Food Allergies Linked to Pesticides

Common food allergies in childrenEnvironmental pollution and the occurence of food allergies in the United States are on the rise. According to the Center for Disease Control and Prevention (CDC) an increase in food allergies of 18 per cent was seen between 1997 and 2007.

The increased use of pesticides and other chemicals in the environment is associated with a higher prevalence of food allergies according to a study published in the December issue of the Annals of Allergy, Asthma, and Immunology. Elina Jerschow, assistant professor of allergy and immunology at the Albert Einstein College of Medicine in New York said: “Our research shows that high levels of dichlorophenol-containing pesticides can possibly weaken food tolerance in some people, causing food allergy. ”

What are Dichlorophenols?

Dichlorophenols are widely used as pesticides and for chlorination of water. Researchers have found that people exposed to high levels of dichlorophenols, the chemical added to water to ensure it is free of bugs, tend to be more prone to food allergies. It doesn’t mean that people should stop drinking tap water to avoid dichlorophenols exposure. Even those who opted for bottled water instead of tap water could ingest the pesticide chemical from eating pesticide-treated fruits and vegetables, fruit juices and foods. This chemicals are also commonly found in pesticides used by farmers and consumer insect and weed control products.

How dichlorophenols affect our environment?

Dichlorophenols have a strong antibacterial effect that could affect microflora in the environment. Dichlorophenols are a kind of chlorine that are known to kill bacteria. A new study reported in the December issue of Annals of Allergy, Asthma and Immunology support the hypothesis that high levels of dichlorophenols can alter the population of microbes within the human body, which can affect the way that the body react to food. According to the study urine dichlorophenols level at the 75th percentile and above were associated with the presence of sensitization to foods. Excessive use of dichlorophenols may contribute to the increasing incidence of food allergies in westernized societies.

Jerschow said the research is still too preliminary to suggest that Americans should change  their eating or drinking habits.

Most common food allergens

The egg, milk, fish, shellfish, tree nuts, peanuts, soy, and wheat make up 90 percent of food allergies. Symptoms can range from mild rash to a life-threatening anaphylaxis. The American College of Allergy, Asthma and Immunology (ACAAI) recommends everyone with known food allergy to always carry two doses of allergiest prescribed epinephrine. The delay in using epinephrin can lead to death.
