  1. What about dairy? I’m not aware of any negative association with mortality directly.

  2. Nor am I, Isaac.

    The authors of the study I reviewed would favor milk as a source of calcium over calcium supplements without Vitamin D. They speculate that calcium supplements (without D) cause a spike in serum calcium level that promotes atherosclerosis and calcium deposition in plaque.
