First of all, some unscrupulous traders add nitrite to pickled chicken feet. Nitrite is a "frequent customer" of pickled products, so it is cheap and has sufficient salt, so many people will add this kind of substance to pickled products in order to save costs. However, nitrite is harmful to human body, and the biggest harm is cancer, so try to eat less pickled foods such as pickled peppers and chicken feet.

Secondly, the chicken feet with pickled peppers sold in the market are generally white and beautiful. In fact, this is the result of bleaching with bleach such as "hydrogen peroxide". Strong oxygen bleach is harmful to human body, which will damage our lung function and kidney function, so we'd better stay away from those chicken feet that look perfect.

In addition, the pickled chicken feet sold in the market all contain preservatives, which can ensure that they will not deteriorate after long-term storage, but they will be harmful to the health if they are eaten frequently.
