✨ AI-Powered Features

NutriTrack uses the Google Gemini API to deliver intelligent health insights:

• AI Health Report Analysis: Upload your PDF health reports. The AI reads the document, provides a simple summary, and automatically extracts a list of critical foods/ingredients to avoid.
• AI Personalized Diet Planning: Based on your height, weight, age, lifestyle, and goals, the AI calculates your optimal daily calorie and macronutrient requirements.
• AI Nutritional Lookup: Instantly get a detailed nutritional breakdown (calories, protein, carbs, fats) for any food or custom recipe you log.
• AI Dietary Alerts: The system cross-references your food logs against your personalized "avoid list" and warns you if a food contains something you shouldn't eat.
