How the numbers are calculated

The AI only reads your words. It never invents nutrients. Each food is matched to a record from USDA FoodData Central, the Canadian Nutrient File or a package label, and the totals are plain arithmetic.

Open a meal and tap How was this calculated? to see, for each item:

1. the record it matched,
2. the per-100 g value,
3. the grams, and
4. the multiplication.

Sourdough bread   272 kcal/100 g × 64 g = 174 kcal

Goals and totals are estimates, not medical advice.
