Stress May Lead To Food Allergies

Stress May Lead To Food Allergies


Feeling stressed? Watch out -- you could be giving yourself food allergies.

Researchers from the University of Amsterdam have found a link between stress and food allergies, as well as other intestinal disorders.

Annette van Kalkeren, a biologist from the university, found that mice that have been subjected to stress have intestines that overreact to certain foods.

Kalkeren investigated the reaction of pieces of mouse intestine to egg albumin, a substance found in eggs. Just like humans, mice can become allergic to the substance. She found that the intestines of mice subjected to prolonged stress had more symptoms of food allergies.

The intestinal wall becomes more permeable under stressful conditions. Harmful substances penetrate the intestinal wall, which causes a panic response by the immune system. That could be the start of an allergy.

During chronic stress, the body's natural defense is weakened and allergens can penetrate deep into the body. Food allergies and various intestinal diseases, such as Crohn's disease, ulcerative colitus and irritable bowel syndrome can in part be caused or enhanced by chronic stress.

But how did the mice get stressed in the first place? Kalkeren exposed them to several "stressful environments -- including cold, extended time in a narrow tube, social isolation, and swimming.
