Skim milk may worsen teenage acne
Skim milk appears to worsen teenage acne, according to a study that shows full-cream milk is a safer bet for adolescents with skin problems.
The finding supports previous work that found an association between facial acne and skim or low-fat milk consumption.
There is no evidence to show consumption of full-fat milk or other dairy products is problematic for teenage skin.
It has been suggested that skim milk contains hormonal constituents, or factors that influence the body's own hormones, that can affect the skin.
The researchers note there are differences between full-fat and skim or low-fat milk, including overall composition of proteins, fatty acids and cholesterol molecules.
“Milk fat, although containing saturated fats, also contains numerous medium-chain fatty acids beneficial in promoting a healthy metabolism and decreasing insulin resistance,” write the authors in the Journal of the American Academy of Dermatology.
Dairy fat has also been shown to benefit metabolic profiles and allow greater bioavailability and distribution of vitamins A and D, they add.
Nonetheless, the role of diet in acne remains controversial.
The researchers say further investigation, particularly studies showing the impact of skim milk elimination, are needed before making specific dietary recommendations for patients with acne.
