A new study has bad news for those who eat a lot of saturated fats.
A new study finds that teens who eat high amounts of saturated fats tend to have dense breasts 15 years later, meaning that they are at a higher risk of breast cancer.
It’s not a definitive link between consumption saturated fats and a higher breast density, but it indicates that researchers may be on the right track in determining which fats play a big role in breast tissue formation, according to a University of Maryland Medical Center statement.
The findings were based on data from the Dietary Intervention Study in Children, which began in 1988 and involved more than 600 children between the ages of 8 an 10, with the majority of them being girls.
The participants often reported their diets, and researchers used MRI scans later in life to measure breast density in 177 female participants in their late 20s.
Scientists found that higher intakes of unhealthy fats and a lower intake of healthy fats were associated with denser breasts, which can place them at a higher risk of breast cancer.
Saturated fats are typically found in red meats, like beef, lmab and pork, although they are also found in poultry. They can also be found in heavy dairy products, like butter, cream, and cheese.
“Our results suggest possible long-term effects of fat intake during adolescence on young adult breast composition,” says the study’s lead author, Seungyoun Jung, DSc, a postdoctoral fellow in the Department of Epidemiology and Public Health at the University of Maryland School of Medicine, according to a statement. “This is the first comprehensive prospective analysis to examine the long-term effect of adolescent intake of subtypes of fat on breast density.”
