Dietary emulsifiers promote physiological changes consistent with metabolic syndrome. Male and female C57Bl/6 mice were exposed to drinking water containing CMC or P80 (1%) for 12 weeks. (A) There was a main effect of treatment with emulsifiers on fat-pad mass [F(2,29) = 12.48, p < 0.001]. There is also a main effect of sex on adiposity such that males had greater fat mass than did females F(1,29) = 7.65, p < 0.01]. Post-hoc comparisons indicate that both CMC and P80 increased fat mass in females, but in males only CMC treatment increased fat mass compared to respective water-treated controls (*p < 0.05). (B) There was a significant interaction of emulsifier treatment and sex on colon weights [F(2,29) = 3.383, p < 0.05], with post-hoc comparisons indicating that P80 treatment significantly reduced colon weights in female compared to water-treated controls (*p < 0.05). (C) Emulsifier treatment also had a significant main effect on colon lengths in male and female mice [F(2,29) = 28.70, p < 0.0001] such that females treated with both emulsifiers and males treated with P80 had significantly shorter colons compared to their respective water-treated controls (*p < 0.05). (D) There was a significant main effect of both emulsifier consumption [F(2,29) = 5.312, p < 0.05] and sex on spleen weights [F(1,29) = 43.31, p < 0.0001]. Post-hoc comparisons indicate that treatment with both CMC and P80 increased spleen weight compared to water-controls in males, but not females (*p < 0.05). Data are represented as means + SEM (n = 5–6).
