Lemonade could prevent kidney stones

In 2006 American Urological Association annual meeting in Atlanta, two research groups reported that drinking lemonade could help prevent kidney stones.
Kidney stones is one of the most painful of the urologic disorders. According to the U.S. National Institutes of Health, 1 person in 10 develops kidney stones during their lifetime and renal stone disease accounts for 7-10 of every 1000 hospital admissions.
Kidney stones form when there is a high level of calcium, oxalate, or uric acid in the urine; a lack of citrate in the urine; or insufficient water in the kidneys to dissolve waste products. The kidneys must maintain an adequate amount of water in the body to remove waste products. If dehydration occurs, high levels of substances that do not dissolve completely (e.g., calcium, oxalate, uric acid) may form crystals that slowly build up into kidney stones.
Urine normally contains chemicals-citrate, magnesium, pyrophosphate-that prevent the formation of crystals. Low levels of these inhibitors can contribute to the formation of kidney stones. Of these, citrate is thought to be the most important. Lemons are rich in citrate. Clinical research demonstrated that the regular consumption of the refreshing drink- or even lemon juice mixed with water increased the production of urinary citrate. That is why drinking lemonade could help prevent kidney stones.
Simple idea, easy logic. Why didn't I have this idea before ?

Hospital foods that NOT heal

Do you remember what typical hospital foods taste like in United States? I visited my mother in-law last weekend. The hospital foods she ate, looked like to me, were identical with that of 30-40 years ago. Years ago, those food may be considered as tasty and nutritious; but according to today's standard, they are lousy and bad for patients whom were already staffed with pizza, burger and trans-fat laden cookies.

What was on my mother-in-law's dinner tray in the hospital ?

White bread and margarine - white bread are not as healthy as whole grain; margarine is laden with trans fats.

Canned peaches - can't hospital bring fresh fruit? they are more nutritious. Canned fruit may contain pesticide residues.

Whole milk - which is fat filled and taken from cows injected with hormones.

Gelatin - which is low-nutrient, high-calorie, artificially colored jellied sugar water; they are for kid only, NOT for patients.

Juice - Juice from hospital are processed from concentrate rather than whole fruits.

Meat - those meat were from animals raised on antibiotics and hormones; which served with refined starches and pesticide-laced veggies.

People in US have paid so much in their health care cost; they deserve to eat some thing healthier when they are in hospitals.
