Diet is a key factor for a person living with Type 2 Diabetes, as food containing fibre can provide a range of health benefits to enable better management of their blood glucose.  

Fibre is an important nutrient found mainly in vegetables, fruits, lentils, grains and cereals.   This plays a key role in regulating blood sugar levels helping prevent potentially serious complications that may occur with Type 2 Diabetes.

How Can Fibre Helps Manage Type 2 Diabetes?

Research into Type 2 Diabetes highlights that eating more fibre can improve blood glucose levels (1).  The human body is unable to digest or breakdown fibre; as a result, these plant-based foods do not cause a spike in blood glucose levels the same way other foods may do.

How Fibre Contributes to Weight Loss?

Achieving a healthy weight and maintaining it is an important way to prevent Type 2 Diabetes and other serious health conditions.

Understanding how fibre works in the body to achieve weight loss and maintain a healthy blood glucose level helps people living with Type 2 Diabetes manage their condition. Fibre rich foods stays in the stomach longer causing extended periods of feeling ‘full’ and is also known to be lower in calories which supports weight management.

An Article in the British Medical Journal (BMJ) written by Taylor et al in 2021 summarises the new understanding of type 2 diabetes and discusses how different changes to food intake can achieve the necessary weight loss and maintenance required for remission of Type 2 Diabetes (2).

Types of Fibre   

There are two types of fibre to be aware of and to understand the differences between the two can help to maximise the benefits of this nutrition within the diet.

  • Soluble Fibre

This type of fibre dissolves in water to form a gel-like material. This tends to regulate the speed of digestion, stabilize blood glucose and support absorption of nutrients and is commonly found in oats, peas, beans, apples, citrus fruits, carrots and barley.

  • Insoluble Fibre

This type of fibre does not dissolve in water, it adds bulk to our stools and promotes the movement of food through your digestive system. It is commonly found in whole-wheat flour, wheat bran, nuts, seeds, lentils, beans, some fruit and vegetables such as cauliflower, green beans and potatoes.

Government guidelines published in July 2015 say our dietary fibre intake should increase to 30g a day, as part of a healthy balanced diet (3). Because, currently most adults are only eating an average of about 18g day, we need to find ways of increasing our intake.
