Sumario:Aging is characterized by deterioration of biomolecules and impaired stress responses that make the elderly especially vulnerable to environmental pollutants. The pesticide p,p'-DDE is a DDT derivative that generates great concern because of its wide distribution and its harmful effects on both human health and the environment. We analyzed here the biological responses elicited by p,p'-DDE exposure in the liver of aged Mus spretus mice. Data demonstrate that the elderly constitute a population especially sensitive to this noxious environmental pollutant. We also demonstrated here that the daily consumption of sun-dried Pedro Ximénez (PX) white-grape must (PXM) protects the liver of aged mice from both the age and the damages caused by p,p'-DDE exposure. The PXM activity was exerted through the restoration of the hepatic metabolisms of lipids and carbohydrates and, probably, is a consequence of the ability of this polyphenol-rich mixture to avoid oxidative stress. Nutritional interventions including PXM, which ameliorates the effects of unavoidable exposure to pesticides in our food, are helpful tools that can help elderly populations to enjoy a healthy and expanded lifetime.
