GETTING a moderate amount of plant substances called flavonoids through food may be linked to a lower stomach cancer risk in women - but not in men, according to a European study.
The researchers found that women with the highest intake of flavonoids were half as likely to develop the disease as women who had the smallest intake.
"A flavonoid-rich diet is based on plant-based foods such as fruits, vegetables, whole grain cereals, nuts, legumes, and their derived products (tea, chocolate, wine)," lead researcher Raul Zamora-Ros said.
"This kind of diet combined with less consumption of red and processed meat can be a good way to reduce the risk of developing stomach cancer," added Zamora-Ros from the Catalan Institute of Oncology in Spain.
The findings don't prove that flavonoids alone can ward off the disease, because other factors such as a healthier lifestyle may play a role.
The researchers turned to an ongoing research following almost 500,000 men and women in 10 European countries. All of the participants were between 35 and 70 years old, and had been part of the study for about 11 years.
During that time, there were 683 cases of stomach cancer, of which 288 occurred in women.
The researchers analyzed the participants' food diaries to see how many flavonoids they are on average. Green tea contains a large amount of flavonoids, with more than 12,511 milligrams per 100 grams of leaves. Pinto beans also contain a lot, with about 769mg per 100g of beans.
Women who got more than 580mg of flavonoids per day had a 51-percent-lower risk of developing stomach cancer than women who consumed no more than 200mg a day.
