The more milk you drink, the more likely you are to have acne — especially if it’s skim milk. Scientists are still trying to figure out why, but it could be the hormones that cows make when they are pregnant, which wind up in their milk. People who have higher levels of those hormones in their blood tend to have more acne.
2.Sugar and Some Carbs
You’re more likely to have acne if your diet is full of foods and drinks like soda, white bread, white rice, and cake. The sugar and carbohydrates in these foods tend to get into your blood really quickly. That means they are high on the glycemic index, a measure of how foods affect blood sugar. When your body makes more insulin to bring down blood sugar, it affects other hormones that can boost oil production in your skin.
