Frequently Asked Questions (FAQ)

What are adzuki beans?

Adzuki beans (also spelled azuki or aduki) are small, reddish-brown beans native to East Asia. They have a naturally sweet, nutty flavor and are one of the most widely consumed legumes in Japan, China, and Korea, where they are used in everything from soups and rice dishes to sweet pastes and desserts.

How do adzuki beans compare to kidney beans?

Adzuki beans are smaller and sweeter than kidney beans, with a softer texture when cooked. Nutritionally, they are similar in protein and fiber content, but adzuki beans have slightly fewer calories per cup (294 vs. 225 for kidney beans) and a notably sweeter taste that lends itself to dessert applications. Kidney beans, on the other hand, are more commonly used in savory dishes like chili and stews.

What is red bean paste (anko)?

Red bean paste, known as anko in Japanese, is a sweet paste made by boiling adzuki beans and mashing them with sugar. It is one of the most important ingredients in Japanese confections (wagashi) and is used as a filling in mochi, dorayaki, taiyaki, and many other traditional sweets. The two main varieties are tsubuan (chunky) and koshian (smooth).

How much protein and fiber do adzuki beans have?

One cup of cooked adzuki beans provides about 17.3 grams of protein and 16.8 grams of fiber, which is roughly 60% of the daily recommended fiber intake. This combination makes adzuki beans highly satiating and beneficial for digestive health, blood sugar regulation, and muscle maintenance.

Are adzuki beans good for weight loss?

Adzuki beans can be an effective food for weight management because of their high fiber and protein content, which promote fullness and reduce overall calorie intake. They are also very low in fat, with less than 1 gram per cup cooked. Their slow-digesting complex carbohydrates help maintain steady blood sugar levels, reducing cravings between meals.
