The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 242 calories for 1 cup at 200 grams. On a fixed-weight basis, the same record contains 121 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 17.1 g protein, 2 g fiber, and 726 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is restaurant, chinese, vegetable lo mein, without meat, representing 78.9% of the record’s listed input weight. The record contains 2 source-input rows in all. 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 cup 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 2708800: “Lo mein, with shrimp.” 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 2708800, 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 | 150 g | 182 kcal | 12.8 g | 1.5 g | 545 mg |
| 1 cupUSDA-listed household measure | 200 g | 242 kcal | 17.1 g | 2 g | 726 mg |
| 125% of the reference weightArithmetic scenario from the reference weight | 250 g | 303 kcal | 21.4 g | 2.5 g | 908 mg |

04 · Highest-impact checks
The three levers most worth resolving first
For “Lo mein, with shrimp,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2706827 alternative, and its source-formulation identity.
- 01
Portion sensitivity around 200 g
A 25% weight move in either direction spans 150–250 g. When composition is held constant, those endpoints calculate to 182 kcal and 303 kcal.
- 02
Record choice: compare with FDC 2706827
At an equal 100 g, this record has 11.9 g more carbohydrate than “Shrimp chow mein or chop suey, no noodles.” That is a record-level contrast; it does not identify which ingredient caused the difference.
- 03
Formulation anchor: Restaurant, Chinese, vegetable lo mein, without meat
The source formulation has 2 input rows; Restaurant, Chinese, vegetable lo mein, without meat supplies 78.9% 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 “with shrimp” fits. Inspect FDC 2706827 when “no noodles” is the more literal description of the food and preparation.

Listed only in this record: Restaurant, Chinese, vegetable lo mein, without meat.
Listed only in the comparison: Restaurant, Chinese, vegetable chow mein, without meat or noodles.
Portion evidence
The listed portion sets differ
This record’s reference amount is 200 g; a familiar listed measure is 1 cup (200 g).

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 amount served, cooked-to-dry ratio, sauce or mix-ins, added fat.
For “Lo mein, with shrimp,” resolve amount served first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
amount served
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
cooked-to-dry ratio
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
sauce or mix-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.
- 04
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.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708800 comes from FoodData Central Survey Foods (FNDDS). Its 121 kcal per 100 g becomes 242 kcal at 200 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 cup 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: 2708800
FNDDS food code: 58136130
The scaling for FDC 2708800 can be exact while the match to “Lo mein, with shrimp” is wrong. That is why this profile keeps its 200 g weight, 2-row source formulation, and selection uncertainty beside the arithmetic.
