In evaluating 14 newly diagnosed adult celiac patients who had been on a gluten-free diet (7 consumed the diet plus calcium at 1 gm. per day and vitamin D2 at 32,000I.U. given weekly compared to 7 diet only subjects) for 12 months, gluten restriction increased overall bone mass 5% in the lumbar spine and 5% in the total skeleton. When considering the 11 patients who strictly followed the gluten-restriction, bone density increased 8.4% in the lumbar spine and 7.7% in the total skeleton. The remineralization of patients treated with diet only was similar to that of patients treated with diet and supplements.
