Nutrition

Nutrition is the science that studies the interactions between living organisms and the substances they consume for sustenance. It involves the processes by which organisms obtain and utilize food, including the intake, digestion, absorption, metabolism, and excretion of nutrients. Nutrition is essential for growth, development, maintenance of health, and the prevention of diseases. It encompasses the study of the biochemical and physiological effects of nutrients, their role in bodily functions, and how dietary choices impact overall health. Key components of nutrition include macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals), as well as water, which are all vital for energy production, cellular repair, and regulation of bodily processes. Proper nutrition is crucial for optimal physical and mental performance, and it is influenced by various factors, including culture, lifestyle, and food availability.
