Cereal or granola bar (Kellogg's Special K bar) calories: 94 per 1 bar (23 g)
This exact USDA record reports 94 calories for 1 bar (23 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 94 calories for 1 bar at 23 grams. On a fixed-weight basis, the same record contains 409 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 2.1 g protein, 0.4 g fiber, and 98 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is rice and wheat cereal bar, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 bar at the identical weight. We use the familiar household label here without changing the source calculation.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2708087: “Cereal or granola bar (Kellogg's Special K bar).” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2708087, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “125% of the reference weight” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 75% of the reference weightArithmetic scenario from the reference weight | 17.3 g | 71 kcal | 1.6 g | 0.3 g | 74 mg |
| 1 barUSDA-listed household measure | 23 g | 94 kcal | 2.1 g | 0.4 g | 98 mg |
| 125% of the reference weightArithmetic scenario from the reference weight | 28.8 g | 118 kcal | 2.6 g | 0.5 g | 123 mg |
02 · Fixed-weight context

The comparison set contains 28 exact records in the Cereal bars USDA category. Here, “middle half” describes FDC 2708087’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708087’s 23 g reference weight, none of the compatible strength-side nutrients evaluated here reaches 5% Daily Value; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.
Strength-side signals
No compatible strength-side nutrient evaluated here reaches 5% DV at this reference weight, so this page does not manufacture a “strength” from a negligible percentage.
Tradeoff-side signals
Sodium98 mg
≈ 4% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Cereal or granola bar (Kellogg's Special K bar),” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708083 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 23 g
A 25% weight move in either direction spans 17.3–28.8 g. When composition is held constant, those endpoints calculate to 71 kcal and 118 kcal.
- 02
Record choice: compare with FDC 2708083
At an equal 100 g, this record has 4.9 g more protein than “Cereal or granola bar (Kellogg's Nutri-Grain Cereal Bar).” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Rice and Wheat cereal bar
USDA derives this record from one listed source-input row at 100 g. Real preparations can still differ in water, cooking state, brand, and served weight.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when the exact wording “Cereal or granola bar (Kellogg's Special K bar)” fits. Inspect FDC 2708083 when the exact wording “Cereal or granola bar (Kellogg's Nutri-Grain Cereal Bar)” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2708087 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Cereal or granola bar (Kellogg's Special K bar)” inspectable beside similarly named records.
How to read this
A single-source formulation
Rice and Wheat cereal bar is the only listed source input for this record. That does not mean every real-world version is identical; brands, preparation, water content, and portion weight can still differ.

Plain-English read
At the fixed 100-gram basis, this record lists 44 more calories, 4.9 g more protein, and 1.2 g less dietary fiber than “Cereal or granola bar (Kellogg's Nutri-Grain Cereal Bar).”
Only this record lists Rice and Wheat cereal bar. Only the comparison record lists Snacks, KELLOGG, KELLOGG'S, NUTRI-GRAIN Cereal Bars, fruit. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
4 of the six displayed differences clear the documented materiality screen. It is a reading aid, not a health rating.
Formulation evidence
The listed formulations differ
The formulation rows differ, but the source data do not isolate which component caused any nutrient difference. Input weights describe the standardized formulation—not final plated proportions.
Listed only in this record: Rice and Wheat cereal bar.
Listed only in the comparison: Snacks, KELLOGG, KELLOGG'S, NUTRI-GRAIN Cereal Bars, fruit.
Portion evidence
The listed portion sets differ
This record’s reference amount is 23 g; a familiar listed measure is 1 bar (23 g).
The comparison record’s reference amount is 37 g; a familiar listed measure is 1 Nutri-Grain Bar (37 g).
Use the 100-gram row to compare FDC 2708087 with FDC 2708083 at equal mass; use their 23 g and 37 g source amounts only for portion matching.
Evidence boundary: FDC 2708087 versus FDC 2708083 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with piece or portion size, recipe or brand, fillings or frosting, added fats and sugars.
For “Cereal or granola bar (Kellogg's Special K bar),” resolve piece or portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
piece or portion size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
fillings or frosting
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
- 04
added fats and sugars
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708087 comes from FoodData Central Survey Foods (FNDDS). Its 409 kcal per 100 g becomes 94 kcal at 23 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 bar has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2708087
FNDDS food code: 53710700
The scaling for FDC 2708087 can be exact while the match to “Cereal or granola bar (Kellogg's Special K bar)” is wrong. That is why this profile keeps its 23 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
