This study aims at investigating whether the intake of butter blends containing diacylglycerol (DAG) oil may result in reduced fat accumulation, in similarity to DAG oil, and the potential metabolic differences between butter blends and DAG oil. Four experimental diets containing either 10?wt% DAG butter blend (BDAG), triacylglycerol (TAG) butter blend (BTAG), DAG oil (ODAG) or TAG oil (OTAG) were prepared, and each was fed to a group of 8 male Wistar rats. The design of the experiment was a combined balance and feeding experiment. The rats fed the BTAG and ODAG-diets had a significantly higher protein content than rats fed the BDAG and OTAG-diets, and the fat content was significantly lower in rats fed the ODAG-diet as compared to rats fed the OTAG and BDAG-diets. A significantly higher content of ash was observed in rats fed the two TAG diets. The ratio of abdominal fat weight/body weight was significantly higher for rats fed the BDAG-diet than for rats fed the BTAG and ODAG-diets. To conclude, the beneficial effects of DAG oil in reducing body fat accumulation cannot be observed in DAG oil containing butter blends, and the effect of DAG on bone health requires further investigation.
