"As the temperature drops, the emergency department and cardiology department of hospitals have become the 'main battlefields' for admitting patients." A doctor from a Grade A Tertiary Hospital explained, "The Start of Winter marks the beginning of winter. As temperatures gradually decrease, the human body's metabolism slows down. Cardiovascular patients are stimulated by cold air, causing the sympathetic nerve to become abnormally excited, which enhances cardiac contractility and causes peripheral vasoconstriction, leading to an increase in systolic and diastolic blood pressure. Under these conditions of blood pressure fluctuation, it is easy to lead to dangerous conditions such as cerebral hemorrhage, cerebral infarction, and myocardial infarction. If there are elderly people and chronically ill individuals in the family, special attention should be paid."
However, many people believe that since heating has come early this year, health can be ensured simply by adding more clothes. This view has been refuted by health experts: in our country, 600,000 people die from coronary heart disease each year, and 1.2 million die from cerebral infarction and cerebral hemorrhage, 80% of which are caused by thrombosis in blood vessels. A large number of clinical medical experiments have proven that "it takes more than one cold day to freeze a three-foot-thick ice sheet." Cardiovascular patients often have an "invisible thrombus" pathological process before the onset of the disease. This process will not stop just by wearing more clothes or sitting in a heated room. If it continues to worsen, it will form a real thrombus. Therefore, it is advisable to carry out dietary therapy and health care to curb the progression of "invisible thrombus."
"For preventive dietary therapy for cardiovascular patients, natto is the first choice." Professor Yang Xiaoguang, a researcher at the National Institute of Nutrition and Food Safety of the Chinese Center for Disease Control and Prevention, Vice Chairman of the Chinese Nutrition Society, and Vice Chairman of the National Food and Nutrition Advisory Committee, introduced that every 100 grams of natto contains hundreds of billions of natto bacteria, which can effectively inhibit the growth of harmful bacteria in the intestines, promote the reproduction of probiotics such as Bifidobacterium and Lactobacillus, and regulate gastrointestinal function, moisturizing the intestines to relieve constipation. Most importantly, during the fermentation process, natto produces a fibrinolytic enzyme with strong activity—nattokinase. Nattokinase is a protease produced by natto bacteria, which can significantly dissolve thrombosis in the body and has been repeatedly verified by domestic and foreign scientific research institutions. It has a significant effect on the active prevention of myocardial infarction, cerebral infarction, stroke, and other diseases, and is very beneficial for improving symptoms in patients with these conditions. Compared with common thrombolytic drugs, nattokinase is characterized by high efficiency, safety, durability, and activity.
The market is full of various natto foods. Experts point out that when choosing natto, it is best to select the "national team of natto"—Yanjing Natto. As early as 2001, Yanjing Beer Group introduced advanced production equipment and technology from abroad and adopted the internationally popular green and environmentally friendly ozone sterilization system to sterilize the production workshop, conducting research and production of 1,000 tons of natto and 30 tons of natto capsules annually. Testing by research institutions such as the China National Research Institute of Food & Fermentation Industries and the Functional Testing Center of Health Foods at the College of Applied Arts and Sciences of Beijing Union University confirmed that Yanjing Natto capsules and fresh natto contain no added drugs, and their thrombolytic function and nutritional components are in no way inferior to foreign natto health foods.
Experts suggest that the earlier natto dietary therapy is used, the more effectively it can curb the development trend of invisible thrombus. After the Start of Winter, using natto to "pre-heat" the body can protect the health and safety of cardiovascular patients throughout the winter.
