Squid has high nutritional value. It is rich in protein, calcium, taurine, phosphorus, vitamin B 1 and other nutrients needed by human body, with extremely high content. In addition, the fat content is extremely low.

According to the data of China Fisheries Association Ocean Branch, squid has the advantages of high protein, low fat and low calorie, and its nutritional value is not inferior to beef and tuna. Every100g of dried squid contains 66.7g of protein and 7.4g of fat, and contains a lot of carbohydrates and inorganic salts such as calcium, phosphorus and sulfur. The protein content of fresh squid is as high as 16% ~ 20%, and the fat content is extremely low, which is only about 4% of that of ordinary meat, so the calories are far lower than those of meat food. Eating squid is a good choice for people who are afraid of obesity. Squid is not only rich in protein, calcium, phosphorus, iron and trace elements such as calcium, selenium, iodine and manganese, but also rich in highly unsaturated fatty acids such as DHA (commonly known as brain gold) and EPA, as well as high content of taurine. Eating squid can effectively reduce the cholesterol accumulated on the blood vessel wall, which is quite effective in preventing arteriosclerosis and gallstones. At the same time, it can supplement brain power and prevent Alzheimer's disease. Therefore, squid is a healthy food for middle-aged and elderly people who are prone to cardiovascular diseases.
Modern medicine has found that although the cholesterol content in squid is high, it also contains a substance-taurine, which can inhibit the accumulation of cholesterol in blood. As long as the ratio of taurine to cholesterol in food is above 2, the cholesterol in blood will not increase. However, the content of taurine in squid is higher, and its ratio is 2.2. Therefore, when eating squid, cholesterol is only used normally by the human body and will not accumulate in the blood. Professor Xin from the Institute of Oceanography, Chinese Academy of Sciences said that cholesterol can be divided into low density and high density, and the cholesterol in squid is mainly high density, which is beneficial to human body. The structure of fat in squid is obviously different from that of livestock and poultry, and the cholesterol in squid is mostly concentrated in its internal organs. There is no need to worry that eating squid will increase cholesterol intake.
