Caffeine in coffee, tea, soda, energy drinks, and foods can place a strain on your kidneys.
Because caffeine is a stimulant, it can stimulate blood flow, increasing blood pressure and stress on the kidneys.
A 2002 study in Kidney International showed that long-term caffeine consumption exacerbated chronic kidney failure in obese and diabetic rats.
Caffeine consumption has also been linked to kidney stone formation by increasing calcium excretion in urine.
It is a diuretic thus promotes urination.
I quit drinking coffee in 1974.
I quit Dr Peppers and sweet tea @3 years ago.
I quit gatorade @5 years ago when I learned that if you are not doing strenuous exercising (really working all your muscles) it hurts more than helps.
I haven't missed them a bit and can tell they weren't good for me just tasted good
Water and diet is what I use to avoid the cramps.
