The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 55 calories for USDA reference amount at 63 grams. On a fixed-weight basis, the same record contains 87 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 1 g protein, 1.9 g fiber, and 104 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is lotus root, cooked, boiled, drained, without salt, representing 96.8% 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 9–109 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 2709936: “Lotus root, cooked.” 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 2709936, each row multiplies the published per-100-gram values by its stated weight. “1 slice” through “1 cup” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 sliceUSDA-listed household measure | 10 g | 9 kcal | 0.2 g | 0.3 g | 17 mg |
| USDA reference amountExact record reference weight | 63 g | 55 kcal | 1 g | 1.9 g | 104 mg |
| 1 cupUSDA-listed household measure | 125 g | 109 kcal | 1.9 g | 3.8 g | 206 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, “upper quarter” describes FDC 2709936’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 2709936’s 63 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Vitamin C; 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
Vitamin C17 mg
≈ 19% DV. This does not cross the FDA’s 20% ‘high’ guide.
Dietary fiber1.9 g
≈ 7% DV. This does not cross the FDA’s 20% ‘high’ guide.
Tradeoff-side signals
Sodium104 mg
≈ 5% DV. This does not cross the FDA’s 20% ‘high’ guide.

04 · Highest-impact checks
The three levers most worth resolving first
For “Lotus root, cooked,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2709875 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 slice to 1 cup
USDA assigns those measures 10 g and 125 g. At this record’s fixed composition, scaled energy moves from 9 kcal to 109 kcal.
- 02
Record choice: compare with FDC 2709875
At an equal 100 g, this record has 5.9 g more carbohydrate than “Beets, fresh, cooked, fat added.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Lotus root, cooked, boiled, drained, without salt
The source formulation has 3 input rows; Lotus root, cooked, boiled, drained, without salt supplies 96.8% 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 “cooked” fits. Inspect FDC 2709875 when “fresh; cooked; fat added” is the more literal description of the food and preparation.

Exact-record context
What makes this USDA record distinct?
For FDC 2709936, 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
At the fixed 100-gram basis, this record lists 20 more calories and 5.9 g more carbohydrate than “Beets, fresh, cooked, fat added.”
Only this record lists Lotus root, cooked, boiled, drained, without salt. Only the comparison record lists Beets, raw. Those formulation rows identify different source records; they do not prove which input caused a nutrient difference.
2 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.
Shared listed inputs: Oil or table fat, NFS; Salt, table.
Listed only in this record: Lotus root, cooked, boiled, drained, without salt.
Listed only in the comparison: Beets, raw.
Portion evidence
The listed portion sets differ
This record’s reference amount is 63 g; a familiar listed measure is 1 cup (125 g).
The comparison record’s reference amount is 88 g; a familiar listed measure is 1 cup (175 g).
Use the 100-gram row to compare FDC 2709936 with FDC 2709875 at equal mass; use their 63 g and 88 g source amounts only for portion matching.
Evidence boundary: FDC 2709936 versus FDC 2709875 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 “Lotus root, cooked,” 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 2709936 comes from FoodData Central Survey Foods (FNDDS). Its 87 kcal per 100 g becomes 55 kcal at 63 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: 2709936
FNDDS food code: 75218501
The scaling for FDC 2709936 can be exact while the match to “Lotus root, cooked” is wrong. That is why this profile keeps its 63 g weight, 3-row source formulation, and selection uncertainty beside the arithmetic.
