Effects of dietary sugars on intestinal glucose and fructose uptake in lactating and virgin rats. A, B) Glucose (A) and fructose (B) uptakes were measured from the jejunum of lactating dams and virgin rats fed a glucose (G), fructose (F), or starch (S) diet for ∼6 wk. C–E) Effects of dietary sugar and lactation were also determined on the mRNA levels of the intestinal apical Na⁺/glucose cotransporter SGLT1 (C), the intestinal apical fructose transporter GLUT5 (D), and the intestinal basolateral glucose and fructose transporter GLUT2 (E). Bars, analyses, and normalization as in Fig. 1.
