Semi-purified AIN-93G diet was used as the base diet which was supplemented with 10% (w/w) FS as described in our previous publications (14 (link), 15 (link)). Control and experimental diets were isocaloric and identical in physiological fuel value. Whole ground yellow FS (Lot# 1012338) was kindly provided by Dr. Jack Carter (North Dakota State University, Fargo, ND). Mice were maintained on control (0% FS) or treatment (10% FS) diets given ad libitum for three weeks prior to XRT and for the entire duration of the experiment, unless otherwise noted in the text.
