The key you may have learned by now is levels of caffeine and oxalates, and also other constituents like certain antioxidants which can actually be beneficial to kidney health.

The effects can be significantly stronger in the elderly, the young, and those who have a blood pressure problem.

High blood pressure is not an ideal condition for coffee drinking. The other aspect is the known link between hypertension and kidney problems. People who have high blood pressure are much more likely to develop kidney conditions down the road.

Mortality Risk Reduced By Up To 24 Percent

How coffee affects your health?

Numerous studies have hailed caffeine for its potential life-prolonging benefits, but Dr. Vieira and colleagues note that it is unclear whether or not patients with CKD may reap such rewards.

To find out, the researchers analyzed data from the 19992010 National Health and Nutrition Examination Survey, identifying 2,328 patients who had CKD.

The daily caffeine consumption of participants was assessed at study baseline, and subjects were divided into four groups based on these data:

  • first quartile, who consumed under 29.5 milligrams of caffeine daily
  • second quartile, who consumed 30.5 to 101 milligrams of caffeine daily
  • third quartile, who consumed 101.5 to 206 milligrams of caffeine daily
  • fourth quartile, who consumed 206.5 to 1,378.5 milligrams of caffeine daily

The researchers then looked at the mortality of each participant and how this was associated with caffeine intake.

Compared with subjects in the first quartile of caffeine consumption, those in the fourth quartile were 24 percent less likely to die of all causes, while those in the second and third quartile had a 12 percent and 22 percent lower risk of all-cause mortality, respectively.

According to the team, these findings remained after accounting for participants age, gender, race, blood pressure, smoking status, body mass index , and many other possible confounders.

If you suffer from kidney disease or have a history of kidney problems in your family, you may be concerned about coffee consumption.

In some ways, coffee can actually benefit your kidneys. Lets take a look at the details and see why.

Coffee and Your Kidney Health The Claims

News stories released in the past few years have claimed that coffee is bad for your kidneys because it is a diuretic.

Coffee causes you to urinate more frequently, which can leave you dehydrated without the necessary water in your system to support good kidney health.

Coffee is also a bladder irritant, which can trigger some problems with people who have both kidney disease and an underlying bladder condition.

Finally, coffee contains oxalates, which can bind with calcium to form kidney stones.

If you are in good health then drinking one or two cups of coffee each day shouldnt have any negative impact.

If you have existing kidney problems, you are likely safe when drinking coffee, but its recommended that you consult with your physician first.

Fruits, for example, have very high water content and can help you to stay hydrated.
