Pj. Moynihan et al., INTAKE OF NONSTARCH POLYSACCHARIDE (DIETARY FIBER) IN EDENTULOUS AND DENTATE PERSONS - AN OBSERVATIONAL STUDY, British Dental Journal, 177(7), 1994, pp. 243-247
Compromised masticatory efficiency places edentulous persons at risk o
f consuming a diet low in non-starch polysaccharide (NSP) ('dietary fi
bre'). No study has quantified NSP intake in edentulous people using a
valid and reliable method of dietary assessment. The aim of this stud
y was to provide quantitative data on NSP intake of edentulous persons
, together with information on its dietary sources. Using the dietary
history method, habitual intake of NSP was compared between edentulous
persons (n = 30) and dentate persons (n = 30) between the ages of 40
and 60. Groups were matched for sex and social class. The edentulous g
roup had a median NSP intake of 73 (31-211) g/week. This was significa
ntly lower than that of the dentate group of 106 (25-225) g/week (P =
0.014). Neither group completely met current UK guidelines. NSP intake
of 56% (n = 17) of the edentulous group was below 84 g/week, whilst 1
7% (n = 5) of the dentate group was below this figure - a level of int
ake below which increased occurrence of gastrointestinal complaints ha
s been observed. The dentate group obtained significantly more NSP fro
m all rich sources, including wholemeal breads, cereals, vegetables an
d fruit. Depending on their form and preparation, such foods are not n
ecessarily difficult to chew. Specific advice on food selection is req
uired to ensure the edentulous patient has an adequate intake of NSP.
Education of the dentist for this purpose is of paramount importance.
