Nutrition API for Nutrition Apps

Nutrition apps need data they can stand behind. Recipe API gives every recipe 32 tracked nutrients per serving, grouped ingredients with linked IDs traceable to USDA FoodData Central, plus dietary flags and allergen warnings. Filter by dietary needs and nutrient ranges, then expose ingredient-level breakdowns your users can trust.
