(Ivanhoe Newswire) -- The next time you go to the grocery store, you might want to stock up on black soybeans. Apparently, the darker variety of the legumes has even more health benefits than yellow soybeans.
A new study from Korea reveals a diet rich in black soybeans could help control weight, prevent diabetes, and lower fat and cholesterol levels.

Researchers let 32 rats pig out on black soybeans and fatty foods. After two weeks, the rats getting 10 percent of their energy from black soy gained half as much weight as rat not getting any black soy in their diets. The total cholesterol also dropped by 25 percent, and LDL cholesterol fell by 60 percent in the black soy group.
Experts say soy protein may have an effect on fat metabolism in the liver and fatty tissue, keeping new fatty acids and cholesterol from forming together. This metabolic effect may explain the traditional Asian use of black soy to treat diabetes.
"The key problem in type 2 diabetes is impairment of insulin action, mainly as a result of excess abdominal adipose tissue, so loss of weight often improves glycemic control," reports David Bender, M.D., from University College Medical School in London.
