- Research shows that parents’ facial expressions may be the cause
- Seeing others visibly dislike vegetables can lead to onlookers disliking them
Mothers and fathers are known to have difficulty getting their children to eat their vegetables.
And now a study suggests that parents’ facial expressions may be to blame.
Researchers from Aston University found that seeing others visibly dislike vegetables can lead onlookers to dislike them too.
Dr. Katie Edwards, lead author of the study, said: ‘If a child sees his or her parents showing disgust while eating vegetables, this could have negative consequences for children’s acceptance of vegetables.’

In the study, the researchers wanted to investigate whether watching someone else eat influences your own preferences.
The team enlisted just over 200 young women, who were shown a video of an unknown adult eating raw broccoli.
While eating, the model in the video had a positive, neutral or negative facial expression.
After watching the video, participants were asked about their taste and desire to eat raw broccoli.
Previous research has shown that behavior is more likely to be imitated when positive consequences are observed, while the reverse is true when negative consequences are observed.
However, in this new study, this correlation was only partially seen.
Participants who saw the clips with negative facial expressions saw a greater drop in like ratings, while the reverse was not true.
‘Watching others eat a raw vegetable with a positive facial expression did not increase adults’ taste or desire to eat,’ Ms Edwards explained.
Although the reason for this remains unclear, the researchers suggest that avoiding foods that seem disgusting may protect us from eating something harmful.
Meanwhile, smiling while eating is not a typical expression of liking food, Ms. Edwards said.
“This could imply that watching someone eat a raw vegetable with positive facial expressions does not appear to be an effective strategy for increasing vegetable consumption in adults,” she said.
This particular study focused on adults, although the researchers say the findings could be generalized to children as well.
