Men eating fish once a week can protect their heart

　　According to a recent study in the United States, male Eating deep-sea fish once a week, or a moderate dose of omega-3 fatty acids, can help reduce the risk of heart failure.

　　From 1998 to 2004, researchers in the United States and Sweden followed 40,000 Swedish men aged 45 to 79, recording their dietary details and healthy situation. It was found that men who ate fish rich in unsaturated fatty acids (such as salmon, mackerel, herring, whitefish) once a week had a 12% lower incidence of heart failure than men who never ate fish. Meanwhile, men who consumed about 0.3 grams of omega-3 fatty acids (found in cod liver oil and fish oil) per day had lower rates of heart failure than those who consumed less.

　　However, if you consume too much fish every day or consume a larger dose of omega-3 fatty acids, you will not be able to protect your heart. You may even have the same risk of heart failure as those men who never eat fish and omega-3 fatty acids.

　　“The results may lead to lifestyle changes. ”Dr. Emily Levitan, a cardiologist at Harvard Medical School and leader of the study, said: "However, this result may have another explanation. People with poor physical fitness may be more inclined to eat too much fish or fatty acids to enhance nutrition, so the occurrence of heart failure in these people may be related to their physical fitness. ”(Geng Xiaowei)
