Speaking of "vinegar" and "onion", most friends will mention that eating them can soften blood vessels, lower blood pressure and lower blood fat, but in fact, vinegar mixed with onions may not be so magical. In people's minds, vinegar is to soften the existence of blood vessels. Many middle-aged and elderly friends read some information that they should be jealous at every meal. After eating vinegar, they feel heartache, and they even think that vinegar plays a role in "dissolving thrombus" in blood vessels. In fact, this vinegar is really wearing a hat to soften blood vessels for no reason. After being absorbed by us, vinegar is decomposed into water and carbon dioxide. What can these two ingredients do? Vinegar can provide us with some minerals at most, but softening blood vessels needs to be studied.

How about onions? Onions are regarded as "friends of middle-aged and elderly people". Onion is really a good vegetable, but we should pay attention to its ability of lowering blood fat and blood pressure. In fact, in many modern animal experiments or in vitro experiments, onion does have the function of lowering blood pressure and blood lipid, and even can improve diabetes. This is mainly because the "sulfur compounds" in onions, that is, irritating volatile gases, make us cry when cutting onions. They are actually harmless to us, but they have many magical effects, such as inhibiting substances that prevent mice from producing insulin. It can help insulin secretion to be more stable, thus improving diabetes, and can also inhibit the increase of blood lipid in rats and mice, but even so, they are not clinical experiments, and their effects on human bodies are not necessarily significant, and the dosage requirements are different. Onions can only be said to be eaten often, which may help prevent and improve the three highs, but it cannot be used as a treatment.

Sulfur compounds in onions can also promote gastric acid secretion and promote appetite; The effect of inhibiting certain bacteria. However, sulfur-containing compounds are easy to decompose after preheating, and have no special spicy taste, and their efficacy is also discounted. Therefore, ordinary cold onions will be directly mixed with raw onions, which not only has a unique taste, but also has the effect of sulfur-containing compounds. In addition, onion also contains prostaglandin A, which is the only food containing prostaglandin A at present. Prostaglandin A can help the human body improve its resistance, and it is also an antioxidant, which helps to resist free radicals.

Onions are also rich in vitamins and minerals. Eating it often can help us to supplement many beneficial ingredients. Low in fat and calories, rich in dietary fiber, suitable for patients with "three highs". But back to the theme, vinegar mixed onions may also play the role of onions themselves. The effects of lowering blood fat, blood pressure and blood sugar in our minds may not be satisfactory, so we should treat them rationally.
