When you click on 'Dr Google' to research possible triggers for atopic eczema/dermatitis, the main ones that come up are dairy, eggs and sugar, but did you know that the Nightshade family (tomatoes, potatoes, peppers and aubergines) are a common trigger? A 2017 study (Nosrati et al.,) found that 51.4% of participants found symptom relief following exclusion of members of the Nightshade family.
All eczema sufferers, just like all humans are different - did you know that you can react to one member of the Nightshade family but not all? One of my client's is unable to tolerate tomatoes and aubergines but is fine with potatoes and peppers. So the key is to closely monitor your own reactions and not assume that whole families of foods need to be excluded.
