Why is sense of smell important to our sense of flavour
Smell is also important as it can affect our sense of taste. Researchers say 80 percent of the flavors we taste come from what we smell, which is why foods can become flavorless when you have a blocked nose. Taste buds on our tongues can only identify four qualities being sweet, sour, bitter and salt and the remaining ‘tastes’ are actually distinguished by smell.
Effects from loss of smell?
As smell is so closely connected to taste when smell is impaired it can cause people to actually change what they eat. Without smell food becomes tasteless and this results in people adding salt to improve the flavour. Adding salt can in itself be an issue for those with conditions such as blood pressure, kidney disease, diabetes or heart conditions.
In extreme cases smell deprivation has been seen to lead to depression. Problems with our sense of smell has also been linked to early warning signs for more serious health problems such as Parkinson’s disease, Alzheimer’s disease, or multiple sclerosis.
