How do onions help treat high blood pressure?

There are more and more people suffering from hypertension. Many hypertensive patients do not pay attention to their daily lives, which leads to many accidents. Hypertension is a very dangerous disease. We must pay special attention to it in life and not be too tired. Diet can also be very helpful for hypertension. Some people don’t know that onions actually have an inhibitory effect on the treatment of hypertension. Let’s learn about how onions can help treat hypertension.

1. Maintain cardiovascular health

Scientific research has shown that onion is the only vegetable we eat that contains prostaglandin A, a substance that can dilate blood vessels and reduce blood viscosity, thereby lowering blood pressure, increasing the ability to dilate blood vessels, reduce blood viscosity, and prevent thrombosis. Onions are rich in quercetin, which has a high bioavailability. Scientists' research reports indicate that quercetin may help prevent the oxidation of low-density lipoprotein (LDL) and provide important protection against atherosclerosis.

2. Prevent cancer

In this society where people are afraid of cancer, it is great news that there is a food that can prevent cancer! What's more, researchers have found that onions and their family members can help prevent and control various cancers. It's "all kinds"! A study conducted on women in France showed that those who consumed more onions and garlic had a lower risk of breast cancer.

The anti-cancer effect of onions comes from the two nutrients it contains: selenium and quercetin. Selenium is an antioxidant that can enhance the body's immune response speed, thereby inhibiting the division and growth of cancer cells, while also reducing the toxicity of carcinogens. Quercetin can inhibit the activity of cancer cells and prevent the growth of cancer cells. A survey shows that people who eat onions regularly are 25% less likely to develop stomach cancer and 30% less likely to die from stomach cancer than those who do not eat onions.

3. Stimulate appetite and help digestion

Onions contain allicin, which has a strong aroma. When processed, the pungent smell often makes people cry. It is this special smell that stimulates gastric acid secretion and increases appetite. Animal experiments have also shown that onions can increase gastrointestinal tension and promote gastrointestinal motility, thereby playing an appetizing role. It has a significant effect on loss of appetite caused by atrophic gastritis, insufficient gastric motility, indigestion, etc. Of course, if you are dieting to lose weight, then this effect of onion is obviously not suitable for you!

4. Sterilization and cold prevention

Onions contain phytoncide such as allicin, which has strong bactericidal ability and can effectively resist influenza virus and prevent colds. When this phytoncide is excreted through the respiratory tract, urinary tract, and sweat glands, it can stimulate the secretion of the cell duct walls in these locations, so it also has the effects of expectorant, diuretic, sweating, and antibacterial and preservative.

Through the above introduction, everyone should have a basic understanding of the common sense of onions in treating hypertension. It can be seen that onions have high edible value and are helpful for many diseases in life. However, there are also many diseases that are not conducive to eating onions. Patients should understand their own physical condition. I hope the above content will be of great help to everyone.
