Study Links Mediterranean Diet to Reduced Adult Acne Risk

The researchers examined data from the UK Biobank, analyzing the dietary habits of participants aged 37 to 73 in relation to acne prevalence, an area that has not received as much attention compared to adolescent acne issues.

Acne is a common inflammatory skin condition often seen during adolescence, but it can continue or emerge in adulthood. Previous studies primarily focused on younger individuals and the effects of specific foods, such as dairy and high-glycemic-index items.

The study involved 228,757 participants whose medical records allowed researchers to categorize them based on current or past acne experiences. Dietary questionnaires and food-recall assessments were utilized to measure overall diet quality and specific food group consumption.

Findings indicated a link between higher diet quality and lower rates of adult acne, particularly among women. Women consuming more plant-based foods showed a notable decrease in acne prevalence.

For men, diets rich in animal products, particularly meat, and lower in carbohydrates were associated with higher acne prevalence. In contrast, increased intake of cooked vegetables, yogurt, and cheese corresponded with a reduced prevalence of the skin condition.

Differing associations regarding dairy products were also noted: skim milk and milk-based desserts were linked to higher acne rates, whereas yogurt and cheese were associated with lower rates. Additionally, pork consumption showed a correlation with increased acne prevalence among men.

These findings suggest that dietary quality may influence adult acne, with varying effects between genders. However, as the research is observational, it underscores associations rather than causation regarding specific foods or diets.

Lead author Bochen Li emphasized that the identified gender differences could eventually inform more tailored dietary recommendations. She also pointed out the contrasting impacts of different dairy types on skin health, indicating a need for further research.

Co-author Wendy Hall noted that participants with acne generally maintained less healthy diets overall, suggesting the importance of considering broader dietary patterns rather than isolating individual food impacts. The researchers call for additional studies to explore whether dietary changes might prevent or alleviate acne symptoms and how sex-specific dietary guidance could contribute to better management of the condition.
