NutriLens: Food Health Impact Analyzer
Snap a photo of your meal, grocery label, or type a list of ingredients. NutriLens identifies each ingredient, looks up real nutritional data from the USDA, finds relevant scientific studies on PubMed, and delivers a clear per-ingredient health breakdown with proper citations.
Works with food labels in any language.
Why this exists
Most of us buy food every day without really knowing what's in it or what it does to our bodies. Ingredient lists are full of names that sound foreign even in our own language - "sorbitol syrup," "soya lecithin," "emulsifier" - and nutrition science lives in dense academic papers most people will never read.
That gap matters: the foods we eat regularly shape our long-term health, and a lot of that influence is invisible until it's added up over years. NutriLens exists to close that gap - to take what's already known and published and turn it into something anyone can read in a minute, in plain language, before they decide what to put in their cart or on their plate.
The goal isn't to scare anyone away from a treat or declare foods "good" or "bad." It's awareness: knowing what you're consuming, what the science actually says about it, and why - so you can make your own informed choices.
How it works
- Identify: A small vision-language model reads your food photo or label and extracts the ingredients.
- Look up: Each ingredient is matched against the USDA FoodData Central database for verified nutritional data.
- Research: PubMed is searched for recent scientific reviews on each ingredient's health effects.
- Analyze: The model synthesizes the nutritional data and study findings into a clear, evidence-based health report with citations.
When databases are rate-limited, the model falls back to its own knowledge and clearly labels those sections.
