library / Dioxins

Dioxins-including polychlorinated biphenyls (PCBs), polychlorinated dibenzo furans (PCDFs), and polychlorinated dibenzo dioxins (PCDDs)-are aromatic compounds that can build up in the fat of humans and animals and may increase the risk of cancer, disrupt the endocrine system and have other undesirable health effects.

The Environmental Protection Agency has categorized dioxins and research shows these compounds cause a wide range of detrimental health effects on hormone systems, fetal development, reproductive capacity and immune function.

According to the Food and Drug Administration, most dioxin exposure occurs through the diet, with over 95% coming through the dietary intake of animal fats, specifically beef, pork, poultry, fish and dairy products. The best way to avoid dioxins is to choose organic meats and poultry and "wild" fish as opposes to "farmed".
