DesiDiet AI: Personalized Nutrition at Scale

DesiDiet AI is an enterprise-grade nutritional ecosystem designed specifically for the Bangladeshi population. It leverages a modern GraphRAG (Graph-based Retrieval-Augmented Generation) architecture to deliver highly personalized dietary advice grounded in the National Dietary Guidelines (NDG) Bangladesh 2025.

🛠️ System Overview

DesiDiet AI follows the Infinity AI Buildfest 2026 AI-Native Application Blueprint. It consists of three primary layers:

  1. Data Layer: Neo4j Knowledge Graph (370+ local foods & NDG rules) + Prisma SQL (User profiles & logs).
  2. Reasoning Layer (FastAPI): Python-based GraphRAG engine that performs semantic retrieval and dietary constraint checking.
  3. Presentation Layer (React): A premium, bilingual dashboard for real-time AI assistance and health tracking.

For a comprehensive breakdown of our 8-layer enterprise architecture, please see the System Architecture Documentation.

Quick Start

1. Database (Neo4j)

Run the Neo4j graph database locally using Docker:

docker run -d --name neo4j-khadok \
    -p 7474:7474 -p 7687:7687 \
    -e NEO4J_AUTH=neo4j/khadok2025 \
    neo4j:5.12

2. Backend & GraphRAG Engine

cd graphRAG
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

# Ingest data into Neo4j
python3 preprocessing/clean_csv.py
python3 build_graph.py

# Start the API server
uvicorn app.main:app --reload

3. Frontend Dashboard

The frontend is a modern React application.

cd frontend
npm install
npm run dev

Detailed instructions are in the Frontend README.

Knowledge Graph & Schema

The system utilizes a hybrid model to link nutritional science with user data.

Database Schema

Core Logic:

  1. IBW & Macro Targeting: Automatic calculation of Ideal Body Weight and caloric goals.
  2. Constraint Propagation: The Graph engine traverses from MedicalCondition → DietaryRule → FoodGroup to filter unsafe items.
  3. LLM Reasoning: Integrates with local/remote LLMs to synthesize culturally accurate meal suggestions.
