High-Fiber Diet May Protect Against Harmful Health Effects of PCBs

Two new NIEHS-funded Superfund Research Program (SRP) studies showed how a type of dietary fiber, inulin, may protect against heart disease, including heart disease resulting from exposure to polychlorinated biphenyls (PCBs). Inulin is found in vegetables such as asparagus and onions. According to University of Kentucky SRP Center researchers, a diet high in inulin may reduce or modify certain lipids associated with an increased chance of developing cardiovascular problems and may protect against adverse cardiovascular effects caused by environmental toxicants, such as PCBs.
