Calcium
Definition
Calcium is a mineral essential for building and maintaining strong bones, and it plays a crucial role in heart function, muscles, and nerve signaling.
Scientific / Technical Definition
Calcium is a chemical element with the symbol Ca and atomic number 20. It is the most abundant metal and the fifth-most abundant element in the human body. Calcium ions play a critical role in a variety of cellular processes such as muscle contraction, neurotransmitter release, and blood clotting. It is also a vital component of skeletal tissue, forming calcium phosphate crystals to enhance bone rigidity and strength.
Benefits
- Supports strong bones and teeth
- Aids in muscle contraction and relaxation
- Facilitates nerve signal transmission
- Helps with blood clotting processes
- Contributes to hormone secretion and enzyme activation
Examples
- Milk and dairy products
- Leafy green vegetables like kale and spinach
- Fortified plant-based drinks such as almond or soy milk
- Sardines and salmon with bones
- Tofu and other soy products
Additional Information
- Importance: Calcium is important for maintaining bone health and preventing osteoporosis, a condition characterized by brittle and weak bones. Adequate calcium intake is crucial during childhood and adolescence when bone mass is being built, as well as during older age to minimize bone loss.
