Many people find certain foods can trigger or intensify a rosacea flare-up. You may want to consider changing your diet to eliminate the most common food triggers, which include: alcohol, spicy foods, heated beverages, certain fruits (avocado, tomatoes, bananas, red plums, raisins, figs and citrus fruits), certain meats (liver and marinated meats), certain vegetables (spinach, eggplant, lima beans, navy beans, peas), and dairy products (yogurt, sour cream, cheese) as well as chocolate, vanilla, soy sauce, vinegar and foods high in histamine.
