The nutritional value of squid is not inferior to that of beef and tuna. Every 100 grams of dried squid contains 66.7 grams of protein and 7.4 grams of fat, and contains a lot of carbohydrates and inorganic salts such as calcium, phosphorus and sulfur. The content of protein in fresh squid is as high as 16%~20%, and the fat content is very low, only about 4% of that of ordinary meat, so the calories are far lower than that of meat food. For people who are afraid of obesity, 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 quite effective in preventing the formation of 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 content of cholesterol 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 the food intake is above 2, the cholesterol in the 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 normally used by the human body and will not be accumulated in the blood. The cholesterol in the body is mostly concentrated in its internal organs. There is no need for people to worry about the increase in cholesterol intake caused by eating squid.
