Food system               The food system includes all interrelated activities involving the production, processing, transport and
                          consumption of food.62
Food industry             The food industry encompasses a series of industrial activities directed at the processing, conversion,
                          preparation, preservation, and packaging of foodstuffs.63
Nutrition care            Any practice that aims to improve the dietary intake of a patient to improve health outcomes.64
Nutrition science         Nutrition science deals with all aspects of the interaction between food and nutrients, life, health and
                          disease, and the processes by which an organism ingests, absorbs, transports, uses and excretes food
