Effects of sugar consumption on plasma adropin concentrations.
(A) The change (Δ) in plasma adropin concentrations is shown for males (M, N = 43) and females (F,N = 39) who consumed glucose (N = 28; 15M, 13F), fructose (N = 28; 15M, 13F) or HFCS (N = 26, 13M, 13F) for 2 wk (Study A). (B) There was no significant effect of sex; data grouped by sugar type only are also shown. (C) Change (Δ) in plasma adropin concentrations is shown for males (M, N = 15) and females (F, N = 16) who consumed glucose (N = 14; 6 M, 8 F) or fructose (N = 16; 9M, 8F) for 10 wk (Study B). (D) There was no significant effect of sex; data from Study B grouped are also shown grouped by sugar type. (E–F) Data pooled from Study A and B for the glucose and fructose groups. (E) Males (M, N = 45) and females (F, N = 42) exhibited similar responses to glucose (N = 42) or fructose (45) consumption; *P < 0.01. (F) Plasma adropin levels at baseline were similar for the glucose and fructose groups, but then diverged with the consumption of glucose or fructose as 25% of daily energy requirements. (G) The difference in the effect of glucose or fructose consumption on plasma adropin levels was highly significant. *P < 0.01.
