Health and Nutrition is a multidisciplinary field that explores the relationship between dietary intake, nutritional practices, and human health. It encompasses the science of food, nutrients, and how the body uses them to support life, prevent disease, and promote wellness. Nutrition plays a central role in physical development, immune function, mental well-being, and chronic disease prevention.
The field integrates knowledge from biology, biochemistry, physiology, and public health to understand how different nutrients—such as carbohydrates, proteins, fats, vitamins, and minerals—affect bodily functions. It also examines dietary habits, food safety, cultural influences on food choices, and global nutritional challenges such as malnutrition and obesity.
Health, in this context, is viewed not merely as the absence of disease but as a state of complete physical, mental, and social well-being. Maintaining good health requires a balanced diet, regular physical activity, proper hydration, stress management, and avoidance of harmful habits like smoking or excessive alcohol consumption.
Modern nutrition science also emphasizes the importance of lifespan nutrition, considering the specific needs at different life stages—from infancy and adolescence to adulthood and old age.
