IT's official. Guinness is indeed good for you, the famous advertising slogan confirmed by recent research findings at the University of Wisconsin Medical School. Apparently researchers found that dark stouts have abundant nutrients called flavonoids, compounds stripped out from lagers and beers by differences in the brewing process. These compounds are seen as beneficial to blood circulation, soaking up "free radicals ", like cholesterol and acting as a deterrent against clotting. So now you know Naturally Guinness is pleased but is unlikely to extol the health factor in future advertising. The "Guinness is good for you campaign, which carved out a niche in the annals of contemporary advertising, started in unregulated 1928 when newspapers were full of claims for all sorts of pills and potions. In later years advertising standards prohibited Guinness from using health claims to promote the brew. So cheers and good health.!
