According to recent research conducted at the University of Iceland, milk intake during teenage years could have a negative effect on people later in life.
Researchers are now questioning whether milk has a detrimental effect on teenagers around the time of puberty because the maturing prostate gland could have heightened vulnerability.
"We believe that our data are indeed solid and provide important evidence for the role of adolescence as a 'sensitive period' for prostate cancer development," Johanna Torfadottir, a nutrition scientist, told Reuters Health. "However, we remain cautious in our interpretation. Causal inferences are not made on one study alone, thus more studies are needed to confirm our findings and also to explore possible mechanism behind this association."
Torfadottir added that while she and her colleagues found that frequent teenage milk drinkers have about a three times greater risk than moderate teenage milk drinkers of being diagnosed with advanced-stage prostate cancer later in life, previous studies revealed conflicting conclusions, with one resulting in increased milk intake protecting against the disease and the other showing no link at all.
With more than 240,890 men expected to be diagnosed with prostate cancer in 2011 and more than 33,000 expected to die from the disease, according to the National Cancer Institute, Americans should explore their options with life insurance in order to prepare for possible future healthcare issues.
