næringarfræ

Næringarfræ is the Icelandic word for nutrition science. It is the study of how food and drink affect the health and well-being of an organism. This field examines the processes by which the body absorbs, metabolizes, and excretes nutrients from food. It also investigates the roles of carbohydrates, fats, proteins, vitamins, minerals, and water in maintaining bodily functions, growth, and disease prevention.

The practice of næringarfræ encompasses a wide range of disciplines, including biochemistry, physiology, and public health. Professionals in this field often work as registered dietitians or nutritionists, providing guidance on healthy eating habits, managing dietary needs for specific medical conditions, and developing nutritional strategies for individuals and populations. Research in næringarfræ aims to understand the complex interactions between diet and health outcomes, contributing to evidence-based recommendations for optimal nutrition. This can involve studying nutrient deficiencies, the impact of processed foods, the benefits of certain dietary patterns, and the influence of nutrition on chronic diseases such as obesity, diabetes, and cardiovascular disease. The ultimate goal is to promote health and prevent illness through informed dietary choices.
