Vitamin D linked to lower colorectal cancer risk in younger adults. A new study suggests that increasing vitamin D intake may protect younger adults against colorectal cancer.
A study has discovered an association between a higher total intake of vitamin D and a lower risk of colorectal cancer in adults under 50 years of age.
According to the estimates, by 2030 almost 11% of colon cancers and 23% of rectal cancers will affect adults under 50 years of age.
Researchers have already found a link between early-onset colorectal cancer and obesity and sedentary lifestyles.
They suggest that reduced consumption of foods rich in vitamin D, such as dairy products, fish, mushrooms, and eggs could increase the risk of developing colorectal cancer.
The latest study investigated the known risks, such as smoking, drinking alcohol, red meat consumption, and sedentary behaviours. Their findings show that total vitamin D intake was significantly associated with a reduced risk of early-onset colorectal cancer.
The study results now appear in the journal Gastroenterology.
They indicate a strong association between vitamin D intake from dairy sources and reduced risk of colorectal cancer.
“Observational studies such as this one shed some light on the role of diet and specific factors like vitamin D toward the increased incidence of young-onset colorectal cancer, but more research is necessary to draw conclusions,” Manju George, M.V.Sc., Ph.D., medical affairs consultant at the Colorectal Cancer Alliance, said.
The researchers also said that dietary vitamin D seems to be more effective than vitamin D from supplements.
