A detailed breakdown of 25 blueberries
While 25 blueberries is a small handful, they pack a significant nutritional punch. This small serving offers a mix of macronutrients and a range of beneficial micronutrients and antioxidants. To give context to the smaller portion, information is sometimes extrapolated from the more commonly cited 100-gram serving size (approximately 50-75 berries), with a 25-blueberry portion estimated at around 50 grams for relevant calculations.
Macronutrient profile
According to nutritional data, a specific count of 25 blueberries provides the following macronutrient values:
- Calories: 19 calories
- Carbohydrates: 5 grams
- Dietary Fiber: 1 gram
- Sugar: 3 grams
- Protein: 0 grams
- Fat: 0 grams
This profile highlights that blueberries are primarily a source of healthy carbohydrates, with fiber contributing to digestive health and promoting a feeling of fullness. Their low-calorie count makes them an excellent choice for a snack or dessert replacement. The low sugar content is also particularly beneficial for managing blood sugar levels compared to other fruits.
Vitamins and minerals
Even in a small serving, blueberries contribute a variety of essential vitamins and minerals. While the amounts are modest compared to the daily recommended intake, they add to a balanced diet.
- Vitamin K: An essential fat-soluble vitamin crucial for blood clotting and bone health. Based on 100g data, 25 berries (approx. 50g) would provide a decent fraction of your daily needs.
- Vitamin C: Known for its immune-boosting properties and role in skin health, vitamin C is a vital antioxidant. A handful of blueberries is a great way to top up your intake.
- Manganese: This mineral plays a key role in metabolism and promotes bone and muscle strength. Blueberries are a good source of manganese.
- Other Trace Minerals: Blueberries also contain smaller amounts of other important minerals, including potassium, magnesium, calcium, and phosphorus.
Antioxidant capacity
Blueberries are renowned for their high antioxidant levels, primarily from compounds called anthocyanins, which are responsible for their characteristic deep blue color.
- Fighting Oxidative Stress: Antioxidants help combat oxidative stress, an imbalance between unstable free radicals and antioxidants that can damage cells and lead to chronic diseases.
- Anti-inflammatory Effects: The potent antioxidants in blueberries have significant anti-inflammatory properties, which can help mitigate inflammatory responses in the body.
- Brain Health: Studies suggest that the flavonoids in blueberries can have neuroprotective effects, potentially improving memory and cognitive function.
