5 Health Benefits of Kuromamecha Black Soybean Tea

Kuromamecha is a nutty, sweet black soybean tea made from roasted black soybeans that offer numerous health benefits. After roasting, the beans can be left in bean form or ground into a powder for tea.

At Senbird, our Kuromamecha Yui is left in bean form, allowing you to eat the delicious beans for extra fiber after brewing. Our Kuromamecha originates from Hokkaido, a prefecture well-known for its superior agricultural practices. The rich soil there contributes to the flavor, aroma, and quality of these round black soybeans. The southwest region of Kyushu is also famous for producing quality black soybeans.

In Japan, Kuromamecha is a particularly popular herbal tea due to its health benefits and versatility. Read on to learn about how incorporating this herbal tea into your diet can be beneficial to your health.

1. Anti-Aging

Black soybeans contain an antioxidant called anthocyanin [1], which gives the soybean its natural dark pigmentation, such as that found in the skin of blueberries and eggplants, two other foods full of healthy vitamins and nutrients. In addition to pigmentation, this antioxidant is thought to improve blood pressure, blood flow and prevents the loss of collagen in the body, all of which contribute to fighting the signs of aging.

2. Disease Prevention

Similar to the health benefits of sobacha buckwheat tea, drinking Kuromamecha black soybean tea does more than just keep you looking and feeling youthful. Anthocyanin is also an anti-inflammatory antioxidant that prevents carcinogens from developing in the body. Drinking this tea can also decrease your chances of developing diabetes and various heart diseases by stabilizing blood sugar levels, lowering cholesterol, and reducing the risk of arteriosclerosis (hardening of the arteries).

3. Weight Loss

Kuromamecha consists of compounds such as isoflavones and saponin that improve your body’s lipid metabolism. Similar to green tea, improving metabolism limits fat absorption and enhances the rate by which fat is burned. Furthermore, black soybeans are legumes, which are naturally high in fiber and regulate digestion as well as blood sugar levels. After brewing, considering eating the softened beans for an additional boost to your daily dose of fiber!

4. Caffeine-Free

Unlike Japanese green teas, such as Sencha or Matcha, Kuromamecha is an herbal tea, which means it contains no caffeine. If you enjoy coffee but are sensitive to caffeine, Kuromamecha could be the perfect non-caffeinated alternative for you. It has an earthy, nutty flavor, which is refreshing without the effects of caffeine. Herbal teas are ideal for those looking to enjoy a cup of tea during the evening hours without the impact of caffeine delaying or disrupting your sleep.

5. Hormone Regulator

For women, drinking Kuromame black soybean tea has an added bonus. The same isoflavones that assist with weight loss can also work as hormone regulators. They work similarly to estrogen within the body, helping with hormonal imbalances like menopause and PMS. In addition, hormone regulation results in healthy and clear-looking skin. Although Kuromamecha is popular in Japan, it is not as well-known elsewhere.

We hope you will consider trying this special and healthy herbal black soybean tea after learning about its incredible health benefits!
