How do I log a banana in Tone?
Say it the way you’d tell a friend, with how much you had. Tone knows it as “banana”, “bananas” or “frozen banana”. Leave the amount out and it uses a typical portion, which you can change before it’s logged. It’s a Tone Verified food, so the record and portions were picked by a person.
Where do these numbers come from?
From the USDA’s record “Banana, raw”, in the USDA Food and Nutrient Database for Dietary Studies (FNDDS). Daily Values are the FDA’s for adults. Burn times use the 2024 Compendium of Physical Activities and count everything burned during the activity, including what your body would burn at rest anyway. Cooking, brand and size change the numbers, so treat them as typical rather than exact.
