alt Hacker NewsI think of “UPF” the way I think of “BMI.” Useful insofar as it provides an intial signal for further investigation. The term UPF provides a way to group certain foods according to their likelihood of helping me reach my health goals.
I don’t need a term to be perfect to be useful.
I think people's intuition is generally reliable, though. What food has the term "UPF" helped you learn is 'unhealthy', which you otherwise would have thought of as healthy?
For losing fat, "fried chicken", "chocolate cake", and "sugary drinks" are intuitively unhelpful, and "vegetables", "lean meat", "water" is more "healthy".
