Apparently beer is on the prohibited list of foods for gout sufferers. This is because brewer's yeast is supposedly really high in purines that boost uric acid. They list purines by mg/100 gm for specific foods and you do the math to figure out many mg are in your serving. Ideal daily allowance < 400 mg. Long story short: yeast has 1810 mg/100 gm. Since there's only 11 gm dry yeast in a typical 5 gal batch this would be 0.31mg/oz or less than 4 mg/12 oz serving. Anybody know what the real deal is?
