Thursday 6 October 2022 12:28 PM How the smell of food can enable 'TIME TRAVEL' trends now
Whether it's the pizza you ate on your first date or the burger you devoured in hospital after giving birth, many of our fondest memories are often associated with certain foods.
Now, a study has shown how the smell of these foods can actually enable 'time travel.'
Researchers from Lancaster University exposed older people to flavours from their youth, and found they enhanced their memories of key events.
The team hopes the findings could pave the way for a new technique to help dementia patients reconstruct memories.
Dr Vaiva Kalnikaitėsaid, an author of the study, said: 'We finally have technology that can help re-construct memories using the flavour and scent of different foods in very compact shapes. These are the strongest cues to help us remember.'

Dementia is an umbrella term used to describe a range of progressive neurological disorders, that is, conditions affecting the brain.
There are many different types of dementia, of which Alzheimer’s disease is the most common.
Some people may have a combination of types of dementia.
Regardless of which type is diagnosed, each person will experience their dementia in their own unique way.
Dementia is a global concern but it is most often seen in wealthier countries, where people are likely to live into very old age.
How many people are affected?
Alzheimer’s Research UK reports there are more than 850,000 people living with dementia in the UK today.
It is estimated that the number of people living with dementia in the UK by 2025 will rise to over 1 million.
In the US, it's estimated there are 5.5 million sufferers. A similar percentage rise is expected in the coming years.
As a person’s age increases, so does the risk of them developing dementia.
Rates of diagnosis are improving but many people with dementia are thought to still be undiagnosed.
Is there a cure?
Currently there is no cure for dementia but new drugs can slow down its progression and the earlier it is spotted the more effective treatments are.
