One of the most famous persons in the world presently is Barack Obama. If you don’t know who he is, persons will walk away thinking you are stupid, but may never say it. The same is true of the mineral Calcium. The basic knowledge of it is good for strong teeth and bones is known by most. Dare one say they don’t know this about calcium and they would have earned rightfully the title “world’s most clueless person.” So writing an article on the world’s most popular minerals is hard since it is hard to tell you something you don’t already know.


Well here a few hidden facts about calcium:


a) Almost 99% of the body’s calcium exists in the bones and teeth, the rest is found in the blood stream.


b) Calcium is the 5th most abundant element in the Earth’s crust


c) It is essential for animal and plant nutrition. Calcium participates in many biochemical reactions, including building skeletal systems and moderating muscle action.


d) Vitamin D is essential for calcium absorption by the human body. Vitamin D is converted to a hormone which causes intestinal proteins responsible for calcium absorption to be produced.


e) Although calcium is not usually a toxic mineral, renal failure and other harms to the body have been reported by persons whose calcium intake exceeded that recommended by those in the health profession.


f) Calcium is used for making cement, making cheese, removing non-metallic impurities from alloys, and as a reduction agent in the preparation of other metals


Studies have shown that calcium plays an instrumental role in the regulation of the body’s blood pressure. They also reveal that calcium may also play a role in the prevention of certain types of cancers, including prostate cancer.


So where can we get calcium?


Milk and cheese are the first sources that come to mind, but low fat yogurt tops the list as the richest source of calcium. Sardines, cereal, salmon, tofu and collard greens are also great foods that provide calcium.


The great thing about calcium is that the sources actually taste good. No wonder it is so popular.
