Some of my family has gout, so we're quite familiar with medications and alternatives. So when my father with pulmonary fibrosis was given a prescription for a "gout medicine", we were all confused - did Daddy get gout older than other family members? After asking a few of his hospice nurses, one finally knew the actual reason: Protein breaking down produces purines, and lung tissues break down more quickly with advanced pulmonary fibrosis, therefore producing more purines. AND since purines aggravate pulmonary fibrosis, it becomes a snowball/avalanche, so they've found that using gout medications helps slow the avalanche of purines.
Back to gout and alternative treatments. Although vinegar is an acid, it actually alkalizes the body. So when gout sufferers alkalize their body, their blood can hold more uric acid in the blood (as a liquid), so the uric acid crystals in their joints and organs (lungs in Daddy's case) disolve into their blood better. If they're able to clear this liquid uric acid via their kidneys, yay keep drinking vinegar. But not all gout sufferers can clear uric acid as efficiently as others - even if disolved in their blood.
Supposedly anthocyanins helps to clear disolved uric acid from the body. Anthocyanins come from darkly colored foods like blackberries, blueberries, sour cherries, black eggplant skins, turtle bean broth (not the beans, just the liquid after cooking).
So I'm guessing that using both vinegar and dark foods together might help my brother who has gout, but also my father who now has uric acid issues from his pulmonary fibrosis. I'm thinking a drink with mashed blackberries or blueberries in water, with a little apple cider vinegar, and a bit of stevia as needed would make a tasty, medicinal drink.
Thank you for listing other nutraceuticals and supplements - I went through your page and found most on Amazon, so I can send Daddy a package thru them - He loves natural cures (he lives very remotely, so Amazon is nice, since we can't take a plane or bus to visit him, and I'd like to send him the supplements/nutraceuticals before I can arrange to make the trip with our older vehicle).
