[BDSP. Notice produite par INIST-CNRS R0xHmD89. Diffusion soumise à autorisation]. Carbon isotopic signatures ("delta13C") might reflect consumption of corn-and cane-based sweeteners. The authors hypothesized that the delta13C value of human serum is higher for individuals with high versus low intakes of corn-and cane-based sweeteners (measured as sweetened beverage intake). They conducted a cross-sectional study within the Atherosclerosis Risk in Communities Magnetic Resonance Imaging study (Maryland, 2005-2006). Diet was assessed by food frequency questionnaire, and blinded serum samples were assayed by natural abundance stable isotope mass spectroscopy. Studied were 186 participants (53% male ; mean age, 71 years ; mean body mass index, 30 kg/m2). Serum delta13C values for individuals with high sweetened beverage intakes were significantly higher than for those with low intakes (-19.15 vs. - 19.47, P
