Total Dietary Fiber, and Selected Vegetable, Fruit, Legume and Cereal Fiber Intake and Risk of Heart Attack in Periodontitis Subjects

摘要

Background: Epidemiological studies have found an association between periodontal disease and coronary artery disease(Arbes, Slade et al. 1999; Beck, Elter et al. 2001; Genco, Offenbacher et al. 2002), and have even implicated periodontal disease as a risk factor(Arbes, Slade et al. 1999; Beck, Elter et al. 2001), however have not proven causality(Hujoel, Drangholt et al. 2000). Although dietary amounts, sources, and types (soluble versus insoluble) of fiber have been shown to reduce the risk of heart attack (Liu, Buring et al. 2002; Negri, Vecchia et al. 2003), this author is unaware of studies that have examined the association between food sources of dietary fiber and heart attack risk in subjects with periodontitis. This study was designed to determine whether total dietary fiber and fiber from different plant sources (vegetables, fruits, legumes, or cereals) modified self-reported HA risk, as well as acute-phase inflammatory responses in subjects with periodontitis using NHANES III data.
