About these numbers
Strawberries are among the most nutrient-dense fruits per calorie. 100g contains 89mg of vitamin C (99% of daily target — more than oranges per gram), substantial folate, manganese, and potassium. Calorie density at 32 kcal per 100g is the lowest among popular fruits, meaning generous portions fit any calorie budget.
The polyphenol content (anthocyanins, ellagic acid, quercetin) has accumulated meaningful cardiovascular evidence. The 2013 Cassidy et al. analysis of the Nurses' Health Study (n=93,600) found 3+ servings/week of strawberries and blueberries was associated with 32% lower myocardial infarction risk in women under 50. The mechanism is improved endothelial function and reduced inflammation.

Frequently asked questions
- How many calories are in strawberries?
- 1 cup of strawberries (~152g) contains only 49 kcal — one of the lowest-calorie fruit servings available. Per 100g: 32 kcal. A single medium strawberry (~12g) is just 4 kcal; a large one (~18g) is 6 kcal. For volumetric eating, strawberries are nearly a free food.
- Are strawberries good for weight loss?
- Excellent. Calorie density of 32 kcal/100g is the lowest among popular fruits, allowing large satisfying portions in any calorie budget. High water content (~91%) and meaningful fiber (3g per cup) provide strong satiety per calorie. The 2016 Gibson et al. study showed berries reduced post-meal glucose response and increased satiety when added to mixed meals. For cut-phase snacking, strawberries are a top choice.
- Are strawberries diabetes-friendly?
- Yes, very much so. Glycemic index ~40 (low), and the glycemic load per cup is only 4–5 (low) due to small carb content per serving. The 3g of fiber further slows glucose absorption. For T2D, prediabetes, and CGM-tracking adults, strawberries produce minimal glucose response — eat freely within calorie targets. The polyphenol content may have additional metabolic benefits beyond the immediate glucose impact.
- How much vitamin C is in strawberries?
- A lot — 89mg per 100g, which is more than oranges per gram (~70mg). A single cup of strawberries provides 135mg of vitamin C, well exceeding the 75–90mg daily target. The 2020 Carr & Maggini review noted vitamin C contributes to immune function, collagen synthesis, and antioxidant defense. For practical eating, 1 cup of strawberries (or any berry mix) provides a full day's vitamin C plus substantial polyphenol benefit at trivial calorie cost.
