How to Calculate Nutrients for Any Serving Size
Divide your actual serving by the label serving to get a ratio, then multiply each nutrient by that ratio.

Ratio = Your Serving / Label Serving
Your Nutrient = Label Nutrient x Ratio

Häufig Gestellte Fragen
Why are nutrition labels based on small servings?
Serving sizes are set by regulation (RACC - Reference Amounts Customarily Consumed) and sometimes appear small compared to what people actually eat.
Do I need a food scale?
A kitchen scale is the most accurate way to measure serving size. Estimating by volume (cups) works for some foods but is less precise, especially for calorie-dense items.
How do I calculate for packaged foods with multiple servings?
The label shows nutrients per serving and servings per container. Multiply per-serving values by the number of servings you eat.
