Portion analysis
Serving total and calorie density answer different questions
The listed source amounts run from 225 to 315 grams—a 90-gram gap before composition enters the comparison. Their own source servings run from 290 calories for “with beans” to 539 for “beef or pork, with beans and rice.” At a fixed 100 grams, “with beans” is 129 calories and “beef or pork” is 213—a fixed-weight separation of 84 calories. For Burrito bowl, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.
The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.
Preparation analysis
The long description carries the evidence
The published descriptions distinguish forms such as “with beans”, “chicken, with beans”, “chicken, with beans and rice”, “beef or pork, with beans”, and “beef or pork, with beans and rice”. Across the source formulations, the shared backbone includes cheese and queso as ingredient and salt, table; differentiating rows include beverages, water, tap, drinking, refried beans, canned, traditional, reduced sodium, beef as ingredient in recipes, and chicken as ingredient in recipes. On this Burrito bowl page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.
Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.
