Lead poisoning - nutritional considerations; Toxic metal - nutritional considerationsDefinition Return to top
Nutritional considerations to reduce the risk of lead poisoning.
Function Return to top
Lead is a natural element with thousands of uses. Because it is widespread (and often hidden) lead can easily contaminate food and water where it is undetectable to the eye or taste.
Food Sources Return to top
Lead can be found in canned goods if there is lead solder in the cans. Lead may also be found in other some containers. See: Cooking utensils and nutrition
Old paint poses the greatest danger for lead poisoning, especially in young children. Tap water from lead pipes or pipes with lead solder is also a source of hidden lead. For more information, see: Lead poisoning disease
Side Effects Return to top
High doses of lead can damage the nervous system, kidneys, and blood system and can even be lethal. Continuous low-level exposure causes lead to accumulate in the body and cause damage. It is particularly dangerous for babies, before and after birth, and for small children, because their bodies and brains are growing rapidly.
Many federal agencies study and monitor lead exposure. The Food and Drug Administration (FDA) monitors lead in food, beverages, food containers, and tableware. The Environmental Protection Agency (EPA) monitors lead levels in drinking water.
