Black soybeans (“kuromame”) are referred to as the “Crown Prince of Beans” because they contain a variety of antioxidants and health benefits. Kuromame have been used in Chinese medicines for ages to help clear toxins from the body and have been linked to effective weight loss.

With obesity threatening more than one-third of American adults, health enthusiasts in the West are actively looking into the weight loss benefits of the black bean tea. According to an article published in the Journal of Obesity, black soybeans show promise in treating obesity.

Of course, no single supplement or food can help you achieve your weight loss goals until you make changes in your lifestyle, including your food intake and exercise habits. However, a growing body of research demonstrates how black soybeans contain certain compounds that can aid in maintaining a healthy weight.

Let’s further dive into these compounds, their properties, and how they promote weight loss:

Polyphenols in black bean tea

Black soybeans are known to be rich in polyphenols called anthocyanin.

Studies on Anthocyanin have shown its promise is helping offset the weight gained from a high-fat diet. It limits fat absorption in the body by increasing lipid metabolism.

Anthocyanin is also known to fight human diseases.It has anti-aging properties and has shown positive results in lowering cholesterol.

High in Fiber

An important component that makes Kuromame tea a great choice for weight loss and healthier diet is fiber. Foods that are high in fiber—such as black soybeans—reduce appetite, increase a sense of fullness, and lower overall calorie intake. Research has shown that high fiber intake can also help prevent obesity.
