Fiber (insoluble)

Insoluble fiber is a type of dietary fiber that does not dissolve in water and plays an important role in digestive health by promoting regular bowel movements. Studies have found that insoluble fiber can help reduce the risk of colorectal cancer, with research indicating it may influence gut microbiota and metabolic processes beneficially. Additionally, there is evidence linking higher intake of insoluble fiber to a reduced risk of cardiovascular disease through its effects on cholesterol levels and inflammation reduction. Connections worth noting include its impact on digestive health and its role in reducing the risk of chronic diseases such as colorectal cancer and heart disease. While the evidence supports these benefits, more research is needed to fully understand the mechanisms behind how insoluble fiber affects human health.
