There is increasing evidence to suggest that tea, coffee, milk and oranje juice can all be helpful to gout sufferers. I will be adding some reports to GoutPal.com soon.

How do you stay hydrated?

A rough guide is 5 liters per day, which is 11 US pints or 9 UK pints (rounded up for good measure).

Don’t do it, unless you want to replace your kidneys in few years.
#1 Most of the gout suffers are overweight and have slightly higher or high blood pressure, which already put additional pressure on kidney, they (kidneys) are struggling to function normally and you adding additional load on it, plus pressure on your heart too.
5 liter a day (juice not included) it’s just insane period and more than that
could be lethal (kidney failure)

#2 It’s not the quantity but the what you drink is important. Most bottled and top water comes out in 5.7-6.4 PH level only few are little bit higher of 6.7 PH which is still slightly ACIDIC or somewhat Neutral. It’s not going to disposal nor remove any acid from the body. If you drink 1 L (40oz) Orange Juice (or Cherry Juice) a day that would help to disposal your urine acid much more than water. Also you can use PH drops (or just add Lemon Juice) or Alkaline water instead. that would help too. I’m not saying don’t drink water.
I’m saying it’s simply crazy to drink 5L a day! 2-3 liter a day (Juice included!!!) more than enough. Think about your kidney they need rest too! Exercise is good but try to exercise 24/7 nonstop and you’ll die. Orange Juice has high potassium (lowering a blood pressure) and it’s can disposal your UA.
Never overdo it. Stay healthy.
