Seeing the name calcium propionate in the ingredients of your bread would make anyone raise an eyebrow.
But, in fact, this substance is considered very safe.
In case you’re wondering, calcium propionate is used as a preservative in bread to prevent mold and microorganisms.
This means that the bread will last longer. In one study, rats were fed this preservative for a year and showed no negative signs.
Naturally, calcium propionate is FDA approved and is even used by home bakers.
Sodium nitrate is another preservative used to cure meats. There have been claims that sodium nitrate can cause heart disease and cancer.
However, as with sodium nitrite, heart disease and cancer can be avoided with sodium nitrate.
By eating small portions of these cured meats, the benefits associated with sodium nitrate—such as lower blood pressure – can occur.
Even with the potential negative effects, sodium nitrate is considered safe in meats.
