Clinical trials find calcium / vitamin D may reduce colon cancer risk
Research findings presented at the American Association for Cancer Research meeting, held this year in San Diego, suggest that supplementing with vitamin D and calcium may reduce colon cancer risk, while consuming too much iron might increase it. Veronika Fedirko of Emory University presented her team’s discovery that supplementing colorectal adenoma (polyp) patients with 2 grams calcium, 800 international units of vitamin D, or a combination of the two for six months was associated with an increase of Bax, a protein that controls apoptosis (programmed cell death), compared with placebo group levels. By increasing Bax levels in the colon’s mucosa, a greater number of precancerous cells (such as those that are found in polyps) may self-destruct. The trial found that the greatest increase in the ratio of Bax to Bcl-2 (an apoptosis inhibitor) occurred in the group that received both calcium and vitamin D. Continue Reading |
