Nutrition

Nutrition is the process by which living organisms obtain and utilize food substances to support growth, maintenance, reproduction, and overall health. It encompasses the study of nutrients in food, their roles in the body, and the biochemical processes involved in the digestion, absorption, transport, metabolism, and excretion of these nutrients. Key components of nutrition include macronutrients (carbohydrates, proteins, and fats), micronutrients (vitamins and minerals), and water. Good nutrition is essential for energy production, cellular function, and the prevention of diseases, while poor nutrition can lead to health issues such as obesity, malnutrition, and chronic illnesses. The field of nutrition also explores dietary choices, food systems, cultural influences on eating habits, and the impact of nutrition on physical and mental well-being.
