Banana calories per cup: 146–225 across all 2 named USDA examples

Across all 2 named USDA examples, a cup contains 146–225 calories. Their listed weights span 140–150 g, so each calorie value is calculated from that example's own gram weight and published calories per 100 g.

Compare all 2 food records, nutrition tables and USDA sources

The 2 exact records in this guide report 122–225 calories in the records' own listed source servings and 97–161 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.

Match my meal

Start with the description closest to what you ate

For Banana, begin by separating “Banana, baked” from “Banana, raw.” Choosing a card filters this source set; it does not infer the portion or fill in ingredients the chosen description does not name.

What this page compares

Named source records, not one universal meal

This guide keeps 2 named USDA records in view: 2 direct matches. All sit within “Bananas.” The exact descriptions remain the unit of comparison; the familiar heading is only the doorway into the evidence.

Why these records appear together: The deterministic grouping rule “normalized first description segment” placed these 2 records together under the exact grouping key “banana.” That rule determines membership before any nutrition result is read.

For Banana, this page can compare 2 named records from FDC 2709225 through FDC 2709224. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief

The three facts to carry into the table

Carry the denominator, exact identity, and strongest observed contrast into every number below.

Portion

126–140 g before composition

The largest source amount is 1.1× the smallest. Read per-serving calorie differences with that mass gap in view.

Composition

64 kcal separates the fixed-weight endpoints

The lower endpoint is “raw”; the higher is “baked.” This isolates density, not ingredient causation.

Discriminator

0.1 g fiber gap per 100 g

Of protein, fiber, and sodium, the strongest normalized contrast is between “raw” (1.7 g) and “baked” (1.8 g).

Observed source examples

Both records, with their own serving weights intact

The cards are ordered by calories in each record's listed serving. Serving weights differ, so use per-100-gram values to compare composition. These selected records do not define a calorie range for every banana.

Important: “Lower” begins with Banana, raw; “higher” ends with Banana, baked, using each record’s own source amount. Those labels order this selected set only—they are not endpoints for every banana meal.

Full comparison

Compare every selected FNDDS record

For Banana, serving columns preserve each record’s own listed amount, while calories per 100 g hold weight constant. A dash means the cited record does not supply that field; it does not mean the nutrient is absent.

On smaller screens, focus the table and scroll horizontally to read every column.

Portion analysis

Serving total and calorie density answer different questions

The listed source amounts run from 126 to 140 grams—a 14-gram gap before composition enters the comparison. Their own source servings run from 122 calories for “raw” to 225 for “baked.” At a fixed 100 grams, “raw” is 97 calories and “baked” is 161—a fixed-weight separation of 64 calories. For Banana, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.

The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.

Preparation analysis

The long description carries the evidence

The published descriptions distinguish forms such as “baked” and “raw”. Across the source formulations, the shared backbone includes bananas, ripe and slightly ripe, raw; differentiating rows include bananas, overripe, raw, butter, stick, unsalted, and sugars, brown. On this Banana page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.

Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.

What changes the comparison

Four drivers worth checking before choosing a record

The family label “Banana” cannot resolve the differences between Banana, baked and Banana, raw. The four checks below identify the record wording, source weight, and formulation evidence that can.

  1. 01

    Source weight before serving calories

    The source amounts span 126–140 grams. Compare per 100 grams before reading a serving-calorie gap as a composition gap.

  2. 02

    The words that split the family

    Representative record-level distinctions include “baked” and “raw”. Those phrases are evidence for choosing a record, not decorative subtitle text.

  3. 03

    Formulation evidence, with limits

    Shared source rows include bananas, ripe and slightly ripe, raw; rows that vary across the set include bananas, overripe, raw, butter, stick, unsalted, and sugars, brown. Presence is inspectable evidence, not proof of nutrient causation.

  4. 04

    The unresolved plate

    Even “Banana, baked” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Banana unknowns for correction instead of converting them into false precision.

Record matching

Match identity first; scale quantity second

Read the source name as a sequence of decisions. First confirm that banana is the right meal family. Then resolve the phrases that actually separate this set—“baked” and “raw”—before comparing gram weight. If a package, menu, or known recipe provides a closer first-party description, prefer it and keep this USDA record as a transparent fallback.

A practical matching checklist

  1. Read the complete Banana source description, including preparation and additions.
  2. Compare the listed source weight with the amount actually eaten.
  3. Prefer a current package or restaurant source when a specific branded item is known.
  4. Record toppings, sauces, cooking fat, sides, and substitutions that the selected description does not name.

Decision support from the exact records on this page

Turn source data into a better next decision

These conclusions and reading paths are computed from 2 exact records behind Banana source-record guide. Links are chosen by record identity, controlled contrast, formulation input, nutrient spread, or serving context—not by loose keyword similarity.

Equal-weight result

Banana, baked is higher in sodium per 100 g

Banana, baked reports 3 mg versus 0 mg for Banana, raw: a 3 mg difference when both are normalized to 100 g.

Inspect the underlying evidence

Check the weight before comparing serving totals

Source amounts span 126–140 g

Banana, raw uses USDA source amount (126 g), while Banana, baked uses USDA source amount (140 g). Use per 100 g for equal-weight composition; use the serving column only when those named source amounts answer your question.

Choose the record before reading the number

Banana, baked and Banana, raw are not interchangeable

The page keeps both records at the same 100 g denominator and makes Preparation wording (baked, roasted, or broiled versus raw) the explicit record-description contrast. It does not show that the wording difference caused a nutrient difference. Pick the description that matches the food in front of you rather than averaging away the distinction.
