Calorie and Nutritional Comparison: The Basics
When comparing the calorie content of strawberries versus blueberries, the difference is noticeable, especially when looking at the same weight. A 100-gram serving of fresh strawberries contains about 32 calories, whereas the same amount of fresh blueberries has approximately 57 calories. This is because blueberries are more calorie-dense than strawberries. However, when considering standard serving sizes, a one-cup portion of strawberries (around 144g) has roughly 46-54 calories, while a one-cup portion of blueberries (around 148g) contains 84-96 calories. The difference stems largely from their distinct carbohydrate and water content. Strawberries are composed of about 91% water, contributing to their lower calorie count, while blueberries have a lower water content at about 84%.
Beyond Calories: A Look at Macronutrients
While calories are a key factor for many, a complete nutritional comparison reveals more about what each berry offers. Both are excellent sources of fiber, which is vital for digestive health and can aid in weight management by promoting feelings of fullness. However, the fiber content differs slightly. According to some sources, a cup of blueberries provides 4 grams of fiber, while a cup of strawberries offers 3 grams. The sugar content is also a notable difference. Blueberries contain more sugar per 100g (about 10g) than strawberries (about 5g). Both berries have minimal amounts of protein and fat.
A Deeper Dive into Vitamins and Antioxidants
Nutrient density is where both berries truly shine, though they specialize in different areas. Strawberries are a phenomenal source of vitamin C, providing more than 5 times the amount found in blueberries per 100g. This makes them excellent for immune function and fighting free radicals. On the other hand, blueberries are often lauded as "antioxidant superstars," particularly for their high concentration of anthocyanins. These compounds are responsible for their deep blue color and are linked to brain and heart health. Both berries contain other important vitamins and minerals:
- Strawberries are a great source of:
- Vitamin C
- Folate (Vitamin B9)
- Potassium
- Manganese
- Blueberries provide a good dose of:
- Vitamin K
- Vitamin C
- Manganese
- Anthocyanins
Health Benefits of Strawberries vs. Blueberries
The nutritional differences between strawberries and blueberries lead to unique health benefits. Incorporating a variety of fruits, including both berries, is the best approach for a well-rounded diet.
Health Benefits of Strawberries
- Immune system support: The high vitamin C content boosts immunity and helps fight oxidative stress.
- Heart health: Antioxidants like anthocyanins and flavonoids can help improve cholesterol levels and lower blood pressure.
- Digestive health: The fiber content aids in healthy digestion and promotes regularity.
- Brain function: Studies suggest that daily consumption can improve cognitive performance and memory.
Health Benefits of Blueberries
- Brain health: Antioxidants in blueberries can reduce oxidative stress in the brain and potentially improve memory and cognitive function, especially in older adults.
- Heart health: The antioxidants and fiber in blueberries support cardiovascular health by helping regulate blood pressure and cholesterol levels.
- Blood sugar regulation: Blueberries have a relatively low glycemic index, and bioactive compounds within them can help improve insulin sensitivity.
- High antioxidant capacity: Studies have shown blueberries to have a very high total antioxidant capacity, meaning a strong ability to neutralize free radicals.

Conclusion: Which Berry is Best for You?
The quick answer is that blueberries contain more calories per gram than strawberries, but the takeaway for your diet is far more nuanced. Both berries are fantastic for your health, offering a powerhouse of vitamins, fiber, and antioxidants for relatively few calories. If you are strictly counting calories, strawberries are the lower-calorie option per serving. If your goal is to maximize antioxidant intake for brain or heart health, blueberries hold a slight edge in total antioxidant capacity. For a vitamin C boost, strawberries are the clear winner. Ultimately, a balanced diet that includes a variety of fruits is the most beneficial approach. Mixing these two delicious berries in a salad, smoothie, or yogurt provides the best of both worlds, ensuring you get a broad spectrum of nutrients. A good rule of thumb is to enjoy them both for optimal health benefits.
