Author Information
Author(s): Ward Mary H., de Kok Theo M., Levallois Patrick, Brender Jean, Gulis Gabriel, VanDerslice James, Nolan Bernard T.
Hypothesis
Is there a correlation between drinking water nitrate exposure and health outcomes like cancer and methemoglobinemia?
Conclusion
The study suggests that raising the drinking water nitrate limit could increase exposure to harmful compounds and health risks.
Supporting Evidence
- High nitrate levels in drinking water can increase the risk of certain cancers.
- Vegetables high in nitrate can lead to the formation of potentially harmful compounds in the stomach.
- Some studies found elevated risks associated with water nitrate levels below the regulatory limit.
Takeaway
Eating vegetables high in nitrate is common, but too much nitrate in drinking water can be harmful, especially for babies.
Methodology
The study reviews existing literature and discusses the need for well-designed studies to evaluate nitrate exposure risks.
Limitations
There are too few well-designed studies to draw definitive conclusions about the risks associated with nitrate exposure.
