Absolutely right! ....Beer is mostly water.
Even the Coneheads knew to drink mass quantities to prevent kidney stones.
My friend who got k-stones drank few beers but bought Jack Daniels by the case.
Been drinking beer over 60 years and have had no medical issues or Rx. Still have all organs I had when born.
Beer does indeed flush them. Let me drink too much beer and I would be passing a kidney stone the next day along with the hangover. While it made for a horrid day, I would be grateful that I was passing it instead of later when it was even bigger; although the dehydration generally made it take three days as opposed to one. Ha! It felt like just desserts for over-imbibing.
Everyone is different. I’ve read that tart cherry juice is supposed to be the best for gout, but it does nothing for me. I’ve also tried apple cider vinegar and lemon and some other things that I can’t remember at the moment. The only thing that works beautifully for me is pineapple juice. I pray that it never stops working as it is wonderful to not have to deal with stones or gout any longer. I dread the thought of its return.
