I am sorry you have gout. Glad you now have a healthier life style.
The best way to prevent future gout attacks is to lower the serum urate level to .33~.36 mmol/L (5.5~6.0 mg/dL) so that the urate crystals will dissolve and disappear from the body in months or years. Unfortunately, it is difficult to achieve this by diet, lifestyle changes, and natural/herbal medicine alone. Urate lowering drugs are generally very effective and well tolerated.
To help manage gout, you need to find out what are your serum urate level, the urine pH, and the amount of uric acid excreted in urine a day. The proper actions based on these info can prevent not only gout attacks but also bone erosion, uric acid kidney stones, and kidney failure. Sometimes, seeing a doctor and taking drugs are the best among the evils.
My additional info are:
Apple cider vinegar (ACV) & lemon juice -- I haven't seen any scientific data showing they can dissolve urate deposits, lower urate level, or prevent gout attacks. On the other hand, for people whose kidneys are deficient in excreting acids, the acids in ACV and lemon juice can accumulate in the body and is bad for gout. Occasionally, I read people saying citrus fruits, tomatoes, cranberries, and pomegranate trigger their gout attack. I wonder if it is because their kidneys can't take care of the high level of acids in these fruits.
Alcohol -- It can raise the serum urate level and trigger gout attacks. It can also raise the blood pressure. Stop drinking alone does not cause gout to disappear completely.
Gym activities -- physical exhaustion can trigger gout. Avoid prolonged heavy exercise.
Water intake -- Drinking too much water can cause extra loss of electrolytes in the urine and is bad for general health and gout. Common advice is to drink about 2~3 pints of water a day, or until the color of the urine is about clear. I think drinking 4 pints a day can be too much.
Bicarbonate of soda (baking soda) -- Do not take it until you study its side effects and have a doctor's permission to take it.
Dried apricots and raisons -- Sulfite, which is bad for gout, is often used as preservative in dried fruits.
My last gout attack -- fortunately, I have been free of gout attacks for more than 5 years without taking urate lowering drugs. I credit it in most part to bicarbonate of soda.
