Dietary Supplements: Higher Levels Of Vitamin D Can Reduce Risk Of Colorectal Cancer And Is Vital For Calcium Absorption

 FOUR PACKS HAS MADE MULTIPLE POSTS ABOUT THE NEED TO SUPPLEMENT ONLY A FEW THINGS…CALCIUM, OMEGA-3 RICH FISH OIL, AND VITAMIN D…ALMOST ALL OTHER VITAMINS AND MINERALS COME IN SUFFICIENT AMOUNTS FROM A BALANCED DIET…SUPPLEMENTING ADDITIONAL WHEY PROTEIN IS ALSO VERY RECOMMENED FOR MEN OVER 40 (OGGIES)….

Higher blood levels of vitamin D are associated with a reduced risk of colorectal cancer, according to a large, 1248-case study published today in the British Medical Journal (BMJ). Participants with the highest levels of blood vitamin D concentration had a nearly 40% decrease in colorectal cancer risk compared to those with the lowest levels of vitamin D.

The study, led collaboratively by the International Agency for Research on Cancer (IARC, Lyon, France) and Imperial College of London (London, UK) and funded by the World Cancer Research Fund (WCRF), is the largest ever on the topic, and one of the first on European populations. The results confirm previous findings from smaller studies based mostly on North American populations.

Recent publications have suggested maintenance of blood vitamin D levels at 50 nmol/l or higher for colorectal cancer prevention. Therefore this study also compared low and high levels of blood vitamin D concentration to a mid-level of 50��”75 nmol/l. While levels below the mid-level were associated with increased risk, those above 75 nmol/l were not associated with any additional reduction in colon cancer risk compared to the mid-level.

Dr. Mazda Jenab (IARC), Dr. Elio Riboli (Imperial) and colleagues used data from the European Prospective Investigation into Cancer and Nutrition ( EPIC ), a prospective cohort of over 500 000 Western Europeans, to examine the associations between blood vitamin D concentration and colorectal cancer risk. “Our results support a role for vitamin D in the etiology of colorectal cancer, but this must be balanced with caution regarding the potential toxic effects of too much vitamin D and the fact that very little is known about the association of vitamin D with either increased or reduced risk of other cancers,” said Dr. Jenab.

“There is consistent scientific evidence that low circulating vitamin D concentration is a marker of increased risk for developing colon cancer. However, any public health advocacy for inducing higher circulating vitamin D concentrations by supplementation-as opposed to the average levels that can be achieved with a balanced diet combined with regular, moderate exposure to sunlight-should await clear-cut results from double-blind randomised trials testing whether increases in circulating vitamin D concentration via supplementation can effectively reduce colorectal cancer risk without inducing serious adverse events,” added Dr. Riboli, the coordinator of the EPIC study.
