The Macronutrient Breakdown of 40 Blueberries

When evaluating the nutritional profile of any food, the macronutrient breakdown provides the foundation. For a serving of about 40 raw blueberries (or approximately 40 grams), the numbers are surprisingly lean yet effective. This makes them an ideal snack for those monitoring their calorie intake while still seeking a satisfying and healthy treat.

  • Calories: 31 calories. This low number is one of the main attractions for health-conscious individuals.
  • Carbohydrates: 8 grams. A majority of this comes from natural sugars, specifically fructose and glucose, providing a quick source of energy.
  • Dietary Fiber: 1 gram. While a small amount, this contributes to digestive health and helps promote a feeling of fullness.
  • Total Sugars: 5 grams. These are naturally occurring sugars and are not comparable to added sugars found in processed foods.
  • Fat: 0.2 grams. Blueberries are naturally very low in fat.
  • Protein: 0.4 grams. The protein content is minimal, as is common with most fruits.

These values illustrate that a small handful of blueberries offers a balanced, low-impact source of energy without contributing significant calories or fats.

Vitamins and Minerals in Your Handful

Beyond the basic macros, the real value of blueberries lies in their rich micronutrient profile. Forty berries deliver a considerable dose of essential vitamins and minerals that play a crucial role in bodily functions.

  • Vitamin C (5mg): This powerful antioxidant supports the immune system, promotes healthy skin through collagen production, and helps protect cells from damage.
  • Vitamin K (10mcg): Essential for blood clotting and bone health, 40 blueberries provide a good portion of your daily recommended intake.
  • Manganese (0.2mg): This trace mineral supports bone formation and metabolism.
  • Potassium (42mg): An important electrolyte that helps regulate blood pressure and nerve function.
  • Other Trace Minerals: Include smaller amounts of magnesium, phosphorus, and iron.

The Power of Anthocyanins

The vibrant blue-purple color of blueberries is not just for aesthetics; it comes from potent antioxidants called anthocyanins. These flavonoids are key to many of the fruit's well-researched health benefits.

Anthocyanins and other antioxidants in blueberries help combat oxidative stress, which is damage caused by unstable molecules known as free radicals. By neutralizing these free radicals, blueberries may protect against chronic diseases, premature aging, and cellular damage.

Significant Health Benefits of Regular Blueberry Consumption

Incorporating blueberries into your regular diet can offer a wide array of health advantages, backed by scientific research.

  • Improves Heart Health: Regular consumption is linked to lower blood pressure and improved vascular function, reducing the risk of heart disease.
  • Supports Cognitive Function: Studies have shown that the flavonoids in blueberries can enhance memory, attention, and processing speed, potentially slowing age-related cognitive decline.
  • Aids in Weight Management: Being low in calories and high in fiber and water, blueberries can help you feel full and satisfied, curbing cravings for less healthy options.
  • Boosts the Immune System: A good source of Vitamin C and other antioxidants, blueberries support immune health and help the body fight off infections.
  • Enhances Gut Health: The fiber and polyphenols act as prebiotics, feeding beneficial gut bacteria and supporting overall digestive health.
  • Contributes to Bone Strength: The presence of Vitamin K and other minerals like manganese and calcium helps maintain bone health.
