...WHEL study, led by researchers at the University of California, San Diego, was designed to be more rigorous than previous research. It tracked 3,088 women aged 18 to 70, who had been treated for early stage breast cancer. The women were divided into two groups. The first group was asked to eat five servings a day of fruits and vegetables, a diet the National Cancer Institute recommends for everyone. The other group of women received intensive nutritional counseling - including cooking classes - to help them decrease their fat intake to 15% a day and increase their regular fiber intake...
...Researchers tracked the women's diets between 1995 and 2000, and followed cases of breast cancer recurrence until 2006. By the end of the study, both groups of women had about the same number of breast cancer relapses and deaths. There were 518 relapses, with 256 in the "five-servings-a-day" group and 262 in the intervention group...
...deaths reported, more than 80% were due to cancer. Among those deaths, 160 were in the "five-a-day" group and 155 were in the high-fruits-and-veggies group. "The main conclusion is that a woman who has been diagnosed with breast cancer doesn't need to go to extraordinary lengths to eat fruit and vegetables," says Dr. Cheryl Rock, a co-investigator of the study and professor of nutrition at the University of California, San Diego. "But this study doesn't negate what we've been recommending, which is five servings...
...recent studies suggest, however, that certain foods may increase the risk of cancer. Publishing in the July issue of Cancer Epidemiology, Biomarkers & Prevention, researchers analyzed data from the Shanghai Breast Cancer Study and found that postmenopausal Asian women who had adopted more Western-style diets - high in red meat, bread, desserts and candy - had a two times greater risk of breast cancer than peers who stuck with traditional Asian diets consisting of vegetables, soy and fish. A separate study of 50,000 postmenopausal women, published in the current British Journal of Cancer, found that women who ate a quarter...
...diet is only one component of breast cancer prevention, and in their JAMA editorial, Gapstur and Khan call for further studies into the influence of a woman's overall physical lifestyle. "If you look at current literature on the subject, it suggests that overall energy balance - not just diet - plays a role in cancer recurrence," Gapstur says. And researchers at the University of California, San Diego, who ran the WHEL Study, are already planning to study how exercise and weight loss impact cancer prevention, according to co-author Rock...
