The journal Pediatrics reports that there appear to be links between commonly used pesticides and the rising rates of ADHD in children. Some pesticides work by attacking the nervous systems of insects. But these pesticides attack the nervous systems of human beings as well.
"Children with a ten-fold increase in metabolites from the pesticide malathion (found in head lice treatments) were 55 percent more likely to be diagnosed with ADHD, and those with higher than average levels of metabolites from dimethyl thiophosphate were 93 percent more likely to have ADHD compared to those with undetectable levels of this marker."
Berries, especially blueberries and strawberries, are often highly tainted with commonly used pesticides. Buying organic foods is one big step towards protecting your children from pesticides. Avoiding processed foods as much as possible will also protect your children from numerous chemicals having an unhealthy link with ADHD in children.
Switching from commercial cleaning products and personal care products can also help to protect your children, as will avoiding bug repellants containing Deet.
