A medium banana will provide about 10-12% of your daily fibre needs. Soluble and insoluble fibres play an important role in your health. Soluble fibre helps your body control your blood sugar level and get rid of fatty substances such as cholesterol.
Insoluble fibre adds weight and softness to stools, making it easier for you to have regular bowel movements. This helps to keep your gut healthy and safe from harmful bacteria.
