Whole wheat may prevent breast cancer in offspring

The daughters of rats that feast on whole wheat during pregnancy are less likely to develop breast cancer, a new study shows. Based on the findings, "it might be beneficial to include whole wheat in the diet when one is expecting," Dr. Leena Hilakivi-Clarke of Georgetown University in Washington, DC, the study's lead author, told Reuters Health. Hilakivi-Clarke and her colleagues have used rodents to evaluate a number of dietary factors in pregnancy on offspring's health risks, she added, for example showing that daughters of mothers fed a high-fat diet were at greater risk of breast cancer. "The model we're using should be relatively valid to make assumptions about what's going on in humans," she added. Some researchers have suggested that fiber may reduce breast cancer risk by bringing down levels of circulating estrogen, since the hormone can stimulate tumor growth, she and her colleagues note in their report. But evidence for an association between dietary fiber and breast cancer in humans has been mixed, and animal studies suggest that the type of fiber eaten may be a key factor. --Click the title of this post to read the full article from its source--
