(VTC News) – Roasted black bean water is a popular traditional drink in Vietnam. But what exactly does it do for your health?
According to Dr. Vu Duy Thanh (as cited by Health & Life Newspaper), in traditional Eastern medicine, black beans have a sweet flavor and are neutral or slightly cold in nature. When roasted, their cold property decreases, becoming warmer and easier to digest. Black beans are said to benefit the spleen, kidneys, and liver—supporting overall balance and vitality.
Roasting the beans before boiling enhances the aroma and helps maximize their health benefits.
Here are the key benefits of drinking roasted black bean water:
Kidney nourishment and vitality support: In Eastern medicine, the kidneys are considered the foundation of vitality and longevity. The black color of the beans corresponds to the Water element, which governs the kidney system. Drinking roasted black bean water helps nourish kidney yin, strengthen bones and tendons, reduce back and knee pain, and may help prevent premature graying of hair and symptoms like dizziness or ringing in the ears caused by kidney deficiency.
Improves digestion and reduces water retention: Weak digestion or “spleen deficiency” can cause bloating, indigestion, and a heavy feeling in the body. Roasted black bean water supports digestion, acts as a mild diuretic, and helps the body eliminate excess fluids—reducing swelling and promoting comfort.
Liver nourishment and better vision: The liver in traditional medicine stores blood and regulates its flow. When the liver is healthy, eyesight improves and muscles remain flexible. Roasted black bean water helps nourish and circulate blood, which can improve vision and relieve symptoms like dry or tired eyes.
Detoxification and body cooling: Even after roasting, black bean water retains mild cooling properties that help detoxify the body, reduce heat-related skin issues such as acne and rashes, and maintain internal balance.
Improves blood circulation: The drink promotes blood flow, helping relieve muscle and joint pain caused by poor circulation or blood stagnation.
Enhances beauty and hair health: Black beans are rich in antioxidants and vitamins that slow down aging, promote healthy skin, and may help darken hair naturally.
Supports safe weight management: The fiber in black beans helps you feel full longer, reducing cravings and supporting gradual, safe weight loss.
Roasted black bean water is therefore considered a wholesome, natural drink beneficial for general health and beauty.
However, there are important precautions to note:
Avoid drinking it when you have a cold or flu, as black beans are still mildly cooling and may worsen chills or cause digestive upset.
Do not drink it if you have weak digestion or frequent diarrhea.
Do not use black bean water as a full substitute for plain water; excessive intake can interfere with nutrient absorption.
Avoid drinking it together with medication, as it can reduce drug effectiveness or cause side effects.
Do not combine it with supplements containing calcium, zinc, or iron, since the phytates in black beans can hinder mineral absorption.
In moderation, roasted black bean water can be an excellent addition to a balanced diet—supporting detoxification, digestion, and long-term vitality.
