Milk, cheese, yoghurt and other dairy products are one of the most common allergy food in eczema. These foods can cause sensitivity to your stomach lining, causing inflammations which can cause larger, undigested allergens to be absorbed. Yoghurts, particularly are to be avoided as they also contain high amount of sugar, preservatives and additives.
Chicken egg is another common trigger for a lot of eczema sufferers. It is best to avoid all eggs at first, although in some cases, quail, goose and duck eggs can still be tolerated. An egg allergy can cause increased levels of histamine in the body. The immune system doesn’t recognize the proteins found in eggs as safe so it attacks them to ward them off, which leads to an increase in the histamine level, causing an eczema outbreak.
Sugar can be a pro-inflammatory in the body, a contributing factor in eczema. There are a lot of cases where patients with eczema suffer from bad gut bacteria and fungus, which feeds off sugar. When these bacteria and fungus overproduce, they cause inflammation to the intestinal lining, which can cause eczema flare ups.
Certain acidic fruits like oranges, tomatoes, lemons, and strawberries are known to set off outbreaks of eczema. Many eczema sufferers experience a worsening of eczema symptoms when they eat amine and salicyclate-rich foods like these acidic fruits.
Food additives and preservatives can also cause eczema. These are likely found in prepackaged and processed foods and include tartrazine (lemon yellow azo dye, used in food coloring), sodium benzoate, sodium glutamate (salt) and sulfites (fruit preservative). MSG (monosodium glutamate, used as a food additive to enhance flavor) may also trigger or worsen eczema.
