Effects of Palm Olein-Olive Oil Blends on Fat Deposition in Diet-Induced Obese Mice

Current knowledge on the partial replacement of palm olein with olive oil on fat deposition is inadequate, thus leading to our interest to unveil the effects of palm olein on fat deposition by using mouse model. Our findings revealed that the normalized subcutaneous adipose tissues weight, liver weight and body weight gain of mice fed with either palm olein or the blends were remarkably lower than the mice fed with olive oil. The weight of subcutaneous adipose tissues of mice fed with palm olein and blend (PO:OO=50:50) were significantly lower than the mice fed with olive oil. In addition, body weight of the mice in palm olein group were significantly lower than those fed with olive oil group. The results implied that the mice fed with palm olein and palm olein-olive oil blends are less fattening than those fed with olive oil.
