Even though coffee is one of the world’s most popular beverages, many coffee lovers opt for decaf coffee because they want to limit their caffeine intake for some reason. So, technically, decaf coffee is just like regular coffee, except the caffeine has been removed. In fact, the decaffeination process won’t take away the nutritional value of the coffee beans, apart from the caffeine content. However, the taste and smell may become a little milder and the color may change, depending on the method used. Nutritionally, decaf coffee may reduce the risk of type 2 diabetes. It may also reduce the risk of premature death.
