Certain foods can lead to an eczema flare-up if you’re prone to sensitivities. Dairy, processed foods, and certain fruits and vegetables are known to be triggers for eczema symptoms in some people. Fatty meats, trans-fats, and refined sugars should also be avoided if possible as they can worsen the condition. Eating a balanced diet free from these inflammatory foods can help keep eczema flares under control and provide relief.
