The properties of calcium make it the most important of the minerals linked to the growth, maintenance and reproduction of the human body, and as it does not help to strengthen bones and teeth, keeping them strong and healthy.
Another benefit of calcium is that it helps blood clotting, nerve signals, relaxation and muscle contraction, as well as the release of some hormones; likewise, it is essential for the normal beating of the heart.

As we can see, many are the foods that contain calcium, but mainly and since always calcium has been associated with milk and dairy products, such as yogurt, cheese, and butter.
On many occasions we associate the level of calcium with the fat that the food may contain, but this aphorism is not true at all, since calcium has nothing to do with the proportion of fat that milk, yogurt, butter or other foods high in calcium.
Other foods rich in calcium are vegetables, such as broccoli, collard greens, kale, mustard, or Chinese cabbage.
Sardines, salmon, shellfish, almonds, and dried legumes are also other sources of calcium.
There are some foods prepared for those people who do not usually eat so many dairy products, and that serve as a source of increase of this mineral, are those products such as bread and orange juices that contain a sufficient proportion of calcium for the body.
If there is a certain lack of calcium in the body, people can develop a condition that leads to osteoporosis, hypertension or other disorders.
However, there are other people who are lactose intolerant, that is, it is difficult for them to digest milk sugar and for this reason, different dairy products have been elaborated, which contain calcium that cannot be supplied by said milk or are substituted by others such as rice milk, soy milk, almond milk, which contains the necessary calcium.
