures that the calories are not "empty" but rather contribute to sustained energy and satiety. The breakdown for 28 grams is as follows: 91% carbohydrates, 5% fat, and 5% protein.
Nutritional Profile: What's Beyond the Calories?
While the calorie count is minimal, the nutritional benefits of 28 grams of blueberries are noteworthy. They are a good source of vitamins, particularly vitamin K, which is essential for bone health and blood clotting. The powerful antioxidants, such as anthocyanins, which give the berries their vibrant blue color, help protect the body against damage from free radicals and reduce inflammation. In addition, this small portion contains beneficial fiber that aids in digestion.
Comparison of Raw vs. Dried Blueberries
To understand the caloric difference, it's helpful to compare raw blueberries with their dried counterpart. The calorie density changes significantly due to the removal of water during the drying process.
| Feature | Raw Blueberries (approx. 28g) | Dried Blueberries (approx. 28g) |
|---|---|---|
| Calories | ~16 kcal | ~89 kcal (approx. 317 kcal per 100g) |
| Carbohydrates | ~4g | ~22g (approx. 80g per 100g) |
| Water Content | Very High (84%) | Very Low (15%) |
| Nutrient Density | Lower per gram due to water | Higher per gram due to water removal |
| Serving Size | Larger volume for same calories | Smaller volume for higher calories |
This comparison table highlights why it's crucial to be mindful of serving sizes when consuming dried fruits. While dried blueberries retain many of their nutrients, their concentrated sugar and calorie content can impact dietary goals differently than the fresh version.
