A diet rich in sugar can cause acne?

Any relationship between sugar and acne have been discarded long ago. But now scientists are re-examining the issue.
In recent years, studies have shown that the real importance may not be the sugar itself, but the glycemic index of food, ie the speed and extent to which it increases the level of glucose in the blood. Foods with high glycemic index - and therefore able to raise the levels of glucose quickly - take the body to release a stream of insulin and other hormones, which the suspicions of some scientists, are able to stimulate the production of oil and inflame the skin.

To verify the theory, scientists recruited 50 men and boys, aged between 15 and 25 years, all with acne, and followed their progress for twelve weeks. Some participants followed hyperglycemic diet rich in foods such as white bread, cereal with sugar and weight, while others received more protein and foods with lower glycemic scale, such as fish, brown bread and fruit.

At the end of the study, published in 2007, participants in the group of hypoglycemic diet had a greater reduction in skin lesions and other symptoms of acne in relation to the control group. They also showed reductions in levels of circulating androgens and free, the male hormones known to cause acne. This suggests that hormones play, but a role in the process. Other studies found similar relationships between food and acne hyperglycemic, despite the claim of scientists that is necessary to search deeper.

Conclusion: there is some evidence that foods rich in sugar may worsen the acne.
