Chemicals used for the chlorination of tap water can contribute to the spread of food allergies in the United States for American scientists, whose work is published in the journal Annals of Allergy, Asthma and Immunology.
As stated in the press release of the American College on Problems of Allergy, Asthma and Immunology, approximately 15 million Americans suffer from food allergies, and the number continues to grow. The researchers believe that this is due, including high doses of dichlorophenol — a chemical used in pesticides and in the chlorination of water in the water.
"This chemical is often present in pesticides used by farmers to control insect pests and weeds, as well as in tap water," — quoted in the report allergist, MD Yershou Elina (Elina Jerschow).
Scientists have measured the levels of dichlorophenol in urine 2548 participants in a large national study of health and nutrition, conducted in 2005-2006. As a result, in the experiment were included 2211 people, 411 of which have been found food allergy, and another 1,016 people have suffered allergic reactions to the stimuli of the environment.
Scientists believe that dichlorophenol in high concentrations reduces internal barriers in the body, making it prone to allergies, they believe that food allergies and "external" can be linked.
The researchers also point out that a simple replacement for bottled tap water when cooking is unlikely to solve the problem.
"Other sources of dichlorophenol, such as pesticide-treated fruits and vegetables, can also play a big role in causing food allergies," — says Yershou.
According to the Center for Disease Control in the United States, the incidence of food allergies in this country increased by 18% from 1997 to 2007. The most common allergens are the milk, peanuts, wheat, soy, fish and shellfish.
