Macronutrient Breakdown of 35g Blueberries
A 35g portion of blueberries is primarily composed of carbohydrates and water, with a very low fat and protein content. This makes them an excellent choice for a light snack that provides energy without being heavy. For a standard 35g serving of raw blueberries, the macronutrient profile is quite balanced relative to its total caloric count.
- Carbohydrates: The majority of the energy comes from carbohydrates, with about 5g per 35g serving. Of this, roughly 1g is dietary fiber, and the remaining is natural sugar, predominantly glucose and fructose.
- Fat: This serving size contains a negligible amount of fat, typically less than 0.1g, making it a virtually fat-free food.
- Protein: Similarly, the protein content is very low, with about 0.3g in 35g of blueberries.
Vitamins and Minerals in a Small Serving
Even in a small 35g portion, blueberries contribute a meaningful amount of micronutrients that are crucial for overall health. While they won't meet all your daily requirements, they provide a valuable boost.
- Vitamin K: A 35g serving is a good source of vitamin K, which is essential for proper blood clotting and bone health.
- Vitamin C: This portion provides some vitamin C, a powerful antioxidant that supports the immune system and skin health.
- Manganese: Blueberries are particularly noted for their manganese content. A 35g serving offers a small percentage of the daily value for this mineral, which plays a role in bone formation and metabolism.
- Other Trace Minerals: Smaller amounts of other minerals like potassium, copper, and magnesium are also present, contributing to various bodily functions.
The Power of Anthocyanin Antioxidants
The rich blue-purple color of blueberries is due to potent plant compounds called anthocyanins, a type of flavonoid antioxidant. These compounds are the primary reason blueberries are celebrated as a superfood, even in small doses. They work to neutralize free radicals in the body, which helps protect cells from damage and reduces oxidative stress.
The antioxidant benefits are linked to:
- Brain Health: Anthocyanins are known to cross the blood-brain barrier and can accumulate in areas of the brain that are important for memory and learning. Regular consumption may help slow age-related cognitive decline.
- Heart Health: The anti-inflammatory and antioxidant effects of anthocyanins can help reduce risk factors for cardiovascular disease, such as high blood pressure and cholesterol oxidation.
- Anti-Inflammatory Effects: By reducing oxidative stress, the compounds in blueberries can help combat chronic inflammation, a known contributor to many diseases.
Comparison Table: 35g Raw vs. 35g Frozen Blueberries
While fresh blueberries are often preferred for their texture, frozen berries offer a convenient and equally nutritious option. When comparing a 35g serving, the nutritional values are very similar, with only minor differences.

Conclusion
In conclusion, a 35g serving of blueberries offers significant nutritional benefits in a very low-calorie package. It provides a good source of vitamins K and C, and minerals like manganese, along with dietary fiber. However, the true value lies in the high concentration of anthocyanin antioxidants, which contribute to brain health, heart health, and reduced inflammation. Both fresh and frozen options offer comparable nutritional profiles, making them an accessible and simple addition to a healthy diet.
