Are Eating Habits Socially Transmitted?

Are Eating Habits Socially Transmitted? A new study has found that social norms and choices by those we are eating with influence our own food choices.

Researchers in the United Kingdom recently conducted a systematic review of 15 experimental studies. Eight of the studies examined how information about food intake norms influenced food consumed by participants. Seven other studies reported the effects of food choice norms on how people decide what food to eat.

After examining the data, researchers reported they found consistent evidence that social norms influence food.

The meta-analysis found that if participants were given information indicating that others were making low-calorie or high-calorie food choices, it significantly increased the likelihood that they made similar choices.

The data also indicated that social norms influence the quantity of food eaten, according to the researchers.

Additionally, the review indicated that suggesting that others eat large portions increased food intake. The researchers also found there was a strong association between eating and social identity.

“It appears that in some contexts, conforming to informational eating norms may be a way of reinforcing identity to a social group, which is in line with social identity theory,” explained lead investigator Eric Robinson, Ph.D., of the University of Liverpool.

“By this social identity account, if a person’s sense of self is strongly guided by their identity as a member of their local community and that community is perceived to eat healthily, then that person would be hypothesized to eat healthily in order to maintain a consistent sense of social identity.”

The need to solidify our place in our social group is just one way researchers found social norms influence our food choices. The analysis also revealed that the social mechanisms that influence what we decide to eat are present even when we eat alone or are at work — and whether we are aware of it or not.

“Norms influence behavior by altering the extent to which an individual perceives the behavior in question to be beneficial to them,” Robinson said. “Human behavior can be guided by a perceived group norm, even when people have little or no motivation to please other people.

“Given that in some studies the participants did not believe that their behavior was influenced by the informational eating norms, it seems that participants may not have been consciously considering the norm information when making food choices.”

The researchers caution that while more research is needed, these types of studies can help us understand the way people make decisions about food and can help shape public policy and messages about healthy choices.

“The evidence reviewed here is consistent with the idea that eating behaviors can be transmitted socially,” said Robinson.

“Taking these points into consideration, the findings of the present review may have implications for the development of more effective public health campaigns to promote ‘healthy eating.’

“Policies or messages that normalize healthy eating habits or reduce the prevalence of beliefs that lots of people eat unhealthily may have beneficial effects on public health.”

The study was published in the Journal of the Academy of Nutrition and Dietetics.
