Final answer:
Trace minerals are essential minerals that are needed in small amounts by the body. Each trace mineral has a specific role in bodily functions. Good dietary sources include a variety of whole foods.
Step-by-step explanation:
Trace minerals, also known as trace elements, are essential minerals that are needed in small amounts by the body. Although they are required in lower quantities, they are no less important than major minerals. Each trace mineral plays a vital role in various bodily functions. Examples of trace minerals include iron, zinc, copper, selenium, manganese, and iodine.
Iron is necessary for the formation of red blood cells and the transport of oxygen throughout the body. Zinc is involved in immune function, wound healing, and DNA synthesis. Copper is needed for the production of red blood cells and collagen, a key component of connective tissues. Selenium is an antioxidant that helps protect cells from damage. Manganese assists in bone formation and carbohydrate metabolism. Iodine is necessary for the production of thyroid hormones, which regulate the body's metabolism.
Good dietary sources of trace minerals include whole grains, seafood, fruits, vegetables, nuts, and legumes. It is important to consume a balanced diet to ensure an adequate intake of these essential minerals.
