Understanding Rosacea · Chapter 7
Diet
Diet attracts strong opinions in rosacea. This chapter separates the evidence from anecdote, covering the gut-skin connection, dietary patterns and specific foods and drinks.
Is there a rosacea diet?
There is no single proven rosacea diet. A 2024 study found that people who closely followed a Mediterranean diet responded better to treatment, especially topical treatment, so a Mediterranean-style eating pattern is a sensible, low-risk choice.
Is rosacea linked to gut health?
Small intestinal bacterial overgrowth (SIBO) is more common in people with rosacea, and in one study treating it led to marked skin improvement. If you have persistent bloating or bowel changes alongside rosacea, mention them to your doctor.
Does alcohol cause rosacea?
A large study of US women found that higher alcohol intake was linked to a greater risk of developing rosacea, not just flares. The strongest links were with white wine and spirits rather than red wine.
Which foods trigger rosacea?
Common culprits are spicy food and hot drinks, foods containing cinnamaldehyde (cinnamon, tomatoes, citrus, chocolate) and histamine-rich foods such as aged cheese and cured meats. Reactions are individual, so test one food at a time.
Key takeaways
- A Mediterranean-style diet may support treatment.
- Persistent gut symptoms are worth mentioning to your doctor.
- Alcohol raises the risk of developing rosacea.
- Diet supports treatment but does not replace it.
