I’m going to give you a few reasons why. First, I’ll show you 2 people who don’t get acne. According to scientific reports: the inhabitants of Kitavan Island in Papua New Guinea and nomadic hunters in Paraguay don’t have acne, and their diet consists mainly of fruits, fish, hunted game, and yams, rather than cereals and refined sugar. This suggests that those high-sugar carbohydrates that increase blood glucose levels (doughnuts, fritters, cookies, sugar, cakes, bread, fries) can produce a range of changes in hormone levels that can cause acne. Elevated blood sugar leads to increased insulin production, which affects other hormones and causes the skin to produce excess oil. Therefore, eating more fruits and vegetables and fewer high-sugar carbohydrates provides a preventative approach for acne sufferers.
