Sustainable agriculture and food systems.Sustainable agriculture aims to meet society’s need for food and keep the air and water clean. Scientists in this field seek ways to provide enough food and save thriving ecosystems for future generations. Sustainable agriculture studies agroecosystems’ biological, ecological, and economic components.
Food science.The basis of food science is understanding the food components, such as proteins, carbohydrates, fats, and water. This multi-disciplinary field studies chemistry, biochemistry, and engineering to solve problems associated with the food system. Food science is a relatively new and growing discipline and exciting to investigate!
Human nutrition.Human nutrition is the science of food, nutrients, and balance concerning health and disease. It is another subject with an interdisciplinary character, which involves physiology, biochemistry, psychology, and anthropology. The social aspect of human nutrition focuses on beliefs, preferences, and cultural traditions regarding food choices.
Social and behavioral nutrition.Social and behavioral nutrition is based on the understanding that human eating habits are influenced by social norms, access to resources, and structural constraints and opportunities. This discipline aims to demonstrate the nutritional status of groups like women and children and create new nutrition services and commodities.
Nutritional diseases.Nutritional diseases include malnutrition, obesity, metabolic and eating disorders, and other severe chronic diseases. Nutritional science, genetics, and computer science address the causes of such illnesses and suggest possible treatments. Another mission is to prevent these diseases.
