What foods to eat if you have acne? ?

Ok let me start here. Fruits & Veggies. OK. But for example, vitamin A is good for you. Carrots have a lot of it,BUT also are high in Glycemic(bad4u). Can some body explain this, im so confuse. Also milk. Milk has good source of calcium vitamin A, but has iodine(bad4u). Wheat. Good source of fiber, but Wheat products (wheat flour, bread, pasta, pastries, wheat cereals, nutrition bars and other foods listing wheat or flour as an ingredient) cause a sudden increase in blood sugar called hyperglycemia.This results in the production of insulin, causing insulin-induced skin inflammation within the follicles. Inflammation=acne. So what the hell is going on. I dont eat in the morninng no more cause, simply every thing is bad for the skin. WTF to eat????
