Intervention Ups Fruit, Vegetable Intake for Women with Breast Cancer
(HealthDay News) — A nutrition education intervention can increase fruit and vegetable intake among women with breast cancer, according to a study published in the January-February issue of the Journal of Nutrition Education and Behavior.
Cecilia C. Schiavon, from the Federal University of Santa Catarina in Florianópolis, Brazil, and colleagues conducted a nonrandomized clinical trial in 2010–2011 involving women from Brazil with breast cancer. Participants were divided into an intervention group (18 women) and a comparison group (75 women). The intervention included telephone and printed materials designed to convey to participants that they should increase fruit and vegetable intake and reduce red and processed meat intake.
In the intervention group vs. the comparison group, the researchers identified an increase in fruit and vegetable intake and reduction in red and processed meat intake; there was no change in body weight, and an increase was observed in glutathione. Only the consumption of fruits and vegetables was significantly higher in the intervention group, after Bonferroni adjustment.
"This study presents improved dietary changes after a theory-driven nutrition education intervention," the authors write. "Although the sample size is small, it has proven to be clinically relevant."
