To Guinness lovers, this might be a welcome nugget of advice. One thing we do know is that the idea has roots deep in history, long before Guinness came along."Something I find very interesting is that we have this same old-wives tale everywhere."[In the early 1900s, the marketing campaign around Guinness, in particular, gave it a special identity as a "healthful" beverage.Because the beer initially was manufactured with a kind of yeast that gave it a high iron content, it was ."
