From chips down to take out pizza, junk food is part of everyday life. However, if you want to have better skin, it’s a good idea to at least minimize your junk food intake. Processed carbs and high-glycemic foods cause the insulin in your bloodstream to rise. Insulin, on the other hand, stimulates oil-producing hormones which, with blocked pores, can cause acne. Make healthier choices by replacing junk food with a high-fiber and high-protein diet. Although, you can enjoy eating a slice of pizza every once in a while.
