Nutrition

Nutrition refers to the process by which living organisms obtain and utilize food for energy, growth, and maintenance. It encompasses a variety of biochemical and physiological processes, including the intake of nutrients, digestion, absorption, metabolism, and the excretion of waste. Nutrition is essential for sustaining life and supports vital functions such as immune response, cellular repair, and overall health.

Nutrients are categorized into macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals). Each plays a distinct role in bodily functions, contributing to energy production, building and repairing tissues, and regulating metabolic pathways. A balanced diet, which provides adequate amounts of these nutrients, is crucial for optimal health and well-being.

Nutrition also considers dietary patterns, food choices, and cultural influences, as well as the biological and environmental factors that affect an individual’s nutritional status. It plays a significant role in preventing and managing illnesses, promoting longevity, and enhancing quality of life. Understanding nutrition is vital for making informed dietary decisions and fostering a healthy lifestyle.
