Social drinkers beware: Just one binge-drinking session—for men, more than three strong drinks—is dangerous even if it’s not your usual M.O. When blood samples were taken from a group of men and women with blood alcohol levels of at least .08g/dL, they showed that a binge “can cause intestinal ‘leakiness’ that allows gut bacteria to enter the liver and circulation,” which can cause fever, inflammation, and tissue damage, says the study’s Gyongyi Szabo, M.D., Ph.D. Meaning, you may be exposing yourself to some of the side effects of chronic drinking even if you’re not a chronic drinker. And where’s the fun in that? To stay healthy, make your limit two to three drinks max.
