Breakdown of Macronutrients in 60g of Blueberries
A 60-gram serving of fresh or frozen blueberries is a low-calorie, nutrient-dense snack. While the exact values can vary slightly depending on whether they are cultivated or wild, and fresh or frozen, the general nutritional profile remains excellent. This portion size is rich in carbohydrates, mainly simple sugars, but also includes a healthy dose of fiber.
Calories, Carbs, and Fiber
- Calories: Around 31-34 calories for 60 grams, making them a low-impact food on daily energy intake.
- Carbohydrates: Provides approximately 7-8 grams of carbohydrates, which are the body's primary energy source.
- Fiber: Contains roughly 1.4 to 3 grams of dietary fiber, crucial for digestive health and helping you feel full. Wild blueberries tend to have slightly more fiber than cultivated ones.
- Sugar: The sugar content is generally low, around 5-6 grams, mostly from natural glucose and fructose.
- Protein and Fat: Both are found in negligible amounts, with about 0.3-0.4 grams of protein and less than 0.5 grams of fat.
Vitamins and Minerals in a 60g Serving
Blueberries may be small, but they pack a significant punch of micronutrients. A 60-gram portion contributes to your daily intake of several important vitamins and minerals.
Key Vitamin Contributions
- Vitamin C: An excellent source, providing about 4.8 to 5.8 mg per 60g (scaling from 100g data), which is essential for immune function and acts as a powerful antioxidant.
- Vitamin K: Blueberries are a good source of Vitamin K1, contributing about 11.6 to 15.4 µg per 60g (scaled from 100g data). Vitamin K is vital for blood clotting and bone health.
Important Mineral Contributions

- Other Minerals: Smaller amounts of potassium, copper, and iron are also present, which are important for overall health.
Antioxidants: The Powerhouse in Blueberries
One of the most celebrated aspects of blueberry nutrition is their high concentration of antioxidants. A 60-gram portion is filled with these protective compounds.
- Anthocyanins: This specific class of flavonoids gives blueberries their vibrant color and is responsible for many of their health benefits. Anthocyanins have been shown to combat oxidative stress and inflammation.
- Polyphenols: Blueberries contain various other polyphenols, including phenolic acids, which also contribute to their potent antioxidant activity.

Health Benefits of a Small Serving
Incorporating even a small, 60-gram serving of blueberries into your daily diet can contribute to several health improvements, thanks to its nutrient profile.
Supports Heart Health
The antioxidants, particularly anthocyanins, help protect against the oxidation of LDL cholesterol, a crucial step in heart disease development. Regular consumption may also help lower blood pressure.
Boosts Brain Function
Studies suggest that blueberries may help improve memory and cognitive function, especially in older adults. The antioxidants help combat oxidative stress and inflammation, which are known to contribute to age-related brain decline.
Aids Blood Sugar Management
Despite their sugar content, blueberries have a relatively low glycemic index. The bioactive compounds can help improve insulin sensitivity and glucose metabolism, making them a safe and healthy fruit for individuals with diabetes.
Promotes Digestive Health
The dietary fiber in blueberries helps prevent constipation and supports a healthy digestive system. Fiber also feeds the beneficial bacteria in your gut, contributing to overall gut health.
Anti-Inflammatory Effects
The antioxidants have been shown to have anti-inflammatory properties, which can help reduce chronic inflammation in the body. Chronic inflammation is a risk factor for various diseases.
