1. With the decrease of water content, the nutrients in dried fish are concentrated, and the protein content is as high as 45%. Therefore, they are good food to supplement protein. However, a large amount of protein contained in dried fish is only beneficial to human body to a certain extent. If there is too much protein, which exceeds the utilization capacity of human body, a series of metabolic wastes such as ammonia and urea will be formed in the body, which will increase the burden on liver and kidney. Protein, which can't be digested and absorbed, will promote the reproduction of intestinal spoilage bacteria, and form fecal odor and even carcinogens in the intestine.

2. Dried fish is a kind of food with high heat energy. Dried fish contains a lot of fat. Eating more is not good for losing weight, and it will also increase the intake of saturated fatty acids.

3. Dried fish contains more "nitrosamines", which is a strong carcinogen and the result of the combination of protein decomposition products and nitrite. Occasionally, eating a small amount will not cause harm, but if you often eat a lot of dried fish or the raw materials for processing dried fish are not fresh, it is likely to lead to excessive intake of nitrosamines.

Step 4 add salt. In order to facilitate storage, a large amount of salt is added to dried fish, which will bring extra sodium when eaten, which is very unfavorable to chronic patients and may also aggravate edema, eye bags and premenstrual discomfort.

Moreover, it is important that dried fish amenorrhea is a pickled food, so there will be carcinogens, and it is absolutely impossible to eat more.
