The results showed that the risk of drinking 3-8 ounces of coffee every day people suffering from renal cell carcinoma is lower than the average daily drinking this drink less than one cup of 16%.

Glomerular filtration rate

Glomerular filtration rate (GFR) is the examination of renal function, and to determine whether there is a measure of kidney disease and disease stage. The glomerular filtration rate is too high and the increased risk of nephropathy together. A study published in the 2010 Journal of nutrition found: drink more than a cup of coffee and habits of the people of GFR to improve the level of the day. The study did not determine the consumption of coffee and kidney disease there is a link, but should do further research on this effect.
