Can food allergies cause eczema in adults? 

Eczema and food allergies in adults are related in that a large number of people with eczema also have food allergies. However, this varies case by case. Only someone will have eczema after having the following foods: shellfish, fish, nuts, gluten, soy products, eggs and cow’s milk. 

Having specific diets does not directly result in eczema. However, it might cause an outburst if you already have the medical condition.  

Knowing your body inside out and which foods are a best fit with you personally is best. Alternatively, here are types of anti-inflammatory food that you should have if you would like to alleviate eczema outbursts: fatty fish, quercetin-rich food such as apples, cherries, broccoli, and spinach and probiotic food such as yogurt and sourdough bread. Be mindful that eczema-friendly food can still cause outbursts for people who are allergic to them.
