Scrolling through Facebook or Instagram, it can be easy to feel drawn in by the people you follow. Whether it’s the brands they’re buying, the things they’re doing or what they’re wearing, it’s not uncommon to want to follow suit — they’re called “influencers” for a reason, after all.
This isn’t only true of those who are paid to influence, however: those we know in “real life” and follow on social media can also impact the decisions we make. In a new study published in Appetite, Lily Hawkins and colleagues at Aston University find that what we think our online friends are eating can influence how healthy (or not) our own diets are.

“You wouldn’t like me when I’m angry”: for the more mild-mannered among us, Bruce Banner’s famous catchphrase may not resonate. But add some hunger — “you wouldn’t like me when I’m hangry” — and many of us can start to relate.
Being hungry, whilst a daily occurrence, can have multiple negative psychological impacts. For one, and most obviously, it simply doesn’t feel good, often leading us to the aforementioned rattiness of “hanger”. But acute hunger has also been linked to an increase in self-interest and a decrease in helping behaviour, too. If your resources are low, the theory goes, you’re much less likely to cooperate with others as you want to keep food for yourself and are unwilling to expend valuable resources like time and energy on helping others.
But this isn’t always the case — at least not according to a new piece of research from Nature Communications. The team argues that acute hunger doesn’t always have an impact on prosociality, even though people strongly believe it does.

Going home from dinner out with a friend or a Sunday family lunch, you may notice you feel slightly more full than you normally do after eating. And while some of this may have to do with how many potatoes your mum insists you eat, new research seems to suggest that there could be something else going on. Researchers analysing dozens of past studies on the “social facilitation” of eating have confirmed that people do tend to eat more when eating in groups than alone — and have come up with several social and psychological mechanisms that could explain our increase in consumption in company.

With increased concern about the impact of meat on our health and the environment, and an ever-expanding selection of meat-free products available to buy, popular interest in vegetarianism and veganism has steadily grown.
But for those who want to cut down but aren’t quite ready to give up their burgers, there is a third way: flexitarianism. As a 2019 study from the University of Nottingham on red meat and heart health put it, you “don’t have to go cold turkey on red meat to see health benefits”, finding that halving the amount of red and processed meat eaten can have significant health benefits.
A flexitarian tries to cut down their consumption as much as they can, but still eats the occasional meal or snack containing meat. One recent piece of market research found that 14% of the UK consider themselves flexitarian, and though more formal research would clearly be needed to paint a more critical and comprehensive picture, these figures do seem to suggest something of a cultural preoccupation with how much meat we’re eating.
Now new research, published in Social Psychological and Personality Science, has taken a look at how such an approach impacts identity as well as health. The choice to be vegetarian can be a significant source of social identity — but how do flexitarians see themselves?

Fast food chains are not exactly renowned for encouraging healthy eating. But in a new study a team of psychologists, eager to turn that assumption on its head, chose McDonald’s as their target for a somewhat unconventional, psychologically-informed health intervention. Writing in Psychology & Marketing, the researchers report successfully “nudging” a group of Coca-Cola-guzzling customers into opting for its sugar-free counterpart, Coke Zero — simply by changing the order of options on the menu.

A new paper in Psychology and Psychotherapy: Theory, Research and Practice argues that the relationship a person has with their eating disorder is shaped by that person’s understanding of what meaningful relationships should look like – and, in turn, this can have important consequences for the severity of their disorder.
In particular, Emma Forsén Mantilla and her team from the Karolinska Institute in Sweden wanted to better understand eating disorders through “attachment theory”. This is the idea that relationships with primary caregivers become scripts that we lean on to tell us how relationships “work”.

When you’re in the coffee shop and you watch your hand pick up the muffin and place it on your tray, how much of this was down to the situation, and how much to do with your (lack of) willpower or your long-term intentions? A new study in the British Journal of Health Psychology compared these influences and found that momentary cues, such as seeing someone else snacking, were more strongly associated with how much people snacked than their own baseline psychological traits and intentions.

Fussy eating – also referred to as “selective eating” in scholarly research – is incredibly common among children, with upper estimates placing the prevalence at 50 per cent. Despite this, many parents understandably fret when their kids avoid a lot of foods, won’t try new things and/or will only eat certain meals. They worry whether their child is getting enough vitamins and if their child’s fussiness is some kind of precursor to later more serious eating problems.
A new, small study in Eating Behaviors is the first to document how fussy eating develops in the same individuals over time into early adulthood and may provide a crumb (sorry) of comfort for anxious parents. It’s true that 60 per cent of fussy eating children in the study were also fussy eaters at age 23, but fussy eating young adults were no more likely to report signs of eating disorder than their non-fussy peers.

Crisps, coke, and chocolate bars. What might be a special treat for some of us, is now a multi-billion pound industry and a staple of many people’s diets. Advertising campaigns from the snack food companies, often starring sports stars, send the message that we can offset any adverse effects of consuming their products simply by getting more physical exercise. But you can’t really “run off” a burger – recent studies show a lack of exercise is not to blame for rising obesity rates, bad diets are the real driver.
Interventions to help reduce junk food consumption are especially important for children and adolescents – prevention is better than cure in this context because obesity is so difficult to treat. Unfortunately, while health education in the classroom has shown some success among young children, adolescents have been notoriously hard to reach.
But now a large-scale study published in PNAS has tried an innovative approach to change teenagers’ attitudes towards healthy eating, and the results are promising. The researchers, led by Christopher Bryan at the University of Chicago and David Yeager at the University of Texas at Austin, argued that previous interventions have probably been unsuccessful because of a major flaw: they focused on a future, healthier you and assumed that this would be enough motivation for adolescents. In contrast, the new intervention cleverly exploits teenagers’ instinct for rebelliousness and autonomy, and the value they place on social justice.
