A potassium-deficient diet can increase systolic and diastolic blood pressure in normal men. Therefore regular consumption of foods high in potassium and low in sodium or sodium-free salt can have a synergistic effect on lowering blood pressure. For example, celery, mushroom, purple cabbage, winter melon, fungus, peanut, onion, bitter melon, water chestnut, garlic, sea cucumber, honey, lotus vegetable and apple are all high potassium and low sodium foods. In addition, seafood containing more iodine, such as kelp, seaweed and shrimp skin, have a certain improvement effect on hypertension atherosclerosis, because iodine is an important element to prevent atherosclerosis. Hypertensive patients should eat more vegetables Vegetables are beneficial to hypertensive patients, it contains a large amount of vitamin C and fruit acids, which can make the body excess cholesterol out of the body, thus effectively preventing the occurrence of atherosclerosis. Vegetables contain very little sodium and a lot of potassium. We all know that sodium plays a role in the development of hypertension, while the role of potassium is exactly the opposite of sodium, potassium plays a role in the reduction of blood pressure. Therefore, eating more vegetables can lower blood pressure by decreasing the ratio of sodium to salt and increasing the ratio of potassium to salt, and also vegetables contain very little fat and sugar, so eating more will not make people fat. At the same time, vegetables contain more fiber can promote intestinal peristalsis, so that excess fat discharge, very beneficial to weight loss. There are many varieties of vegetables, but not all of them are good for hypertensive patients, like potatoes, yams, pumpkins and other high starch and sugar should not eat more. Some of the vegetables that are recognized as good for lowering blood pressure are tomatoes, celery, kelp, Ulva, fungus, water chestnuts, broccoli, lotus, sea vegetables and cilantro. Fruits are good for hypertensive patients Fruits, like vegetables, contain a large amount of vitamins and minerals such as potassium, magnesium, iron and calcium. Fruits and vegetables are much the same and each has its own benefits. Fruits in the high content of vitamin P, can reduce the content of cholesterol in the blood, can also increase the resistance of the blood vessel wall, hypertensive cerebral hemorrhage has a certain preventive effect; vitamin E is known as an anti-aging agent, it has to strengthen the function of blood vessels and anti-coagulant effect, but also can reduce the body’s demand for oxygen, the combination of coronary heart disease and cerebral blood supply deficiency of hypertensive patients is very beneficial; magnesium can not only prevent hypertension Magnesium not only can prevent the occurrence of hypertension, but also can treat hypertension; iron is one of the necessary components of hematopoiesis; calcium plays an important role in neuromuscular. There are many fruits that have a preventive and curative effect on hypertension, such as watermelon, lemon, orange, hawthorn, persimmon, apple, kiwi, mango, grape, date and so on. High blood pressure patients should have a low salt diet High salt can make blood pressure rise, low salt can make blood pressure lower, northerners eat more salt than southerners, so the blood pressure of northerners is generally higher than southerners. However, not all people who eat a lot of salt will develop hypertension, and about 1/5 of people are sensitive to salt. When these people eat too much salt, hypertension will occur, and if they already have hypertension, it will make their blood pressure higher. The World Health Organization (WHO) recommends that salt intake should be limited to less than 5g per day because medical science cannot yet distinguish people who are sensitive to salt. However, salt restriction does not mean that the less salt you eat, the better, and excessive salt restriction has certain side effects. Acute salt restriction can cause a decrease in fluid volume and an increase in the activity of the renin-angiotensin system and sympathetic nervous system, which can lead to an increase in blood pressure in some patients. Excessive salt restriction can also cause many adverse metabolic reactions, resulting in a decrease in heart rate, fatigue, dizziness and even syncope. For hypertensive patients, salt should be limited, but for normal people do not have to be too demanding, can be relaxed to 6-10g per day. Hypertensive patients should control the fat diet Fat is the fat in plants and animals. It is one of the five major nutritional elements required by the human body. Generally speaking, patients with hypertension should control animal fats containing high cholesterol and the foods they replicate into. Because foods high in cholesterol are associated with the onset and development of atherosclerosis, it is good to eat less of them. In contrast, vegetable oils contain mainly unsaturated fatty acids, which undergo a series of changes in the human body and are absorbed and utilized, in the middle of which can make blood vessels dilate and blood pressure lower, which can prevent thrombosis and also have an anti-atherosclerotic effect. The unsaturated fatty acids in vegetable oil can reduce the activity of enzymes, so that the synthesis of fat in the body is reduced and weight is reduced, which has a hypotensive effect on obese hypertension and can increase the efficacy of antihypertensive drugs. Fat is the supply of high quality energy, which contains cholesterol is not useless, and is an important and necessary component of the human body, to maintain the normal physiological activities of the human body is a “merit”, but not in excess. Therefore, for people with mild hypertension, under 40 years of age and not fat, and with normal blood cholesterol values, it is not advisable to restrict fat intake. And animal fat also contains more unsaturated fatty acids in oils such as fish, especially sea fish, also contains “polyencon” component is a good medicine to soften blood vessels. There is a very interesting phenomenon, the more diluted fats for hypertension patients, lard is better than beef and lamb oil, chicken and duck oil is better than lard, vegetable oil is better. Fish oil, on the other hand, can be directly used in medicine and has extraordinary curative effects.
