Black Bean Juice

Why people make this drink

Sometimes the most powerful remedies are the simplest. Black soybeans have been used in Chinese food-therapy for centuries, and they carry a natural mild sweetness that makes this drink genuinely pleasant to sip. In modern nutritional terms, black soybeans are rich in anthocyanins (the pigment that makes them dark), plant-based protein, fibre, and minerals — all things with reasonable scientific backing for cardiovascular support. In traditional food-therapy, black soybeans are associated with nourishing kidney and spleen, supporting healthy vision, calming the spirit, and helping with conditions ranging from high blood pressure and elevated cholesterol to fatigue, fluid retention, and watery eyes in the wind.

What studies say about the key ingredients

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

  • Black soybeans · Randomized controlled trial, 100 participants · 2013
    Systolic blood pressure fell more in the black soy peptide group (-9.69 mm Hg) than in the placebo group (-2.91 mm Hg) after baseline adjustment. Plasma malondialdehyde decreased and superoxide dismutase activity increased compared with placebo.Limitation: Used an isolated peptide supplement rather than whole black soybeans, and followed participants for only 8 weeks, so the results may not apply to food intake.PubMed 23924691
