Parents often face the challenge of persuading their children to eat vegetables, with a study from Aston University suggesting that parental facial expressions play a role.
Dr. Katie Edwards, the lead author, highlights the negative impact when a child witnesses a parent displaying disgust while eating vegetables.
Observing Negative Facial Expressions While Eating Reduced Liking for that Food
Edwards and her team noted that humans' observational nature extends to food choices, as they investigated the influence of facial expressions on the liking of raw broccoli. The study revealed that observing others with negative facial expressions while consuming raw broccoli reduced the observers' liking for the vegetable.
In their study, published in Frontiers in Psychology, the team highlighted the noteworthy influence of negative facial expressions on the liking of raw vegetables among adult women. The study involved over 200 young women who watched videos featuring unfamiliar adults consuming raw broccoli with various facial expressions, including positive, neutral, or negative.
Edwards, emphasizing the gender-focused approach, delved into women's reactions, aiming to explore potential differences in modeling eating behavior.
In contrast to previous research findings, the study revealed a significant reduction in liking ratings when participants observed negative facial expressions during broccoli consumption. Surprisingly, positive expressions did not enhance vegetable liking or increase the desire to eat it.
This challenges conventional assumptions about the effectiveness of positive visual cues in promoting healthier eating habits, pointing towards a more complex interplay between facial expressions and food preferences.
Edwards suggests that the observed aversion to visually unappealing foods, regardless of their general likability, may serve as a protective mechanism. Furthermore, the study challenges the notion that smiling while eating is a reliable strategy to boost adults' vegetable consumption.
The intricate relationship unveiled by this research prompts a reconsideration of how facial expressions contribute to the complexities of food perception and preference, providing valuable insights into the dynamics of adult eating behavior.

Study's Findings Can Extend to Children Too
While this study primarily focused on adults, the researchers assert that its implications extend to children as well. Dr. Edwards emphasizes the potential negative impact on children's vegetable acceptance when they witness their parents displaying disgust while eating vegetables.
Unlike previous research, which suggests that behaviors are more likely to be imitated when positive consequences are observed, this study reveals a nuanced correlation.
Participants exposed to clips featuring negative facial expressions experienced a substantial reduction in liking ratings, a pattern not mirrored in the opposite scenario. According to Dr. Edwards, watching someone eat a raw vegetable with a positive facial expression did not enhance adults' vegetable liking or eating desire.
The researchers propose that avoiding visually unappealing food, even if generally liked, might serve as a protective mechanism against potentially harmful consumption. Furthermore, the team challenges the assumption that smiling while eating is an effective strategy for increasing adults' vegetable consumption, suggesting that this might not be a typical display of liking food.
The study's findings underscore the importance of understanding how parental facial expressions can significantly impact children's preferences for vegetables.
