Egg, white only, raw calories: 17 per 1 egg white (33 g)
This exact USDA record reports 17 calories for 1 egg white (33 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 17 calories for 1 egg white at 33 grams. On a fixed-weight basis, the same record contains 52 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 3.5 g protein, 0 g fiber, and 55 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is eggs, grade a, large, egg white, 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 egg white at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 17–127 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2707168: “Egg, white only, raw.” 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 2707168, each row multiplies the published per-100-gram values by its stated weight. “75% of the reference weight” through “1 cup” 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 | 24.8 g | 13 kcal | 2.6 g | 0 g | 41 mg |
| 1 egg whiteUSDA-listed household measure | 33 g | 17 kcal | 3.5 g | 0 g | 55 mg |
| 1 cupUSDA-listed household measure | 245 g | 127 kcal | 26.2 g | 0 g | 407 mg |
02 · Fixed-weight context
Where 100 grams sits inside Eggs and omelets
The comparison set contains 116 exact records in the Eggs and omelets USDA category. Here, “lower quarter” describes FDC 2707168’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 2707168’s 33 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
Sodium55 mg
≈ 2% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Egg, white only, raw,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707170 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 egg white to 1 cup
USDA assigns those measures 33 g and 245 g. At this record’s fixed composition, scaled energy moves from 17 kcal to 127 kcal.
- 02
Record choice: compare with FDC 2707170
At an equal 100 g, this record has 115 mg less sodium than “Egg, white, cooked, no added fat.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Eggs, Grade A, Large, egg white
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 “white only; raw” fits. Inspect FDC 2707170 when “white; cooked; no added fat” is the more literal description of the food and preparation.

Inside the source record
Source formulation behind this USDA record
USDA links FDC 2707168 to one source input totaling 100 g in its standardized formulation. Publishing that exact provenance makes “Egg, white only, raw” inspectable beside similarly named records.
How to read this
A single-source formulation
Eggs, Grade A, Large, egg white 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.

Exact-record context
What makes this USDA record distinct?
For FDC 2707168, the close-record rule searches the USDA “Eggs and omelets” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Plain-English read
At the fixed 100-gram basis, this record lists 115 mg less sodium than “Egg, white, cooked, no added fat.”
Only the comparison record lists Salt, table. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
1 of the six displayed differences clears 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.
Shared listed inputs: Eggs, Grade A, Large, egg white.
Listed only in the comparison: Salt, table.
Portion evidence
The listed portion sets differ
This record’s reference amount is 33 g; a familiar listed measure is 1 egg white (33 g).
The comparison record’s reference amount is 33 g; a familiar listed measure is 1 egg white (33 g).
Use the 100-gram row to compare FDC 2707168 with FDC 2707170 at equal mass; use their 33 g and 33 g source amounts only for portion matching.
Evidence boundary: FDC 2707168 versus FDC 2707170 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 portion size, recipe or brand, cooking fat, toppings and add-ins.
For “Egg, white only, raw,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
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
cooking fat
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 04
toppings and add-ins
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2707168 comes from FoodData Central Survey Foods (FNDDS). Its 52 kcal per 100 g becomes 17 kcal at 33 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 egg white 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: 2707168
FNDDS food code: 31108010
The scaling for FDC 2707168 can be exact while the match to “Egg, white only, raw” is wrong. That is why this profile keeps its 33 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
