Minerals

Minerals are essential nutrients that play a crucial role in maintaining various physiological functions in the human body. They contribute to a wide range of biological processes, from building strong bones and teeth to facilitating nerve transmission and muscle contraction. Understanding their importance can help individuals make informed choices about their diet and overall health.Minerals can be divided into two categories: macrominerals and trace minerals.

Macrominerals are required in larger amounts and include calcium, potassium, magnesium, sodium, chloride, and phosphorus. Trace minerals, which are needed in smaller quantities, encompass iron, zinc, copper, manganese, selenium, and iodine. Each mineral has specific functions that are vital for health, and a deficiency in any of them can lead to significant health issues.

Essential Minerals and Their Food Sources

A balanced diet rich in various foods is essential for obtaining the necessary minerals. Below is a list of essential minerals, their functions, and food sources that are high in each mineral.

• Calcium: Vital for bone health and muscle function.
  • Dairy products (milk, yogurt, cheese)
  • Leafy green vegetables (kale, broccoli)
  • Fortified plant-based milks (almond, soy)
• Iron: Essential for oxygen transport in the blood.
  • Red meat (beef, lamb)
