Peanut Allergy News and Research

RSS

A peanut allergy is an overreaction of the body's immune system to peanut protein. All peanut and peanut products must be excluded from the diet. This is one on the most common allergies that leads to anaphylaxis, so it is extremely important that all sources of peanut be avoided.

Discovery of special dendritic cells sheds light on food allergy prevention

The immune system must be able to quickly attack invaders like viruses, while also ignoring harmless stimuli, or allergies can result. Immune cells are known to ignore or "tolerate" molecules found on the body's own healthy cells, for instance, as well as nonthreatening substances from outside the body like food.
