Decaf coffee is very popular among people trying to limit their caffeine intake
However, in reality, decaf does not “truly” exist. The decaffeination process only removes around 95% of the caffeine in coffee beans. Therefore, decaf still contains, on average, about 2-14 mg of caffeine per 8-ounce (236-ml) cup.
Coffee in general is known to have certain health benefits. For one, it can lower your risk of developing type 2 diabetes. However, studies show that decaffeinated coffee only provides about half the risk reduction for diabetes compared to regular coffee. This suggests most health benefits of coffee are related to the chemical balance between the natural caffeine in the coffee beans and it’s interaction with the various other vitamins and minerals within the beans.
On the plus side, decaffeinated coffee contains similar amounts of antioxidants and nutrients as regular coffee. Overall, decaf has equal or less health benefits to regular coffee. There are also no known heath risks to decaf that are not equal or greater to regular coffee. For people with high sensitivity to caffeine or preexisting heart problems, decaf may be a safer alternative, though not any healthier.
