- The idea of limiting salt and fats in the diet comes from very misguided health recommendation based on bad science from the 70s motivated by commercial reasons.
- Bacon actually has quite a healthy lipidic profile even with those recommendations (50% monounsaturated rich in Oleic acid, like olive oil; not that saturated fat is actually unhealthy...)
- Same for nitrates; bacon doesn't even have that much, nitrates are not proven to be harmful and most of nitrites/nitrates are endogenous (70-90%) anyway...
