Long-term Research Links Dairy and High-Sugar Foods to Acne

Link between milk and high-sugary foods to acne.

Jennifer Burris, researcher and doctoral candidate within New York University's Department of Nutrition, Food Studies, and Public Health in Steinhardt School of Culture, Education, and Human Development, says, "This change [in attitude] occurred largely because of the two important studies that are repeatedly cited in the literature and popular culture as evidence to refute the association between diet and acne.

"More recently, dermatologists and registered dietitians have revisited the diet-acne relationship and become increasingly interested in the role of medical nutritional therapy in acne treatment."

Eating high GI foods - foods that are absorbed into the bloodstream quickly - is thought to have a direct effect on the severity of acne because of the hormonal fluctuations that are triggered. High GI foods cause a spike in hormone levels including insulin which is thought to instigate sebum production. A 2007 Australian study showed that young males who were put on a strict low GI diet noticed a significant improvement in the severity of their acne.

Milk is thought to affect acne because of the hormones it contains. A 2007 study carried out by Harvard School of Public Health found that there was a clear link between those who drank milk regularly and suffered with acne. Interestingly, those who drank skimmed milk suffered with the worst breakouts, with a 44% increase in the likelihood of developing blemishes. It is thought that processing the milk increases the levels of hormones in the drink.

Choosing low GI foods

  • Only carbohydrates have a GI rating.
  • Because low GI foods take longer for the body to break down they help you feel fuller for longer too.
  • High GI foods include sugary fizzy drinks, cakes, pastries, chocolate, white bread and potatoes.
  • Low GI foods include fruit and vegetables, wholegrain options such as brown pasta, basmati rice, couscous and pulses.
  • Not overcooking your pasta and vegetables helps lower the GI.

The authors of the latest overview - published in the Journal of the Academy of Nutrition and Dietetics - say that dermatologists and dietitians should work together to design and conduct quality research to help the millions of acne sufferers.

Is there something to the statement - She just has good genes?
