Canned or Pitted Olives?

The debate over whether canned or pitted olives are more poisonous has been a contentious one for many years. On one hand, canned olives are convenient and easy to store, making them a popular choice for many people. On the other hand, pitted olives may contain toxic metals and other contaminants due to the processing they undergo.

This lye treatment can cause the canned olives to taste overly salty or bitter, and it can also cause them to contain high levels of sodium. Additionally, during the canning process, some nutrients can be lost from the olive itself.

Pitted olives often require more processing than canned olives and may contain higher levels of toxic metals such as lead and cadmium.

In conclusion, black olives are not poisonous. They are a nutritious addition to many dishes and can provide important health benefits.
