Vitamins & Minerals

Nutrients are grouped into two major classes, macronutrients and micronutrients. Macronutrients are nutrients that are needed by the body in large amounts while micronutrients are those needed by the body in minute amounts.


Vitamins & Minerals

Macronutrients such as carbohydrates, proteins, and lipids provide molecules for the structural and metabolic activities of the human body, while micronutrients (vitamins and minerals) are essential for the body’s proper functioning. The need for micronutrients depends on the metabolic activities as well as on the life cycle of an individual. Even in intrauterine life, the need for micronutrients is essential for the normal development of the fetus. In particular, vitamin D, iodine, iron, and folic acid deficiencies could lead to congenital disorders or even death. The daily requirements of these micronutrients are not fixed, although many scientific papers have mentioned the daily-required allowance of various vitamins and minerals. Factors such as physical exercise, pregnancy, childhood, adolescence, old age, or specific diets (e.g. Vegan) influence the need for micronutrients. Therefore, the evaluation of the micronutrients’ requirements and the consequences of micronutrients deficiencies are critical to explaining their role in health and disease.


Fortification of food is one of the most effective and safe strategies used to enhance nourishment. For example, mother milk feeding can be considered a type of fortification, which is essential for the healthy growth of babies up to 2 years of age. Micronutrients play an important role in the reduction in the risk of disease and the maintenance of good health. Micronutrients and vitamins are vital for the proper functioning and proliferation of all dividing cells in the body. Therefore, micronutrients are essential for growth and metabolism. Balanced diet aids in maintaining good health by increasing the body’s resistance to infection and, in the case of disease, can be a useful component of the therapy. Nutrients provide basic molecules which humans are unable to synthesize. Vitamins and minerals are required in small quantities (<100 mg/day) and are known as micronutrients. The two important classes of micronutrients.


Kinds of Macros

Micronutrients can be divided into four categories:

- water-soluble vitamins,

- fat-soluble vitamins,

- microminerals,

- and trace minerals.

Minerals and associated body functions

  • Calcium (Ca) Bones and teeth

  • Magnesium (Mg) Bones, energy metabolism

  • Phosphorus (P) Bones, teeth, energy metabolism, genes

  • Potassium (K) Nerve and muscle activity, blood pressure

  • Chromium (Cr) Metabolizing starches and fat, insulin activity

  • Copper (Cu) Energy metabolism, blood formation

  • Fluoride (Fluorine, F) Teeth and bones

  • Iodine (I) Thyroid function

  • Iron (Fe) Blood production

  • Selenium (Se) Antioxidant

  • Zinc (Zn) Gene expression, immune function

Conclusion

Vitamins and minerals are essential substances for the normal functioning and development of the body. There are two classes of vitamins namely: Fat-soluble and Water-soluble vitamins.


A number of minerals are essential for health. The essential minerals of the body are divided into two, macrominerals and trace minerals. The trace minerals are those that are required in small amounts by the body but do not imply they have little significance to the body. Micronutrients satisfy both the qualitative and quantitative requirements in the human diet and are consumed in moderate amounts.
