Strawberry versus raw blueberry: calories, macros and portion trade-offs

What exactly is being compared?

For the numbers in this guide, strawberry means “Strawberries, raw” (USDA FoodData Central 167762). It contains 32 kcal per 100 g edible portion. The record is raw strawberry without added sweetener. Jam, syrup and sweetened frozen fruit should use different entries. Keeping that definition attached to the number prevents a plain ingredient from being mistaken for a prepared meal.

The second food is “Blueberries, raw,” rather than an unspecified raw blueberry dish. Preparation is part of the comparison: a raw ingredient, cooked grain, spread or complete meal is not automatically interchangeable with another food just because both appear in a calorie search.

Calories on an equal-weight basis

The comparison food is “Blueberries, raw” (FDC 171711), which contains 57 kcal per 100 g. At equal 150 g weights, the strawberry reference supplies 48 kcal and raw blueberry supplies 85.5 kcal: a difference of 37.5 kcal. That is a calculation for these records, not a universal ranking of foods or an instruction to exchange equal portions.

The gap per 100 g is 25 kcal. Doubling both weighed amounts doubles that calculated gap; halving both halves it. This explains the table without claiming that either food has a fixed portion or that a lower-energy choice provides an identical eating experience.

Protein, carbohydrate, fat and fiber

The same 100 g reference provides 0.7 g protein, 7.7 g total carbohydrate, 0.3 g fat and 2 g fiber. For the illustrated 150 g portion, those amounts become 1 g protein, 11.5 g carbohydrate, 0.5 g fat and 3 g fiber. Calories and individual nutrients describe different parts of the food, so keep all of them on the same portion basis when reading the table.

For raw blueberry, the same 100 g record reports 0.7 g protein, 14.5 g carbohydrate, 0.3 g fat, 2.4 g fiber. Read those values as a profile rather than a single score. The combination you want depends on the rest of the meal and any personal nutrition requirements.

Why the realistic portion matters

A weighed 150 g portion provides approximately 48 kcal: 150 × 32 ÷ 100. A smaller 75 g portion gives 24 kcal, while 225 g gives 72 kcal. These are calculated amounts of the named food, not claims about the weight of a standard piece, cup or restaurant serving.

The raw strawberry entry excludes leaves and added sweetener. Removing tops before weighing makes a bowl of large berries and a bowl of small berries comparable on an edible-weight basis.

Compare complete dishes, not isolated ingredients

Sliced berries spread across yogurt can appear more plentiful than whole berries in a bowl. The slicing changes presentation, while the measured edible amount remains the same.

Jam, syrup-packed strawberries and strawberries under whipped cream describe different preparations. Fruit is one ingredient in those foods; a plain raw berry value cannot describe the dessert around it.

For an explicit ingredient example, 150 g of the named strawberry plus 5 g olive oil gives approximately 92.2 kcal. The strawberry contributes 48 kcal and the oil contributes 44.2 kcal. This is an illustrative two-ingredient calculation, not a tested recipe or a claim that strawberry is always served with oil.

A practical side-by-side review

Write down the edible grams of strawberry in one version and of raw blueberry in the alternative. Include any accompanying foods that change between versions. A swap that uses different amounts of bread, dressing or topping will not have the same calorie difference as the equal-weight food comparison. Keeping the ingredients visible explains the result.

In BiteCal, start with a photo of the strawberry portion and the rest of the meal. Review the proposed food name, preparation, amount and visible additions before saving the calorie and macro estimate. If you already know the gram weight, use it as a check rather than accepting a visually plausible portion. A photo cannot establish a hidden oil quantity or replace the identity of a packaged product.

The nutrient figures come from USDA SR Legacy, final release April 2018. They provide a reproducible reference for the named food rather than a laboratory result for your own serving. Use the current package or restaurant information when it describes your exact product more closely. Rounding explains small differences between displayed portions; calculations here use the retained unrounded reference values.
