[Internet rumors]Can eating onions and drinking green tea cure HP?Difficulty is a bit high

gossip:

Onion is a vegetable with a strong pungent smell, which makes people “cry while cutting”. I don’t know if it is for this reason, but like garlic, it has been labeled as “frequently eaten to kill bacteria”, especially its effect on Helicobacter pylori (HP).

Interpretation of the truth:

Onion is a vegetable with a strong pungent smell, which makes people “cry while cutting”. I don’t know if it is for this reason, but like garlic, it has been labeled as “frequently eaten to kill bacteria”, especially its effect on Helicobacter pylori (HP).

The bactericidal ability of onions is mainly attributed to the flavonoid quercetin contained in onions. The content of quercetin in red onion is as follows: outer skin (140 mg/100g) > middle skin content (110 mg/100 g) > core content (10 mg/100 g).[5]

There is such an experiment: 60 days after infection with Helicobacter pylori guinea pigs, orally administered 200 mg/kg quercetin per day for 15 days. The results showed that quercetin had a therapeutic effect on H. pylori-infected guinea pigs, reduced H. pylori infection in the gastric mucosa, and reduced inflammation and lipid peroxidation.[6]

However, this is still only an animal experiment, and the same effect cannot be extended to humans. At present, there is no population study on the intake of quercetin to improve the risk of Helicobacter pylori infection or canceration; Quercetin concentrations in natural foods vary. If it is calculated to a 60kg adult, 12,000mg of quercetin needs to be taken orally every day to produce the corresponding effect. Even if they eat the skin of red onions, they need to eat 8.5kg. This dosage requirement is not practical.

Therefore, we should not expect to rely on eating onions to treat HP. Similarly, although the content of quercetin in green tea is also high, the tea leaves that are brewed each time are far from the purpose of affecting Helicobacter pylori.
