The strawberry, scientifically known as Fragaria × ananassa, is a popular fruit prized for its sweet flavor and impressive nutritional profile. As an excellent source of several vitamins, minerals, and beneficial plant compounds, it provides substantial health benefits beyond its delicious taste.
The Macronutrient Breakdown of a Strawberry
When examining the nutritional values of a strawberry, it's clear that this fruit is mostly composed of water and carbohydrates, with very low fat and protein content. This composition makes it a fantastic, low-calorie choice for a healthy snack.
- Low in Calories: A 100-gram serving of raw strawberries contains approximately 32 calories. A full cup (152g) has around 49 calories, offering a satisfying serving with minimal caloric intake.
- Carbohydrates: The majority of a strawberry's energy comes from its carbohydrates. A 100-gram serving contains about 7.7 grams of carbohydrates, mostly from simple sugars like fructose, glucose, and sucrose. Its low glycemic index (GI) of 40 means it does not cause significant blood sugar spikes.
- High in Fiber: Strawberries are a great source of dietary fiber, with about 2 grams per 100-gram serving. Fiber is crucial for digestive health, feeding beneficial gut bacteria, and promoting feelings of fullness.
- Minimal Fat and Protein: With only 0.3 grams of fat and 0.7 grams of protein per 100g, strawberries are virtually fat-free and not a significant source of protein.
A Closer Look at Vitamins and Minerals
Strawberries are a nutritional powerhouse, packing a significant amount of essential micronutrients into each bite. The following are some of the most notable vitamins and minerals found in this fruit.
- Vitamin C: Perhaps the most famous nutrient in strawberries, a single cup provides a substantial portion of the daily recommended intake. Vitamin C is a powerful antioxidant essential for immune function, skin health, and wound healing.
- Manganese: This trace element plays a crucial role in metabolism, growth, and development. Strawberries are a good source, contributing to many bodily functions.
- Folate (Vitamin B9): Vital for cell function and tissue growth, folate is particularly important for pregnant women and older adults. Strawberries provide a decent amount of this key B vitamin.
- Potassium: An important mineral for regulating blood pressure and overall heart health, potassium is another nutrient found in strawberries.
- Other Nutrients: In smaller quantities, strawberries also provide copper, iron, magnesium, phosphorus, and vitamins B6, E, and K.

| Nutrient | Strawberry (Raw) | Orange (Raw) | Apple (Raw) | Banana (Raw) |
|---|---|---|---|---|
| Calories | 32 kcal | 47 kcal | 52 kcal | 89 kcal |
| Vitamin C | 58.8 mg | 53.2 mg | 4.6 mg | 8.7 mg |

The Power of Phytochemicals and Antioxidants
Beyond basic vitamins and minerals, strawberries are loaded with powerful antioxidant plant compounds known as phytochemicals. These include flavonoids and phenolic acids, which give strawberries their deep red color and provide significant health benefits.
- Anthocyanins: The red color of strawberries is primarily due to pelargonidin, the most abundant anthocyanin. Anthocyanin content increases as the fruit ripens, and these compounds are linked to numerous health benefits, particularly heart health.
- Ellagic Acid and Ellagitannins: These polyphenols are abundant in strawberries and have been extensively studied for their potential benefits. They are converted into ellagic acid in the gut and are associated with a reduced risk of certain cancers and other diseases.
- Procyanidins: Found in the flesh and seeds, these antioxidants also contribute to the health-promoting properties of strawberries.
Conclusion: A Nutritious Addition to Any Diet
Strawberries are an exceptionally nutritious and low-calorie food, offering a potent dose of vitamins, minerals, and antioxidants in every serving. Their high vitamin C and fiber content, coupled with beneficial phytochemicals like anthocyanins and ellagic acid, make them a great choice for supporting heart health, managing blood sugar, and providing immune support. Whether enjoyed fresh, frozen in a smoothie, or added to a salad, incorporating strawberries into a regular diet is a simple and delicious way to boost your nutritional intake. For those seeking to maximize the health benefits of berries, regular consumption is recommended.
