Increasing Fibre Intake: A Key Strategy for Managing Diabetes

In recent years, there has been growing awareness of the importance of dietary fibre in maintaining good health, especially for individuals with diabetes. Not only does fibre play a crucial role in keeping our gut healthy, but it also offers a range of benefits, including reducing blood cholesterol levels, lowering the risk of cardiovascular disease, and aiding in weight management. However, despite its significance, many people fail to meet the recommended daily intake of fibre.

The Scientific Advisory Committee on Nutrition (SACN) took a comprehensive look at the role of fibre in promoting health and published new recommendations in July 2015. According to these guidelines, adults aged 16 and above should aim for at least 30g of fibre per day, while younger age groups require slightly less: 25g for 11-16-year-olds, 20g for 5-11-year-olds, and 15g for 2-5-year-olds. Surprisingly, the average adult in the UK consumes only around 19g of fibre daily, falling short of the recommended amount.

What is Dietary Fibre?

Dietary fibre is a type of carbohydrate that is exclusively found in plant-based foods. Unlike other carbs, it is not digested or absorbed by the body. There are two main types of dietary fibre: soluble and insoluble. Both types are essential for maintaining good health, and most plant-based foods contain varying amounts of each.

Soluble Fibre: Foods rich in soluble fibre include oat, oat bran, linseeds, barley, fruits, vegetables, nuts, beans, pulses, soya, and lentils.

Insoluble Fibre: Good sources of insoluble fibre are wholemeal bread, bran, wholegrain cereals, nuts, seeds, and the skin of some fruits and vegetables.

The Role of Fibre in Diabetes Management

For individuals with diabetes, increasing fibre intake can prove highly beneficial. The risk of cardiovascular disease is elevated in people with diabetes, and studies have shown that a higher fibre intake, particularly from cereals and wholegrains, can help mitigate this risk. Additionally, evidence suggests that a diet rich in oat bran leads to lower cholesterol levels and reduced blood pressure.

Dietary fibre absorbs fluids and increases the bulk of waste matter, making stools softer and easier to pass, thus promoting digestive health. Moreover, foods rich in soluble fibre have been found to play a specific role in reducing blood cholesterol levels. For those aiming to manage their weight, fibre-rich foods are filling and generally have a lower glycemic index (GI), helping control appetite and stabilizing blood glucose levels.

Tips for Increasing Daily Fibre Intake

To meet the SACN guidelines for daily fibre intake, individuals should strive to consume at least five portions of fruits and vegetables daily. Additionally, meals should be based around starchy carbohydrates, with a preference for wholegrain varieties. Incorporating high-fibre snacks can also help reach the target:

1. Plain oat cakes

2. Fruits

3. Nuts

4. Dried fruit

5. Yogurt with berries and pumpkin seeds

Portion control is crucial, especially for those watching their weight. Adding salads or extra vegetables to meals is another effective way to boost fibre intake.

Fibre for Children

Instilling healthy habits in children is essential for their long-term well-being. Parents can help their children increase their fibre intake in various ways, such as:

1. Offering fruits or small portions of dried fruit as snacks.

2. Introducing wholewheat pasta gradually and mixing it with white pasta initially.

3. Choosing wholegrain cereals for breakfast or adding high-fibre, bran-based cereals to their favorite choices.

4. Preparing smoothies with milk and frozen berries or offering frozen yogurt with berries as a sweet treat.

Smart Shopping for Fibre

Reading nutritional labels on pre-packaged foods can help identify those with higher fibre content. Foods with the terms 'wholemeal,' 'wholewheat,' and 'wholegrain' typically have more fibre and a lower GI, making them a better choice for those managing diabetes. Other shopping tips include:

• Opting for wholemeal, seeded, or multi-grain bread instead of white varieties.

• Choosing brown/wholewheat pasta or rice over white versions.

• Incorporating beans, pulses, and lentils in casseroles, soups, salads, and curries.

• Selecting oat-based, bran, or wholegrain breakfast cereals.

• Including a variety of interesting and seasonal fruits and vegetables to meet the five-a-day target.

• Exploring wholegrains like couscous and quinoa, which are excellent sources of fibre.

Aiming for 30g of fibre per day may initially seem challenging, but gradual increases over time can help individuals reach the recommended target. It's crucial to consult with a healthcare professional before making significant dietary changes, especially for those managing diabetes.

In conclusion, increasing dietary fibre offers numerous health benefits, particularly for individuals with diabetes. By incorporating fibre-rich foods into their diet, people can manage their condition more effectively, promote better heart health, and support overall well-being. Simple changes, such as consuming more fruits and vegetables, wholegrains, and fibre-rich snacks, can make a significant difference in achieving a healthier lifestyle.
