Why every time i eat salami it gives me diarrhea?

There are a couple reasons why salami might be giving you diarrhea.

1) Salami is a fermented meat. This means that it contains bacteria that help to preserve it. Some people are sensitive to these bacteria and may experience digestive problems such as diarrhea.

2) Salami is high in fat and protein. These can be difficult for some people to digest, especially if they are not used to eating a lot of them.

3) Salami may be contaminated with bacteria or parasites. This can happen if the salami is not properly handled or stored.

4) You may be intolerant/allergic to a certain ingredient. It's important to check if salami contains any components you may not tolerate or be allergic to.

If you experience diarrhea after eating salami, it is best to avoid it in the future. You may also want to see a doctor to rule out any other possible causes.
