NAFLD. Many studies are still controversial by designs, methods, amount of caffeine or type of coffee used,
measurements, different population investigated but research in this area should also focus on assessing
the potential in taking this drink, quantifying the methods and number of intakes that generate an effective
advantage. Pending further research, we can suggest that moderate consumption of 2-3 cups of coffee a day
in patients with NAFLD should be encouraged.
