| Summary: | The effect of source of dietary carbohydrate on the plasma lipid
concentrations and glucose tolerance were studied. Three women
received diets which contained 16%, 40%, and 44% of calories as
protein, fat, and carbohydrate, respectively. During the control
period of six days the carbohydrate was derived from mixed sources.
In subsequent six-day periods, 80% of the carbohydrate was supplied
alternately by sucrose (Sugar Diet) or by polysaccharides from
natural sources (Complex Diet).
Total lipids, phospholipids, triglycerides, total and free
cholesterol of the plasma were determined on the final day of each
dietary period. The plasma concentrations of total lipids, phospholipids,
and triglycerides were lowest following the Complex Diet.
On the average, the Sugar Diet produced the same concentrations of
these lipid fractions as did the Control Diet. No consistent changes
in cholesterol could be attributed to dietary carbohydrate.
Glucose tolerance tests were performed at the end of each
dietary period. In the two young subjects, glucose tolerance did not
seem to be associated with the dietary treatment. The older subject
showed impaired glucose tolerance after the diet containing complex
carbohydrate. === Graduation date: 1969
