They all belong to sausage and bacon foods. Although sausages and bacon foods are delicious, they are not suitable for eating too much from a health perspective. First of all, the fat content in these foods is high, and eating more of them is not good for the human body. Secondly, a large amount of salt, preservatives, pigments, etc. are added during the processing of these foods. Eating too much of them is also bad for the body. In order to prevent the pickled products from deteriorating, the amount of salt will be particularly "enough". The longer the shelf life, the more added. In particular, polymeric phosphates are added. Eating too much phosphorus-containing food can easily lead to calcium deficiency in the human body.

Sausages and bacon are made differently in different places. Some are dried directly, and some are smoked. Everyone knows that smoked products are carcinogenic, so you should eat less bacon or sausages made using smoked methods. Of course, eating less does not mean you cannot eat them. Sausages and bacon are delicacies after all. As long as they are not eaten regularly, the harm will not be obvious.
