Roughage, also known as dietary fibre, is an essential component of a healthy diet. Fibre is the indigestible part of plant-based foods and is crucial for maintaining digestive health. It can help prevent constipation by adding bulk to stools and facilitating their passage through the digestive tract. There are two types of fibre: soluble fibre, which dissolves in water and can be metabolised by good bacteria in the gut, and insoluble fibre, which does not dissolve in water but adds bulk to stools. A diet rich in fibre is associated with numerous health benefits, including improved digestive health, weight management, and a reduced risk of chronic diseases such as heart disease.

What You'll Learn
Insoluble fibre and constipation relief
Roughage, or fibre, is often recommended to improve digestion and promote gut health. Fibre is usually categorised into two groups based on solubility: insoluble and soluble fibre. Insoluble fibre is what we think of as roughage. This is the material from food that your body cannot break down in digestion, so it remains mostly unchanged as it passes through your body. Insoluble fibre does not absorb water and has a rigid microscopic structure. It adds bulk to stools and helps to move food along the digestive tract.
Insoluble fibre is found in wheat bran, whole grains, most vegetables, legumes, and fruits, such as potatoes and apples, which have soluble fibre in their inner parts and insoluble fibre in their outer skins. It is recommended to eat 14 grams of fibre for every 1,000 calories consumed per day, which is about 25 grams for women and 38 grams for men.
Constipation can be caused by a variety of factors, including poor nutrition, inadequate sleep, limited exercise, emotional stress, and age. It is characterised by less than three bowel movements per week and can be occasional or chronic. Fibre is a major component of foods that relieve constipation. Insoluble fibre helps to relieve constipation by bulking up the stool and speeding up the transit of food through the digestive tract. It acts like a brush, sweeping through the bowels to keep things moving.
If you are experiencing constipation, increasing your fibre intake for a few days by including more high-fibre foods in your diet can help get you back on a more normal bowel movement schedule. However, it is important to do this gradually, as dramatically increasing your fibre intake can cause unwanted side effects like pain, gas, and bloating.

Soluble fibre and stool softening
Roughage, or dietary fibre, is often recommended to improve digestion and has numerous health benefits. Fibre is the indigestible part of plants and carbohydrates. It is usually categorised into two groups based on solubility: insoluble fibre and soluble fibre. Insoluble fibre, found in wheat bran, vegetables, and whole grains, adds bulk to stools and acts like a brush, sweeping through the bowels to keep things moving.
Soluble fibre, on the other hand, is a type of fibre that dissolves in water. When dissolved in the digestive tract, it forms a gel that acts as a natural stool softener, making bowel movements easier and more comfortable to pass. This gel-like consistency helps move stools more smoothly through the digestive tract, improving stool consistency and making it easier to pass. Soluble fibre is found in oat bran, nuts, seeds, beans, lentils, peas, and some fruits and vegetables. Potatoes and apples, for example, have soluble fibre on the inside and insoluble fibre in the outer skin.
A diet rich in fibre is essential for keeping the digestive system healthy. Eating enough fibre can help keep you regular and improve the balance of good bacteria in your gut, reducing the risk of various diseases such as heart disease, obesity, and diabetes. For those with chronic constipation, a non-fermentable soluble fibre supplement may be beneficial. However, excessive fibre intake can lead to bloating and other digestive issues, so it is important to increase fibre intake gradually and ensure proper hydration.
It is recommended that women consume about 25 grams of fibre per day, while men should aim for 30-38 grams. However, only about 5% of people reach these recommended levels. By including more healthy whole grains, legumes, fruits, vegetables, nuts, and seeds in the diet, individuals can boost their fibre intake and reap the health benefits of this essential nutrient.

Roughage and gut health
Roughage, or dietary fibre, is the indigestible part of plant-based foods. It is often recommended to improve digestion and promote gut health. Roughage helps to increase the bulk of stools, prevent constipation, and foster a healthy balance of gut bacteria. It can also aid in controlling blood sugar levels, lowering cholesterol, and assisting in weight management.
There are two types of fibre: soluble and insoluble. Most foods that provide roughage contain a combination of both but are usually richer in one type. Soluble fibre, found in fruits, vegetables, oat bran, barley, flaxseed, legumes, and seeds, absorbs water in the intestine and forms a gel-like substance. This allows gut bacteria to break it down more easily and helps to keep stools soft. In contrast, insoluble fibre has a more rigid structure and does not absorb water. Instead, it adds bulk to stools, helping to move food along the digestive tract.
Fibre is essential for a healthy diet, and most people do not eat enough of it. The recommended daily intake is about 25 grams for women and 38 grams for men, or 14 grams for every 1,000 calories consumed. Eating a variety of fibre-rich foods, such as whole grains, fruits, vegetables, legumes, nuts, and seeds, is the best way to ensure adequate fibre intake and improve overall health.
However, it is important to note that excessive amounts of fibre can cause gastrointestinal discomfort, constipation, nausea, and bloating. Additionally, some individuals with severe digestive symptoms may be prescribed a low-fibre diet by their doctor. Therefore, it is crucial to listen to your body and consult a healthcare professional if you experience any adverse effects.

Fibre intake and side effects
Fibre, or roughage, is often recommended to improve digestion and promote gut health. It may also help lower cholesterol levels, reduce the risk of heart disease, and manage weight and blood sugar. Fibre is found in plant foods, including whole grains, fruits, vegetables, beans, nuts, and seeds.
While fibre is essential for a healthy diet, excessive fibre consumption can lead to some uncomfortable side effects. Firstly, it is important to note that increasing fibre intake should be done gradually and, ideally, under supervision. This is because a sudden increase in fibre intake can cause an overgrowth of bad bacteria in the gut, which can lead to constipation rather than relieve it.
Other side effects of excessive fibre intake include gastrointestinal discomfort, bloating, abdominal pain, nausea, and diarrhoea. In addition, excessive fibre can lead to nutrient deficiencies, as fibre binds with minerals like calcium, zinc, and iron, reducing their absorption. Dehydration and an increased likelihood of flatulence or even bowel obstruction may also occur.
To avoid these side effects, it is recommended to gradually increase fibre intake and ensure adequate water consumption. The recommended daily fibre intake is about 25 grams for women and 38 grams for men, or 14 grams for every 1,000 calories consumed per day.

High-fibre foods
Fibre has numerous health benefits, including improving digestion, promoting gut health, aiding weight management, and helping to maintain consistent blood sugar levels. It may also help reduce the risk of certain diseases, such as heart disease and colon cancer.
There are two types of fibre: insoluble and soluble. Insoluble fibre does not break down in the digestive system and adds bulk to stools, helping to alleviate constipation. It can be found in plant skins and certain green vegetables, as well as fruits and vegetables in general. On the other hand, soluble fibre forms a gel-like substance when mixed with water, aiding the breakdown of gut bacteria. Good sources of soluble fibre include chia seeds, oats, and certain types of fruits and vegetables.
Some specific examples of high-fibre foods are:
- Chia seeds: 10 grams of fibre per 2-tablespoon serving
- Oats: contain a powerful soluble fibre called beta-glucan, which may help manage blood sugar and cholesterol levels
- Kidney beans: one cup can provide around one-third of your daily fibre needs
- Berries: particularly strawberries, which also contain vitamin C, manganese, and antioxidants
- Avocados: also a good source of healthy fats and other vitamins and minerals
- Pears: a tasty, nutritious option that can satisfy a sweet tooth
- Whole grains: such as wholewheat biscuits, shredded wheat, porridge, wholemeal bread, and brown rice
- Nuts: a small handful of unsalted nuts, such as almonds, can provide around 3.8 grams of fibre
