Medjool date versus raw banana: calories, macros and portion trade-offs

What exactly is being compared?

For the numbers in this guide, Medjool date means “Dates, medjool” (USDA FoodData Central 168191). It contains 277 kcal per 100 g edible portion. This record is Medjool dates. Other varieties and date-filled products can have different weights and ingredients. Keeping that definition attached to the number prevents a plain ingredient from being mistaken for a prepared meal.

The second food is “Bananas, raw,” rather than an unspecified raw banana 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 “Bananas, raw” (FDC 173944), which contains 89 kcal per 100 g. At equal 30 g weights, the Medjool date reference supplies 83.1 kcal and raw banana supplies 26.7 kcal: a difference of 56.4 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 188 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 1.8 g protein, 75 g total carbohydrate, 0.1 g fat and 6.7 g fiber. For the illustrated 30 g portion, those amounts become 0.5 g protein, 22.5 g carbohydrate, 0 g fat and 2 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 banana, the same 100 g record reports 1.1 g protein, 22.8 g carbohydrate, 0.3 g fat, 2.6 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 30 g portion provides approximately 83.1 kcal: 30 × 277 ÷ 100. A smaller 15 g portion gives 41.5 kcal, while 45 g gives 124.7 kcal. These are calculated amounts of the named food, not claims about the weight of a standard piece, cup or restaurant serving.

The named reference is Medjool date with the pit excluded. Other varieties can have different sizes, and a fruit count alone does not guarantee the same edible weight.

Compare complete dishes, not isolated ingredients

Remove pits before weighing dates for a snack or recipe. For a blended date paste, include the original date quantity and any other ingredients, then divide the batch by the amount served.

Stuffed dates with nut butter or chocolate are mixed snacks. The date still contributes its own energy, and the filling needs an additional entry rather than being ignored because the fruit is most visible.

For an explicit ingredient example, 30 g of the named Medjool date plus 5 g olive oil gives approximately 127.3 kcal. The Medjool date contributes 83.1 kcal and the oil contributes 44.2 kcal. This is an illustrative two-ingredient calculation, not a tested recipe or a claim that Medjool date is always served with oil.

A practical side-by-side review

Write down the edible grams of Medjool date in one version and of raw banana 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 Medjool date 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.
