A new government study conducted by researchers at UC Davis and around the country, shows there's no advantage to extra servings of fruits and vegetables compared to the recommended five a day.

Ellen Gold, who head’s the UC Davis Department of Public Health Sciences, says the results were unexpected.

"We were a little bit surprised but we think that this is in a way good news for women, that if they maintain a healthy diet and have regular physical activity that they don’t really need to do anything additional beyond that in terms of their diet." 

The seven-year-study included more than three-thousand breast cancer survivors. Earlier research on whether a healthy diet prevents breast cancer has shown mixed results.
