Dental health status may influence nutrition. The objective of this part of
the National Diet and Nutrition Survey was to assess if there is a relatio
nship between dental status in people 65 years and older and intake of cert
ain nutrients and any link between dental status and blood-derived values o
f key nutrients. Random national samples of independently living subjects a
nd those living in institutions had dental examinations, interviews, four-d
ay food diaries, and blood and urine analyzed. In the sample living indepen
dently, intakes of most nutrients were lower in edentate than dentate subje
cts. Intake of non-starch polysaccharides, protein, calcium, non-heme iron,
niacin, and vitamin C was significantly lower in edentate subjects. People
with 21 or more teeth consumed more of most nutrients, particularly of non
-starch polysaccharide. This relationship in intake was not apparent in the
hematological analysis. Plasma ascorbate and plasma retinol were the only
analytes significantly associated with dental status.
