Smell is experienced when odour particles are detected in the air and then enter the nose through the mouth or nostrils. When we chew and swallow food, odours can be released that travel through the back of the mouth and into the nasal passage.

We experience taste when food or drink, mixed with saliva, reaches tastebuds all over the tongue and inside the mouth. The tastebuds will detect the five basic tastes of sweet, sour, bitter, salty and savoury (also known as umami). These building blocks of flavour combine with sense and touch, giving rise to many flavours. There are ways of managing these changes and make food more appealing.Īround 80% of people undergoing cancer treatment report changes in the flavour of food.
