Vitamin D can prevent early-onset colorectal cancer

According to the first study showing this association, more vitamin D intake (mainly from dietary sources) may help prevent early-onset colorectal cancer or precancerous colon polyps

This research was jointly completed by scientists from the Dana-Farber Cancer Institute, Harvard University School of Public Health and other institutions, and was recently published in the online edition of the journal Gastroenterology

Although the overall incidence of colorectal cancer has been declining, the number of cases among young people is increasing-this is a worrying trend, but it has not yet been explained

"In laboratory studies, vitamin D has the effect of preventing colorectal cancer

The results of this study were calculated to obtain the total vitamin D intake-94,205 women from food sources and supplements participated in the Nurses’ Health Study II (NHS II)

Between 1991 and 2015, researchers recorded 111 cases of early-onset colorectal cancer and 3317 cases of colorectal cancer polyps

Compared with vitamin D supplements, related dietary vitamin D (mainly from dairy products) and vitamin D stronger

Interestingly, the researchers did not find a significant association between total vitamin D intake and the risk of colorectal cancer after the age of 50

In any case, the researchers concluded that a higher total vitamin D intake is associated with a lower risk of early-onset colorectal cancer and precursors (polyps)
