Coffee is a beloved beverage enjoyed by millions around the globe, with many relying on its invigorating effects to kickstart their day. However, for individuals sensitive to caffeine or those advised to limit their intake, decaffeinated coffee has emerged as a popular alternative. While decaf coffee offers a guilt-free way to indulge in the rich flavors of traditional coffee, questions often arise about its potential impact on kidney health. This article will comprehensively explore whether decaf coffee is bad for your kidneys, the science behind it, and what you should consider as a coffee drinker.
Understanding Decaf Coffee
Decaffeinated coffee is not entirely devoid of caffeine; it typically contains about 2-5 mg of caffeine per 8-ounce cup compared to the 95 mg found in a regular cup of coffee. The decaffeination process involves removing most of the caffeine from raw coffee beans while attempting to preserve their original flavor.
