Gastritis is an inflammatory condition of the stomach mucosal lining.
Symptoms usually include abdominal pain or indigestion, but some cases may be asymptomatic.
When the inflammation is chronic, it is usually associated with an infection by Helicobacter pylori.
This infection can also lead to peptic ulcers and gastric cancer.
Multiple studies have shown that green tea can reduce H. pylori infections and damage from that infection.
Two green tea chronic gastritis studies that show reduced risk
In a farming village in Japan, researchers did a cross-sectional study of 636 people.
The risk of chronic atrophic gastritis was 3.73 times greater for those who were infected with Helicobacter pylori.
After adjusting for this infection and all other lifestyle factors, researchers found that people who drank more than 10 cups of green tea daily had 37% reduced risk of gastritis (Shibata, Green tea consumption and chronic atrophic gastritis: a cross-sectional study in a green tea production village, Journal of Epidemiology, September 2000).
Another study examined 295 men and 443 women in a Japanese village.
They found that H. pylori infection increased the risk of gastritis almost five times, and that green tea reduced the risk of gastritis, especially among infected individuals (Iwahashi, Effects of cytotoxin-associated gene a (CagA) antibodies with Helicobacter pylori infection and lifestyle on chronic atrophic gastritis, Nippon Koshu Eisei Zasshi, November 2002).
Infection with Helicobacter pylori affects about half the world’s population.
