Drinking 8 glasse of water a day...is it mega important?

" Caffeine may act as an irritant for those who have kidney stones because of its diuretic effects and it may also contribute to their formation because of the oxalate in coffee"




I love it when studies are quoted and they use the word "MAY" in the findings..............so conclusive. The sky MAY be falling too

if you don't drink enough water you retain water weight and don't digest properly. It's reccomended you get half your body weight in water.

Recommended by whom? So a 200 lb person should drink 100 lbs of water? Isn't that about 12 gallons of water?

Um, no. Your kidneys filter your blood. They don't filter out the other things you drink, that's called "digestion" and it happens in your stomach and small intestine. Kidney issues are exacerbated by dehydration, not by drinking any one specific liquid. As for the diuretic comment, water has much stronger diuretic properties than the caffeine in coffee can ever hope to have.

UM yes! Your kidneys filter your blood...got it ! But what is in your blood stream if digestion solved the problem of filtering everything else than why do we even have kidneys?? Because there is waste in your blood...this is waste created by the normal breakdown of active tissues, such as muscles, and from food - what you are eating is what goes into your blood stream ie water, caffine, protein, sodium etc.....digestion breaksdown the dense parts of food, and the microscopic particales that are in what you eat goes through the membrains of your stomach and intestines into your blood stream. So "you are what you eat"

During the filtering process the "waste" is eliminated from the body through urination. When you drink something with caffine your kidneys have to filter this out of your blood....because your kidneys are working hard you may have to urinate more frequently which can cause dehydration.

The kidneys filter out waste sent from other organs. They don't just filter random things like caffeine out of your blood. They filter the blood, then reabsorb what they filter, sending them on their way to various organs and cells for processing. Then the organs and cells send their waste products to the kidneys for excretion. c it's absorbed and sent to the brain, where the brain uses it to reduce the effects of adenosine, which is why you feel more awake.

Diuretic Effects of Coffee
Coffee is one of the most popular brewed beverages in the U.S. and around the world. One of the primary causes of its popularity is due to its high caffeine content. According to MayoClinic.com, an average 8 oz. cup of caffeinated brewed coffee has from 95 to 200 mg of caffeine. This amount compares to 40 to 120 mg for black tea and approximately 30 to 50 mg for caffeinated soft drinks. In addition to its stimulant effects, caffeine is a known diuretic. A diuretic acts upon the kidneys by increasing the removal of water from the bloodstream, resulting in increased urine output.
Kidney Stones and Coffee
Kidney stones form by precipitation of solid masses out of your urine. According to the NKUDIC, the most common form of kidney stone is calcium oxalate. Caffeine may act as an irritant for those who have kidney stones because of its diuretic effects and it may also contribute to their formation because of the oxalate in coffee. The NKUDIC suggests that you limit your coffee intake to one or two cups per day to limit its effects on kidney stones.

"...nor does it cause significant dehydration or electrolyte imbalance during exercise."


http://europepmc.org/abstract/MED/12187618 the diuretic effect of caffeine is minimal

"The literature indicates that caffeine consumption stimulates a mild diuresis similar to water, but there is no evidence of a fluid-electrolyte imbalance that is detrimental to exercise performance or health"

"Investigations comparing caffeine (100-680 mg) to water or placebo seldom found a statistical difference in urine volume."

" Caffeine may act as an irritant for those who have kidney stones because of its diuretic effects and it may also contribute to their formation because of the oxalate in coffee"




I love it when studies are quoted and they use the word "MAY" in the findings..............so conclusive. The sky MAY be falling too

Since one study is rarely proof of anything, "may" is fairly standard language for study conclusions.

It's very common. It's filler when they don't really know but are still trying to sell their idea. It's like saying "saved or created jobs" lol

If you're pee is colorless you're good.

No, it's because it is a conclusion or theory based on suggestive but not conclusive evidence.

coffee will dehydrate you and make you retain water so be careful!
