The Study
Predatory marketing and false health promotion on social media: risk pathways in diet, fitness, and supplement communication
This study looked at how people who see a lot of fake health stuff online might start believing it and then do risky things, like taking weird supplements. It found that these things are often connected, but it didn’t prove that seeing the stuff makes you believe it—it could be that people who already believe weird things are the ones who watch more of it.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
When you see lots of flashy, emotional health posts on social media, your brain gets confused and starts believing things that aren't true—like that a vitamin can replace medicine. Once you believe it, you're more likely to do risky things like take dangerous supplements.

Exposure to misleading health content on social media leads to risky health behaviors through the influence of false health beliefs, and removing these beliefs from the model weakens the connection between the content and the behaviors.
People who believe government should regulate health content online and who actively avoid misleading health information show smaller negative psychological and behavioral effects when exposed to predatory health content on social media.
Adults aged 18–45 who use social media at least three times per week and are frequently exposed to emotionally charged, pseudo-scientific health content show higher levels of psychological vulnerability, greater belief in false health claims, more engagement in risky health behaviors, and lower perceived health outcomes.
Misleading health messages aimed at older adults often claim that all seniors are unaware of health facts in order to make them follow advice without questioning it.
Younger people who engage in risky health behaviors are more likely to report worse perceptions of their health than older people who engage in the same behaviors.
