Tomatoes, shellfish, and other histamine-related foods
About 16 million Americans have rosacea, a chronic inflammatory skin disease (with no known cause) that is characterized by slow-developing facial redness, flushing, and/or acne-like papules or pustules. Some sufferers may be sensitive to foods high in histamine, such as citrus fruit and nuts, and/or histamine-releasing foods, such as tomatoes and shellfish, because “histamine causes your blood vessels to swell, or dilate… contributing to a wide range of problems,” according to MindBodyGreen.com. Taking an antihistamine prior to a meal of histamine-containing foods may lessen skin-reddening side effects.
More than one in every five rosacea sufferers noted that chocolate was one of their food triggers, according to survey data from the National Rosacea Society. The theory: Theobromine—the main alkaloid found in cocoa—dilates blood vessels and increases blood circulation, which contributes to skin flushing. These are the 12 things you should never, ever do to your skin.
