1. Squid is rich in calcium, phosphorus and iron, which is good for bone development and hematopoiesis, and can effectively treat anemia;


2. In addition to protein and amino acids, squid also contains a lot of taurine, which can inhibit cholesterol content in blood, relieve fatigue, restore vision and improve liver function;


3. Its polypeptide and selenium have antiviral and anti radiation effects;


4. Professor Wang Cunxin, Institute of Oceanography, Chinese Academy of Sciences, said that cholesterol can be divided into low-density and high-density. The cholesterol in squid is mainly high-density, which is beneficial and harmless to human body. The structure of the fat in squid is different from that in livestock and poultry;


5. It contains protein, omega-3 fatty acid, copper, zinc, B vitamins and iodine. B vitamins help relieve migraine and phosphorus helps calcium absorption. 100 grams of squid has only 70 kcal of energy. Note: do not eat more than one fist of squid every day. It is better not to fry.


According to traditional Chinese medicine, squid has the functions of nourishing yin and stomach, nourishing deficiency and moistening skin.


Its nutritional value is no less than beef and tuna. Every 100 grams of dried squid contains 66.7 grams of protein and 7.4 grams of fat, as well as a lot of carbohydrates and inorganic salts such as calcium, phosphorus and sulfone. The protein content of fresh squid is also as high as 16% ~ 20%, and the fat content is very low, only about 4% of the general meat, so the calories are far lower than the meat food. For people who are afraid of being fat, eating squid is a good choice. There is a high content of taurine. Eating squid can effectively reduce the cholesterol accumulated in the blood vessel wall, which is very effective in preventing the formation of vascular sclerosis 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 old people who are prone to cardiovascular diseases.


According to the research of modern medicine, although the content of cholesterol in squid is high, there is a substance taurine in squid at the same time, and taurine can inhibit the accumulation of cholesterol in blood. As long as the ratio of taurine to cholesterol is more than 2, the blood cholesterol will not rise. The content of taurine in squid was higher, the ratio was 2.2. Therefore, when eating squid, cholesterol is only normally used by the human body, and will not be accumulated in the blood. Most of the cholesterol in the body is concentrated in its internal organs. There's no need to worry about the increased cholesterol intake caused by squid consumption.
