### Can Certain Foods Cause Flare-Ups in People with Atopic Dermatitis? Yes, certain foods can indeed trigger flare-ups in people with atopic dermatitis (AD). Common culprits include peanuts, eggs, and milk. These foods can cause food allergies or sensitivities, which can worsen AD symptoms like itchy, red skin. About one-third of people with severe AD also have food allergies, especially children, though some may outgrow them. #### The Link Between Food Allergies, Sensitivities, and AD People with AD have a weakened skin barrier, making them more sensitive to both environmental and food allergens. Even if you don't have a full-blown food allergy, you might still have a food sensitivity, which can make your eczema worse or cause other symptoms like rashes, upset stomach, or diarrhea. #### Identifying Food Triggers Pinpointing a food sensitivity can be tricky because symptoms may not appear immediately. They can show up minutes, hours, or even days after eating the trigger food. If you suspect a food is causing your AD flare-ups, consult a dermatologist before trying an elimination diet. This diet involves cutting out suspected foods for several weeks and then reintroducing them one by one to see if symptoms return. #### Managing AD with Diet While eliminating trigger foods can help, it's not a cure-all for AD. Traditional eczema treatments should be your first line of defense. Once your AD is under control, you can try a diet that's easier on your digestive system. Reducing spicy or acidic foods and eating a balanced diet rich in vegetables, fish, and nuts, like the Mediterranean diet, may help improve your symptoms. #### When to See a Doctor If you think your diet is affecting your AD, see your dermatologist. They can help you manage your symptoms with traditional treatments and guide you through dietary changes if needed.
