Drinking coffee protects kidneys? Study: 3 cups a day reduces acute kidney injury by 22%
Drinking coffee every day protects kidneys? Study: Reduce acute kidney injury
Drinking coffee isn’t just good for your heart, it’s also good for your kidneys? A generational study published in “Kidney International Reports” shows that people who drink coffee every day have an average 15% lower risk of acute kidney injury (AKI), while people who drink 2-3 cups of coffee a day have a lower risk of acute kidney injury. Up to 22%-23%.
Acute kidney injury refers to acute damage to kidney function, or accelerated deterioration of kidney function in a short period of time. It is defined as an increase in serum creatinine greater than or equal to 0.3 mg/dl within 48 hours. Not only does it increase patient mortality, it may even require long-term dialysis (kidney dialysis) during hospitalization and after discharge.
Symptoms of acute kidney injury usually vary from disease to disease. Patients may experience less urine, swelling around legs, ankles and eyes, fatigue, shortness of breath, confusion, nausea, chest pain, etc. In severe cases, it may cause seizures and coma. Commonly seen in hospitalized populations with kidney disease and postoperative complications.
Is coffee good for the kidneys? Is it best to drink 3 cups a day?
Chirag Parikh, the corresponding author of the study and director of the Department of Nephrology at Johns Hopkins University, said that this study statistics used data from the U.S. Atherosclerosis Risk Study in Communities (ARIC) to track 14,207 people aged 45 to 64 years old. For adults, their eating frequency questionnaires were collected and analyzed.
After excluding influencing factors such as gender, age, education, lifestyle and other factors, it was found that compared with people who never drink coffee, the risk of acute kidney injury is reduced by 15% for people with coffee drinking habits who drink more than 3 cups a day. Coffee drinkers had a reduced risk of acute kidney injury of up to 22%.
Studies claim that the reduction in coffee intake and acute kidney injury may be related to the bioactive compounds in coffee, or it may be related to caffeine reducing renal oxygen consumption and helping to maintain a healthier glomerular filtration rate and renal blood flow.
Studies have pointed out that caffeine may affect renal function through various mechanisms, such as increasing sodium metabolism, improving the action of the renin-angiotocin-aldosterone system (RAAS), and affecting renal tubular protein absorption. These mechanisms are all related to Related to renal oxygen consumption.
Drinking coffee helps reduce oxidative stress. Additives. Pay attention to calories and sugar.
However, the mechanism between habitual coffee and the prevention of chronic kidney disease is unclear, and larger studies are needed to evaluate the safety and impact of caffeine intake on groups at high risk of renal impairment or acute kidney injury. Renal blood perfusion.
Although the study supports that caffeine may have beneficial effects on kidney health, Chirag Parikh still reminds that the study is based on the amount of pure coffee (black coffee) consumed by the subjects. If the coffee contains too many additives such as milk, lactose, milk Refining, sugar, and sweeteners may affect the results, and may also increase the intake of sugar and calories.
The New England Journal of Medicine also published a comprehensive study on coffee intake and chronic diseases. From 95 studies, it was found that consuming 2-5 cups of coffee per day can achieve the greatest health benefits. The study pointed out that after drinking coffee, So the health benefits actually come from a combination of phytochemicals, magnesium, potassium, vitamin B and other ingredients other than caffeine, which can reduce the body’s oxidative stress and improve metabolism.
