Frequently asked questions
Is bacon or sausage more processed?
They score about the same in our analysis. Bacon is cured and smoked pork belly; sausage is ground meat with spices and preservatives. Commercial versions of both typically include sodium nitrite.
What does uncured bacon mean?
Uncured bacon is still cured, just with celery powder, a natural source of nitrates, instead of synthetic sodium nitrite. It scores similarly in our analysis because the underlying process is the same.
