Nutrition may influence toxicant susceptibility of children and elderly

Dietary deficiencies are particularly evident in young children and the elderly. Both high and low income groups show evidence of low levels of calcium, iron, and copper; these deficiencies are even greater for high income children. Animal and human studies have shown that these nutritional deficiencies can make humans more susceptible to environmental toxins. This creates higher risks for particular populations, including farm workers exposed to pesticides, and children with iron deficiency anemia, who tend to absorb more environmental lead. Good nutrition throughout life is a necessary means of reducing risks from these toxins.
