Three reasons of onion antithrombotic.
First, onions are rich in flavonoids.
Flavonoids can effectively prevent platelet aggregation. It is important to know that thrombosis occurs in human blood. A large part of the reason is that a large number of platelets in the blood coagulate together, thus blocking blood vessels and eventually forming thrombosis. Flavonoids in onion can effectively prevent platelet aggregation, thus avoiding thrombosis.
Second, onions are rich in sulfides.
This kind of sulfide mainly refers to diallyl sulfide, which can effectively prevent the occurrence of vascular sclerosis and reduce the content of blood lipids, thus avoiding the occurrence of thrombosis, which is beneficial to vascular health.
Third, onions are rich in prostaglandin A.
Prostaglandin A has a strong vasodilating effect and effectively reduces blood viscosity, so sticking to eating onions can greatly reduce the risk of hypertension. Prostaglandin A can also effectively resist catecholamine and prevent atherosclerosis, thus preventing thrombosis.
Although onions are good, four types of people are "forbidden to eat"
First, people with allergies should not eat. Onions are irritating to some extent. People with allergies are more likely to induce allergic reactions after eating. Common symptoms such as itching, redness and asthma are very dangerous.
Second, people with eye diseases should not eat it. After the onion is cut, the thiopropionaldehyde -S- oxide in it will irritate the eyes and skin, leading to the aggravation of eye diseases, which is not conducive to eye health.
Third, patients with gastric ulcer should not eat. Onions can stimulate gastric acid secretion and play an appetizing role. However, excessive gastric acid secretion in patients with gastric ulcer will aggravate the ulcer and lead to stomach pain, which is unhealthy.
Fourth, people with diarrhea, if they have diarrhea for a long time, it is best not to eat onions, because it will aggravate diarrhea.
