    📐 Formula & Methodology: How Nutrition is Calculated

    This tool calculates nutritional values by scaling per-100g values based on your input:

    scaled_quantity = (input_quantity × unit_multiplier) / 100

total_calories += calories_per_100g × scaled_quantity
total_protein  += protein_per_100g × scaled_quantity
total_carbs    += carbs_per_100g × scaled_quantity
total_fat      += fat_per_100g × scaled_quantity

    Additional Details:

    • Unit Conversions: 1 tbsp ≈ 15g, 1 tsp ≈ 5g, 1 cup ≈ 240g (approximate)
    • Source: Swiss Food Composition Database (FDHA/FSVO)
    • Calories from macros: Protein & Carbs = 4 kcal/g, Fat = 9 kcal/g
    • Per Serving: Calculated by dividing the total values by number of servings entered

    🧮 Example: Grilled Chicken Salad Nutrition

    Ingredients:

    • Chicken breast: 200g
    • Olive oil: 1 tbsp
    • Romaine Lettuce: 100g
    • Tomatoes: 100g

    Result:

    • Total Calories: ~373 kcal
    • Protein: ~51.3g
    • Carbs: ~4.6g
    • Fat: ~16.1g
    • Per Serving (2 servings): ~186 kcal, 25.7g protein, 2.3g carbs, 8.1g fat

    Great for tracking macros or publishing a calorie-labeled recipe.

    ❓ Frequently Asked Questions (FAQ)

    How accurate is this nutrition estimator?

    We use official data from the Swiss Food Composition Database, scaled by your input. However, results are estimates—actual nutrition may vary depending on brand and cooking method.

    What does “per serving” mean?

    It’s the total nutritional breakdown divided by the number of servings you enter. Perfect for tracking individual portions.

    Can I use tablespoons, teaspoons, or cups?

    Yes! The tool converts those units to grams using standard approximations. For best accuracy, we recommend using grams or ml.

    What does the chart show?

    A visual pie chart that breaks down calories from protein, carbs, and fat—useful for balancing macronutrients at a glance.

    Can I enter custom ingredients?

    Not yet. You can select from our growing database. Support for custom foods is planned for future releases.

    Are vegetables and fresh items included?

    Yes. The database covers most common foods: vegetables, fruits, meats, dairy, grains, and oils.

    Can I export or print the results?

    Yes! Use the “Copy Results” or “Print/Export” buttons to save your breakdown or print a PDF.

    Is this tool mobile-friendly?

    Absolutely. It works on phones and tablets and is optimized for quick access while cooking.

    How are ml and g handled for different foods?

    The tool assumes equal density for simple conversions. For liquid vs solid differences, use grams for best precision.

    How are calories calculated from macros?

    Calories = (Protein × 4) + (Carbs × 4) + (Fat × 9). The pie chart is built using this formula to show calorie contribution from each macro.
