Calcium is one of the most essential minerals in our body. It plays a critical role in transmitting nerve impulses, regulating muscle contraction, and building and maintaining strong bones and teeth. However, there seems to be a lot of misconception around what color calcium is. In this article, we will be demystifying this myth and providing you with several interesting facts about calcium that you might not know.
The Origin of the Myth
There is a common misconception that calcium is white. This myth stems from the fact that most calcium supplements and dairy products like milk, cheese, and yogurt appear to be white. However, this is not a true representation of the color of calcium.
The Real Color of Calcium
Calcium is actually a silver-grey color that appears opaque to the human eye. It is also soft and malleable, which makes it easy to shape and mold into different forms. However, it is rare to come across calcium in its natural form. Most of the calcium that we use is extracted from minerals like limestone, gypsum, and fluorite.
Calcium’s Role in the Human Body
Calcium is vital for our overall health and well-being. It is required in various bodily functions like blood clotting, hormone regulation, and muscle function. In fact, it is the most abundant mineral in the human body, making up approximately 1-2% of our total body weight. The majority of calcium in our body is stored in our bones and teeth, where it plays an important role in maintaining their structure and strength.
The Benefits of Calcium
Calcium is essential for our body to function properly. Here are some of the benefits that calcium provides:
- It promotes healthy bone growth and development.
- It helps prevent osteoporosis and other bone-related diseases.
- It regulates muscle contraction and blood pressure.
- It supports proper nerve function and transmission.
- It assists in blood clotting and wound healing.
Calcium Sources
Calcium is found in a variety of foods, including:
- Milk, cheese, and yogurt
- Leafy greens like spinach and kale
- Sardines and canned salmon (with bones)
- Almonds and other nuts
- Tofu and other soy products
It is important to note that not all calcium sources are created equal. For instance, calcium obtained from dairy products may be easier for the body to absorb than calcium obtained from plant-based sources.
Calcium Supplements
Calcium supplements are a popular way to ensure that your body is getting enough of this essential mineral. However, it is important to talk to your doctor before adding any supplements to your diet. Excessive calcium intake can lead to kidney damage or even heart disease. Therefore, it is essential to follow the recommended dosage and to keep an eye on any potential side effects.
Calcium-Enhanced Foods
Many foods, like orange juice and breakfast cereals, are fortified with calcium. While this is a convenient way to add calcium to your diet, be sure to check the labels to ensure that the added calcium is in a form that is easily absorbed by the body.
