From then on, Uncle Li began to cook some onions for three meals a day, and even took onions as medicine, hoping to lower his blood pressure by eating onions.
In fact, this kind of story is not uncommon. It is said on the internet that all kinds of onions can reduce the three highs, which leads many elderly people to eat onions on time and in quantity every day, just like Uncle Li, hoping to reduce high blood pressure through diet therapy.
So can onions really drop three highs as the old people say?
Although onion is a common vegetable, its nutritional value is relatively high, and it is even called the vegetable queen among the people. Onion contains a lot of vitamin C, minerals and fiber, which can play an anti-cancer role. Onions have many benefits. Let me give you some examples:
Everyone should know the bactericidal effect of onion, because onion is rich in allicin, which has certain bactericidal ability and can be used to fight influenza virus and prevent colds.
Secondly, after being metabolized in vivo, allicin can be excreted through urinary tract, respiratory tract and sweat gland, and when excreted, it can stimulate the secretion of cell wall in relevant parts, thus achieving the effect of diuresis and expectoration.
When eating, many people find dishes with onions more appetizing. This is because onion contains allicin, which can emit a special smell, which can stimulate the secretion of gastric acid in the body, thus improving people's appetite.
Secondly, relevant personnel found in the research process that onions can also improve gastrointestinal tension and promote gastrointestinal peristalsis, so proper consumption of onions can play an appetizing role. At the same time, it can also relieve anorexia caused by atrophic gastritis and dyspepsia.
Onion contains a lot of quercetin and selenium, among which quercetin can inhibit the activity of cancer cells and avoid the formation of cancer cells. Selenium is an antioxidant, which can stimulate immune response and inhibit the division and growth of cancer cells, so it can reduce the risk of cancer.
Onion contains more vitamin C and nicotinic acid, which can promote the formation of interstitial cells and help damaged cells to repair themselves, thus making the skin smoother and more elastic.
In addition, onion is rich in vitamin E and sulfur, which can effectively prevent the formation of lipofuscin pigment, thus playing a role in preventing senile plaque.
So, onions have so many benefits, can they be used to reduce the three highs? Don't worry. Next, Dr. Li will give you a good talk.
The nutritional value of onions is really high. Although onion is only a vegetable, it still contains a lot of protein, carbohydrates and dietary fiber, as well as various trace elements, such as phosphorus, magnesium and potassium, which can promote health. But the reason why onions can drop three highs is inseparable from the following two substances.
Onions contain a substance called prostaglandin A, which is like a natural blood thinner. It can dilate blood vessels and reduce blood viscosity, so it can be said that it has a certain antihypertensive effect. But food is different from medicine, which has little effect on the treatment of diseases, and long-term intake of a single food is not good for the health.
In addition, onion also contains a substance called urinary butyric acid, which can promote cells in the body to make better use of sugar, thus lowering blood sugar. In addition, onion also contains diallyl sulfur, which can prevent arteriosclerosis and reduce blood lipid, so in theory, onion has the effect of reducing three highs.
But this is only theoretical and cannot be divorced from reality. Because the content of these two substances in onion is not much, it is almost unrealistic to supplement this substance by eating onion to achieve the effect of lowering blood pressure.
In addition, in the process of cooking onions, the treatment of onions may lead to insufficient dissolution of effective components; Secondly, when onion is cooked at high temperature, it may destroy its effective components, thus losing its function, resulting in the inability to ingest the effective components, further reducing the already trace substances.
Therefore, from the actual situation, simply eating onions can not play a role in treating diseases. Therefore, it is not recommended for hypertensive patients to lower their blood pressure by eating onions. It is best to follow the doctor's advice and take the medicine on time. Although onions can't be used as antihypertensive drugs, daily consumption is helpful for lowering blood pressure.
Three highs in human body mainly refer to hypertension, hyperlipidemia and hyperglycemia. No matter which one is too high, it will have a certain impact on the body. Since eating onions alone can't reduce the three highs, can we reduce the three highs through other reasonable diets?
First of all, we can supplement potassium in moderation. According to related research, supplementing enough potassium every day can effectively reduce obesity and metabolic syndrome. This is because potassium ions can effectively resist sodium ions, and carry them out of the body with urine, thus lowering blood pressure.
Therefore, you can eat more foods rich in potassium, such as celery, spinach, bananas, oranges, watermelons, and some mushrooms rich in potassium, such as Hericium erinaceus and Pleurotus ostreatus. Those with severe potassium deficiency can also take potassium supplements directly under the guidance of doctors, such as potassium chloride and potassium citrate.
Secondly, the daily dietary fiber can not be less. Dietary fiber is one of the indispensable nutrients for human body, and it is known as the seventh largest nutrient for human body. Adults need to consume at least 25g dietary fiber every day, which can not only meet the needs of the body, but also reduce metabolic syndrome.
For ordinary people, if you want to increase the intake of dietary fiber, you can achieve it through daily diet. For example, fresh vegetables, fruits, beans and wheat bran are rich in dietary fiber. Eating about 500 grams of vegetables or 200 grams of fruits every day and appropriately increasing the intake of coarse grains and whole grains can meet the human body's demand for dietary fiber.
Furthermore, omega-3 fatty acids should be supplemented appropriately. Omega-3 fatty acid is a substance that can effectively reduce the cholesterol content and blood pressure in human body, and this substance is mainly concentrated in deep-sea fish and edible oil, such as common sardines, linseed oil and walnut oil, which all contain more omega-3 fatty acids. You can eat more of these foods to supplement them, and you can also have a certain therapeutic effect.
In addition to the above-mentioned foods that need to be supplemented in moderation, these two foods should also be avoided as much as possible.
Try not to eat high-sugar food. The human body's calories mainly come from sugar, but long-term intake of high-sugar foods can easily lead to the emergence of metabolic syndrome, leading to an increase in the risk of diabetes and hyperglycemia. Therefore, in daily life, we should pay attention to stay away from high-sugar foods, and the daily intake of sugar should not exceed 25 grams, especially artificially added sugar.
Patients with "three highs" should try to eat less carbohydrates. Excessive carbohydrate intake will lead to obesity, and obese people will be accompanied by different degrees of insulin resistance. Moreover, carbohydrates contain less dietary fiber, but are high in calories, so we should pay attention to reducing carbohydrate intake in daily life.
Patients with "three highs" should also eat less sodium. According to research, if the body ingests more sodium, it will be more prone to insulin resistance and metabolic syndrome. In addition to the salt added when cooking, chicken essence, monosodium glutamate, sauce and bacon all contain sodium, so try to eat as little as possible.
For patients with hypertension, hyperglycemia and hyperlipidemia, it is recommended to go to the hospital in time. With the help of doctors, use related drugs for reasonable treatment and control. Because whether it is hypertension, hyperlipidemia or hyperglycemia, it will cause certain damage to the organs of the body, which will lead to various diseases in the long run.
For hypertension, antihypertensive drugs can be used to lower blood pressure under the guidance of a doctor.
There are five common antihypertensive drugs. The first kind of diuretics are hydrochlorothiazide and so on. The second kind of calcium antagonists are widely used antihypertensive drugs in clinic, such as nifedipine and amlodipine. The third type of angiotensin converting enzyme inhibitors, such as fosinopril and benazepril, can protect renal function and improve myocardial hypertrophy while lowering blood pressure. The fourth category is angiotensin ⅱ receptor antagonists, such as valsartan, olmesartan, irbesartan, telmisartan, candesartan, etc., which can also protect renal function and improve myocardial hypertrophy. The fifth category is beta blockers, such as metoprolol tartrate and bisoprolol, which can lower blood pressure and slow down heart rate at the same time.
The above five types of antihypertensive drugs are taken in no particular order. According to the different conditions of patients with hypertension, choose appropriate antihypertensive drugs, and choose one or even more drugs to reduce blood pressure.
For patients with hyperglycemia, if they have developed diabetes, they need to be treated with hypoglycemic drugs, such as metformin, sitagliptin and insulin injection. For patients with hyperlipidemia, drugs for lowering blood lipid can be used, such as statins, rosuvastatin, atorvastatin, etc.
However, due to individual differences, there are individual differences in the response of each patient to drugs, as well as the condition and complications of different patients, so there are huge differences in medication. Every patient needs to go to the hospital, after the evaluation of professional doctors, choose the right medicine for scientific treatment.
Although onions have high nutritional value, they taste very delicious when cooked. However, onion can only be used as a diet therapy, which can help reduce the three highs, and cannot be used as a drug to treat the three highs.
Moreover, the normal life of the human body needs all kinds of nutrition. Eating onions for a long time may lead to an imbalance in nutrient intake in the body, which in turn leads to an imbalance in nutrients in the body and also leads to various diseases. Therefore, in the daily diet, food should be diversified, balanced in thickness, and mixed with meat and vegetables, so as to make the nutritional intake more balanced and promote health.
In addition, for patients with three high, we should pay attention to the use of antihypertensive drugs, lipid-lowering drugs and hypoglycemic drugs in strict accordance with the doctor's advice. At the same time, we should also pay attention to adjusting our lifestyle, focusing on a low-salt low-fat low-sugar diet, and secondly, we should pay attention to quitting bad habits such as alcohol and tobacco.
In addition, we should pay attention to proper physical exercise. Long-term regular exercise can improve physical fitness and immunity, prevent diseases and effectively reduce the occurrence of diseases. Moreover, for some three-high diseases, proper exercise can help patients better control the levels of hyperlipidemia, hyperglycemia and hypertension in the body.
