In a nutshell, food science is the scientific study of food from the period of harvesting, processing, storage and packaging. Human nutrition now is concerned with the utilization of this food in the human system. Because both cases are referring to food, it shows that both terms are inter-related. Actually, food science plays significant roles in human nutrition as it broadens our horizon on the foods we consume. Some of the roles of foods science in human nutrition includes: food processing as it as shown variable ways in which one food commodity can be processed into different forms; food fortification and enrichment in which nutrients that were not present or that were present but lost during processing are added to the food at even greater levels; and also food preservation and storage which show us how to keep our foods safe for future use.
