Resumen
Colorectal cancer (CRC) is increasing in low- and middle-income countries, likely due to changing lifestyle habits, including diet. We found that a higher total choline intake was associated with an elevated risk of CRC, as well as glycerophosphocholine (GPC) and sphingomyelin (SM). Conversely, betaine intake was associated with a decreased risk of CRC. Consequently, it is possible to focus on the intake of betaine sources and manage the use of animal products as references for SM or other choline types with risks of CRC.
