Low Fibre Diet Increases Colorectal Cancer Risk
A diet low in fibre significantly increases the risk of developing colorectal cancer, according to health experts. The condition, one of the most common cancers worldwide, is strongly influenced by dietary habits. Fibre plays a crucial role in maintaining digestive health by promoting regular bowel movements and reducing the time harmful substances stay in contact with the colon lining.
Beyond cancer, inadequate fibre intake is linked to a host of long-term health issues, including high cholesterol, type 2 diabetes, heart disease, and digestive conditions like diverticulosis. These findings underscore the importance of a balanced diet rich in fruits, vegetables, whole grains, and legumes.
How Fibre Protects the Gut
Dietary fibre, found in plant-based foods, helps regulate digestion and supports a healthy gut microbiome. Soluble fibre dissolves in water to form a gel-like substance that can lower cholesterol and glucose levels, while insoluble fibre adds bulk to stool and prevents constipation. Both types are essential for reducing colorectal cancer risk.
According to the World Health Organization, increasing fibre intake by 10 grams per day can lower colorectal cancer risk by about 10%. Yet many populations consume far less than the recommended 25-30 grams daily.
Expert Recommendations for Prevention
Health experts advise incorporating fibre-rich foods into every meal. Good sources include oats, barley, beans, lentils, apples, berries, broccoli, and nuts. A gradual increase in fibre intake, along with adequate water consumption, helps avoid digestive discomfort.
Dr. Ananya Sharma, a gastroenterologist at Apollo Hospitals, stated: "A low-fibre diet is one of the modifiable risk factors for colorectal cancer. Simple dietary changes can have a profound impact on long-term health." She emphasized the need for public awareness campaigns to promote fibre consumption.
Broader Health Implications
The consequences of low fibre intake extend beyond cancer. Studies show that a fibre-deficient diet contributes to metabolic syndrome, obesity, and systemic inflammation. The Indian Council of Medical Research recommends a daily fibre intake of 40 grams for adults, yet average consumption in India is only about 15 grams.
Policy makers are urged to support nutrition education and make high-fibre foods more accessible. As colorectal cancer rates rise in younger populations, prioritizing fibre-rich diets becomes a public health imperative.
