A new study says that eating vanilla yoghurts with lower fat content gives people a stronger positive emotional response.
"We were surprised to find that by measuring emotions, we could get information about products independent from whether people like them," said lead author Jozina Mojet from Food & Biobased Research, Wageningen University in the Netherlands.
‘To determine the effect of different yoghurts on people's moods, the researchers used a new method called an emotive projection test and found that vanilla yoghurt elicited a strong positive emotional response in people.’

Three groups of at least 24 participants were each given a pair of yoghurts to taste. The pairs of yoghurts were of the same brand and were marketed in the same way, but had different flavors or fat content. The team then tested their emotions using four methods, including the new emotive projection test.
The researchers found that vanilla yoghurt elicited a strong positive emotional response, supporting previous evidence that a subtle vanilla scent in places like hospital waiting rooms can reduce aggression and encourage relationships among patients and between patients and staff.
The team also looked at the sensory effect of the yoghurts. There was no difference in the emotional responses to strawberry versus pineapple yoghurts, but low-fat versions led to more positive emotional responses.
The research was published in the journal Food Research International.
