32 kcal per 100g at 91% Water — A Full Cup of Whole Strawberries (144g, 46 kcal) Logs Fewer Calories Than a Single Medium Banana

Raw strawberry has 32 kcal per 100g — placing it among the lowest-calorie fresh fruits, below apple (52 kcal), orange (47 kcal), blackberry (43 kcal), and banana (89 kcal). Only watermelon (30 kcal), lemon (29 kcal), and star fruit (31 kcal) are lower. The 91% water content means strawberry delivers substantial volume relative to its caloric contribution [1].

One cup of whole strawberries (144g) provides 46 kcal — less than half the calories in a single medium banana (105 kcal) and lower than a medium apple (95 kcal). A cup of sliced strawberries (166g) has 53 kcal; a cup of halves (152g) has 49 kcal. A single medium strawberry (12g) has just 4 kcal, making portion-level tracking straightforward.

For food journaling, strawberry's calorie count is consistent across common varieties (Chandler, Camarosa, Albion) — the range is 30–34 kcal per 100g, so using 32 kcal as a default produces minimal logging error regardless of variety.

1.84mg Vitamin C per Calorie — Strawberry Outranks Orange (1.13), Kiwi (1.52), and Pineapple (0.96) in Ascorbic Acid Efficiency per Unit Energy

Strawberry delivers 58.8mg vitamin C per 100g — 65% of the Daily Value — at only 32 kcal. This yields a vitamin C efficiency ratio of 1.84mg per calorie, exceeding orange (53.2mg at 47 kcal = 1.13 mg/kcal), green kiwi (92.7mg at 61 kcal = 1.52 mg/kcal), and pineapple (47.8mg at 50 kcal = 0.96 mg/kcal). Among common fruits, only guava (228mg at 68 kcal = 3.35 mg/kcal) delivers more vitamin C per calorie [1][2].

One cup of whole strawberries (144g) provides 84.7mg vitamin C — 94% of the daily value — in just 46 kcal. This makes strawberry one of the most calorie-efficient ways to reach the daily vitamin C target. Eight medium strawberries (96g) already provide 56.4mg (63% DV).

For nutrition journaling, if tracking vitamin C intake matters, strawberry's per-calorie efficiency means that even modest portions contribute meaningfully. A 50g serving (roughly 4 medium berries, 16 kcal) provides 29.4mg vitamin C — about one-third of the daily value.

4.9g Sugar per 100g in a Near-Equal Glucose (2.0g) and Fructose (2.4g) Split — Half the Sugar of Apple, One-Third of Grapes

Strawberry has 4.89g total sugars per 100g — one of the lowest sugar contents among fresh fruits. This is roughly half of apple (10.4g), about half of orange (9.4g), and one-third of grapes (15.5g). The sugar profile breaks down as 2.44g fructose (50%), 1.99g glucose (41%), and 0.47g sucrose (9%) — an unusually balanced glucose-to-fructose ratio compared to apple's heavily fructose-dominant profile (57% fructose) [1][3].

One cup of whole strawberries (144g) has 7.0g total sugar — equivalent to about 1.8 teaspoons of table sugar in caloric terms. For comparison, a medium apple has 18.9g, a medium banana has 14.4g, and a cup of grapes has 23.4g sugar. Strawberry delivers noticeable sweetness with substantially lower sugar per volume.

For food journaling, strawberry is one of the easiest fruits to track for those monitoring sugar intake. The low 4.9g per 100g value, combined with the high water content, means even generous portions contribute modest sugar totals.

Freezing Preserves 70% of the Vitamin C (58.8 → 41.2mg) but Adding Sugar Triples the Calories (32 → 96 kcal) — What Changes Between Fresh and Frozen Variants

Frozen unsweetened strawberries retain 41.2mg vitamin C per 100g — 70% of the fresh value (58.8mg). Fiber holds steady at 2.1g (versus 2.0g fresh), and calories increase slightly to 35 kcal (from 32 kcal) due to minor water loss during the freezing process. Potassium drops modestly from 153mg to 148mg. Iron, interestingly, appears higher in frozen (0.75mg vs 0.41mg), likely due to concentration effects during processing [1][4].

Frozen sweetened sliced strawberries tell a different story: the added sugar pushes calories to 96 kcal per 100g — exactly 3x the fresh value. Sugars jump from 4.9g to 24.0g, and total carbohydrates rise from 7.7g to 25.9g. Vitamin C remains roughly stable at 41.4mg because the fruit's ascorbic acid is diluted by the sugar mass but not destroyed by it.

For food journaling, the frozen unsweetened variant is nutritionally close to fresh and is a practical substitute for smoothies and off-season use. The frozen sweetened variant, however, requires careful portion tracking — a single cup (255g) delivers 245 kcal and 61g sugar, comparable to a soft drink in sugar content.

10–60mg Anthocyanins per 100g Fresh Weight, Dominated by Pelargonidin 3-Glucoside — The Red Pigment That Standard Nutrition Panels Never Display

Strawberry's red color comes from anthocyanins — water-soluble pigments that range from 9.8 to 60.3mg per 100g fresh weight depending on variety, ripeness, and growing conditions. The dominant anthocyanin is pelargonidin 3-glucoside, accounting for approximately 70–90% of total anthocyanin content. Pelargonidin 3-rutinoside and pelargonidin 3-glucoside-succinate are present in smaller amounts [2][5].

Total polyphenol content in fresh strawberries ranges from 149 to 517mg GAE per 100g (gallic acid equivalents), placing strawberry among the most polyphenol-rich common fruits. Ellagic acid, quercetin, and kaempferol glycosides contribute alongside the anthocyanins. These compounds are not captured in standard USDA nutrient panels [2].

For food journaling, standard calorie trackers will not show anthocyanin or polyphenol values. If tracking phytonutrient diversity matters, note that deeper-red, fully ripe strawberries generally contain higher anthocyanin concentrations than pale or under-ripe berries. Freezing preserves most anthocyanin content, while cooking (jam-making) reduces it significantly.

Practical Tips for Strawberry

  • 1

    One cup of whole strawberries (144g) = 46 kcal and 84.7mg vitamin C (94% DV). For calorie-efficient vitamin C tracking, strawberry provides nearly 2mg of vitamin C per calorie — better than orange, kiwi, or pineapple.

  • 2

    Strawberry has only 4.9g sugar per 100g — among the lowest of any fresh fruit. A full cup has just 7g sugar. Compare that to a cup of grapes (23.4g) or a medium banana (14.4g). This makes strawberry particularly easy to fit within sugar-aware food logs.

  • 3

    Frozen unsweetened strawberries are nutritionally close to fresh (35 vs 32 kcal, 41.2 vs 58.8mg vitamin C). For smoothies or off-season use, frozen unsweetened is a practical substitute. Avoid frozen sweetened (96 kcal, 24g sugar per 100g) unless you account for the tripled calorie density.

  • 4

    A single medium strawberry (12g) has only 4 kcal. This makes strawberries easy to track by count: 8 medium berries ≈ 96g ≈ 31 kcal. For rough logging, 10 berries ≈ 120g ≈ 38 kcal.

  • 5

    Strawberry's deep red color correlates with anthocyanin content (10–60mg/100g), but this does not appear on standard nutrition labels. Fully ripe, darker berries contain more anthocyanins than pale ones. Freezing preserves most of this content; jam-making reduces it.

Frequently Asked Questions — Strawberry

How many calories are in a cup of strawberries?
One cup of whole strawberries (144g) has about 46 calories. A cup of halves (152g) has 49 calories, and a cup of sliced strawberries (166g) has 53 calories. Per 100g, raw strawberries have 32 calories — among the lowest of any fresh fruit.
Are frozen strawberries as nutritious as fresh?
Frozen unsweetened strawberries retain about 70% of the vitamin C found in fresh (41.2mg vs 58.8mg per 100g), while fiber (2.1g vs 2.0g) and most minerals remain comparable. The calorie difference is small: 35 vs 32 kcal per 100g. However, frozen sweetened strawberries have 96 kcal and 24g sugar per 100g — triple the calories of fresh — due to added sugar.
How much sugar is in strawberries?
Raw strawberries have 4.89g sugar per 100g — about half the sugar in an apple (10.4g) and one-third of grapes (15.5g). One cup of whole strawberries (144g) has approximately 7.0g total sugar. The sugar splits nearly evenly between fructose (2.4g) and glucose (2.0g), with minimal sucrose (0.5g).
Do strawberries have more vitamin C than oranges?
Per 100g, strawberries have more vitamin C than oranges: 58.8mg vs 53.2mg. Per calorie, the difference is even greater — strawberry delivers 1.84mg vitamin C per calorie compared to orange's 1.13mg. One cup of strawberries (144g) provides 84.7mg vitamin C (94% DV), while a medium orange (131g) provides 69.7mg (77% DV).
How many strawberries can I eat in 100 calories?
At 32 kcal per 100g, you can eat about 312g of strawberries for 100 calories — that's roughly 26 medium strawberries or just over 2 cups of whole berries. This makes strawberry one of the most volume-efficient fruits for calorie-conscious logging.
