# Build Nutrition Labels

Every packaged food product needs a nutrition label, and every recipe blog benefits from one. But creating accurate nutrition labels requires looking up every ingredient, adjusting for quantities, accounting for cooking losses, and formatting the result according to regulatory standards. It is one of the most tedious parts of food product development.

The search_foods and get_nutrition skills provide the raw data needed to build nutrition labels from scratch. Look up each ingredient in a recipe, get the per-serving nutritional breakdown, aggregate the totals, and you have the foundation for a standard nutrition facts panel. This works for food manufacturers developing new products, recipe bloggers adding nutrition info to their posts, meal prep services labeling their offerings, and restaurants adding calorie counts to menus.

While the final label still needs formatting and regulatory compliance review, having accurate nutritional data for every ingredient is the hardest and most time-consuming part. This tool handles that lookup and calculation in seconds.
