This MCP server provides high-precision nutritional analysis by aggregating macronutrients and micronutrients from food items. Using USDA FoodData Central reference values, it calculates exact totals for calories, proteins, fats, carbohydrates, and a wide array of vitamins and minerals. Users can use calculate_meal_nutrition to sum totals for multiple items, calculate_daily_value_percentages to see how a meal fits into a 2,000 kcal diet, and get_food_reference_data to inspect individual food profiles. It handles complex unit conversions like ounces to grams and cups to milliliters automatically.
