My best friend was plagued by allergies for years. He found that certain brands of beer made them much worse. It turns out that beers contain histamines of various types and levels. I don't know what brand he settled on as giving him the least trouble, Corona maybe. But he also eventually grew out of the allergies. Next time I'll ask him what the deal is on the beer.
