ATLANTA (WAOK) – A new medical study concludes an obese father may mean an unhealthy life for his children, along with an increased risk of developing certain cancers. The research project, released by Duke University, is apparently the first to link a father’s lifestyle to genetic behaviors in the children. The study’s medical team looked for links between parental obesity and a part of the DNA that controls some genes. Among the findings, the DNA of children of obese parents changed in a way that could increase the risk of developing colorectal and ovarian cancers, along with others. The change was likened to “environmental trauma.” The study appears in the journal “BMC Medicine.”
