Dietary Intake and Gastrointestinal Integrity in Runners Undertaking High-Intensity Exercise in the Heat

Naroa Etxebarria, Nicole A. Beard, Maree Gleeson, Alice Wallett, Warren A. McDonald, Kate L. Pumpa, and David B. Pyne

for biomarkers, which represent GI permeability, included lipopolysaccharide (LPS), lipopolysaccharide-binding protein, and intestinal fatty-acid-binding protein (i-FABP). All biomarkers were analyzed in duplicate, as previously described ( Wallett et al., 2020 ). Statistical Analysis The descriptive

The Impact of a Short-Term Ketogenic Low-Carbohydrate High-Fat Diet on Biomarkers of Intestinal Epithelial Integrity and Gastrointestinal Symptoms

Alannah K.A. McKay, Alice M. Wallett, Andrew J. McKune, Julien D. Périard, Philo Saunders, Jamie Whitfield, Nicolin Tee, Ida A. Heikura, Megan L.R. Ross, Avish P. Sharma, Ricardo J.S. Costa, and Louise M. Burke

concentrations of intestinal fatty acid-binding protein (I-FABP), lipopolysaccharide-binding protein (LBP), and soluble CD14 (sCD14) were measured in duplicate using commercially available enzyme-linked immunosorbent assay kits (HK406, HK315, and HK320, respectively; Hycult Biotech). The intraassay coefficient

. Immediately after exercise (or the equivalent time-period during the resting trial), participants underwent a 2-h oral glucose tolerance test (OGTT) with dual-stable isotope tracers to assess plasma glucose kinetics. Plasma concentrations of intestinal fatty acid binding protein (I-FABP) were assessed as a
