Attention Deficit Disorder Linked to Pesticides

More than four million American children suffer from ADHD... pesticide may be contributing

For the first time, a new study links Attention Deficit Hyperactivity Disorder (ADHD) to pesticides found on the most common fruits and vegetables.

More than four million American children suffer from ADHD. It has been blamed on everything from watching too much television to simply being over-diagnosed.

The new study, published Monday in the Journal of the American Academy of Pediatrics, points to a pesticide called organophosphate, which is commonly used on produce. Researchers found this one type of pesticide may be contributing to ADHD.

Carrollton mom Rebecca Schnitzer has one son with ADHD, and she doesn't discount the latest information. "As a parent, you have to look at all different aspects of a diagnosis... taking in food, vaccinations, environment, and certainly the pesticide," she said.

Schnitzer was already buying organic fruits and vegetables, not wanting to take any chances. The researchers claim the chemicals on fruits and veggies can have harmful effects on development, including behavioral problems in children.

But Dr. Stuart Robinson of Dallas says parents who cannot afford organic fruits should wash them thoroughly and not be alarmed.

"I wouldn't take any drastic moves until the scientific community is in agreement with respect to a specific cause and effect," he said.

Researchers say your best bet for avoiding pesticides is to purchase organic produce.

Dr. Robinson said children can develop ADHD symptoms from anxiety, stress, and even sleep deprivation. "Cognitive processing deficits are common, and ... to try to demonstrate that one specific factor is causing it is going to be difficult for quite some time," he said.

One national organization that represents pesticide manufacturers thinks much more research is needed to determine whether a link actually exists, saying that pesticide used on fruits and vegetables has been registered by the Environmental Protection Agency, and when used according to the label, the EPA has determined it to be safe.

Nutritionists suggest washing fruit and vegetables in distilled vinegar — about half a teaspoon to one cup of water. Alternatively, you can use a brush to scrub produce before eating.

Researchers say your best bet for avoiding pesticides is to purchase organic produce. An Emory University study found children given organic produce had nearly undetectable levels of pesticides. To be certified "organic," food in the U.S. must be 95 percent natural.
Last month, the Department of Agriculture announced it would start enforcing rules that require spot testing for organic foods. Workers will be looking for traces of pesticides.
