Roughage is an essential part of a healthy diet, even though it isn’t digested by the body. Found mainly in plant-based foods like fruits, vegetables, whole grains, legumes, and seeds, roughage plays a vital role in keeping our digestive system working properly.
While it may not directly provide nutrients or energy, roughage supports many important functions-from preventing constipation to feeding good gut bacteria. It can also help manage weight, control blood sugar levels, and lower the risk of heart disease.
Keep reading to explore how fibre can benefit your body and why it’s worth making it a regular part of your diet.
Fibre, also known as roughage, is a component of plant-based foods that the human body cannot digest. Although it is consumed, it largely remains unchanged as it moves through the digestive tract. Once it reaches the large intestine, it is either partially broken down by beneficial gut bacteria or exits the body as waste.
There are two main types of fibre, and both play an essential role:
Adding more fibre to your meals can improve digestion. High-fibre foods are also full of important nutrients like vitamins, minerals, and antioxidants. Here is a detailed overview:
