Fish is an aquatic food that people like to eat. It is not only nutritious, contains a lot of high-quality protein, but also has less fat. The taste is delicate, smooth and easy to digest. In recent years, it has been found that women are more suitable to eat more fish. In addition to low fat and high calories, eating fish often is not easy to gain weight. Eating fish has the following special benefits for women. Eating fish during pregnancy is beneficial to the healthy growth of the fetus. Danish scientists investigated the diet of 8,000 pregnant women and how often they ate fish during pregnancy. The results show that pregnant women who often eat fish are much less likely to give birth to premature and low birth weight babies than those who don't eat fish or seldom eat fish. They also found that the rate of eating fish once a week during pregnancy was only 1.9%, while that of pregnant women who never ate fish was 7. 1%. Researchers believe that fish is rich in omega-3 fatty acids, which may prevent premature delivery and effectively increase the birth weight of newborns. Pregnant women often eat fish to reduce the occurrence of depression. American doctors have found that the more omega-3 you take from marine fish in the third month of pregnancy (which means eating fish 2-3 times a week), the less likely you are to suffer from depression during pregnancy and postpartum. Scientists explained that omega-3 fatty acids are the key "building materials" of the brain. If there is no omega-3 in food, the chemical called serotonin in the brain will decrease, which will cause or aggravate depression. Experts advise pregnant women to eat more salmon, sardines and herring rich in omega-3, but not sharks, swordfish and mackerel with high mercury content. Women can prevent breast cancer by eating fish. Studies have shown that the incidence of breast cancer among Icelandic women in Japan, South Korea and Northern Europe is low, which is related to their frequent consumption of deep-sea marine species. Finnish researchers have found that essential amino acids and omega-3 fatty acids contained in fish can inhibit the formation of cancer cells and prevent them from multiplying. If you eat fish twice a week, you can reduce the recurrence rate of breast cancer. Studies have shown that fish oil has a good effect on breast cancer and lymphoma. To prevent cancer, sardines, herring, yellow croaker and so on can often be selected, and the ink of cuttlefish also contains unique anticancer substances. Eating fish for diabetic women can prevent complications. Women with diabetes have a particularly high risk of cardiovascular disease. However, foreign studies have proved that the more diabetic women eat fish, the less likely they are to suffer from heart disease in 16 years. The study also found that diabetics who eat fish more than five times a week have the least risk of heart disease. Compared with patients who seldom eat fish, the incidence of heart disease in the former can be reduced by 64%. Experts believe that it is very reasonable and effective to eat fish at least twice a week for both diabetic and non-diabetic patients. Women who eat more fish can prevent strokes and cardiovascular diseases. British researchers tracked 80,000 women aged 34-35. 14 years later, it was found that eating fish often can reduce the risk of stroke in women. If you eat fish five times a week, the incidence of stroke in women can be reduced by 52%. The reason is that unsaturated fatty acids contained in fish can offset saturated fatty acids and reduce blood lipids, especially triglycerides and low-density lipoprotein cholesterol (bad cholesterol). This fatty acid can also prevent platelet aggregation, thus preventing thrombosis, cardiovascular disease and stroke. Eating fish for girls can relieve dysmenorrhea. Some experts believe that dysmenorrhea is a phenomenon caused by prostaglandin secretion, and girls suffering from this disease are not alone. Danish experts found that girls with a history of dysmenorrhea were given two grams of fish oil every day, and after three months, their dysmenorrhea symptoms improved. Experts believe that omega-3 fatty acids rich in fish oil (including fish) can relieve dysmenorrhea. The way for girls with dysmenorrhea to eat more of this fatty acid is to eat fish often, preferably deep-sea salmon and tuna. Note: people with liver cirrhosis, tuberculosis, gout and hemorrhagic diseases (including blood diseases) should not eat fish. In addition, pregnant women who are allergic to fish should also be careful to eat fish. Pregnant women had better not take fish oil, otherwise it will increase the chance of bleeding.
