Add up the total calories and macros for a complete meal by looking up each ingredient individually.

Calorie counting for home-cooked meals is tedious. Every ingredient needs to be weighed, looked up, and calculated individually, then totaled for the whole dish. A simple stir-fry might have ten ingredients, each contributing different amounts of calories, protein, fat, and carbs. Most people either skip the calculation entirely or estimate badly.

With the search_foods and get_nutrition skills, you can look up every ingredient in a meal and calculate the total nutritional content. List your ingredients and quantities, get the per-ingredient breakdown, and add them up for an accurate total. This turns what used to be a 20-minute spreadsheet exercise into a quick conversation.

This is essential for anyone tracking calories -- dieters, athletes, people with diabetes managing carb intake, or anyone following a structured nutrition plan. It is also valuable for food bloggers who want to include accurate nutrition labels with their recipes and meal prep services that need to label their products correctly.
