Abstract:
This study compared the minerals concentrations of milk (conventional n = 20; organic n = 19) to almond (conventional n = 18; organic n = 7) and oat (conventional n = 19; organic n = 13) plant-based beverages (PBB). Milk contained more Ca, Mg, P, K, I and Zn than PBB and less Na than oat PBB. Minerals concentrations of conventional and organic milk did not differ but conventional PBBs contained more Ca, P and I than organic PBBs due to permitted fortification. Despite fortification in conventional PBBs, Ca and I concentrations were lower than in milk. No differences were found between conventional and organic PBBs in concentrations of minerals that are not fortified, Mg, K and Zn. Replacement of milk with fortified conventional and organic almond and oat PBB, without other dietary changes, could reduce intakes of Ca and I below recommended intakes in some demographics, and increase prevalence of insufficiency for Mg, K, and Zn.

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
