📚 Major vs. Trace Minerals: A High School Food Science Guide
Minerals are essential nutrients that our bodies need to function properly. They're involved in everything from building strong bones to regulating our heartbeat. But did you know that minerals are divided into two main categories: major minerals and trace minerals? The difference lies in the amount our bodies need.
📌 What are Major Minerals?
Major minerals are those that we need in larger quantities – typically more than 100 milligrams per day. They play vital roles in maintaining fluid balance, nerve function, muscle contraction, and bone health.
🔬 What are Trace Minerals?
Trace minerals, on the other hand, are needed in smaller amounts – less than 100 milligrams per day. Don't let the small quantity fool you; they are just as important as major minerals for various enzymatic reactions, hormone production, and immune function.

🔑 Key Takeaways
- ⚖️Quantity Matters: Major minerals are needed in larger quantities compared to trace minerals.
- 🦴Major Roles: Major minerals primarily support structural and regulatory roles like bone health and fluid balance.
- 🧪Enzymatic Power: Trace minerals are crucial for enzyme activity and various metabolic processes.
- 🍎Balanced Diet: Ensuring a varied diet is essential to obtain both major and trace minerals in adequate amounts.
- 💡Supplementation: Consult with a healthcare professional before taking mineral supplements.
