What foods aggravate eczema?

That depends..: ...Entirely on the person. Eczema is an allergy related condition. Whatever the individual person is sensitive to could potentially aggravate it. Conversely, what someone is not sensitive to will not aggravate it. What aggravates one person's condition may or may not aggravate another person's condition, depending on the other person's particular sensitivity.

Depends: There is evidence to suggest that moderate/severe eczema in early childhood could be worsened by certain foods (usually highly allergenic foods like peanut, tree nuts, milk, eggs, etc.). Food triggers are not usually an issue with adult eczema. If you notice a consistent pattern of worsening eczema with a particular food then by all means avoid it. See Allergist for more details and testing.
