How does Chronometer calculate protein %age for individual foods?
I decided to calculate the protein %age for broccoli, and the data I got from the USDA does match the data in Chronometer’s USDA broccoli entry. But I calculated 29% protein while Chronometer calculates 20% protein.
My method was to start with the (rounded) data:
Then I took the protein and divided it by sum of all 3 macros. Then multiply by 100 to get the percentage.
Is this approach correct? How does Chronometer do it?
I’m using broccoli as a generic example and assuming I will run into similar variation in other foods. I’m considering increasing my protein intake from 10-15% to 20-25%, so I’m a little concerned that I don’t understand why my calculations are 9% off of Chronometer’s despite using the same data.
Thanks for the help!
