Is dried fish still nutritious?

The nutritional value of fish is very rich. Many people like to make fresh fish into dried fish, and when they want to eat it, take it out and soak a few pieces of dried fish to make all kinds of delicious food. Then, what are the main nutritional values of dried fish with fresh fish?

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. When protein food is lacking in dinner, or bread, cold noodles and instant noodles are used to satisfy hunger, adding dried fish as snacks can effectively supplement nutrition. Eating properly while traveling is also conducive to maintaining physical fitness. 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 high-energy food. Eating more is no different from eating more meat. Nowadays, 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, shredded squid and other foods contain more "nitrosamines", which are 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.

4, increase salt, in order to facilitate storage, dried fish have added a lot of salt, eating will bring extra sodium, which is very unfavorable to chronic patients, and may also aggravate edema, eye bags and premenstrual discomfort.
