Which type of mineral does the body need in amounts of 100 milligrams or more per day?

The correct answer is major mineral, which refers to minerals that the body requires in larger quantities, specifically 100 milligrams or more per day. Major minerals play crucial roles in various physiological functions, including bone health, fluid balance, and transmission of nerve impulses. Common examples of major minerals include calcium, potassium, sodium, and magnesium.

Understanding the classification of minerals is essential in nutrition. Major minerals are distinct from trace minerals, which the body only needs in smaller amounts (less than 100 milligrams per day). While all minerals are essential for health, the distinction between major and trace minerals is based on the quantity required by the body. Essential minerals encompass both major and trace minerals, but the term alone does not specify the required daily intake amount. Therefore, "major mineral" specifically addresses those essential nutrients needed in larger quantities.
