The interrelationships between physical measurements, dietary
intake of specific nutrients, and plasma lipids were examined in 19
healthy elderly subjects. The mean blood pressures, relative weights,
and skinfold thicknesses were within normal ranges, although women
tended to be more overweight. Systolic pressure and relative weight
were associated with increased body fatness, as measured by suprailiac
and subscapular skinfolds. On the average, the caloric intake of
these subjects was only 85% of the recommended dietary allowance;
carbohydrate supplied 48% and fat accounted for 33% of the calories.
The subjects consumed a low level of saturated fatty acids and
cholesterol but the dietary ratio of polyunsaturates to saturates was
similar to that of the typical American diet. Higher levels of dietary
fat were associated with higher intakes of saturated fatty acids and
cholesterol. The mean concentrations of cholesterol, phospholipids, and triglycerides in plasma were within the normal reported ranges;
these lipid fractions appeared to be uninfluenced by the composition of
the diet. The concentration of nonesterified fatty acids in plasma was
unusually high and positively correlated with age of the subjects.
There was also an unexplained correlation between plasma nonesterified
fatty acids and the linoleic acid content of the diet. / Graduation date: 1976
