A Detailed Look at Blackberries' Macro Profile
Blackberries are a nutrient-dense fruit packed with vitamins, minerals, and antioxidants, while remaining low in calories and fat. For those counting macronutrients, a 3 oz serving provides a favorable balance, with a strong emphasis on healthy, complex carbohydrates from dietary fiber.
The Macronutrient Breakdown for 3 oz
Based on USDA data, a 3 oz (approximately 85g) serving of fresh blackberries provides the following macronutrient profile:
- Total Calories: Approximately 53 kcal
- Total Carbohydrates: Approximately 11.7 grams
- Dietary Fiber: Approximately 6.5 grams
- Sugars: Approximately 5.9 grams
- Protein: Approximately 1.7 grams
- Total Fat: Approximately 0.6 grams
This breakdown shows that the majority of the calories in blackberries come from carbohydrates, and importantly, a significant portion of those carbs are from dietary fiber. The fruit is practically fat-free and provides a small but valuable amount of plant-based protein.
The Role of Each Macronutrient
Carbohydrates and Fiber
Carbohydrates are the body's primary source of energy, and in blackberries, they come with a powerful sidekick: fiber. The 6.5 grams of fiber in a 3 oz serving is particularly noteworthy. Fiber is a type of carbohydrate that the body cannot digest, and it offers several health benefits:
- Digestive Health: Both soluble and insoluble fibers are present. Insoluble fiber adds bulk to stool, promoting regularity and preventing constipation. Soluble fiber helps feed beneficial gut bacteria and can lower cholesterol levels.
- Blood Sugar Control: The high fiber content helps slow the absorption of sugar into the bloodstream, preventing sharp spikes in blood glucose levels. This makes blackberries a good option for individuals managing blood sugar.
- Satiety: Fiber adds volume to your food, which helps you feel fuller for longer. This can aid in weight management by reducing overall calorie intake.
Protein
While not a significant source of protein, the 1.7 grams in a 3 oz serving is a useful contribution, especially for a fruit. Fruits are not typically high in protein, and blackberries contain some essential and non-essential amino acids. Pairing blackberries with a protein source like Greek yogurt, nuts, or seeds can create a more balanced snack or meal.
Fats
Blackberries are exceptionally low in fat, with less than one gram per serving. What little fat they do contain is primarily in the form of healthy polyunsaturated and monounsaturated fats. The almost non-existent fat content makes them a great option for those looking to limit their fat intake while still getting essential nutrients.
Health Benefits Beyond the Macros
Beyond their basic macros, blackberries are loaded with micronutrients that contribute to overall health:
- Rich in Antioxidants: Blackberries are bursting with antioxidants, including anthocyanins, which give them their deep purple color. These compounds combat oxidative stress and inflammation, potentially reducing the risk of chronic diseases like heart disease and cancer.
- High in Vitamin C: A 3 oz serving provides a good dose of Vitamin C, a powerful antioxidant that boosts the immune system and supports skin health by promoting collagen production.
- Excellent Source of Vitamin K: Blackberries are rich in Vitamin K, which is essential for blood clotting and plays a crucial role in maintaining healthy bones.
- Good Source of Manganese: This mineral is important for bone development, a healthy metabolism, and the proper functioning of certain enzymes.
Comparison of Berries (per 3 oz serving)
To put the macros for blackberries into perspective, here is a comparison with other popular berries based on USDA data.
| Nutrient | Blackberries | Raspberries | Blueberries |
|---|---|---|---|
| Calories | ~53 kcal | ~44 kcal | ~48 kcal |
| Carbohydrates | ~11.7 g | ~10.1 g | ~12.3 g |
| Dietary Fiber | ~6.5 g | ~5.5 g | ~2.0 g |
| Protein | ~1.7 g | ~1.0 g | ~0.6 g |
| Fat | ~0.6 g | ~0.6 g | ~0.3 g |
| Sugar | ~5.9 g | ~6.0 g | ~10.5 g |
This table highlights that while all berries are healthy, blackberries are exceptionally high in dietary fiber compared to blueberries and offer more protein than both raspberries and blueberries. Blueberries, however, contain a higher sugar content per serving.
How to Incorporate Blackberries into Your Diet
The versatility of blackberries makes it easy to add them to your daily routine. Here are some simple and delicious ideas:
- Breakfast: Add fresh or frozen blackberries to oatmeal, yogurt, or cereal for a nutritional boost.

- Snack: Simply enjoy a cup of fresh blackberries on their own for a low-calorie, satisfying snack.
Conclusion
In summary, a 3 oz serving of blackberries offers a low-calorie, high-fiber, and nutrient-dense profile. With approximately 53 calories, 11.7g of carbohydrates (of which 6.5g is fiber), 1.7g of protein, and only 0.6g of fat, they are an excellent choice for anyone looking to add more vitamins, minerals, and antioxidants to their diet. Their high fiber content promotes digestive health and satiety, while their rich antioxidant profile provides numerous health benefits.
