But an expert says even just one teaspoon of peanut butter could give us the same dose of happiness as spooning in bed for 30 seconds.
Psychologist Emma Kenny explains that peanut butter featues tryptophan, an amino acid responsible for producing serotonin in the body, meaning just a small portion could provide an instant mood lift.
The study also revealed that even the way people eat their food can impact how happy they feel, as 43% found that spooning the popular spread out of a jar made them feel just as good as cuddling a partner.
‘The human body is absolutely incredible, and there are small actions that we can all take every day to get the best from it,’ said Emma Kenny.
‘We instinctively know that spooning with someone makes us feel better. But what is interesting from the research is finding out the quantity and quality of spooning required in order to feel good.
‘As we encounter quite a depressing time of year, it’s something we could definitely do with right now.
‘Either half a minute of spooning with someone or a 15g spoonful of peanut butter provides that serotonin boost that we all need.
‘Of course, a double whammy of both will be even better.’
The study also looked into other activities that make Brits happy.
Other favourite pastimes for a serotonin boost include watching TV/ films (59%) and raiding the kitchen cupboards for snack foods (54%), reading a good book (37%) and connecting with old friends (32%).
All things to keep in mind as we head into the cold and dark winter months.
