Trending tweets greatest amplifier of dodgy diets
Health and nutrition among the most common topics where misinformation is shared on social media
New research by University of Wollongong PhD student Melissa Eaton shows that retweeting is the greatest amplifier of fad diet posts on Twitter.
As social media continues to transform the way we communicate, Melissa Eaton explored how people talked about fad diets on Twitter and the relationship between these conversations and mental health.
An Accredited Practising Dietitian, Ms Eaton presented her research at the 2021 Dietitians Australia National Conference (11-13 July)
“While social media is a way we connect online, we found that those who use Twitter mostly reshared ‘fad diet’ posts, rather than talking to each other about the diet,” she said.
“Even for those who had just a few followers, retweeting allowed their message to be shared far and wide. This shows that the messages we post on social media have the power to influence more people than we realise.”
Within a team of researchers, the PhD student from the UOW School of Medicine examined conversations about fad diets. These were defined as diets that promised quick weight loss with minimal effort through the restriction of macronutrients or certain foods, rather than encouraging sustainable, long term dietary change.
Health and nutrition are some of the most common topics where misinformation is reshared, and as fad diets can make unreasonable health claims, they are a clear example of this.
“Social media allows global communities to easily connect and share their views on the things they are passionate about. Given how easy it is to share these messages through retweeting, it’s important to take a moment to consider the credibility of a message before reposting,” Ms Eaton said.
“While there might be evidence to support the use of a certain diet for a particular group of people, it becomes an issue when restrictive diets are promoted as a ‘cure-all’ way of eating for the general population.”
This study also found an emerging association between mental health and online communication of fad diets, including a potential link between restrictive diets and poorer mental health.
“While more data is needed to better understand this link, it highlights that it’s important for influencers to encourage their followers to seek information that is right for their health, rather than following the blanket advice of others,” Ms Eaton said.
“Social media shows us the topics that are trending – and as health professionals we need to work together as a community to reshare posts that supports people interested in nutrition to access the right information.”
When reading nutrition information on social media, she shares this advice:
“Be sure to follow those with qualifications in nutrition and dietetics – and steer clear of posts that promote quick-fixes and encourage things like detoxes and cure-all diets.
“At the end of the day, we all have individual health needs – so it’s best to seek nutrition information that is tailored to you from an Accredited Practising Dietitian.”
