Emerging issues: nutritional awareness in environmental toxicology.

Based on recent evidence, we hypothesize that nutrition can modulate the toxicity of environmental pollutants and thus modulate health and disease outcome associated with chemical insults. For example, certain dietary fats may increase the risk to environmental insult induced by polychlorinated biphenyls (PCBs), and fruits and vegetables, rich in antioxidant and anti-inflammatory nutrients or bioactive compounds, may provide protection. Nutritional awareness in environmental toxicology is critical, because of opportunities to develop dietary guidelines which specifically target exposed populations. Nutrition may provide the most sensible means to develop primary prevention strategies of diseases associated with environmental toxicology.
