Fibre is an essential part of a balanced diet. It is recommended that adults consume 25 to 30 grams of fibre per day, but most fall short of this, with the average fibre intake being around 15 to 20 grams. Fibre is found in plant foods and is essential for digestive health. It can help to prevent constipation, lower cholesterol levels and reduce the risk of heart disease, stroke, type 2 diabetes and certain cancers. To increase fibre intake, it is recommended to eat a variety of fibre-rich foods, including fruits, vegetables, legumes, nuts, whole grains and starchy foods like potatoes.

Fibre reduces the risk of heart disease, stroke, diabetes, and cancer
Fibre is a type of carbohydrate found mainly in fruits, vegetables, whole grains, and legumes. It is essential for a balanced diet and can provide a range of health benefits. Notably, fibre reduces the risk of heart disease, stroke, diabetes, and cancer.
Firstly, fibre reduces the risk of heart disease. This is because fibre prevents the body from absorbing fat and cholesterol, thus lowering triglyceride and cholesterol levels. Fibre-rich diets may also lower the risk of heart attack and stroke by decreasing inflammation and preventing harmful blood clotting.
Fibre also reduces the risk of stroke. Research has shown that increasing total dietary fibre by 7 grams per day can lower the risk of stroke by 7%. This is because fibre helps to control weight and lower cholesterol levels.
In addition, fibre helps to prevent and manage diabetes. Fibre helps with blood sugar control and weight management, which are both crucial factors for people with diabetes or prediabetes. Fibre does not cause a spike in blood sugar levels like other carbohydrates because it is not broken down and absorbed by the body.
Finally, fibre reduces the risk of certain types of cancer. There is strong evidence that fibre has a protective effect against gastric cancer. Fibre intake has also been linked to a reduced risk of colon cancer, rectal cancer, endometrial cancer, and ovarian cancer. The protective effect of fibre on cancer development is supported by several studies.

Fibre is found in wholegrain cereals, fruits, and vegetables
Fibre is a crucial component of a balanced diet, offering a range of health benefits. Found predominantly in wholegrain cereals, fruits, and vegetables, fibre is essential for maintaining a healthy digestive system and lowering the risk of various diseases.
Wholegrain cereals are an excellent source of dietary fibre. Bran flakes, mixed grain cereals, and malted wheat cereals are all examples of wholegrain cereals that provide a substantial amount of fibre. These cereals are beneficial for digestion and heart health. While they may contain added sugar or salt, their fibre content makes them a healthier option than low-fibre cereals. For an even healthier choice, opt for shredded whole wheat, wheat biscuits, or no-added-sugar muesli.
Fruits are another significant source of fibre. Apples, citrus fruits, carrots, and berries are all fibre-rich options. Adding a piece of fruit to your breakfast can not only increase your fibre intake but also make your meal more satisfying. However, when choosing fruit-containing cereals or mueslis, be cautious of added sugars, as they can significantly increase the sugar content of your meal.
Vegetables also play a crucial role in providing fibre. Cauliflower, green beans, and potatoes are excellent sources of insoluble fibre, aiding in digestion and promoting regular bowel movements. Additionally, a high-fibre diet that includes plenty of vegetables may lower the risk of developing hemorrhoids and diverticular disease.
By incorporating a variety of wholegrain cereals, fruits, and vegetables into your diet, you can ensure a sufficient fibre intake. This not only helps with digestion but also provides numerous health benefits, including a reduced risk of diabetes, heart disease, and certain types of cancer.

The recommended daily fibre intake is 25-30 grams
Fibre is a type of carbohydrate that the body cannot digest. It is important for maintaining a healthy digestive system and lowering cholesterol levels. The recommended daily fibre intake is 25 to 30 grams, which can be achieved through consuming a variety of fibre-rich foods.
Fibre is found in plant foods, including fruits, vegetables, legumes, whole grains, and nuts. It is important to consume both soluble and insoluble fibre, as they have different properties and benefits. Soluble fibre, found in oats, fruits, and legumes, absorbs water during digestion, increasing stool bulk and helping with constipation. Insoluble fibre, on the other hand, remains unchanged during digestion, promoting normal intestinal movement.
To increase your fibre intake, consider the following suggestions: choose high-fibre breakfast cereals such as plain wholewheat biscuits or shredded whole grain; opt for wholemeal or granary breads, and wholegrain pasta, bulgur wheat, or brown rice; include potatoes with their skins on; add beans, lentils, or chickpeas to your meals; and have plenty of vegetables.
Additionally, snack on fresh, dried, or canned fruits; include nuts and seeds in your diet; and choose high-fibre snacks like whole-wheat crackers or fruit with natural yoghurt. It is important to note that a high-fibre diet should be accompanied by adequate fluid intake, especially water, to prevent constipation and ensure the effective movement of intestinal contents.
By following these recommendations, you can ensure you are meeting the suggested daily fibre intake of 25 to 30 grams, contributing to a healthy and balanced diet.

Soluble and insoluble fibre have different properties and health benefits
Fibre is an important part of a healthy, balanced diet. Most plants contain both soluble and insoluble fibre, but in varying amounts. Both types of fibre are beneficial for regulating bowel movements, but they have different properties and health benefits.
Soluble fibre dissolves in water and other bodily fluids, forming a gel-like substance as it passes through the body. This gel feeds the good gut bacteria in the colon, which is linked to various health benefits, including some protection against obesity and its related conditions, such as diabetes. Soluble fibre is also recognised for relieving diarrhoea and improving digestion. It is found in oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables.
Insoluble fibre, on the other hand, does not dissolve in fluids. Instead, it absorbs fluids and sticks to other materials to form stool. This process results in softer, bulkier, and more regular stools, making them easier to pass. Insoluble fibre is particularly effective in relieving constipation. It is found in wheat bran, vegetables, whole grains, and cereals like Weetabix.
To get the benefits of both types of fibre, it is important to eat a wide variety of fruits, vegetables, grains, and legumes. For example, a baked jacket potato with the skin on, followed by an apple, provides around 15.7g of fibre. A mixed vegetable curry with boiled wholegrain rice and a lower-fat fruit yoghurt provides around 9.7g of fibre.
It is recommended that adults increase their dietary fibre intake to 30g per day, as most adults currently consume an average of only 20g per day.

High-fibre foods include oats, beans, nuts, and fruits
Fibre is an essential part of a balanced diet, offering a range of health benefits, including lowering blood sugar, managing constipation, and improving heart health. High-fibre foods include oats, beans, nuts, and fruits, and each of these can be incorporated into a diet in several ways.
Oats are a great source of fibre and can be eaten as oatmeal or porridge, or used in baking. Beans, such as kidney beans and chickpeas, are also high in fibre and can be added to salads, curries, and stews. Nuts, including almonds, chia seeds, and peanuts, can be eaten as a snack or used in cooking. Finally, fruits like strawberries, pears, apples, and avocados are not only tasty but also provide a good source of fibre.
When it comes to fruits, it is important to keep the skin on, as this is where most of the fibre is found. For example, the skin of an apple contains both soluble and insoluble fibre, and one medium apple can provide around 3 to 4 grams of fibre. Similarly, half a cup of sliced strawberries contains around 2 grams of fibre. Pears, with their skin, are another excellent source of fibre and can satisfy a sweet tooth.
In addition to these specific foods, there are other high-fibre options to consider, such as legumes, quinoa, popcorn, and even dark chocolate. It is important to balance fibre with other nutrients, and adding fibre gradually to your diet can help prevent gas and bloating if your body is not used to a high-fibre intake.
