As Cancer Research UK reported, lifestyle factors are linked to three out of four stomach cancers.
Evidence underscores the importance of maintaining a healthy diet.
One meta-analysis found that stomach cancer risk is 68 per cent higher in people with high salt intake compared with those with low salt intake.
A small, pilot study published of 50 people published in Cancer Prevention Research suggested that eating two and a half ounces of broccoli sprouts daily for two months may offer some protection against Helicobacter pylori (H. pylori) - the common stomach infection that causes gastritis, ulcers and even stomach cancer.
A Johns Hopkins researcher and an international team of scientists caution that eating sprouts containing sulforaphane did not cure infection by the bacterium Helicobacter pylori (H. pylori).
They do not suggest that eating this or any amount of broccoli sprouts will protect anyone from stomach cancer or cure GI diseases.
However, the study does show that eating a daily dose of broccoli sprouts reduced by more than 40 percent the level of HpSA, a highly specific measure of the presence of components of H. pylori shed into the stool of infected people.
There was no HpSA level change in control subjects who ate alfalfa sprouts. The HpSA levels returned to pretreatment levels eight weeks after people stopped eating the broccoli sprouts, suggesting that although they reduce H. pylori colonisation, they do not eradicate it.
"The highlight of the study is that we identified a food that, if eaten regularly, might potentially have an effect on the cause of a lot of gastric problems and perhaps even ultimately help prevent stomach cancer," says Jed W. Fahey, M.S., Sc.D., an author of the paper who is a nutritional biochemist in the Lewis B. and Dorothy Cullman Cancer Chemoprotection Center at the Johns Hopkins University School of Medicine.
