How much protein is in 100g of blueberries?

According to USDA food data, 100 grams of raw blueberries contains roughly 0.7 grams of protein. That is less than 1 gram, so blueberries should be thought of as a fruit source of micronutrients and fiber, not a meaningful protein source.

For context, 100 grams is about 2/3 cup of fresh blueberries, though that can vary a bit by berry size and how tightly they are packed. If you eat a larger bowl, the protein increases only slightly because the protein density is so low.

What blueberries do contribute nutritionally

Blueberries are better known for their carbohydrate content, antioxidants, and fiber than for protein. A 100-gram serving typically provides around 57 calories, about 10 grams of carbohydrates, and around 2.4 grams of fiber, plus vitamin C and manganese.

That makes blueberries a nutrient-dense fruit for snacks, oatmeal, yogurt bowls, and smoothies. If you’re trying to build muscle or hit a higher protein target, though, blueberries should be one part of the meal rather than the main source of protein.

How blueberries compare with other foods

Compared with dairy, eggs, meat, soy, beans, or protein powders, blueberries provide very little protein. Even many nuts and seeds contain several times more protein per 100 grams than blueberries, although they are also much more calorie-dense.

If your goal is satiety, recovery after exercise, or muscle gain, pair blueberries with a protein-rich food: Greek yogurt, cottage cheese, skyr, protein milk, tofu, chia pudding, or a protein shake. That way you keep the flavor and antioxidants of the fruit while actually moving the meal toward a useful protein total.

How to use blueberries in a protein-focused diet

The easiest approach is to treat blueberries as a topping or mix-in. Add them to yogurt, oats, cottage cheese, or a smoothie made with milk or soy milk. In most cases, the fruit improves taste and fiber without adding many calories.

If you track your meals, it helps to think in portions. For example, 100g blueberries plus a high-protein base can make a balanced snack after a workout. Fitnit can also help with at-home training by counting reps and checking form, which can make it easier to match your nutrition to your training routine.

Tips

• Use blueberries as a topping, not your main protein source.
• Pair 100g blueberries with Greek yogurt or cottage cheese for a more balanced snack.
• If you blend blueberries into a smoothie, add milk, soy milk, yogurt, or protein powder to raise the protein total.
• Check labels or food databases if you need precise macros; berry size and product form can change the numbers slightly.
• For workout days, combine blueberries with a protein-rich meal after training instead of relying on fruit alone.
