Postprandial Levels of Branch Chained and Aromatic Amino Acids Associate with Fasting Glycaemia

Table 4

Robust linear regression of HOMA-IR clustered on participant ID (), adjusted for age and sex. Metabolites are overnight fasting plasma concentrations and 180-minute postprandial AUC in 21 individuals at four different occasions. Beta values reflect increment of HOMA-IR per standardized unit of DMAA. CI: confidence interval.

Metabolites	Beta (95% CI)		Beta (95% CI)
	Fasting concentrations		180 min postprandial AUC
DMAA score	0.26 (0.13–0.39)	<0.001	0.14 (0.04–0.24)	0.008
Phenylalanine	0.26 (0.08–0.44)	0.0053	0.16 (0.08–0.25)	0.001
Tyrosine	0.24 (0.13–0.36)	<0.001	0.10 (0.01–0.20)	0.048
Isoleucine	0.06 (−0.08–0.19)	0.41	0.12 (0.04–0.20)	0.004
