What are the macros of a strawberry?

4 min read

Composed of over 91% water, strawberries are a hydrating fruit with a surprisingly lean macronutrient profile. Understanding what are the macros of a strawberry reveals why they are a smart, low-calorie choice for health-conscious diets, from weight loss to keto.

Quick Summary

Strawberries are primarily composed of carbohydrates from natural sugars and fiber, with very small amounts of protein and fat, making them a low-calorie, nutrient-dense fruit.

Key Points

  • Carbohydrate Content: A 100g serving of strawberries contains about 7.7g of total carbohydrates, predominantly from natural sugars and dietary fiber.

  • Low Net Carbs: With approximately 2g of fiber per 100g, strawberries have a low net carb count of around 5-6g, making them suitable for low-carb diets like keto when consumed in moderation.

  • Negligible Fat and Protein: Strawberries contain minimal fat (~0.3g per 100g) and are not a significant source of protein (~0.7g per 100g).

  • High in Fiber: The fiber in strawberries aids digestion and helps promote a feeling of fullness, which is beneficial for weight management.

  • Low Calorie Density: Due to their low calorie count (~32 kcal per 100g) and high water content, strawberries are an excellent food for calorie-controlled diets.

  • Low Glycemic Index: The low glycemic index of strawberries means they cause a slow and gradual rise in blood sugar, making them a safe choice for many individuals managing blood glucose levels.

The Macronutrient Breakdown of a Strawberry

For a standard 100-gram serving of raw strawberries, the macronutrient profile is predominantly carbohydrates, with minimal protein and virtually no fat. This balance, combined with their high water content, makes them a satisfyingly low-energy-density food.

Carbohydrates

Carbohydrates are the primary macronutrient in strawberries. In a 100-gram serving, you will find approximately 7.7 to 8 grams of total carbohydrates. A significant portion of these carbs comes from simple, natural sugars like glucose and fructose, which account for about 4.9 grams. The sweetness of strawberries is balanced by their fiber content, which helps manage how quickly the body absorbs these sugars. Fiber comprises around 2 grams of the total carbohydrate count in a 100g serving. The resulting net carbohydrate count, calculated by subtracting the fiber, is impressively low, at around 5-6 grams.

Protein

Strawberries are not a significant source of protein. A 100-gram serving provides less than 1 gram of protein, specifically about 0.7 grams. While every gram of protein contributes to your daily total, it is clear that strawberries are not the right food to help meet high protein goals. Pairing strawberries with a protein-rich food like Greek yogurt is a common strategy to create a more balanced snack.

Fat

One of the most notable features of a strawberry's macronutrient profile is its negligible fat content. A 100-gram serving contains only about 0.3 grams of fat, most of which is polyunsaturated fatty acids found in the tiny seeds. This makes them an ideal food for low-fat diets.

Nutritional Profile Beyond the Macros

Beyond their macros, strawberries offer a wealth of micronutrients that contribute to their health benefits. They are particularly known for their high vitamin C content, with a single cup providing more than the recommended daily amount.

Key micronutrients include:

  • Vitamin C: An antioxidant essential for immune function and skin health.
  • Manganese: An important trace element that plays a role in metabolism.
  • Folate (Vitamin B9): Critical for tissue growth and cell function, especially for pregnant women.
  • Potassium: A mineral that helps regulate blood pressure.
  • Antioxidants: Strawberries are rich in powerful antioxidant compounds like anthocyanins, which give them their red color and provide anti-inflammatory effects.

Strawberries in Different Dietary Plans

Thanks to their favorable macronutrient breakdown, strawberries are a versatile fruit that fits well into various eating plans.

Weight Loss Diets

Strawberries are an excellent component of a weight loss diet due to their low-calorie density and high fiber content. The fiber helps promote a feeling of fullness, which can reduce overall calorie intake. Their natural sweetness also helps curb cravings for more processed, sugary snacks. Swapping a high-calorie dessert for a bowl of strawberries is a simple and effective strategy for cutting calories.

Keto and Low-Carb Diets

While many fruits are off-limits on a ketogenic diet due to high sugar content, strawberries are considered a keto-friendly option when eaten in moderation. Their low net carb count allows them to be incorporated into a meal plan without risking ketosis. A standard serving (about one cup) provides around 8 grams of net carbs, but careful portion control is still necessary. This makes them a great way to add a touch of sweetness to keto-friendly meals like salads or smoothies.

Diabetes Management

Strawberries are safe for most individuals with diabetes, as they have a relatively low glycemic index of 40. This means they do not cause a significant spike in blood sugar levels. The fiber content helps to further regulate blood sugar, and some studies suggest that the fruit's compounds can improve insulin sensitivity.

Incorporating Strawberries into Your Diet

There are countless ways to enjoy the macronutrient benefits of strawberries:

  • Snack fresh: Enjoy a handful of fresh, whole strawberries on their own for a simple and satisfying snack. For added satiety, pair them with a small amount of nuts or cheese.
  • Enhance smoothies: Blend fresh or frozen strawberries into a smoothie with Greek yogurt and almond milk for a delicious, nutrient-packed drink.
  • Top salads: Add sliced strawberries to salads with greens, nuts, and a light vinaigrette for a burst of flavor and antioxidants.
  • Make yogurt parfaits: Create a layered parfait with Greek yogurt, strawberries, and a sprinkle of granola or chia seeds for a balanced meal or dessert.
  • Infuse water: Add fresh, sliced strawberries to your water bottle for a refreshing, flavorful, and low-calorie drink.

Conclusion: A Small Fruit with Big Macro Benefits

In summary, the macronutrient composition of strawberries is low in calories, dominated by carbohydrates, and contains negligible amounts of protein and fat. Their high fiber and water content make them an excellent food for managing appetite and promoting satiety, which is beneficial for weight loss. The natural sugars are balanced by fiber, giving them a low glycemic index and making them suitable for blood sugar management. Ultimately, the macros of a strawberry, combined with their abundant micronutrients and antioxidants, make them a healthy, versatile, and delicious addition to almost any balanced diet.
