Implement Smart Food Insights & Alternatives Feature for Enhanced Nutrition Tracking

[Copilot]

This PR implements a comprehensive Smart Food Insights & Alternatives system that transforms BiteBalance from a simple calorie tracker into an intelligent nutrition coach. The feature enhances the existing photo-based meal recognition with advanced nutritional analysis, educational content, and actionable health recommendations.

Overview

The Smart Food Insights feature analyzes nutrition data from scanned meals using Google Gemini AI and provides users with:

• Intelligent health scoring (A-D grades) based on nutritional quality
• Educational insights about meal content in a non-judgmental way
• Healthier alternatives when unhealthy aspects are detected
• Seasonal ingredient recommendations to promote local, sustainable eating
• Visual nutrition quality indicators and interactive educational tooltips

Key Features Implemented

🧠 Smart Nutrition Analysis Engine

• Health Scoring System: Assigns letter grades (A-D) and numerical scores (0-100) based on sodium, sugar, calorie, and fat content
• Intelligent Insights: Automatically identifies positive aspects (good protein, low sodium) and concerns (high sugar, excessive calories)
• Macronutrient Balance: Analyzes protein/carbs/fats ratios and provides balance recommendations

🥗 Healthier Alternatives System

• Contextual Suggestions: When high sodium, sugar, or calories are detected, provides specific alternatives
• Category-Based Recommendations: Organized suggestions for Low Sodium, Lower Sugar, Calorie Conscious, and Protein Boost
• Actionable Tips: Detailed preparation methods and expected benefits (e.g., "Reduces sodium by up to 300mg per serving")

🌱 Seasonal Recommendations

• Dynamic Seasonal Data: Comprehensive database of seasonal ingredients for all four seasons
• Environmental Awareness: Promotes locally available, in-season ingredients with environmental benefits messaging
• Seasonal Eating Tips: Season-specific advice (e.g., "Focus on detoxifying foods like leafy greens in spring")

📚 Educational Content

• "Did You Know?" Facts: Personalized educational content based on meal nutritional profile
• Interactive Tooltips: Hover information explaining the importance of each nutrient
• Non-Judgmental Approach: Encouraging, educational tone that empowers rather than shames

🎨 Enhanced UI/UX

• Visual Quality Indicators: Color-coded progress bars showing nutrient levels against recommended maximums
• Nutrition Badges: Quick health grade displays with circular progress indicators
• Expandable Sections: Accordion-style organization for detailed insights without overwhelming users
• Modal Dialogs: Clean, organized display of alternatives with expandable benefit details

Technical Implementation

New Components Created:

• FoodInsights.jsx - Main insights display with health scoring and detailed analysis
• AlternativesSuggestions.jsx - Modal dialog presenting healthier alternatives
• SeasonalRecommendations.jsx - Dynamic seasonal ingredient suggestions
• NutritionQualityIndicator.jsx - Visual progress bars for nutrient tracking
• EducationalTooltip.jsx - Interactive nutrition education tooltips
• NutritionBadge.jsx - Quick health grade display badges

Utility Functions:

• nutritionAnalysis.js - Core analysis algorithms with configurable health thresholds
• seasonalIngredients.js - Seasonal ingredient database and recommendation engine

Enhanced Existing Components:

• TemporaryDrawer.jsx - Integrated insights panel, alternatives button, and educational tooltips
• NutritionDashboard.jsx - Added daily nutrition insights with smart analysis

Example Usage

For a healthy meal (grilled chicken salad):

• Grade A (95/100): "Excellent nutritional choice!"
• Positive Aspects: Good Protein Source, Low Sodium, Well-Balanced Protein
• Educational Insight: "This meal's high protein content will help maintain stable blood sugar and keep you satisfied longer!"

For a high-sodium meal (processed sandwich):

• Grade C (55/100): "Decent choice, but consider healthier alternatives"
• Concerns: High Sodium, High Sugar, Very High Calories
• Alternatives: Use herbs and spices instead of salt, add fiber with vegetables, try grilling instead of frying

Integration with Existing Workflow

The feature seamlessly integrates with the current meal tracking process:

1. User uploads/takes photo of meal (existing flow)
2. Google Gemini AI provides nutrition data (existing flow)
3. NEW: Smart analysis generates insights and alternatives
4. NEW: Seasonal recommendations appear based on current season
5. User can view alternatives via new "Alternatives" button
6. User logs meal as before (existing flow)

Performance & Architecture

• Frontend-only implementation - No backend API changes required
• Efficient analysis - Processing happens client-side without additional API calls
• Modular design - Components are easily maintainable and extensible
• Responsive layout - Works seamlessly on desktop and mobile devices

Environmental Impact

The seasonal recommendations feature promotes sustainable eating by:

• Encouraging consumption of locally available, in-season ingredients
• Educating users about the environmental benefits of seasonal eating
• Supporting local agriculture through ingredient suggestions

This implementation successfully addresses all requirements in the original issue, providing users with intelligent nutrition coaching while maintaining the app's ease of use and performance.
