VITAMIN D AGAIN
ANCHOR LEAD: YET ANOTHER LARGE STUDY SHOWS THE BENEFITS OF VITAMIN D IN REDUCING CANCER RISK, ELIZABETH TRACEY REPORTS
Vitamin D supplements do appear to reduce one’s risk of developing cancer of any type, a recent large meta-analysis, where many studies are pooled and examined together, has concluded. Michael Choti, director of surgical oncology at Johns Hopkins, describes the study.
CHOTI: This was a meta-analysis looking at a variety of randomized studies to try to see the correlation between vitamin D consumption and cancer risk. And in this study of many patients, over 50,000 participants, they identified that indeed, vitamin D supplementation seemed to be associated with a decrease in total cancer mortality rate. :22
While such studies are provocative, they suggest another type of study.
CHOTI: The ultimate would be a randomized trial but difficult studies to do because one needs to control the vitamin D consumption in the control groups, as with other vitamin supplement studies it will be a difficult question to prove. :12
When other vitamins have been subject to more rigorous scrutiny in a randomized trial, no benefit was seen. I’m Elizabeth Tracey reporting.
