Some food that cause acne are chocolate has an higher risk of developing acne doesn't mean necessarily that you cant still eat it, fast food you probably already know this but eating alot of fast food/junk food can cause acne, dairy products some studies also found that young adults who regularly consumed milk or ice cream were four times more likely to suffer from acne, food that you are sensitive too can increase the amount of inflammation in the body so if you consume food you are sensitive too it can worsen your acne. hope this helped :D
