Understanding micronutrients, particularly minerals, is essential for maintaining health and ensuring proper bodily functions. The accurate identification of minerals, their functions, recommended intake, deficiency symptoms, and dietary sources helps students and health professionals promote optimal nutrition. This essay discusses the critical minerals, their roles in the body, the importance of their dietary sources, and emphasizes the significance of using credible resources to avoid misinformation, especially in the digital age.

Minerals are inorganic elements vital for numerous physiological processes. They participate in enzyme systems, contribute to the structural components of tissues, and are involved in nerve transmission and muscle contraction. Among the essential minerals are calcium, iron, magnesium, zinc, and potassium. Each has unique functions and dietary sources that are crucial for ensuring adequate intake through properly balanced diets.

Calcium is perhaps the most well-known mineral, primarily recognized for its role in maintaining strong bones and teeth. According to the National Institutes of Health (NIH, 2020), approximately 99% of calcium in the body is stored in bones and teeth, fulfilling structural and protective functions. Calcium also plays a role in blood clotting, muscle contraction, nerve transmission, and secretion of hormones and enzymes. The Recommended Dietary Allowance (RDA) for calcium varies across age groups, with adults generally recommended to consume about 1000 mg daily (NIH, 2020). A deficiency can lead to conditions like osteoporosis, characterized by weakened bones and increased fracture risk (Kumar & Clark, 2017). Dietary sources rich in calcium include dairy products such as milk, cheese, and yogurt; green leafy vegetables like kale and broccoli; and fortified foods such as cereals and plant-based milk alternatives (Liu et al., 2018).

Iron is essential for the formation of hemoglobin, which enables red blood cells to transport oxygen throughout the body — a critical process for cellular respiration and energy production. The World Health Organization (WHO, 2019) reports that iron deficiency anemia is one of the most prevalent nutritional deficiencies worldwide, affecting vulnerable populations like children and pregnant women. The RDA for iron depends on age and sex, but adult women generally require about 18 mg daily, while men need around 8 mg (NIH, 2020). Iron deficiency can cause fatigue, weakness, and impaired cognitive function, whereas excess iron can lead to conditions like hemochromatosis, which damages organs. Dietary sources of iron include lean meats such as beef and poultry, seafood like oysters and clams, and plant sources such as lentils, spinach, and iron-fortified cereals (Hunt, 2014).

Magnesium functions as a cofactor in over 300 enzymatic reactions related to energy production, protein synthesis, and muscle and nerve function. The National Institute of Health (NIH, 2020) states that magnesium also contributes to structural development of bone and the synthesis of DNA and RNA. The RDA for magnesium varies, with adult men needing about 400–420 mg daily and women around 310–320 mg (NIH, 2020). Deficiency may result in muscle cramps, fatigue, irregular heartbeat, and neurological disturbances. Dietary sources include nuts such as almonds and cashews; seeds like pumpkin and sunflower seeds; whole grains like brown rice and oats; and green leafy vegetables such as spinach (Volpe, 2013).

Zinc is essential for immune function, wound healing, DNA synthesis, and cell division. The WHO (2019) emphasizes zinc’s role in supporting immune responses and metabolic processes. The RDA for zinc for adults is approximately 8–11 mg per day. Zinc deficiency can lead to impaired immune function, delayed wound healing, and growth retardation in children. Conversely, excessive zinc intake can cause nausea, vomiting, and interfere with copper absorption. Good dietary sources are meat and shellfish, especially oysters, beef, and crab; plant sources include legumes, seeds, nuts, and whole grains (Hambidge, 2010).

Potassium is vital for maintaining fluid balance, nerve signal transmission, and muscle contractions. The NIH (2020) highlights potassium's critical role in controlling blood pressure and reducing the risk of cardiovascular disease. The recommended intake ranges from 2,500 to 3,000 mg per day for adults. Deficiency, although rare, can lead to muscle weakness, fatigue, irregular heartbeat, and increased blood pressure (Wang et al., 2017). Foods rich in potassium include bananas, oranges, potatoes, spinach, and tomatoes. Proper dietary intake of potassium is associated with better cardiovascular health (Whelton et al., 2018).

In conclusion, maintaining adequate intake of essential minerals through a balanced diet is fundamental for good health. It is crucial to rely on credible sources such as textbooks, government health agencies, and peer-reviewed journals to obtain accurate and updated information about micronutrients. Investigating proper dietary sources helps prevent deficiencies and avoid misinformation propagated by unreliable internet sources, which may contain inaccurate or harmful data. As future health professionals or informed individuals, understanding these fundamentals fosters better dietary planning and health outcomes.
