Data Sources & Methodology

Data source: USDA FoodData Central.

Reverse computation method: The food amount required to reach a macro goal is calculated as goal_g / (macroPercentage / 100), where macroPercentage = fatPer100g. For volume output, the resulting gram weight is divided by the food's density.

Accuracy note: Macro values represent averages across measured samples; individual items may vary ±5–10% depending on brand, farming method, and preparation technique. For clinical nutrition, consult a registered dietitian.

Update policy: Macro values are reviewed quarterly against USDA FoodData Central updates. Page last verified: 2026.
