Alcohol consumption can damage the DNA of even young drinkers who only drink on the weekends.
A new study from two universities in Mexico found students who drank only on weekends, and who were otherwise healthy and showed no other signs of long-term alcohol consumption, had nearly twice the amount of oxidative damage to their DNA than students who did not drink. Researchers also found students who drank had 5.3 times as many damaged cells as students who did not.
“[T]he fact is, there should not have been any damage at all because they had not been consuming alcohol for very long, they had not been exposed in a chronic way,” lead researcher Adela Rendón was quoted as saying. “This is social alcohol abuse, but which causes damage in the long term and you have to be aware of that.”
