Household weights come from the app’s portion table, not necessarily USDA. Rows marked App estimate are estimates; your portion may differ. A serving is not a recommended amount to eat.

Calculate the amount you actually ate

For a measured 150 g of this same food and form: 29 × 150 ÷ 100 = about 44 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.

Log it in seconds. In BiteJot AI you can say or type “lemon”, or scan or snap it, then confirm the amount. Calories always come from a database like this one, never from the AI.
