Why do you eat fish healthily and longevity?
Eskimos living in the snow and ice rarely suffer from cardiovascular disease and cerebral thrombosis. After decades of research, it was discovered that their main food was the mackerel in the sea. When the American scientific team visited the Eskimos in places such as Glen island, they found that there were two important substances in their platelets--- coagulation acid and prostaglandin. The former has a coagulation effect, while the latter has a vasodilating and anticoagulant effect. As people grow older, the synthesis of the latter decreases, the former increases, and it is easy to form blood clots, which is one of the reasons why the elderly are prone to arteriosclerosis and heart and cerebrovascular diseases.
The Eskimos eat blue croaker contain a large amount of eicosane pentasylic acid, which is an essential raw material for the synthesis of prostacycline in the human body, and the agglutination ability of platelets in the blood of those who eat blue croakers is low. An increase in prostaglandin in the blood is the main cause of cardiovascular and cerebrovascular disease in Eskimos.
In the meat of river fish and marine fish, the content of protein is large and of high quality. 500 grams of fish contains the same protein as 600 grams of eggs or 850 grams of pork. The chemical composition of fish meat is very similar to the chemical composition of human muscles. The amino acid composition in proteins is also similar to that of the human body. Vitamin A, D.BB and minerals potassium, sodium, calcium, magnesium, and phosphorus in fish are far superior to other meats. Marine fish meat is also rich in iodine and trace elements, diamonds, manganese and so on.
Having these essential nutrients in the human body can delay the aging process of organ cells. The meat of the fish is delicate and tender, the most easily digested and absorbed, and the absorption rate can reach 96%. Compared with other animal meats, its most prominent advantage is that there are 70% to 80% unsaturated fatty acids in the fats it contains, mainly linoleic acid, which is an essential fatty acid. This fatty acid cannot be synthesized in the body and must be obtained through food.
Studies have shown that people with heart disease who eat fish twice a week have about 30% lower mortality rates than those who eat fish twice a week compared to those who eat the least fat alone and have a high fiber content. Some people conducted a 6-week comparative trial of eating fish and cheese on 19 men and 23 women, and the results showed that the blood cholesterol of fish eaters decreased significantly, further demonstrating that eating fish meat has the effect of preventing cardiovascular disease. Nutritionists have affirmed that the diets of the people of the countries around the Mediterranean are healthy, as the inhabitants of these countries often eat fish, grains, vegetables, garlic and vegetable oils.
Recent studies have shown that deep-water fish brains are rich in brain phospholipids, lecithin and polyene fatty acids (EPA, DHA), and these nutrients are called "brain gold". It can continuously enhance the degree of brain activation, has the effect of brain nootropics to enhance intelligence, improve memory and improve IQ, and is an activated substance that delays brain aging. However, "brain gold" is difficult to synthesize on its own, and must rely on food to supplement, and there are very few in general animals and plants.
In order to live a long and healthy life, the diet of the elderly should:
(1) Eat more fish. Eat at least 2 times a week:
(2) Eat marine fish. Marine fish have a higher nutritional value than freshwater fish. For example, marine fish contain 2.5 to 10 times more iodine than freshwater fish. The seawater fish that can be eaten often are: yellow croaker, striped fish, barramun, flat-mouthed fish, tuna, etc.:
(3) Eat fish heads. When eating fish, you should also eat fish head, fish brain has high nutritional value, it contains "brain gold" ---- brain phospholipids, lecithin and polyene fatty acids (EPA, DHA). It is said that people who often eat fish heads are agile and flexible. #大有学问 #
