## Overview

This is a role-based nutrition and wellness platform: users track meals and health metrics, review plans and progress, and connect with dietitians; dietitians manage patients and plans, while administrators manage accounts, approvals, food data, and reporting. The backend exposes these capabilities through authenticated API routes backed by PostgreSQL. The route mounts and sampled controller responsibilities support the backend relationships shown; frontend pages indicate the product areas, but their API wiring was not sampled, so no UI-to-API calls are asserted.

Main entry points: [`Backend/src/config/db.js`](https://github.com/fatema-rifa03/smart-health-diet-recommendation/blob/main/Backend/src/config/db.js) (PostgreSQL connection), [`Backend/src/app.js`](https://github.com/fatema-rifa03/smart-health-diet-recommendation/blob/main/Backend/src/app.js) (Express API), [`Backend/src/middleware/auth.middleware.js`](https://github.com/fatema-rifa03/smart-health-diet-recommendation/blob/main/Backend/src/middleware/auth.middleware.js) (Authentication guard), [`Backend/src/routes/tracking.routes.js`](https://github.com/fatema-rifa03/smart-health-diet-recommendation/blob/main/Backend/src/routes/tracking.routes.js) (Tracking routes)
