Allergies and anti-bacterials

Children’s allergy risks might be related to anti-bacterials and preservatives

Antibacterials and preservatives in products such as soap, toothpaste and mouthwash, may be linked to an increased risk of allergies in children.

A recent study looked at the link between urinary levels of antibacterials and preservatives found in many personal-care products, and the presence of IgE antibodies found in children’s blood.

IgE antibodies are part of the body’s immune system. Their levels rise in response to an allergen, and are elevated in people with allergies.

Children with the highest levels of the antibacterial agent triclosan, had more than twice the risk of food allergies, and nearly twice the risk of environmental allergies, as children with the lowest levels.

Have we taken the fear of germs too far?
