What You'll Learn
Cellulose is a type of insoluble fibre
Cellulose is a type of fibre that is insoluble, meaning it does not dissolve in water and does not change form as it passes through the digestive tract. Humans cannot digest cellulose, but it is still important as a source of fibre in our diets. Fibre helps to keep food moving through the gut and supports regular bowel movements, preventing constipation. Consuming fibre-rich foods can also help to lower the risk of developing diverticular disease, a condition characterised by pockets called diverticula along the colon wall.
Fibre is also important for maintaining a healthy weight. Studies have shown that a diet high in fibre may be linked to a lower body fat composition. Fibre helps to absorb water, improving the excretion process and promoting regular bowel movements. This can be especially beneficial for those experiencing constipation, as it helps to soften stools.
In addition to its role in digestion, cellulose may also provide other health benefits. Studies suggest that a high fibre intake may reduce the risk of developing certain diseases, including gastric cancer and heart disease. Fibre also helps to promote the growth of healthy gut bacteria, which is important for overall health and wellbeing.
The best sources of cellulose include seeds such as hemp and flax, as well as whole grains, carrots, tomatoes, cucumbers, legumes, nuts, and other plant foods. It is recommended that adults consume at least 20 grams of fibre per day, although this may vary depending on calorie intake and individual needs.

It helps food move through the digestive system
Cellulose is a type of insoluble fibre that is not digestible by the human body. It is a structural component of plant foods, found in the cell walls of plants. While it might seem counterintuitive that something your body cannot digest can benefit your health, cellulose has several advantages for your overall health and well-being.
One of the key roles of cellulose in the human body is its ability to help food move through the digestive system efficiently. As an insoluble fibre, cellulose stays intact as it passes through the digestive tract. It does not dissolve in water or change form, allowing it to act as a bulking agent. This means it helps push food through the digestive system, supporting regular bowel movements and preventing constipation.
The presence of cellulose in the diet can also reduce the risk of developing diverticular disease, a condition characterised by the formation of pockets called diverticula along the colon wall. Diverticulitis, an inflammation of these pockets, occurs when they become infected. Studies suggest that a high-fibre diet, including cellulose, may also reduce the risk of other diseases, including gastric cancer and heart disease.
The recommended daily fibre intake for adults is generally 20-25 grams, but this may vary depending on age, gender, calorie intake, and personal needs. It is important to note that getting fibre from whole plant foods is usually preferable to supplements or additives, as these foods also provide other beneficial nutrients and compounds.
In summary, while cellulose itself is not digestible by humans, its inclusion in the diet is essential for promoting healthy digestion and reducing the risk of various health conditions. By aiding the movement of food through the digestive system, cellulose helps prevent constipation and related issues, contributing to overall health and well-being.

Cellulose is found in fruits, vegetables and grains
Cellulose is a type of fibre found in fruits, vegetables, and grains. It is also present in other plant foods, as it is part of a plant's cell walls. This includes tree bark and leaves.
The amount of cellulose varies depending on the food. For example, the cellulose content in vegetables ranges from 1 to 21%, while fruits typically contain between 0.6 and 4.2%. Celery, in particular, is very high in cellulose. The skin of plant foods usually has a higher cellulose content than the flesh.
Although humans cannot digest cellulose, it is still an important part of our diet. This is because it acts as a form of fibre, helping to keep food moving through the gut and aiding the body in eliminating waste.
Cellulose is also used as a food additive and can be found in many processed foods, such as ice cream, shredded cheese, and diet foods. It is added to these products to thicken them or improve their texture.

It can help prevent constipation
Although humans cannot digest cellulose, it is important in our diet as a type of insoluble fibre. Fibre is essential for assisting our digestive system, and cellulose helps to keep food moving through the gut and pushes waste out of the body. This movement of food through the digestive system helps to prevent constipation.
Consuming cellulose-rich foods can help defend against digestive tract diseases, such as constipation. Constipation is a common condition characterised by infrequent bowel movements or difficulty passing stools. It can cause discomfort and impact an individual's quality of life. By increasing the amount of fibre in the diet, individuals can help to soften their stools and improve the excretion process.
Fibre helps to absorb water, which increases the bulk and softness of stools. This is particularly beneficial for those experiencing severe constipation, as it can help to bind water to excretory materials, making it easier to pass stools. For this reason, fibre-rich foods or supplements may be recommended for individuals struggling with constipation.
It is generally recommended that adults consume at least 20 grams of dietary fibre per day. However, it is important to note that the recommended fibre intake may vary depending on factors such as age, gender, calorie intake, and personal needs. For example, men may require slightly more fibre, with suggested intakes ranging from 30 to 35 grams per day.
To ensure adequate cellulose intake, individuals should aim to consume a variety of fruits, vegetables, whole grains, nuts, and seeds. The best sources of cellulose include seeds like hemp and flax, as well as carrots, tomatoes, and cucumbers. By incorporating these foods into the diet, individuals can help prevent constipation and promote overall digestive health.

Consuming cellulose may reduce the risk of developing diverticular disease
Humans cannot digest cellulose, but it is an essential part of our diet as it is a type of fibre. Fibre assists the digestive system by keeping food moving through the gut and pushing waste out of the body. This prevents constipation and reduces the risk of developing diverticular disease. Diverticular disease is a condition characterised by the development of pockets called diverticula along the colon wall. Diverticulitis occurs when these pockets become infected and inflamed.
Insoluble fibres like cellulose do not bind with water or change form in the digestive tract. Instead, they travel through the digestive system unchanged, helping to move waste through the digestive tract. Soluble fibres, on the other hand, bind with water and form a gel-like substance, serving different purposes in the body. The Academy of Nutrition and Dietetics recommends an adequate intake of fibre of 14 grams per 1000 calories, or 25 grams for adult women and 38 grams for adult men.
The Western diet, which is high in refined carbohydrates, has been associated with a risk of developing colonic diverticula due to "fibre deficiency". However, there is limited evidence to support this claim, and some studies have even found that a high-fibre diet is associated with a higher prevalence of colonic diverticula. Nevertheless, a high-fibre diet is commonly recommended for patients with symptomatic uncomplicated diverticular disease (SUDD) as it may reduce abdominal symptoms and prevent acute diverticulitis.
Sources of cellulose include seeds like hemp and flax, whole grains, carrots, tomatoes, and cucumbers. Consuming a variety of fruits, vegetables, whole grains, nuts, and seeds ensures adequate cellulose intake, promoting a healthy digestive system and potentially reducing the risk of diverticular disease.
