About

Food Nutrient Analyzer estimates macro and micronutrients from ingredient lists using USDA FoodData Central and ingredient-level parsing and weight estimation logic.

Ingredients are parsed, matched to USDA foods, assigned a weight from explicit measures, USDA portions, or fallback defaults, and then aggregated into meal-level nutrition totals.

The tool is designed to be transparent about ingredient parsing, matched foods, and weight sources so users can better understand how estimates are generated.

Some ingredients may require estimated weights when exact amounts are not provided. These estimates are intended for general informational use and may not reflect exact real-world values.
