A Detailed Look at the Calories in 75 Grams of Blueberries
When managing your daily calorie intake, understanding the nutritional value of your food is essential. A 75-gram serving of fresh blueberries is a light, healthy snack, or a vibrant addition to a meal. This amount, which is approximately half a cup, offers a small number of calories packed with beneficial nutrients. The primary sources of these calories are natural sugars, as blueberries are very low in fat and contain a minimal amount of protein.
Nutritional Breakdown of 75g Blueberries
Beyond their calorie count, blueberries are a nutritional powerhouse. For a 75-gram serving, the composition is overwhelmingly water and carbohydrates. The macronutrient breakdown is crucial for anyone monitoring their intake for health reasons or weight management. Here is a more detailed look at what this small handful of berries provides.
Macronutrients
- Carbohydrates: The majority of the calories in blueberries come from carbohydrates. A 75-gram serving typically contains around 11 grams of total carbohydrates, with a portion of that being dietary fiber. This provides energy and aids in digestive health.
- Fiber: This serving size offers approximately 2 grams of dietary fiber. Fiber is vital for maintaining a healthy digestive system and can contribute to a feeling of fullness, which is beneficial for weight management.
- Sugars: Within the carbohydrate count, there are about 7 grams of natural sugars, including fructose and glucose. These sugars give blueberries their sweet taste but are balanced by the fiber content, which helps manage their impact on blood sugar levels.
- Protein: Blueberries are not a significant source of protein, with about 1 gram in a 75-gram serving.
- Fat: The fat content is almost negligible, typically less than 0.5 grams per 75-gram portion.
Micronutrients and Antioxidants
In addition to their macronutrients, blueberries are renowned for their high concentration of vitamins, minerals, and antioxidants.
- Vitamin C: This powerful antioxidant supports immune function and promotes healthy skin.
- Vitamin K: Essential for blood clotting and bone health, vitamin K is another key nutrient found in blueberries.
- Manganese: This mineral plays a role in bone development and nutrient metabolism.
- Anthocyanins: These are the flavonoid compounds that give blueberries their characteristic deep blue and purple color. They are potent antioxidants with anti-inflammatory effects that protect cells from damage caused by free radicals.
