Nutrition, Health and Well-being

NUTRITION, HEALTH AND WELL-BEING

Nutrition is the process by which living organisms obtain and utilize food materials for growth, repair, and maintenance of health. In children, nutrition plays a critical role as it directly influences their physical and mental development. The diet consists of various foods that provide essential nutrients such as carbohydrates, proteins, fats, vitamins, and minerals. Nutrition is often described as 'food at work' because it involves the digestion, absorption, and metabolism of nutrients to support bodily functions. Children have unique nutritional needs that vary with their stage of growth, body weight, and the efficiency of nutrient utilization. Rapid physical and mental development during childhood makes adequate nutrition vital to prevent lifelong impairments and disabilities. Good nutrition not only supports the growth of organs and systems but also enhances cognitive performance, boosts immunity, increases energy levels, and fosters a positive attitude. Therefore, balancing food intake from all food groups with variety is essential to ensure overall well-being in children.

• Nutrition is the process of obtaining and metabolizing nutrients for growth and repair.
• Children's nutritional needs depend on growth rate, body weight, and nutrient utilization.
• Adequate nutrition prevents lifelong impairments and supports full potential growth.
• Good nutrition enhances organ function, cognitive ability, immunity, and energy.
• Balanced meals with variety from all food groups are essential for child well-being.
• 📌 Nutrition: The process of obtaining and using food for growth, repair, and well-being.
• 📌 Nutrients: Substances in food required for the body's functioning, including carbohydrates, proteins, fats, vitamins, and minerals.

NUTRITION, HEALTH AND WELL-BEING DURING INFANCY (BIRTH-12 MONTHS)

Infancy, spanning from birth to 12 months, is characterized by rapid and phenomenal growth, especially in the first six months. Infants require approximately twice the calories per kilogram of body weight compared to adults engaged in heavy work. This high energy demand is met primarily through breast milk, which is uniquely composed to fulfill all nutritional needs of the infant for the first 4 to 6 months. Key nutrients essential during infancy include protein for muscular growth, calcium for healthy bones, and iron for blood volume expansion. Infants regulate their intake by consuming more or less milk as needed. The mother's nutrition significantly impacts the quality and quantity of breast milk; hence, she must consume a diet rich in protein, calcium, iron, and fluids to prevent malnutrition. The Indian Council of Medical Research (ICMR) provides recommended dietary allowances for infants, specifying energy, protein, vitamin, and mineral requirements. Exclusive breastfeeding is recommended by WHO for six months, with colostrum feeding immediately after birth providing antibodies that protect against infections. Low birth weight infants (less than 2.5 kg) face challenges such as poor sucking reflex and low absorption capacity but benefit greatly from breast milk's antimicrobial properties. Complementary feeding begins at six months, introducing calorie-dense and protein-rich foods while maintaining hygiene to prevent infections. Several low-cost complementary food mixtures using locally available cereals and pulses are recommended. Immunization during infancy protects against common communicable diseases, with vaccines like BCG, OPV, and Hepatitis B administered according to the national schedule. Common health problems in infants include protein-energy malnutrition, anemia, nutritional blindness, rickets, and goitre, often exacerbated by infections and poor sanitation.

• Infants require twice the calories per kg body weight compared to adults doing heavy work.
• Breast milk provides all essential nutrients for the first 4–6 months; exclusive breastfeeding is recommended.
• Colostrum is rich in antibodies and protects infants from infections.
• Low birth weight infants benefit from breast milk but may need supplements if growth is inadequate.
• Complementary feeding starts at 6 months with calorie-dense, protein-rich foods under hygienic conditions.
• Immunization protects infants from communicable diseases; national schedule includes BCG, OPV, Hepatitis B, and MR vaccines.
• 📌 Infancy: The period from birth to 12 months of age.
• 📌 Colostrum: The first yellowish milk produced after birth, rich in antibodies.
• 📌 Complementary Feeding: Introduction of other foods alongside breast milk after six months.
