The protein, calcium, and phosphorus content of vegetarian and non-vegetarian diets differ substantially. It has been suggested in early studies that these differences could lead to differences in bone mineral mass. However, a recent study of 200 lacto-ovo-vegetarians had lower bone mineral mass than their omnivorous counterparts. In both groups, milk was the most common source of calcium, so no conclusion can be drawn from calcium consumption. The possibility of higher sulfur content in the meat-containing diet, the effect of excess phosphorus, and the effect of an acid-ash diet could be contributing factors, though further study is required.
