n = 32. Results are presented as regression coefficients and SEs. Coefficients for dietary intakes refer to presence/absence. R2 presented is the adjusted R2 for the full model. Significant P values (≤0.010) were significant based on the Benjamini-Hochberg correction for the total number of comparisons across both sample types and a false discovery rate of α = 0.05. CIR, carbon isotope ratio; EAA, essential amino acid; NEAA, nonessential amino acid; SSB, sugar-sweetened beverage.

CIRThr reported in plasma only due to high measurement error in RBCs.
