The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 176 calories for USDA reference amount at 28 grams. On a fixed-weight basis, the same record contains 628 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 4.2 g protein, 2.7 g fiber, and 0 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is nuts, hazelnuts or filberts, representing 100% of the record’s listed input weight. These are provenance for a standardized calculation, not a recipe for your plate.
The reference amount and 1 cup answer different portion questions. Their values are scaled independently from the same per-100-gram source record.
The household measures attached to this record span roughly 9–848 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 2707502: “Hazelnuts.” 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 2707502, each row multiplies the published per-100-gram values by its stated weight. “1 nut” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 nutUSDA-listed household measure | 1.5 g | 9 kcal | 0.2 g | 0.1 g | 0 mg |
| 1 packageUSDA-listed household measure | 50 g | 314 kcal | 7.5 g | 4.9 g | 0 mg |
| 1 cupUSDA-listed household measure | 135 g | 848 kcal | 20.3 g | 13.1 g | 0 mg |
02 · Fixed-weight context
Where 100 grams sits inside Nuts and seeds
The comparison set contains 68 exact records in the Nuts and seeds USDA category. Here, “upper quarter” describes FDC 2707502’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 2707502’s 28 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Magnesium; the larger tradeoff-side percentage is Saturated fat. 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
Magnesium46 mg
≈ 11% DV. This does not cross the FDA’s 20% ‘high’ guide.
Dietary fiber2.7 g
≈ 10% DV. This does not cross the FDA’s 20% ‘high’ guide.
Tradeoff-side signals
Saturated fat1.2 g
≈ 6% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Hazelnuts,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2707505 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 nut to 1 cup
USDA assigns those measures 1.5 g and 135 g. At this record’s fixed composition, scaled energy moves from 9 kcal to 848 kcal.
- 02
Record choice: compare with FDC 2707505
At an equal 100 g, this record has 6.2 g less carbohydrate than “Mixed nuts, unroasted.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Single listed source: Nuts, hazelnuts or filberts
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 “Hazelnuts” fits. Inspect FDC 2707505 when “unroasted” is the more literal description of the food and preparation.

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, preparation, added fat, sauce or seasoning.
For “Hazelnuts,” 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
preparation
Match the method named by the source—such as baked, fried, boiled, or grilled—before scaling. Preparation can change both water content and the ingredients retained in the finished food.
- 03
added 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
sauce or seasoning
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 2707502 comes from FoodData Central Survey Foods (FNDDS). Its 628 kcal per 100 g becomes 176 kcal at 28 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.” We display it as a USDA reference amount because it is a database comparison point—not a suggested portion or a claim about what most people should eat.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2707502
FNDDS food code: 42107000
The scaling for FDC 2707502 can be exact while the match to “Hazelnuts” is wrong. That is why this profile keeps its 28 g weight, 1-row source formulation, and selection uncertainty beside the arithmetic.
