Minerals are essential for normal body functions and overall health. They are obtained through drinking water and consuming a balanced diet. Minerals play significant roles in virtually every metabolic process within the body, ensuring that various physiological systems operate efficiently.
Iron is a crucial mineral required for the production of hemoglobin in blood and myoglobin in muscles, which are essential for oxygen transport and storage. Additionally, several enzymes involved in metabolic processes contain iron. Iron deficiency leads to anemia, the most prevalent nutritional deficiency globally, affecting over 1.2 billion people. Symptoms of iron deficiency anemia include fatigue, weakness, and impaired cognitive function. To prevent anemia, individuals need approximately 10.0 mg of iron daily, which can be sourced from liver, muscle tissues, eggs, oatmeal, wheat flour, cocoa, and chocolate. Including vitamin C-rich foods, such as citrus juices, in meals can enhance the absorption of nonheme iron from plant-based sources, making breakfast an ideal opportunity to boost iron intake.
Iodine is another vital mineral necessary for the production of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). These hormones, synthesized from iodide and the amino acid tyrosine, regulate metabolic rates and overall energy expenditure. Iodine deficiency can lead to hypothyroidism, characterized by low metabolic levels, lethargy, and goiter—a visible enlargement of the thyroid gland. This deficiency has been a concern for centuries, particularly in regions where soil and water lack sufficient iodine. The daily iodine requirement is about 0.1 mg, typically met through the consumption of iodide-rich foods like seafood and saltwater fish. In areas where natural iodine sources are scarce, iodized salt is a common preventive measure to ensure adequate intake.
In conclusion, minerals such as iron and iodine are indispensable for maintaining health and metabolic balance. Iron supports oxygen transport and enzymatic functions, while iodine is critical for thyroid hormone production and metabolic regulation. Ensuring adequate intake of these minerals through diet and supplementation when necessary is key to preventing deficiencies and associated health issues. By incorporating iron-rich and iodine-rich foods into daily meals, individuals can support their body's essential functions and overall well-being.

Food science is the study of food's composition, properties, and interactions with biological and chemical processes. It explores how food is processed, preserved, and safely consumed. By combining biology, chemistry, and nutrition, food science improves food quality, enhances flavor, and ensures safety for global consumption.
