Several
studies conducted on mice revealed that a diet that contains lots of
black soya beans could help control weight, reduces LDL cholesterol
levels and protect against type two diabetes.Several Korean researchers led by Shin Joung Rho at Hanyang University, Seoul, providing a diet high in fat and cholesterol in excessive amounts for 28 days. Some of the rats given supplements of black soybean in different levels and some of the mice not given at all as a control study.
After two weeks, rats who received 10% of energy from black soya beans is only half the weight increase experienced by the control group who did not have black beans.
Mice that received a diet of 10% of black soybeans also have cholesterol levels 25% lower total cholesterol and LDL ('bad fats') 60% lower than the control group. While the levels of HDL cholesterol ("good fats") in the 10% black soybean diet is much higher than the control group.
This study suggests that black soya bean diet can prevent weight gain significantly and help decrease cholesterol levels, thus Rho writing in the Journal of the Science of Food and Agriculture.
However, further research is needed to determine long-term effects of black soybean diet in humans and other studies to compare the benefits of soy in the diet of yellow and black.
Many experts claim that soy protein helps beneficial fatty tissue and liver metabolism. Black soy beans have been frequently used as a component of Asian medicine in the treatment of diabetes and hypertension, reducing inflammation and improving blood circulation, as well as the treatment of hormonal disorders.
In 1999, the U.S. Food and Drug Administration (FDA) issued a permit for food products containing soy protein for labeling and heart health benefits of soy. Permits are issued based on the evidence that soy protein diet low in saturated fat and cholesterol may help reduce the risk of heart disease.
