Macrominerals are minerals that your body needs in large amounts (over 100 milligrams per day). They are essential for various bodily functions, such as:

* Building and maintaining strong bones and teeth

* Regulating fluid balance

* Transmitting nerve impulses

* Contracting muscles

* Supporting energy production

Here are the seven major macrominerals:

1. Calcium: The most abundant mineral in the body, essential for bone health, blood clotting, and muscle function. Good sources include dairy products, leafy green vegetables, and fortified foods.

2. Phosphorus: Plays a crucial role in bone health, energy production, and cell signaling. Good sources include dairy products, meat, fish, and nuts.

3. Magnesium: Involved in over 300 bodily processes, including muscle and nerve function, blood sugar control, and blood pressure regulation. Good sources include leafy green vegetables, nuts, seeds, and whole grains.

4. Sodium: Essential for fluid balance, nerve impulse transmission, and muscle contraction. Found naturally in many foods, but often added as salt.

5. Potassium: Vital for muscle contractions, nerve function, and maintaining blood pressure. Good sources include bananas, potatoes, tomatoes, and beans.

6. Chloride: Works with sodium to regulate fluid balance and maintain blood pressure. Found in table salt and many processed foods.

7. Sulphur: A component of proteins and enzymes, involved in detoxification, collagen production, and cell growth. Good sources include meat, eggs, dairy products, and legumes.

Note: While macrominerals are essential, consuming too much of them can be harmful. It's important to follow a balanced diet that provides the right amounts of each mineral. Consult with a doctor or registered dietitian for personalized advice.
