Q. The other day someone wrote asking about kidney stones. To cut down on kidney stones, I drink several glasses of lemonade a week.

A. There is some scientific basis for your observation. Doctors often prescribe potassium citrate to disrupt kidney stone formation. Lemonade also contains citrate, and some research shows that lemonade therapy reduces the rate of kidney stone formation (Journal of Urology, April, 2007).

Three or four glasses of lemonade per week are probably not enough to do much good, however. Studies of “lemonade therapy” have used one to two quarts of unsweetened or low-sugar lemonade daily.

    Could you put a shot glass of lemon juice in Cranberry Juice??? Would this dilute the lemon juice and its effect???

    Lemons are delicious. I’m definitely gonna try this technique.

    I was told about 4 years ago that I had stones in both kidneys and would need surgery. I asked a doctor about about an other juice and he suggested lemon juice so since then I squeeze some fresh lemon juice every morning in some water and drink it and now I have no sign of kidney stones and this is the truth. I drink it every morning when I take a pill for something else. You have to keep drinking lemon juice for some time, it won’t help just over night when you start. I have had kidney stones in the past and they aren’t fun. This really worked for me and I have no economic interest in the production or raising of lemons.

    Here’s a twist to this subject: my late sister’s “old timey” family doctor, years ago, told her never to drink tea (southeners drink iced tea with everything!) while eating ice cream because IT WOULD/could CAUSE kidney stones.
