The study showed that after being on a low glycaemic diet for 12-weeks, men with acne had a significant reduction in pimples, whiteheads and other lesions compared with their peers who had stuck to a more conventional diet.The other thing to note is that if you mix foods that are high on GI with those that are low on it will decrease the GI for the whole meal.
