Adzuki beans are a good source of magnesium, potassium, iron, zinc copper, manganese and B vitamins. As a high-potassium, low-sodium food they can help reduce blood pressure and act as a natural diuretic. When combined with grains, beans supply high quality protein, which provides a healthy alternative to meat or other animal protein.

Like most beans, adzuki beans are rich in soluble fibre. This type of fibre provides bulk to the stool and binds to toxins and cholesterol aiding in their elimination from the body.

In Japan adzuki beans are known for their healing properties and are used to support kidney and bladder function. Gillian McKeith is a huge fan of the adzuki bean and refers to it as the ‘weight loss’ bean as it low in calories and fat but high in nutrients.
