Protein, calcium, phosphorus, iron and other minerals, as well as a large number of cephalin, which are rich in roe, are extremely important to human body, especially to children's growth and development, and these nutrients are often easily lacking in our daily diet.
Especially cerebrolysin, which is the basic substance of brain and nerve development, can promote brain development and improve intelligence level, and is beneficial to enhance memory and cognitive ability. Once lacking, nerve cells will be damaged and brain function will be disordered, which will affect advanced cognitive functions such as memory and thinking.
Although fish can be divided into fresh water and seawater, the nutritional composition of roe is not much different. Japanese scientists studied the roes of 18 species of Pacific fish, and found that the contents of protein and total lipid in roes were higher than those in fish, but the water content was less. In other words, the nutritional value of roe is not lower than that of fish in some aspects, but higher than that of fish.
Extended data:
Although the roe is very small, it is difficult to digest it after eating, and it is also difficult to cook it thoroughly. After eating it, it is easy to digest and cause diarrhea. Caviar, as long as we cook it thoroughly in the cooking process, don't eat too much when eating. Caviar will not only affect intellectual development, but also help improve intellectual development and health.
It should be noted that some roe, not all roe, can be eaten. For example, puffer fish roe is poisonous and must not be eaten. If it is not handled properly, it can directly kill people (one puffer fish roe can poison dozens of adults). Catfish (catfish) roe is also toxic. Eating it by mistake can lead to vomiting, abdominal pain, diarrhea and dyspnea, and in severe cases, paralysis.
But eat less fish in polluted areas. Because the pesticide residue in fish head and roe is five to ten times higher than that in fish. Therefore, you should choose healthy and pollution-free caviar. In addition, you should eat everything in moderation. The cholesterol and protein of fish roe are high, and excessive consumption is not conducive to absorption.
