Today, I went to make rounds. A patient told me that when he was browsing the web recently, he saw some "experts" who thought that eating onions often could reduce blood fat. Considering that his blood fat is a little high, but I don't know whether there is scientific basis for onion to reduce blood fat, so he asked me the question at the beginning of the article.
It must be said that the incidence of hyperlipidemia in China has indeed increased significantly in recent years, so many people are looking for ways to control blood lipids, including eating onions. Can eating onions really reduce blood fat? How can we control blood lipids? Today, the doctor's kind words will come to talk to you about this problem.
I met a 56-year-old uncle before, and found that his triglyceride was 3.7mmol/L during physical examination. Considering that he has a history of hypertension and diabetes and a high risk factor of cardiovascular disease, I suggest that he take oral drugs to control blood lipid.
My uncle told me that a friend around him controlled his blood fat by eating onions, so he wanted to try it himself. I talked with my uncle for a long time and told him that eating onions to reduce blood fat was a bit unreliable, but he just wouldn't listen. I don't think I can convince him, so I asked him to check his blood lipid a month later.
Unconsciously, a month passed, and my uncle came to check blood lipids as scheduled. After the test results came out, it was found that the triglyceride changed from 3.7 1mmol/L to 3.85mmol/L, and the blood lipid did not decrease, but increased repeatedly. Uncle was so surprised when he saw this paper that he couldn't believe his eyes.
The hypolipidemic effect of onion is widely spread among the people, and many people are convinced of it, but it should be noted that the hypolipidemic effect of onion is very small and almost negligible.
Previous studies have indeed found that onions contain components that lower blood lipids, such as diallyl disulfide and mercaptoamino acids. These two components can improve the activity of fibrinolytic enzyme in human body and play a certain role in preventing and treating atherosclerosis. In addition, onion also contains prostaglandin A, which can not only dilate blood vessels, but also prevent the formation of low-density lipoprotein.
However, regardless of the dosage, the effect is not reliable. Onions do contain lipid-lowering ingredients, but the content of lipid-lowering ingredients in onions is relatively small. If you want to control blood fat by eating onions, you need to eat a lot of onions, which is obviously unrealistic.
Some friends may find it strange. Since eating onions alone can't significantly reduce blood lipids, why do some people actually control blood lipids by eating onions? In fact, there are many possible reasons, such as insisting on exercise and taking drugs to control blood lipids.
? Pay attention to adjusting the diet structure:
I don't know if you have noticed a phenomenon. Although some friends are not fat and eat lightly, their blood lipids are still high. In fact, this is probably related to the unreasonable diet structure.
It is true that the diet is light, but many middle-aged and elderly friends usually eat more carbohydrates. Many people think that hyperlipidemia is related to eating more meat, but it is not.
When we eat carbohydrates, they will be metabolized into glucose in the human body, enter the blood, and then lead to an increase in blood sugar. In order to maintain normal blood sugar, the human body will secrete a lot of insulin. The mechanism of insulin lowering blood sugar is mainly to convert glucose into fat for storage and promote the utilization of glucose by human body. If you eat more carbohydrates for a long time, it will easily cause more fat accumulation in the human body, which will lead to hyperlipidemia. # Pension knowledge contest #
In order to control blood lipids, it is not enough to eat, but also to control the intake of carbohydrates, such as rice, noodles, sweet potatoes, sweet fruits and so on. We can appropriately increase the intake of vegetables and high-quality protein. Vegetables have strong satiety and low energy, and the dietary fiber contained in them can also delay the absorption of sugar and fat in gastrointestinal tract.
In addition, we should also pay attention to cooking methods, and try to choose steaming, boiling and stewing cooking methods. If cooking methods such as frying and frying are used, healthy ingredients will also become "unhealthy".
? Keep exercising:
Exercise is a good way to reduce blood fat, because exercise can increase the consumption of sugar and fat.
However, it should be noted that exercise needs long-term persistence. It is impossible to fish for three days and dry the net for two days. Generally speaking, it takes about three months to exercise to have obvious effects.
For middle-aged and elderly friends, aerobic exercise can be carried out, such as walking, brisk walking, Tai Chi, gymnastics, cycling and so on. First of all, walking is recommended here, because walking is easier to adhere to and safer exercise. The time of each exercise should be controlled at about 30 minutes, and the number of exercises per week should be no less than 5 times, so it is advisable not to feel tired the next day.
Warm-up exercise before exercise can reduce the risk of sprain during exercise. When middle-aged and elderly friends exercise, it is best to have someone to accompany them. When the weather is bad, try not to do outdoor sports, otherwise it will increase the risk of cardiovascular and cerebrovascular diseases such as cerebral infarction, cerebral hemorrhage and myocardial infarction. # Health Star Project #
? When necessary, you can also take some lipid-lowering drugs:
If you can't lower your blood lipid by improving your lifestyle or your blood lipid is high, you need to take some lipid-lowering drugs under the guidance of a doctor.
Many people think that medicine has three kinds of toxicity, so they think that you can try not to take medicine without taking medicine. There may be some truth in this view. However, it should be noted that the doctor will evaluate whether the patient has medication indications.
If you take the medicine in strict accordance with the dosage of the instructions, the adverse reactions of the medicine will be less. After all, drugs are produced to treat diseases. If its adverse reactions are great, what's the point of producing this drug?
In fact, the adverse reactions of drugs are really nothing compared with the harm caused by hyperlipidemia. # Health Science Competition #
