Dietary Fiber Reduces Certain Cancers
Several studies, including a major review in 2011, have demonstrated the crucial role dietary fiber plays in reducing the risk of various cancers, particularly colorectal, gastric, and breast cancers. Fiber, especially from whole grains, fruits, and vegetables, is linked to a lower cancer risk by improving gut health, reducing inflammation, and binding potential carcinogens in the digestive tract.
Colorectal Cancer
For colorectal cancer, studies suggest that a higher intake of dietary fiber promotes faster digestion, reducing the time harmful substances are in contact with the colon lining. This helps lower the risk of cancer development. Increased fiber intake from high-fiber foods such as whole grains and vegetables can act as a protective measure.
Gastric Cancer
A meta-analysis revealed that for every additional 10g/day of fiber consumed, the risk of gastric cancer was reduced by 44%. This is largely due to fiber’s ability to enhance digestion, remove waste more efficiently, and bind harmful compounds that could otherwise damage the stomach lining.
Breast Cancer
Dietary fiber has also been associated with a lower risk of breast cancer, particularly in postmenopausal women. Fiber’s ability to help regulate hormones, particularly estrogen, and reduce inflammation may contribute to its protective effects against breast cancer.
Conclusion
The research strongly supports the role of dietary fiber in reducing the risk of several cancers. By improving digestion, regulating hormones, and reducing inflammation, increasing your daily fiber intake through whole grains, fruits, and vegetables can be a powerful tool in cancer prevention.
