Eating pickles can regulate appetite, enhance appetite and supplement dietary fiber, but it also has many health risks. When fresh vegetables are pickled, the vitamin C contained in them will almost be destroyed by the whole army, so the nutritional value of pickled vegetables is far lower than that of fresh vegetables. What's more, pickles contain more nitrite, which will generate carcinogenic nitrosamines after entering the human body, so that people always have worries when eating.
