Essential Minerals for Optimal Health

Minerals and elements play a crucial role in maintaining normal body functions and overall health. Among these, water, common salt, and minerals such as calcium, magnesium, iron, sodium, and potassium are indispensable for the body's growth and development. Additionally, chlorine (found in common salt), sulfur, phosphorus, and silicon are vital for various physiological processes.

Unlike other nutrients, minerals consist of single atoms that carry an electric charge when in solution. This unique property allows them to combine with other minerals, forming stable complexes essential for the structure of bones, teeth, cartilage, and other tissues. For instance, calcium and phosphorus work together to form hydroxyapatite, the mineral compound that gives bones and teeth their rigidity.

The Role of Iron
Iron is a critical mineral required for the formation of hemoglobin, the blood pigment that carries oxygen from the lungs to the rest of the body, and myoglobin, the muscle pigment that stores oxygen in muscles. Iron is also a component of various enzymes that facilitate biochemical reactions in the body. Iron absorption begins in the intestinal mucosa cells through the brush border membrane.

A deficiency in iron can lead to anemia, a condition characterized by fatigue, weakness, and decreased immune function. To prevent this, it is recommended that adults consume approximately 10 mg of iron daily. Good dietary sources of iron include liver, animal muscle tissues, eggs, oatmeal, wheat flour, cocoa, and chocolate.

The Importance of Iodine
Iodine is another essential mineral, primarily found in the hormone thyroxine, produced by the thyroid gland. This hormone is crucial for regulating metabolic rates. A deficiency in iodine can result in low metabolic levels, lethargy, and goiter, an enlargement of the thyroid gland. The daily requirement for iodine is about 0.1 mg. Seafood and saltwater fish are excellent sources of iodine.

Iodine deficiency is particularly detrimental to unborn babies and young children, as it can impair brain development, leading to mental retardation or even death. In regions where water lacks sufficient iodine, iodized table salt is used to ensure adequate intake. The World Health Organization recommends that iodized salt contain one molecule of iodine per 100,000 salt molecules. However, in the United States, iodized salt contains a higher concentration, with one iodine molecule per 10,000 salt molecules.

Conclusion
Minerals are vital for numerous bodily functions, from building strong bones and teeth to facilitating oxygen transport and regulating metabolism. Ensuring adequate intake of essential minerals like iron and iodine is crucial for maintaining health and preventing deficiencies that can lead to serious health issues. By consuming a balanced diet rich in these minerals, individuals can support their body's needs and promote overall well-being.

Manifestation of iodine deficiency

Iodine is an essential constituent of the hormones of the thyroid gland, namely, triodothyronine (T3) and thyroxine (T4). These hormones are essential for normal growth and physical and mental development in animals and man.

Iodine deficiency is the result of insufficient dietary iodine intake, which can lead to inadequate production of thyroid hormones and many adverse effects at all life stages, collectively known as iodine deficiency disorders.

The diet is likely to be deficient whenever the soil content of iodine is low, which is often the case in mountainous regions. The most severe deficient soils are those of the European Alps, the Himalayas, the Andes and the vast mountains of China.
WHO recommends that the daily intake of iodine should be 90 μg for preschool children (0 to 59 months), 120 μg for schoolchildren (6 to 12 years, 150 μgfor adults (those older than 12 years) and 200 μg for pregnant and lactating women.

Iodine deficiency leads to inadequate production of thyroid hormone that indispensible for brain growth and development. The iodine deficiency disorders consist of wide spectrum, including mental retardation, impaired physical development, increased prenatal and infant mortality, hypothyroidism, cretinism and goiter.

The most visible manifestation of iodine deficiency is goiter. Goiter is defined as an enlargement of the thyroid gland and cretinism is a term used for a severe form of iodine deficiency characterized by severe mental retardation. Thyroid function is dependent upon the availability of iodine and several other trace elements, The relationship between the iodine intake level of a population and the occurrence of thyroid disease is U-shaped, with an increase in risk associated with both low and high iodine intake.

Iodine deficiency during pregnancy remains a common cause of preventable cognitive of impairment worldwide. The most severe damage due to iodine deficiency occurs from the fetal period to the third month after birth, during which iodine deficiency can produce cretinism, an irreversible form of mental retardation.

Iodine deficiency disorders

Iodine deficiency disorders (IDD) are the most important single preventable cause of brain damage and mental retardation worldwide.

It is estimated to affect more than 700 million people, most of them located in the less developed countries.

An iodine deficiency can lead to simple goiter – enlargement of the thyroid gland, and can impair fetal development, causing cretinism.

Cretinism affects approximately 6 million people worldwide and can be averted by the early diagnosis and treatment of maternal iodine deficiency.

Iodine, named after the Greek word for violet, was first observed as a violet vapor during the making of gunpowder at the beginning of the century.

The term iodine deficiency disorders refer to all the ill-effects of iodine deficiency in a population that can be prevented by ensuing that the population has an adequate intake of iodine.

Universal salt iodization (USI) is the main intervention strategy for iodine deficiency control, and was adopted by the International; Conference on Nutrition in 1992, reaffirmed by the World Health Assembly in 1993.

Iron and Iodine in Human Body

A number of minerals or elements are required for normal body functions. Human need minerals to satay healthy. People get minerals by drinking water and eating food.

Minerals play significant roles in virtually every metabolic process occurring within the body.

Iron is required, since it is an essential part of both the blood pigment, hemoglobin, and muscle pigment, myoglobin.

Some body enzymes also have composites that include iron. Deficiencies of iron cause anemia. It is the most common nutrient deficiency, affecting more than 1.2 billion people.

Liver, animal muscle tissues, eggs, oats meal, wheat flour, cocoa, and chocolate are good source of iron. Approximately 10.0 mg of iron are required daily.

For many people that meal is breakfast, which may also include citrus juice whose vitamin C may increase the absorption of nonheme iron.

Iodine is required by all vertebra animals, including the human, since it is a component of the hormone, thyroxine, produced by the thyroid gland.

Thyroid hormone is constructed from iodide and the amino acid tyrosine and has two form thyroxine (T4) and triiodothyronine (T3) based on the number of iodide atoms.

This hormone regulates metabolic levels. Deficiency of iodine leads to low level metabolism, lethargy, and goiter. Iodine deficiency has existed for centuries.

Requirements of iodine are believed to be about 0.1 mg daily. In food iodine is mostly in its ion form – iodide. Sea food and salt water fish are the beat sources of iodine. In areas where the water is known to be deficient in iodine, iodized table salt may be used in place of regular table salt.

Iodine in human nutrition

The only physiological role known for iodine in the human body is in the synthesis of thyroid hormones by the thyroid gland.



The hormone is thyroxin. Thyroxin controls everything from how often the heart beats to the body’s metabolism.



Iodine from the diet is absorb throughout the gastrointestinal tract. Dietary iodine is converted into the iodide ion before it is absorbed.



The iodide is used by the thyroid gland for synthesis of thyroid hormones and the kidneys excretes excess iodine with urine.



People need to eat iodine containing food regularly, however, because only the amount needed by the thyroid gland to make sufficient amounts of thyroxin is absorbed by the body at any one time, excess iodine is not stored.



In the absence of sufficient iodine the gland attempts to compensate for the deficiency by increasing its secretary activity, and this cause the gland to enlarge. This condition is known as goiter.



Iodide found in seafood; however, large differences in iodide content exist between seawater fish and freshwater fish. Other protein rich foods also supply iodide including milk, yoghurt, egg and meat.



An additional source of iodide is breads and grain products made from bread dough.
