Acne is an internal problem that shows external symptoms. When you eat foods that cause an insulin spike, unecessary hormones are released during it. Your body is then not able to detoxify these hormones because it is busy enough working on toxins and necessary hormones no longer needed. People are unaware what causes an insulin spike to happen. High sugar foods, moldy foods, high unecessary fat foods, and wheat can cause a spike. Yes wheat is not good for your body. Your body does not care that the bag of bread says 100 percent whole wheat and whole grain it turns it into sugar when you eat it.
