Fat was found to enhance the absorption of lead in animal studies but these results have not been replicated in children. The Centers for Disease control and the U.S. Department of Agriculture caution against putting children under two on a low fat diet. Children under two years of age need a higher fat intake for growth and nerve and brain development. Parents should be encouraged to provide choices that will support the development of a healthy lifestyle. Snacks like fruit, whole grain crackers, popcorn, and raw vegetables are preferred.
Water is a less significant contributor to lead toxicity than lead-based paint and dust.
The lead concentration in water will be increased by using water from the hot water tap, boiling water, or softened water. Water sitting in the pipes picks up more lead. Run water for 30 seconds to 2 minutes before using it for drinking or food preparation if there is reason to believe that lead is in the water. Some folk remedies contain lead. In the United States, lead soldered cans for food have been replaced by two piece seamless cans or cans with electrically welded seams.
