Teenage girls who eat more colourful fruits and vegetables are less likely to develop benign breast disease as young adults, according to a new study.
Benign breast disease, or a group of lumps that can develop during adolescence or young adulthood, is not in itself dangerous.
But benign breast disease does increase the risk of breast cancer later in life, the authors of the new study write.
Seeing the same association between certain antioxidants and benign breast disease among teen girls as has been seen for breast cancer among adults is exciting, Caroline E. Boeke said. She worked on the study at Brigham and Women’s Hospital in Boston.”Consumption of these vegetables might be a way to prevent benign breast disease,” Boeke said.
However, she noted that this is an observational study, and can’t prove veggies ward off the disease.
‘Connecting the dots’
So-called carotenoids give red, yellow and orange fruits and vegetables their colour. Some previous studies have found that women who eat a lot of them have a lower risk of breast cancer.
This study sought to “connect the dots” between eating colourful veggies as a teenager, when breast tissue is still developing, and having benign breast disease a decade later, which itself increases the risk for breast cancer in middle age, Boeke said.
Women who have benign breast disease are between one and a half and two times more likely to develop breast cancer than women without it, she told Reuters Health.
For the study, 6 500 girls filled out dietary questionnaires once a year for three years, starting when they were about 12 years old. Between nine and 14 years later, the young women filled out questionnaires about whether they had been diagnosed with benign breast disease.
The researchers divided the girls into four groups based on how many carotenoid-rich foods they ate as teens.
They found the group that ate the least amount of beta-carotene – a common type of carotenoid – was almost twice as likely to be diagnosed with benign breast disease as girls who ate the most, according to results published inPaediatrics.
“If there were a 50% reduction it would be impressive,” Cynthia Thomson told Reuters Health in an email. “But I am cautious not to over interpret these results. “In total only 122 women in the study developed benign breast disease.
