# SmartPlate – AI Nutrition Assistant

Photograph your meal and get instant nutritional analysis with evidence-based health advice from WHO, DGE, and Harvard guidelines.

## How it works

1. 📷 **Computer Vision** — A Vision Transformer (ViT) fine-tuned on Food-101 classifies the dish (20 classes, 96.46% accuracy)
2. 🔢 **ML Numeric** — Logistic Regression classifies the dish as healthy/medium/unhealthy based on nutritional values (100% test accuracy)
3. 💬 **NLP RAG** — OpenAI gpt-4o-mini generates evidence-based advice from a vector store (ChromaDB) of WHO/DGE/Harvard nutrition guidelines

## Supported food classes

Healthy: caesar_salad, greek_salad, edamame, miso_soup, grilled_salmon
Medium: sushi, sashimi, spaghetti_bolognese, pad_thai, chicken_curry, omelette, pancakes, ramen
Unhealthy: pizza, hamburger, french_fries, donuts, cheesecake, ice_cream, chocolate_cake
