Foods that Trigger Rosacea

7. Chocolate

Unfortunately for chocolate lovers, the delicious dessert contains cinnamaldehyde, a known rosacea trigger. It is thought that this compound activates a rosacea signaling pathway in people with a genetic predisposition to the condition. Although all chocolate contains the compound, milk chocolate seems to trigger more pronounced symptoms than dark chocolate. Researchers think this is due to the added sugars in milk chocolate, which cause inflammatory reactions in the body. Cinnamaldehyde is also found in cinnamon, tomatoes, and citrus.
