How Sloe works, nutrition methodology, data sources, and disclaimers.
When you import a recipe, Sloe parses every ingredient and matches it against multiple food databases:
- Ingredient parsing — each line is broken into name, quantity, and unit. Count-based items (e.g. “2 eggs”) are converted to gram weights using our staples database of 176+ common foods.
- Database matching — each ingredient is searched against USDA FoodData Central, Open Food Facts, and FatSecret. The best match by name similarity and portion plausibility is selected.
- Confidence scoring — each ingredient receives a score (0–100%). High means the match closely aligns with a verified database entry. Low means it fell back to a local estimate. Tap any ingredient on a recipe to see its score and source.
- Aggregation — per-ingredient macros are summed and divided by servings to produce per-serving totals.
