Recipe Nutrition Calculator

Develop a comprehensive nutrition analysis tool for home cooks and meal planners who want to understand the nutritional content of their recipes and track their dietary intake accurately. Many people struggle to estimate calories and nutrients in homemade meals, making it difficult to maintain healthy eating goals.

What You'll Build:

Your application should allow users to input recipe ingredients with quantities, automatically calculate nutritional information per serving, and provide detailed breakdowns of calories, macronutrients, vitamins, and minerals. The tool should scale recipes up or down while maintaining accurate nutritional ratios.

Key User Stories:

• As a user, I want to search for ingredients by name and get auto-suggestions from a comprehensive food database
• As a user, I want to specify quantities in various units (cups, grams, ounces) and have the system convert everything consistently
• As a user, I want to see a detailed nutrition label for my recipe including calories, protein, carbs, fat, fiber, and key vitamins
• As a user, I want to adjust serving sizes and see nutrition information update automatically for my portion
• As a user, I want to save my recipes and build a personal cookbook with nutritional data for each dish
• As a user, I want to see how my recipe fits into daily nutritional goals and dietary restrictions

Technical Implementation:

Implement robust calculation logic with comprehensive input validation and error handling. Consider data persistence for calculation history and result formatting options. Focus on user experience with clear feedback and responsive design patterns.
