Inspiration

As a group of international students, we often struggle to maintain a healthy diet amidst our busy schedules. With packed lectures, assignments, and social commitments, we tend to rely on pre-packaged, ready-to-eat meals. However, understanding nutrition labels can be confusing, and misleading claims, hidden ingredients, and a lack of personalized guidance make it even harder to make informed food choices. Our inspiration came from the common challenge faced by students—balancing convenience with healthy eating. We wanted to develop a solution that leverages AI to decode nutrition labels, expose misleading claims, and offer personalized health insights. By simplifying nutritional awareness, we aim to empower students to make better dietary decisions effortlessly, helping them stay healthy while managing their academic and personal lives.

What it does

The Nutrition Analyzer is a smart web application that allows users to: Upload an image of a nutrition label to extract key details using AI. Input dietary preferences and allergies for personalized analysis. Get an instant health classification—healthy, moderately healthy, or unhealthy. Receive detailed nutritional summaries, including calories, macronutrients, and ingredients. Get allergy warnings based on user input. View daily intake recommendations for better dietary decisions.

How we built it

Image Processing & AI: We used machine learning models (such as DistilBERT) to extract text from nutrition labels and analyze them. Web Application: The front-end was built using React, while the back-end leverages Python & Flask for AI processing. Health Classification Algorithm: We implemented a system to categorize food items based on extracted nutritional data. Database Integration: A dataset of nutritional information was used to enhance analysis and provide comparisons.

Challenges we ran into

Accurate Text Extraction: Some nutrition labels had low-quality prints, complex fonts, or blurry images, making OCR-based extraction challenging. Classification Complexity: Defining precise health thresholds for classifying food as healthy or unhealthy required extensive data validation. Personalization Handling: Implementing custom dietary preferences while maintaining accurate health assessments was a balancing act. Real-Time Processing: Ensuring fast and accurate analysis without lag was a performance challenge.
