You know black beans and you know soybeans. Now meet the black soybean, an Asian diet staple that could be the secret to weight loss, according to a study in the Journal of the Science of Food and Agriculture.
Korean researchers let rats gorge on fatty foods but added various amounts of black soybeans to their diet. After 2 weeks, the rats eating the most beans (10 percent of their calories) had lowered their LDL (“bad”) cholesterol by 60 percent and had gained only half as much weight as the control group.
Researchers think the beans’ protein may block fat absorption in the liver. Next up? Human studies as well as research into whether the more familiar yellow soybeans work the same way. [source: Women's Health]
