Transparent nutrition estimates

Nutrition Calculation Methodology

How recipe ingredients, gram weights, serving yields, food-composition data, and rounding are used to prepare estimated nutrition values.

What the Nutrition Numbers Mean

Calories, protein, carbohydrates, fat, fiber, sugars, saturated fat, and sodium shown on recipe pages are calculated estimates for the exact base-recipe weights displayed on that page. They are not laboratory results and should not be treated as exact values for every brand or kitchen.

Ingredient Weights and Serving Yield

Each base recipe assigns an edible gram weight to every ingredient included in the calculation. Optional ingredients are excluded unless the recipe explicitly says otherwise. The full-recipe totals are divided by the stated number of servings. Serving controls scale ingredient quantities for cooking convenience; the structured nutrition panel continues to describe the base serving.

Data Sources

Generic foods are aligned to the closest suitable entries from USDA FoodData Central or comparable standard food-composition information. Packaged products can differ substantially, so the exact Nutrition Facts label should be used when a reader needs a brand-specific estimate.

Calculation and Rounding

For each nutrient, the value per gram is multiplied by the ingredient weight. Ingredient contributions are added to produce a recipe total and divided by the serving yield. Display values are rounded for readability, so a rounded calorie number may not exactly equal a calculation made from the rounded protein, carbohydrate, and fat values.

Why Your Result May Differ

  • Brands and varieties can have different nutrition profiles.
  • Draining, trimming, cooking loss, and moisture changes alter final weight.
  • Household measures are less precise than a kitchen scale.
  • Substitutions, toppings, oils, sauces, and larger portions change the result.
  • Restaurant or prepared versions may not match a home recipe.

How Readers Can Check a Recipe

Use the gram weights listed on the recipe page, match each food to an appropriate database entry or package label, calculate each ingredient contribution, and divide by the stated yield. The ingredient-level breakdown on each recipe page is included to make that process easier to review.

Safety and Individual Needs

Nutrition estimates are for general education. People managing allergies, diabetes, kidney disease, pregnancy, eating disorders, medically prescribed diets, or other specific needs should seek individualized guidance from a qualified professional.
