It was the small, slightly tart, purple plums that recently caught my eye as I passed the grocery store’s produce aisle.
In an instant, I was back in my mother’s cheery kitchen with the pretty flowered wallpaper. I was sitting at her old oilcloth-covered Formica table anxiously awaiting a slice of the delicious Pflaumenkuchen (plum cake) that could only be baked each autumn with this seasonal fruit. I can still remember that warm and loving feeling, as if it happened yesterday, not 80 years ago.
Scientists echo that a sense of well-being can come from the whiff and taste of foods reminiscent of our pasts. According to a 2023 abstract titled “The Proust Effect: Scents, Food and Nostalgia” published in PubMed, the physiological effect triggered by taste and smell can be profound:
“Nostalgic memories triggered by taste and smell are especially self-relevant, arousing and familiar,” the abstract cites. “These memories have an even more positive emotional profile than nostalgic memories elicited by other means … Scent-evoked and food-evoked nostalgia also confer numerous psychological benefits, including enhanced self-esteem, feelings of social connectedness and deeper meaning in life."
For example, as a youngster when you were sick, your mother made your favorite soup to help you feel better. Even decades later, the savory taste of that soup still evokes memories of feeling cared for and loved. Think about the old Campbell’s Soup commercial with soups that were oh-so-good and how those soups bring comfort decades later, with memories of our moms who served them up.
No one expressed food nostalgia in literature better than French author, Marcel Proust, more than 100 years ago. Proust, in his book In Search of Lost Time, wrote that eating a Madeleine, a popular small French cake, dipped in Linden tea, immediately transported him back to happy times in his childhood. This anecdote is an example of what scientists refer to as an “involuntary memory” when a smell or taste unexpectedly unlocks a happy past recollection.
Food memories are often stronger when they utilize all the senses — smell, taste, touch, sight and even hearing, but some research has shown that smell alone can also trigger strong memories.
