For those wondering what exactly counts as ultraprocessed:

“ from protein bars to diet soda, from cold cuts to packaged bread — and often contain "additional ingredients like artificial colors and flavors, preservatives, and other ingredients to preserve their texture and longevity”

Conversely, Miller notes that some technically ultraprocessed foods, like liquid egg whites, raisins and unsweetened raisins are actually quite “good for you,” so it’s challenging to generalize too much.

So they’re bad, but not all of them are bad and don’t generalize too much.
