Can whole grain bread cause inflammation in whiteheads acne or agrevate those whiteheads?

No evidence for that: Whole grain breads can be a rich source of important complex carbs that our bodies need to stay healthy. However, if you are gluten sensitive, you may want to stay away from wheat, barley, and rye breads for these can cause a variety of G.I. Symptoms. I have not seen anyone that developed worsening acne by eating whole grain breads nor have i been taught this by dermatologists.
