What Are Adzuki Beans?
Adzuki beans (Vigna angularis) are native to China and have been grown in Japan for at least 1000 years. Today, you can find the crops growing in Taiwan, India, New Zealand, Korea, Philippines, and warmer parts of China.
Adzuki or aduki beans are rich in dietary fiber, protein, iron, calcium, and folatei A form of vitamin B that stimulates tissue growth and promotes healthy cell function and red blood cell production. and have strengthening qualities. Also, because of the low glycemic index, adzuki beans are the preferred food for menstruating women and people with diabetes and obesity.
TriviaSo, how do you identify these beans? Let’s find out!
How Do They Look? How Are They Different From Other Legumes?
Adzuki beans are small, oval, bright-red, dry beans. You can find adzuki beans in a deeper red, maroon, black, and sometimes in white colors too.
Unlike other dry bean varieties, such as kidney beans, adzuki beans take very less time to cook, thanks to the small size and fair amount of protein and carbs in them.

Here’s a crisp compilation of what adzuki beans do to you. Go ahead and explore the world of adzuki!
What Are The Benefits Of Adzuki Beans?
1. Help In Weight Loss And Digestion
An unhealthy, high-fat, unbalanced diet is one of the most common and major reasons for obesity. And if obesity is not controlled, it leads to fatal complications.
Adding adzuki beans to your meal improves the lipid metabolism, fat utilization, and energy production and treats obesity the healthy way.
The micronutrients and fiber in these beans can reduce starch metabolism, decreasing glucose levels in your blood and gastric emptying. Due to this, you end up feeling full and satiated and tend not to overeat (1).
2. Promote Kidney Health
Adzuki beans boast of high dietary fiber content – about 25 g (in raw beans) per cup. They also contain potent antioxidant phytochemicals like polyphenols and proanthocyanidins in fair amounts.
The combined action of fiber and antioxidants in adzuki beans scavenge reactive and undesirable free radicals and prevent the infiltration of inflammation-causing macrophages (immune system cells) (2).
Consuming the right amount of adzuki beans keeps your kidneys safe, efficient, and free of inflammation, injury, and complete breakdown.
3. Give You Strong Bones And Enhance Muscle Mass
With age, your bones and muscles tend to lose their strength and the power of repair or healing. This loss results in osteoporosis and reduced muscle mass, especially in post-menopausal women.
Cooked adzuki beans or their extracts contain bioactive ingredients like saponins and catechins. These ingredients restore the bone resorption and bone formation balance in people with osteoporosis and protect them from inflammation and total degeneration (3).
A cup of raw adzukis has about 39 g of protein. Nothing can beat the power of protein! Low carb-high protein diets help you lose the flab and build muscle mass. Because your body takes more time and energy to digest protein, and because adzuki beans have a low glycemic index, it’s a good idea to have them for lunch. You’d feel full, light, and energetic (4).
4. Lower Cholesterol And Detoxify The Liver
Drinking adzuki bean juice or soup reduces the serum triglyceride levels, prevents the accumulation of bad cholesterol (LDL), and protects your liver from inflammation or damage.
The proanthocyanidins and polyphenols in adzuki beans inhibit the production of pancreatic enzymes. These enzymes (especially lipases) are responsible for the absorption of lipids in the intestines (5).
Due to the reduced absorption, the levels of triglyceridesi A type of fat that circulates in the bloodstream. The body converts excess calories into it after a meal. and cholesterol are lower in your blood. When there are less lipids and triglyceridesi A type of fat that circulates in the bloodstream. The body converts excess calories into it after a meal. , there’s low peroxidationi A chain reaction that results in oxidative deterioration of lipids or organic fatty acids compounds present in the body. or toxic residues that attack your liver.
Hence, your liver is free from chronic liver diseases such as cirrhosisi A liver disease that inhibits liver function when healthy liver tissues are replaced by scar tissues in the body. , fibrosis, or cancers.
5. Promote Heart Health
The high levels of antioxidant polyphenols, proanthocyanidins, vitamin B, folatei A form of vitamin B that stimulates tissue growth and promotes healthy cell function and red blood cell production. , and potassium make adzuki beans the ideal candidate for a healthy heart.
These bioactive components reduce the free radicals that cause lipid and fatty acid peroxidationi A chain reaction that results in oxidative deterioration of lipids or organic fatty acids compounds present in the body. . They also exhibit anti-hypercholesterolemic effects, i.e., they relax the blood vessels and reduce hypertension.
The combined effect of all these components keeps your heart safe and cardiovascular diseases at bay (6).
6. Good For Women’s Health And Pregnancy
Adzuki beans are reservoirs of folatei A form of vitamin B that stimulates tissue growth and promotes healthy cell function and red blood cell production. (1.2 mg in 200 g) – one of the essential vitamins for women. Especially in pregnant women, folic acid can help prevent NTDs (neural tube defects) (7).
These beans are also rich in iron, manganese, phosphorus, and other micronutrients that help in regulating your menstrual cycle and premenstrual symptoms (PMS).
Legend has it that Japanese women would consume adzuki red bean paste or soup after menstruation to replenish the blood cells. It is possible that the rich iron content in adzuki beans may help prevent anemia (8).
7. May Have Anti-aging Properties
Adzuki beans have a history of traditional use in herbal medicine to combat aging. Boiled adzuki bean juice has been used for its potential to prevent age-related damage caused by stress and external factors (9).
Research has revealed that extracts from these beans, particularly its seed extract, possess potent antioxidant capabilities. It demonstrates its effectiveness in combating skin photoaging induced by UVB radiation. It not only reduces the production of reactive oxygen species (ROS) but also inhibits the secretion of matrix metalloproteinases (MMP)-1 and MMP-3, which contribute to skin aging.
Moreover, it promotes collagen production, making it a promising ingredient in the development of anti-aging cosmetic products (10).
