'food-related' originates from the combination of 'food' and the suffix '-related', where 'food' refers to any nutritious substance that people or animals eat or drink, and '-related' indicates a connection or association.

'Food' comes from Old English 'fōda', while '-related' is derived from the Latin 'relatus', meaning 'brought back'.

Initially, 'food' meant any substance consumed to provide nutritional support, and '-related' meant connected to. The combined term 'food-related' has maintained this meaning.
