Reviewed by Calculator Editorial Team
This calculator helps you determine the calorie content and nutritional facts of food items based on serving size and ingredient information. It's based on standard nutrition labeling principles and provides a quick way to estimate nutritional values for various food products.
How to Use This Calculator
To use the Discovery Health Nutrition Facts Calorie Calculator:
- Enter the serving size of the food item in grams or ounces
- Input the total calories per serving
- Provide the amount of fat, carbohydrates, and protein per serving
- Click "Calculate" to see the complete nutrition facts panel
- Review the results and compare with standard nutrition guidelines
Note
This calculator provides estimates based on standard nutrition labeling. For precise values, always refer to the actual nutrition facts label on packaged foods.
Formula Used
The calculator uses the following formulas to determine nutritional values:
Calories from Fat
Calories from fat = (Fat in grams) × 9
Calories from Carbohydrates
Calories from carbohydrates = (Carbohydrates in grams) × 4
Calories from Protein
Calories from protein = (Protein in grams) × 4
Total Calories
Total calories = Calories from fat + Calories from carbohydrates + Calories from protein
The calculator also calculates the percentage of daily values based on standard USDA guidelines for a 2,000 calorie diet.
Worked Example
Let's calculate the nutrition facts for a 100g serving of a food item with:
- Total calories: 250 kcal
- Fat: 8g
- Carbohydrates: 30g
- Protein: 5g
Using the formulas:
- Calories from fat = 8 × 9 = 72 kcal
- Calories from carbohydrates = 30 × 4 = 120 kcal
- Calories from protein = 5 × 4 = 20 kcal
- Total calories = 72 + 120 + 20 = 212 kcal (matches the input)
The calculator would display these values along with daily value percentages.
Interpreting Results
The nutrition facts panel includes:
- Serving size - The amount of food being analyzed
- Calories - Total energy content
- Fat content - Total fat and saturated fat
- Carbohydrates - Total carbohydrates and fiber
- Protein - Total protein content
- Daily values - Percentage of recommended daily intake
Key interpretation guidelines:
- 5% or less of calories from saturated fat is considered healthy
- Less than 300mg of sodium is ideal for heart health
- More than 5g of fiber per serving is beneficial
- Daily values over 20% indicate higher content of that nutrient
