Is Guinness really 'good for you'?

Key Facts

“In Britain, they have it in the culture that drinking Guinness is good for nursing mothers,” said Karl Siebert, professor emeritus of the food science department and previous director of the brewing program at Cornell University.
According to Domhnall Marnell, the Guinness ambassador, Guinness Original (also known as Guinness Extra Stout, depending on where it was sold) debuted in 1821, and for a time, it contained live yeast, which had a high iron content, so it was given to anemic individuals or nursing mothers then, before the effects of alcohol were fully understood.
Regarding the old wives’ tale about beer’s effects on breastfeeding, Marnell added, “It’s not something that Guinness has perpetuated … and if (people are still saying it), I’d like to say once and for all, it’s not something we support or recommend.”
“In 1929, when we were about to do our first ad, we asked (ourselves), ‘What stance should we take?’ So we sent around a group of marketers (in Ireland and the UK) to ask Guinness drinkers why they chose Guinness, and nine out of 10 said their belief was that the beer was healthy for them.
