With the improvement of living standard of the country, people gradually enter a high-calorie diet, lack of exercise, and high mental tension, resulting in a gradual increase in the prevalence of hypertension, and a trend of youthfulness, the prevalence of hypertension in adults was 18.8% in 2002, an increase of 31% over 1991. It is estimated that there are 200 million hypertensive patients in the country, and at least 2 out of every 10 adults are hypertensive. The theme of National Hypertension Day on October 8, 2009 is: “Salt and Hypertension”. Low salt is listed in the first place to keep away from hypertension, because salt is the “secret killer” that endangers life. Most of our residents have a high salt diet. According to the 2002 China Population Nutrition and Health Survey, the average daily salt intake of urban and rural residents in China is 12 grams per person, including 12.4 grams in rural areas and 10.9 grams in cities: the northern areas are higher than the southern areas. High salt diet is an important risk factor for hypertension. The prevalence of hypertension tends to be higher in populations in areas with high salt diets. According to statistics, the north of China, especially in the northeast, due to the cold climate and less vegetables and fruits, the average person eats 12-18 grams of salt per day, while in the south it is lower, thus causing the incidence of hypertension in men in the northeast than in the south, such as the Shanghai area, to be about one times higher. Salt can not only make a lot of people hypertension, but also directly damage the walls of blood vessels throughout the body, causing vascular sclerosis, leading to myocardial infarction or kidney function decline. How can we achieve a low-salt diet? 1, strict salt restriction. The daily salt intake standard (4-6 grams) set by the World Health Organization. Japanese from the end of the Second World War in the early days (1950s) to the end of the 20th century, with the improvement of living conditions, people have been from eating dried salted fish to eat a lot of fresh vegetables and fruits, the average salt intake from 29 grams per person per day to less than 10 grams, the Japanese hypertension incidence rate has declined year by year a major reason, followed by a significant reduction in stroke patients, from which we can We can learn from this. Change your eating habits, do not eat or eat less salted vegetables, salted fish and all kinds of salt-pickled food, and develop a “light” diet. Remember the salt content of the following salty dishes: a single piece of 4 cm square curd contains about 5 grams of salt, a small dish of pickled vegetables (such as squash) contains 4 grams of salt. In addition, many people in our country usually have the habit of putting MSG when cooking vegetables or soup, and 1 gram of MSG contains 0.5 grams of salt. Many vegetables such as cabbage, bean sprouts, shrimp, purple cabbage contain a certain amount of sodium salt. 2, eat more food rich in potassium and calcium. Through in-depth research, we know that potassium and calcium have an antagonistic effect on sodium, and supplementing potassium and calcium can promote sodium excretion. It is recommended to eat more calcium-rich vegetables and foods, such as spinach, rape, potatoes, sweet potatoes, mushrooms, fungus, milk, soy products, etc. 3, it is recommended to take red lentils, mung beans, watermelon, winter melon, cucumber, white radish and other foods with diuretic sodium excretion effect. Recommend two diuretic tea drink formula: (1) 10g corn husk, 1 tbsp honey, 3g green tea, decoction for tea, 1~2 times a day. (2) 3g of bamboo leaves, 6g of white foxglove, decoction of water to drink as tea, 1~2 times a day. Job’s tear and red beans have the effect of profit and swelling, commonly used to cook porridge can help the body to excrete excess water and salt. In conclusion, reducing salt intake in normal people can prevent the occurrence of hypertension, reduce the morbidity and mortality of stroke, heart disease and chronic kidney disease. Reducing salt intake in patients with hypertension improves the effectiveness of hypertension treatment and reduces cardiac, cerebral and renal complications caused by hypertension. Salt restriction is a very economical and cost-effective measure to prevent cardiovascular disease.
