Many people have the impression that cerebral infarction often favors people who like to eat large amounts of oil and meat, a vegetarian diet is also undesirable, there is also the possibility of suffering from cerebral infarction, prevention of cerebral infarction or meat and vegetables with a reasonable mix is most important. Due to the hot weather, many middle-aged and elderly people have poor appetite, and many elderly people with a sense of health care are worried about eating too many non-vegetarian dishes that cause high blood lipids and induce cardiovascular diseases, so they basically eat only vegetarian food. In fact, this understanding is not scientific, long-term vegetarianism will cause too little protein intake, so that the elasticity of blood vessels decreased, the degree of vascular sclerosis increased, the inner lining of the blood vessels easily damaged, easy to form thrombosis, but increased the risk of cerebral infarction. Middle-aged and elderly people with hypertension, hyperlipidemia, obesity and heart disease should have their blood pressure checked regularly and their blood lipids, blood sugar and blood viscosity tested. Even if the blood pressure and lipids are normal, you should not take them lightly. When the temperature rises above 32 degrees Celsius, you should take drugs to lower lipids, blood sugar and blood pressure as soon as possible under the guidance of a doctor to improve the internal blood environment. If there is headache, dizziness, syncope, hemiplegia, limb weakness and other signs of stroke, you should go to the hospital in a timely manner, and if unfortunately a brain infarction occurs, you must go to the hospital within 6 hours for treatment. In addition, we must pay attention to the balance of diet, do not be too partial to meat and vegetables, so as not to bring harm to their health.
