If you've been on social media lately, y'all might have noticed a few posts about food — okay, a lot of posts about food.

These range from artistic photos of restaurant meals, to daily updates on your friends' keto or paleo nutrition, to their guilty confessions of late-night fast food runs.

Whatever people in your online social circles are proverb well-nigh food, there's a good chance that y'all know a lot near their eating habits and food preferences.

This data provides clues almost the social norms of your online circles when it comes to food, which the authors of a new report say may shape your own eating habits.

"This study suggests nosotros may be influenced by our social peers more than than nosotros realize when choosing certain foods. We seem to be subconsciously accounting for how others behave when making our ain food choices," said study author Lily Hawkins, a PhD educatee at Aston University in Birmingham, UK, in a press release.

Alix Timko, PhD, a researcher at PolicyLab at Children'due south Hospital of Philadelphia (CHOP) and a clinician-scientist in the Eating Disorder Cess Treatment Programme at CHOP, pointed out that the new study doesn't wait straight at how social media affects people'south eating habits.

Instead, researchers examined how different types of social norms affect people's consumption of certain foods.

These social norms also exist in other situations, such equally in the existent world among academy students or co-workers.

But researchers focused on social media because these sites now brand up a large corporeality of our social interactions.

In the study, researchers asked 369 university students nearly their consumption of fruits, vegetables, free energy-dense snacks, and sugar-sweetened beverages, likewise as their Facebook and other social media use, and perceptions about their online friends' eating habits and preferences.

It turns out that even in the online world, social norms can bear upon people's eating habits — in two specific means.

"When individuals think that other members of a group consume more servings of fruits and vegetables and/or eat fruits and veggies more than frequently, they report eating more fruits and veggies [themselves]," said Timko, who's besides an assistant professor of psychiatry at the Perelman Schoolhouse of Medicine at the University of Pennsylvania. She wasn't involved in the new study.

The second effect has to practice with what we call up nosotros should be doing.

"When high energy-dense and sugar-sweetened potable consumption were considered," said Timko, "only how many servings of high energy-dense snacks or sugary beverages individuals thought that Facebook users should eat predicted participants' consumption."

The researchers also looked at whether social norms were linked to a person's body mass index (BMI). They weren't, although the researchers say this may be because information technology takes longer for overweight or obesity to evidence up.

The written report was published online February 6 and will appear in the journal Appetite in the June 2020 upshot.

Social norms such as these have played a part in many public health campaigns — such every bit "don't potable and drive" and teen anti-vaping campaigns — where behaviors are identified equally being what well-nigh people exercise.

The authors of the new study think that their work could too be used to encourage people to swallow more fruits and vegetables and less high energy-dense snacks and sugar-sweetened beverages.

"The implication is that nosotros can use social media as a tool to 'nudge' each other's eating beliefs within friendship groups, and potentially apply this cognition as a tool for public health interventions," said Hawkins.

There's a lot of room for improvement in these areas.

Merely 12.2 per centum of American adults ate the recommended servings of fruit, according to the Centers for Disease Command and Prevention (CDC). Just ix.3 percent ate the recommended servings of vegetables.

In addition, 36.6 percent of adults ate fast food on any given day, while 49 percent drank a sugar-sweetened beverage, reports the CDC.

Timko said social media could exist used to show "pictures of beautiful dishes of veggies and fruits" alongside data virtually social norms. This might encourage people to eat more than of these foods.

These kinds of public health campaigns, though, will have to walk a fine line, considering labeling certain foods equally "salubrious" or "unhealthy" tin can as well imply that they are "practiced" or "bad."

"This attaches a moral value to nutrient and can inadvertently shame people who eat foods that are perceived equally 'unhealthy' and praise those who swallow 'healthy,'" said Timko.

She said this is partly how social norms work, but this type of messaging tin can increment the risk of disordered eating.

Caution may be especially needed with social media messaging, because some enquiry shows a link betwixt social media use among teens and matted eating behaviors such as worrying about their weight or shape, skipping meals, rampage eating, or exercising excessively.

Still, "whenever one decides to curate these types of messages," said Timko, "it is really important to think of the potential negative effect that they have."
