Beyond Digestion: Fiber's Role in Cancer Prevention

Story at-a-glance

Fiber byproducts — short-chain fatty acids — physically attach to DNA regions, influencing how genes are turned on or off through epigenetic regulation
A comprehensive review of 11 meta-analyses found that higher fiber consumption correlates with reduced risk of several cancers, including gastric, esophageal, ovarian and endometrial tumors
Fiber helps regulate hormone pathways and curbs inflammation, with studies showing it may reduce estrogen reabsorption, lowering the risk of hormone-related cancers like breast cancer
Research indicates modern diets often lack adequate fiber, leading to chronic metabolic strain and disrupted digestive processes, making fiber optimization an important public health strategy
People with compromised gut health should introduce fiber gradually, starting with easily digestible carbohydrates like white rice and fruit juices before progressing to more fibrous foods. In severe cases, start with dextrose water
