The shrubby adzuki bean is cultivated in East Asia and thrives best in subtropical situations. Their pea-sized fruits are also called red soybeans.

For millennia, the Adzukibohne cultivated in Japan, China and Korea. It is closely related to other beans such as the mung bean. More recently, it is also grown in South America, the southern United States, some African countries and New Zealand. In Japan, the adzuki bean is the second most important legume after soybean. Depending on the cultivation intensity, yields of between 4 and 30 dt / ha are achieved.

Most annual plants reach a height of 20 to 90 cm. In the legumes grow about pea-sized, dark red seeds. From the also red kidney beans they differ by their form as well as by a typical white line.

Mainly used are the ripe seeds. The green pods are freshly processed into vegetables and salads. Some of the plants are also used as green fodder and fertilizer.

The dry adzuki beans have a sweetish-nutty flavor and are processed and utilized in various ways: they are stored in canned or dried beans. One part is ground and the flour is processed into soups and pastries, jams, sweets and sweet drinks. In Japan, adzuki beans are used to make a sweet bean paste (Anko). The bean sprouts enter the market as Aduki. Popular desserts are the soup Shiruko and the Yokan sweets made from ground adzuki beans, sugar and agar agar. In China, sweet bean paste is wrapped in flat bread or processed into an adzuki cake with syrup.

Legumes are much more important in Asian cuisine than in Western ones. The Adzukibohne came first as part of the macrobiotic diet in the West. In dried form Adzuki beans are available today in Asian and organic food stores.

In addition, the adzuki bean is used as feed for cockatiels and was also processed in a Japanese shower gel.

Importance for the health

Adzuki beans are more digestible than European kidney beans. With a protein content of 20 to 21 percent, they are among the most protein-rich vegetables and provide the body with all the essential amino acids, vitamins B1 and B2 as well as iron, potassium and calcium. Their fiber promotes digestion, relieves the intestines and helps to lower cholesterol levels. Adzuki beans are also believed to have antioxidant properties. A phytoestrogen should also have preventive effects against breast cancer.

The adzuki bean has great importance in Traditional Chinese Medicine (TCM). Due to its diuretic effect, it is used primarily for kidney and bladder problems, but also for tumors of all kinds, overweight and obstetrics. Since anxiety is associated with the kidney in TCM, the adzuki bean is also known as mutton bean. Another effect is the elimination of heat, which is why you treated with the Adzukibohne inflammation.

Incompatibilities & allergies

Allergic reactions to legumes are common, but may be very variable. While the peanut may cause even the most severe reactions, reactions to beans, lentils and peas - and thus to the adzuki beans - are rare. They occur, if at all, in weak, clinically irrelevant intensities. Interesting in this context is the observation that legume allergies may also be caused by pollen sensitization, especially against grass pollen. The reason for this is the occurrence of allergenic proteins in different species.
