This is anecdotal and perhaps besides the point, but I just spent 5 days in Paris eating red meat at every meal (because I try to avoid it in the USA) and copious amounts of red wine. I drank more than a bottle one night (I'm tall and can handle it). I never once suffered the migraines and other assorted side effects I suffer in the USA when I eat red meat and drink red wine. No hangover even. Not once, and I was practically on a binge. Red food dyes injected into meat and all the preservatives in red wine in America show me how toxic our food chain is, and though they may be necessary for wine in the USA, it still shows how these chemicals can impact the human body.
