Calculate the amount you actually ate

For a measured 150 g of this same food and form: 588 × 150 ÷ 100 = about 882 kcal. Use the per-100-g value with your actual weight; a piece or bowl in the table is only a starting estimate.

Check the USDA description above before choosing a match. Raw, cooked and dry entries are not interchangeable, and a branded or mixed dish may have different ingredients. Missing nutrients are not zero. Read our sources and calculation method.
