You may have noticed lately that the number of people, especially children, with food allergies is increasing. With common allergens such as wheat, soy, peanuts, tree nuts, eggs, milk (and milk products), fish, and shellfish, you may wonder why so many people have allergies.
On December 3, 2012, the results of a study were released which tested the hypothesis that chemicals, specifically pesticides, in our drinking water may increase food allergies. The study did not find the two were linked. However, this same study did find (to no surprise) that both environmental pollution and food allergies are increasing in the USA.
The researchers found that while pesticides in water do not directly cause food allergies, the increase in chemicals in the water is associated with more food allergies. This study surveyed over 10,000 Americans regarding their health. Researchers analyzed the participants’ urine and determined that dichlorophenol, a chemical used in pesticides, weed-killers, and as a method of chlorinating water, was at measurable levels in over 2200 participants. Of those individuals, over half reported having either a food allergy or an environmental allergy (such as pollen). This information led the researchers to believe dichlorophenols may weaken food tolerance in some people, causing a food allergy. This could also explain why some children outgrow food allergies and why some adults develop them later in life.
Researchers did say that they cannot draw any specific conclusions on the link between pesticides in drinking water and food allergies, but there is enough evidence to warrant more research and more studies. Until we know for certain, it is recommended pregnant women, children, and those with a compromised immune system drink distilled or filtered water to help reduce the risk of developing or aggravating a food allergy.
