Abstract Objectives The aim of this study was to assess the validity and specificity of blood plasma and red blood cell (RBC) amino acid carbon stable isotopes ratios (AA-CIRs) as biomarkers of sugar sweetened beverage (SSB) and meat consumption in a highly-controlled feeding study. Based on previous findings, we hypothesized that SSB intake would increase the AA-CIR of alanine and other nonessential amino acids (NEAA), whereas meat intake would increase the AA-CIRs of essential amino acids (EAA). Methods We measured plasma and RBC AA-CIRs in 32 United States adult males who participated in a 12-week, fully in-patient feeding study between 2011 and 2018. Each participant was randomly assigned to one of eight diets, which manipulated the intakes (presence/absence) of SSB, meat, and fish in all possible combinations while maintaining a macronutrient distribution of 50% carbohydrate, 30% fat, and 20% protein at a weight-maintenance level. Fasting blood samples were collected biweekly throughout the study. Plasma and RBC AA-CIRs were measured using n-acetylmethyl ester derivatization and gas chromatography-combustion-isotope ratio mass spectrometry. We examined final week AA-CIRs as a function of the three variable intakes and baseline values from samples collected at the start of the study, and we used a Bonferroni-adjusted α = 0.0007 to assess significance. Results In general, our results supported our hypothesis that NEAA-CIRs were elevated by SSB intake, whereas EAA-CIRs were elevated by meat intake. In plasma, the CIR of the NEAA alanine was elevated with the intake of SSB but not of meat or fish. In RBC, the CIRs of alanine and glutamine/glutamic acid were elevated specifically with SSB. However, the CIR of alanine in RBC had a smaller effect size than in plasma and was also significantly associated with baseline values. Three EAA-CIRs (leucine, isoleucine, and threonine) increased with meat intake in plasma, but not in RBC, and did not respond to SSB or fish intake. Two EAA-CIRs (valine and phenylalanine) measured in RBC were associated with baseline. Conclusions This highly-controlled study suggests that the AA-CIR of plasma alanine is a promising biomarker of SSB intake in United States diets. The CIRs of essential AAs may have potential as biomarkers of meat intake. Funding Sources NIH NIDDK.

Background: Sugar-sweetened beverage (SSB) intake is associated with higher risk of weight gain, diabetes, hypertension, cardiovascular disease, and cardiovascular mortality. However, the association of SSB with subclinical atherosclerosis in the general population is unknown. Objective: Our primary objective was to investigate the association between SSB intake and prevalence of atherosclerotic plaque in the coronary arteries in The National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study. Methods: We studied 1991 participants of the NHLBI Family Heart Study without known coronary heart disease. Intake of SSB was assessed through a semi-quantitative food frequency questionnaire. Coronary artery calcium (CAC) was measured by cardiac Computed Tomography (CT) and prevalent CAC was defined as an Agatston score ≥100. We used generalized estimating equations to calculate adjusted prevalence ratios of CAC. A sensitivity analysis was also performed at different ranges of cut points for CAC. Results: Mean age and body mass index (BMI) were 55.0 years and 29.5 kg/m2, respectively, and 60% were female. In analysis adjusted for age, sex, BMI, smoking, alcohol use, physical activity, energy intake, and field center, higher SSB consumption was not associated with higher prevalence of CAC [prevalence ratio (95% confidence interval) of: 1.0 (reference), 1.36 (0.70–2.63), 1.69 (0.93–3.09), 1.21 (0.69–2.12), 1.05 (0.60–1.84), and 1.58 (0.85–2.94) for SSB consumption of almost never, 1–3/month, 1/week, 2–6/week, 1/day, and ≥2/day, respectively (p for linear trend 0.32)]. In a sensitivity analysis, there was no evidence of association between SSB and prevalent CAC when different CAC cut points of 0, 50, 150, 200, and 300 were used. Conclusions: These data do not provide evidence for an association between SSB consumption and prevalent CAC in adult men and women.
