Coffee harms the kidneys if the amount of drink per day exceeds three cups - scientists Medical researchers investigated how daily coffee consumption affects kidney health. It turned out that in a certain amount of caffeine can lead to disastrous effects..

This is reported by the resource Eat This, Not That.

New study shows that drinking three or more cups of coffee a day can harm your kidneys.

The study, which was recently published in the JAMA Network Open, followed 1,180 adults aged 18 to 45 who had incurable high blood pressure..

The study lasted approximately 16 years, each participant was tested for seven and a half years.. Scientists looked for hyperfiltration - a glomerular filtration rate that is considered higher than normal, albuminuria (too much albumin in the urine) and hypertension - all of these factors are common signs of kidney disease..

Scientists noticed that one variant of the gene was present in about half of the participants. This meant that their bodies weren't metabolizing caffeine as quickly as they could..

They also found that they were 2.7 times more likely to get kidney dysfunction if they drank 3 or more cups of coffee daily.. They were also 2.5 times more likely to develop hyperfiltration, 2.7 times more likely to develop albuminuria, and 2.8 times more likely to experience hypertension..

At the same time, scientists say that the study did not take into account other dietary factors that affect kidney health.. Therefore, it is possible that people who drink more coffee are eating fewer fruits and vegetables and more animal protein, and this negatively affects kidney health..

Scientists also note that the effect of coffee is quite individual.. Some people who drank 1 cup of coffee had blood pressure normalized. Another group of people got a similar effect from 3+ cups of coffee..

“Coffee contains antioxidants and micronutrients such as potassium, which may be helpful in protecting kidney function as well as maintaining normal blood pressure.. And a 2020 review showed that coffee is good for protecting the kidneys,” says nutritionist Jen Hernandez..

She also adds that it's best to consume coffee in moderation if you want to enjoy the benefits it can provide.. And for those who still want to play it safe from kidney disease, it is advised to drink decaffeinated coffee https://golos. ua/ Keywords:.
