Plasma concentrations of glucose, insulin, and fatty acids before and after an oral glucose tolerance test (24) in young and elderly participants. (A) Glucose [P = 0.10 for the area under the curve (AUC) for the elderly (16,978 ± 656) as compared with the controls (14,495 ± 1,116)]. (B) Insulin [asterisks indicate P < 0.03 for AUC for the elderly (6590 ± 853) as compared with the controls (3986 ± 519)]. (C) Fatty acids (P = 0.08 for the basal concentration of fatty acids in the elderly versus the controls).
