Deleterious Impacts of Western diet on Jejunum Function and Health are Reversible.

The goal of this study was to determine whether the influence of high-fat high-sugar diet (Western diet) on intestinal function and health was reversible. We measured transepithelial short circuit current (Isc), across freshly isolated segments of jejunum from male C57Bl/6J mice randomly assigned to one of the following groups for the study duration: high-fat high-sugar diet for 24-weeks (HFHS), HFHS diet for 12-weeks then switched to standard chow and water for a further 12 weeks (Std), and lean controls (standard chow and water for 24-weeks). At the completion of the study, segments of jejunum were frozen for western blot determination of key proteins involved in secretory and absorptive functions, as well as senescence.

High Fat High Sugar Diet Reduces Small Intestinal Secretion by Sex-Dependent Mechanisms.

Background/aims: The goal of this study was to determine the influence of high-fat high-sugar diet (Western diet) on intestinal function and subsequently to determine if there were any beneficial effects of exercise, genistein (a naturally occurring phytoestrogen) or both, on the intestine.

Methods: We measured transepithelial short circuit current (I), across freshly isolated segments of jejunum from male and female C57Bl/6J mice randomly assigned to one of the following groups for the 12-week study duration: high-fat high-sugar diet (HFS), HFS with genistein (Gen), HFS with exercise (Ex), or HFS with both genistein and exercise (Gen+Ex) and compared them to lean controls. Genistein concentration was 600 mg genistein/kg diet.
