+# Nutrition Analysis API
+
+## Overview
+A Python FastAPI backend system that provides comprehensive nutritional analysis and health recommendations. The system manages user authentication with role-based access (admin and normal users), product database management, health issue tracking, and AI-powered nutritional analysis using OCR and Google's Gemini API.
+
+## Features
+
+### Authentication & User Management
+- **Role-Based Access Control**: Admin and normal user roles
+- **JWT Token Authentication**: Secure authentication using JSON Web Tokens
+- **User Registration & Login**: Email and username-based registration
+- **Password Security**: Bcrypt password hashing
+
+### Admin Capabilities
+- Add products with complete nutrition facts to the database
+- List all products in the system
+- Delete products from the database
+
+### User Features
+- Manage personal health profile
+- Add/track health issues (diabetes, hypertension, cholesterol, etc.)
+- View and manage health issue records
+- Upload nutrition label images for analysis
+
+### AI-Powered Nutrition Analysis
+- **OCR Processing**: Extract nutrition facts from images using Tesseract OCR
+- **Gemini AI Integration**: Analyze nutrition data with Google's Gemini API
+- **Health Rating**: Products rated on a 1-10 scale based on nutritional value
+- **Personalized Recommendations**: Health-specific advice based on user's tracked health issues
+- **Alternative Suggestions**: Healthier product alternatives from the admin database

+## Database Schema
+
+### Users Table
+- id, username, email, hashed_password, role (admin/user)
+
+### Products Table
+- id, name, brand, calories, protein, fat, carbohydrates, sodium, sugar, fiber, cholesterol, serving_size
+
+### Health Issues Table
+- id, user_id (FK), issue_type, severity, notes
+
+## API Endpoints
+
+### Authentication
+- `POST /auth/register` - Register new user
+- `POST /auth/login` - Login and get JWT token
+- `GET /user/me` - Get current user info
+
+### User Health Management
+- `POST /user/health-issues` - Add health issue
+- `GET /user/health-issues` - List user's health issues
+- `DELETE /user/health-issues/{id}` - Delete health issue
+
+### Admin Product Management
+- `POST /admin/products` - Add new product (admin only)
+- `GET /admin/products` - List all products (admin only)
+- `DELETE /admin/products/{id}` - Delete product (admin only)
+- `POST /admin/users/{user_id}/promote` - Promote user to admin role (admin only)
+
+### Nutrition Analysis
+- `POST /nutrition/analyze` - Upload image for nutrition analysis
+
+## Environment Variables
+
+- `SESSION_SECRET` - JWT secret key (auto-configured by)
+- `GEMINI_API_KEY` - Google Gemini API key (required for AI analysis)
+
+## Security Notes
+
+### Creating Admin Users
+For security, all new user registrations default to normal user role. To create admin users:
+1. Register a regular user account via `POST /auth/register`
+2. Manually promote the user to admin using one of these methods:
+   - Use an existing admin account to call `POST /admin/users/{user_id}/promote`
+   - Directly modify the database to set the first admin (SQLite: `UPDATE users SET role='admin' WHERE id=1;`)
+3. Once you have at least one admin, use the promotion endpoint for additional admins
+
+### Production Deployment
+- Ensure `SESSION_SECRET` is set to a strong, random value in production
+- Keep `GEMINI_API_KEY` secure and never expose it in client-side code
+- Consider adding rate limiting for authentication endpoints
+- Regularly audit admin user accounts
+
+## Recent Changes
+
+- **2025-11-17**: Initial project setup with complete FastAPI backend implementation
+  - Configured SQLite database with SQLAlchemy ORM
+  - Implemented secure JWT-based authentication system with role-based access control
+  - Created admin and user role-based endpoints
+  - Integrated Tesseract OCR for nutrition label extraction
+  - Added Gemini API integration for AI-powered analysis
+  - Set up comprehensive error handling and validation
+  - Fixed critical security vulnerability: removed self-service admin role assignment
+  - Added admin-only user promotion endpoint
+
+## Technology Stack
+
+- **Framework**: FastAPI
+- **Database**: SQLite with SQLAlchemy ORM
+- **Authentication**: JWT (python-jose) + bcrypt
+- **OCR**: Tesseract + pytesseract
+- **AI**: Google Gemini API
+- **Image Processing**: Pillow
+- **Server**: Uvicorn ASGI server
