Besides spicy foods like chili, foods such as potatoes and white bread can also trigger or worsen acne; conversely, high-fiber fruits and vegetables will make your face look clearer.
Dr. Smith, a researcher, divided men with acne problems into a low-sugar diet group and a normal diet group. In the low-sugar diet group, 45% of the energy came from low-glycemic index foods; people in the normal diet group ate high-glycemic index foods such as white bread and potatoes. After 12 weeks, the researchers found that the acne in the low-sugar diet group had significantly improved; while the normal diet group showed no improvement.
