Mice were weaned at 3 weeks, maintained on a 12 - hour light cycle, and had ad libitum access to water and a standard rodent chow diet (PicoLab Rodent Diet 20, 5053; LabDiet) or a high - fat diet (TD.88137; Harlan Teklad). (jci.org)
The other group received a choice between a cup of plain rodent chow and a cup of chow mixed with mineral oil, which also has no calories. (monell.org)
Typically, rodent chow diets contain only 4 % sucrose and < 0.5 % free fructose with most carbohydrate as both digestible starch and non-digestible Fiber from grain sources (i.e. wheat, corn, soy). (researchdiets.com)
