From the moment a child arrives in our lives, we worry about whether they are thriving on the food we provide for them. Today we must consider not only the nutritional value of food, but also its source, the presence of pesticides, dyes and other chemical additives as well as processing and packaging methods that may unintentionally add plastic particles and their component chemicals. Because many children do not eat a wide variety of foods, they will have a greater exposure to the chemicals found in the few foods they do eat. A child’s body is particularly vulnerable because of its small size, rapid growth and still-developing immune, detoxification, and elimination systems.
