Colorectal cancer (CRC), one of the most common
cancers worldwide, continues to increase in
incidence and
mortality rates. This trend is closely linked to changes in
dietary habits, which are major
risk factors for
colorectal cancer. The increase in the
incidence of CRC in countries previously considered low-
risk and with
low socioeconomic status is most likely due to
lifestyle and dietary changes.
Understanding the influence of dietary factors on the onset of
colorectal cancer is essential for prevention and
treatment. This
review explores the complex interplay between dietary factors and
colorectal cancer, focusing on the key
nutrients and
dietary habits that influence
disease onset and progression. The impact of
diet on colorectal
microbiota and the influence of
diet on early-onset
colorectal cancer are also reviewed, reviewing recent
research on how dietary interventions
affect the
treatment and
recurrence of
colorectal cancer. Finally, the
future research directions for developing and applying effective dietary intervention
strategies are discussed.
