A large study of over 228,000 UK adults found that following a Mediterranean-style diet was linked to lower odds of adult acne, especially in women. Meanwhile, fatty and sugary foods raised acne risk, and not all dairy is created equal — milk worsened acne while yogurt appeared protective. Experts say overall diet quality, not just avoiding specific foods, may be the smarter approach.
Your diet might be doing more than affecting your waistline — it could be shaping your skin. A new study published in the Journal of the European Academy of Dermatology and Venereology, drawing on data from over 228,000 UK Biobank participants, found that adherence to a Mediterranean-style diet was associated with lower odds of adult acne. Higher intake of fatty and sugary foods, on the other hand, was linked to a greater likelihood of breakouts.
The findings weren't one-size-fits-all. Mediterranean diet benefits were most pronounced in women, while men following a meat-heavy, low-carb diet showed higher acne odds. The dairy picture was also more nuanced than previously thought — skimmed milk and milk-based desserts were tied to higher acne likelihood, but yogurt was actually associated with lower odds, possibly due to differences in fermentation, food structure, and composition.
Key Takeaways:
Why it matters: Acne affects millions of adults, and treatment often focuses solely on topical or systemic medications. These findings suggest that counseling patients on overall dietary quality — particularly a Mediterranean-style pattern — could be a meaningful complement to standard dermatological care.
