Why can fish be eaten? Can this fish be eaten?

Usually, fish is a delicacy on our table. Whenever there is a festive season, or to entertain friends and family, or to improve the food during the holidays, there will always be fish on the table. Fish meat is tender and delicious, nutritious, easy to digest, and has some advantages that animal meat cannot match, so it has become one of the most popular non-staple foods of people.

However, the benefits of fish in preventing diseases are less well known. According to studies in recent years, fish is an extremely beneficial food for human health, especially for the prevention of the occurrence of coronary heart disease and coronary heart disease patients. Recently, a foreign study published the incidence of atherosclerosis and coronary heart disease, with the highest incidence in Europe and the United States, the lower incidence in the Japanese in Asia, and almost no atherosclerosis and coronary heart disease in the Arctic.

Medical scientists have found that the most significant difference in the diets of people in these three regions is that Eskimos eat the most fish, while Europeans and Americans eat less fish this day. According to the information published:

The average Eskimo eats 400 grams of fish per day, the average Japanese eat 200 grams of fish per day, and the average Europeans and Americans eat 100 grams of fish per day. Take Japan as an example: the number of people living in Okinawa is much lower than that of the Japanese mainland, and they eat twice as much fish per day as the Japanese mainland.

Experts have found that the more fish you eat in your three meals a day, the less chance you have of coronary heart disease. So, why can fish foods reduce the incidence of coronary heart disease? Scientists have analyzed the composition of fish meat and found that fish fat is rich in N-fatty acid, an essential fatty acid with a unique effect.

Essential fatty acids are a kind of fatty acids that cannot be synthesized in the human body, rely on the relevant food supply, and cannot be lacking in the structure and function of the human body. The high content of n-3 fatty acids in fish fat is incomparable to other foods, and its role in preventing atherosclerosis and coronary heart disease is very prominent, and it can be called the star of lipid reduction. Therefore, it is very necessary and advantageous to appropriately increase some fish in the daily diet and eat more fish foods.

Especially for patients with coronary heart disease and middle-aged and elderly people, for your health, eat more fish.
