Seaweed, raw calories: 4 per 10 g
This exact USDA record reports 4 calories for 10 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 4 calories for USDA reference amount at 10 grams. On a fixed-weight basis, the same record contains 41 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 0.4 g protein, 0.1 g fiber, and 38 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is seaweed, kelp, raw, representing 33.3% of the record’s listed input weight. The record contains 3 source-input rows in all. 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 4–33 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 2709805: “Seaweed, 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 2709805, 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 | 7.5 g | 3 kcal | 0.3 g | 0.1 g | 29 mg |
| USDA reference amountExact record reference weight | 10 g | 4 kcal | 0.4 g | 0.1 g | 38 mg |
| 1 cupUSDA-listed household measure | 80 g | 33 kcal | 2.8 g | 0.6 g | 307 mg |
02 · Fixed-weight context
Where 100 grams sits inside Other vegetables and combinations
The comparison set contains 122 exact records in the Other vegetables and combinations USDA category. Here, “middle half” describes FDC 2709805’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 2709805’s 10 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
Sodium38 mg
≈ 2% DV. This does not cross the FDA’s 20% ‘high’ guide.
Saturated fat0 g
≈ 0% DV. This does not cross the FDA’s 20% ‘high’ guide.
04 · Highest-impact checks
The three levers most worth resolving first
For “Seaweed, raw,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709989 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 10 g
A 25% weight move in either direction spans 7.5–12.5 g. When composition is held constant, those endpoints calculate to 3 kcal and 5 kcal.
- 02
Record choice: compare with FDC 2709989
At an equal 100 g, this record has calories than “Seaweed, cooked, no added fat.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Seaweed, kelp, raw
The source formulation has 3 input rows; Seaweed, kelp, raw supplies 33.3% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
Keep this record when “raw” fits. Inspect FDC 2709989 when “cooked; no added fat” is the more literal description of the food and preparation.

Exact-record context
What makes this USDA record distinct?
For FDC 2709805, the close-record rule searches the USDA “Other vegetables and combinations” 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
The six displayed nutrient values are close under a conservative materiality screen. Small differences remain exact source values, not evidence that one food is preferable.
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: Seaweed, kelp, raw; Seaweed, laver, raw; Seaweed, wakame, raw.
The ingredient codes overlap, while at least one listed amount, weight, sequence, or formulation detail differs.
Portion evidence
The listed portion sets differ
This record’s reference amount is 10 g; a familiar listed measure is 1 cup (80 g).
The comparison record’s reference amount is 50 g; a familiar listed measure is 1 cup (100 g).
Use the 100-gram row to compare FDC 2709805 with FDC 2709989 at equal mass; use their 10 g and 50 g source amounts only for portion matching.
Evidence boundary: FDC 2709805 versus FDC 2709989 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, raw versus cooked weight, cooking method, added fat or sauce.
For “Seaweed, 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
raw versus cooked weight
Match the food state before matching the number. Cooking, draining, or added liquid can change grams and concentration even when the food name barely changes.
- 03
cooking method
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.
- 04
added fat or sauce
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 2709805 comes from FoodData Central Survey Foods (FNDDS). Its 41 kcal per 100 g becomes 4 kcal at 10 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: 2709805
FNDDS food code: 75127500
The scaling for FDC 2709805 can be exact while the match to “Seaweed, raw” is wrong. That is why this profile keeps its 10 g weight, 3-row source formulation, and selection uncertainty beside the arithmetic.
