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, writing in the American Journal of Clinical Nutrition, 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 author Raul Zamora-Ros told Reuters Health by email.
For the study, the researchers turned to 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, then they checked to see whether or not that amount was linked to the participant's cancer risk.Green tea contains a large amount of flavonoids, with more than 12,511 milligrams (mg) per 100 grams (g) of leaves. Pinto beans also contain a lot, with about 769 mg per 100 g of beans. Women who got more than 580 mg of flavonoids per day had a 51-percent-lower risk of developing stomach cancer than women who consumed no more than 200 mg a day.

Source: NEW YORK (Reuters) Just as music and lighting can influence what shoppers buy, toning down the tunes and dimming the lights in a fast food restaurant can help diners enjoy their meal more and eat less, according to a U.S. study. After transforming part of a fast food restaurant in Illinois with milder music and lighting, researchers found that customers ate 18 percent fewer calories than other people in the unmodified part of the restaurant.

Researchers from the Norwegian University of Science and Technology (NTNU), observed the relationship between perceived weights and actual weights among teenagers and young adults. "... young people who see themselves as fat often change their eating habits by skipping meals, for example. Research has shown that dropping breakfast can lead to obesity," Cuypers (researcher from NTNU) said. The first stage of the study conducted between the years 1995-1997, comprised of 1,196 normal weight male and female teens. Researchers followed up with each individual between the years of 2006-2008 where participants were between the ages of 24 and 30. Results demonstrated 22 percent of normal weight girls are more likely to classify themselves as overweight compared to nine percent of boys. Researchers believe the gender difference lies in the media advertisement that focuses primarily on targeting females rather than males. "Girls thus experience more psychosocial stress to achieve the ideal body," Cuypers said. "Society needs to move away from a focus on weight, and instead needs to emphasize healthy eating habits, such as eating regular and varied meals and eating breakfast. Good sleep habits are also an advantage. And by reducing the amount that teens are transported to and from school and recreational activities, teens might also be able to avoid getting a 'commuter belly'," Cuypers adds
