American scientists have found that chemicals used in the process of chlorination of tap water can cause the spread of food allergies in the United States. Information researchers have been published in the journal Annals of Allergy, Asthma and Immunology.
According to a press release from the American College on Problems of Allergy, Asthma and Immunology, food allergies affect about 15 million American citizens, and that number continues to grow rapidly. The scientists claim that this is also due to high doses of the chemical, as dichlorophenol, widely used in pesticides, as well as the chlorination of tap water.
"This chemical is often found in pesticides used by farmers to control weeds in the fields, insect pests, but also in tap water," - said Elina Yershou, an allergist and doctor of medical sciences.
In the course of a large national study conducted in 2005-2006 in the field of health and nutrition scientists has been measured in the urine level dichlorophenol 2,548 volunteers. As a result, the experiment was attended by 2,211 people, 411 of whom have been identified food allergy, the other 1,016 people were exposed to manifestations of allergic reactions to stimuli from the environment.
Dichlorophenol in high concentrations, according to scientists, the body weakens the internal barriers, making it more susceptible to allergies. Researchers believe that the food and the "external" allergy may be linked.
The scientists also stressed that the normal attrition of bottled water tap for cooking will not solve the problem.
"The emergence of food allergies can also cause dichlorophenol other sources, such as fruits and vegetables treated with pesticides," - says Yershou.
According to the Centers for Disease Control in the United States, the number of incidences of food allergies has increased by 18% from 1997 to 2007 in this country. The most common allergens are considered foods such as milk, soy, peanuts, wheat, fish and shellfish.
