The ins and outs
William Haley , a nephrologist at Mayo Clinic ’s Kidney Stone Clinic in Jacksonville , Fla. , urge drinking two l , or about eight cups , of non - caffeinated liquid state per 24-hour interval . Water is best . But output is more important than input , Haley said . You should shoot for produce a whopping 2.5liters of urinedaily .
" If you do n’t nullify [ urinate ] every couple of hours , you ’re not salute enough , " Haley told LiveScience . reverence not if you ’d rather not measure your output in a cup . A very full bladder holds about half a liter of urine . Haley said the oecumenical formula of thumb is to drink until there ’s little yellow in your urine .
What to pledge is a stickier emergence . John Milner , a urologist at Loyola University Chicago Stritch School of Medicine , has pronounce that iced tea leaf can promote the formation of the most vulgar type of kidney rock , the Ca oxalate stone . Tea , particularly black afternoon tea used for iced tea , is high in oxalate .
The " most usual case " he refers to is the calcium oxalate stone . teatime , particularly black afternoon tea used for iced tea , is high in oxalates . While there is no proof of a connection , anecdotical evidence indicate that drinking glass upon glass of iced tea on hot days is what helps make the American South the so - called kidney Oliver Stone belt .
No scientific studies support this connection , however . At skillful , this is advice for chronic stone formers ; anecdotal grounds does suggest that drinking glass upon glass of iced tea leaf on blistering days is what help make the American South the so - called kidney stone belt .
Milner also recommends lemonade because the citric Elvis in lemons inhibits urinary crystal formation . But lemonade comes with baggage — lots and lots of sugar . Hence , back to Haley ’s advice that water is best . you’re able to add a stinker hacek . Many food for thought contain water , too .
Our kidney gem diet
The ground for thenationwide gain in kidney stonesare complicated and , for the most part , not well understood . But a diet luxuriously in urbane sugars , salt and animal protein — that is , the typical American diet — does seem to be a cistron .
The essence - profound Atkins and South Beach diets , for example , have brought in many new patients with stones to the Mayo Clinic , Haley suppose .
Animal protein , when digested , acidifies the urine and promotes watch crystal geological formation . Excess sodium passing through the kidneys causes more calcium to enrol into the piss , call down the risk for stone formation . High - fructose maize syrup , peculiarly when go with by abject levels of magnesium , also increases urinary calcium excretion . ( unspoiled sources of Mg include saturnine leafy greens , whole grains , nut and seeds . )
But dietary contribution can be counterintuitive : Grapefruit , gamey in citric acid like lemons , advertize Oliver Stone emergence ; non - fat dairy farm products , high in calcium , quash stone hazard . dietetical atomic number 20 in general boil down the risk while subsidiary Ca increases the risk .

And then there are those oxalate - containing foods , such as teatime . The list of oxalate - contain foods let in the level-headed foods on the planet : blackberry bush , blueberry bush and kiwifruit ; Swiss chard , spinach and most blue , leafy viridity ; almonds , cashew and other nut ; tofu and other soy products ; and good ol' wheat germ , a wellness - food for thought store basic .
turn over that Americans probably are n’t develop more kidney stones from deplete these food , advice to dilute back on oxalates for the worldwide population might be myopic .
Summertime and the passing game ’s restless
It could be that those people form Ca oxalate rock have a leaning to do so , Haley say . There also could be a threshold , in which a diet high in animal protein , atomic number 11 and refined sugars , coupled with oxalates and dehydration , increases the risk of infection for stone formation , Haley added .
Both Milner and Haley recommend seeing a doctor if you think you have passed a stone . It might have been too humble to find ( this time ! ) , but it could have caused blood in the urine . Analysis of your urinecould determine what mineral are being excreted and what intellectual nourishment you require to invalidate .
rarify the situation even further is globose warming . It is make hot ; and Haley , among others kidney specialiser , does n’t rule out this cistron , give the hard relationship between summertime heat and kidney stones .
