How to read it
- Foods. Walnuts is FNDDS’s “Walnuts, excluding honey roasted” and pecans is “Pecans, unsalted”, the same foods and numbers Calorie Tape shows.
- Serving. One of FNDDS’s own portions, the one nearest the amount FNDDS assumes when someone doesn’t say how much they ate.
- Checks. A check marks whichever food has more of a nutrient. More isn’t better or worse, just more. Amounts that round to the same number get no check.
Every one of these nutrients, in your log
Calorie Tape logs these same USDA foods with all 65 nutrients, offline, and shows which foods your day’s potassium, fiber or iron came from. No account, and your log stays on your iPhone.
