USA – Milk could be one of the causes of acne, according to new research.

The study was based on responses to a survey from more than 47,000 women involved in an ongoing health study.

Women who drink two or more servings of skimmed milk every day are 44 per cent more likely to have developed severe acne, the study reported in the Journal of the American Academy of Dermatology. Women who drink more than three daily servings of any type of milk are 22 per cent more likely to have suffered from acne.

The researchers say the association with milk may be because of the presence of hormones and bio-active molecules in milk.
