Animal nutrition studies are valuable because, unlike in human studies, we can know exactly what and how much was consumed. Such studies are especially valuable when assessing the effects of long-term consumption because human long-term studies must rely on self-report, which may not be accurate (1-3). In recent years, study has turned to diet patterns rather than individual diet constituents, with the recognition that multiple nutrients interact to affect health. To study diet patterns in a controlled experiment, dietary constituents must be presented in such a way that the study participants cannot pick and choose among the diet components. Thus, they are typically mixed together in preclinical nutrition experiments, as in this experiment (6).
