Tree Nut Allergy

Tree nut allergy is an immune reaction in which the body makes IgE antibodies against proteins in nuts such as almonds, cashews, walnuts and pistachios, and it can trigger severe, life-threatening reactions. Probiotics, vitamin D and omega-3 fatty acids have all been looked at because of their possible effects on the immune system, but little research on them for this allergy has been reviewed here so far. The evidence for each is limited, so none can be pointed to as a clear help.
