From which food sources is calcium primarily obtained?

Calcium is essential for various bodily functions, particularly for maintaining strong bones and teeth, as well as aiding in muscle function and nerve signaling. The primary sources of calcium in the diet are dairy products and certain fortified foods. Milk is one of the most well-known and widely consumed calcium-rich foods. Fortified orange juice, which has calcium added to it, serves as a great alternative for those who may be lactose intolerant or prefer non-dairy options. Both of these sources provide a significant amount of calcium, making them the primary dietary sources for most individuals.

While other options include foods that do contain some calcium, they do not provide the same level of calcium concentration as milk and fortified orange juice. For instance, while sardines and almonds do offer calcium, they are not typically consumed in large quantities compared to milk and fortified beverages. Understanding these distinctions helps highlight why milk and fortified orange juice are the best answers regarding primary calcium sources.
