Interesting abstract here, posted by another member: http://www.ncbi.nlm.nih.gov/pubmed/20434855 I'd prefer to read a lengthier portion of the actual report rather than merely the synopsis, but those of you have an interest in this topic: What are you reading here? What conclusions, if any, do you draw from this abstract? How are you reading this? Is the control group zero calcium, with a 2% group and a 4% group? Or are you reading this differently in terms of possibly additional calcium above a base amount?
