How Social Media Feeds Are Quietly Warping Your Eating Habits
Social media has made food and nutrition information more accessible than ever. However, because platforms are designed to reward views and engagement over accuracy, the same feeds that can offer beneficial content also may amplify misinformation, negatively shape eating habits and drive food anxiety or body dissatisfaction.
While our food environment may have historically been what our friends and family eat, food advertising, grocery stores and restaurants, social media has expanded that environment. It now includes a nonstop and highly personalized stream of wellness advice, supplement recommendations, recipes, grocery hauls, “What I Eat in a Day” videos and warnings about allegedly harmful foods.
Chelsey Amer, MS, RDN, owner of Chelsey Amer Nutrition , says, “Social media and the drive to go viral have made messages about nutrition and food very extreme and black and white, whereas nutrition is extremely nuanced.” When someone with a large platform says something about food, even without the education, credentials, and evidence to back up their claims, what they say is often believed to be the truth, she explains. “As a result, there’s a lot of fear around perfectly healthy foods, skewing the perception of what most people believe to be healthy.”
It should be noted that not all social media exposure has the same effect. A lot depends on what someone sees, how often they see it and whether the content they see centers on recipes, health education, weight, appearance or food fears. While there can be some positives to the availability of food related content, it’s important to be aware of the potential for harm.
Social media really can influence what people eat
Research has actually shown that social media really does impact people’s eating habits. For example, a 2024 systematic review of 38 studies examining eating-related social-media content. The researchers found associations between exposure to certain types of content (specifically, fast-food advertisements, clean-eating content and eating videos) and body-image concerns, disordered eating and consumption of foods shown online—or a willingness to consume those foods shown.The evidence varied depending on the type of content. For example, content focusing on health food did not appear to have the same link.
A 2025 review of 16 studies also found that exposure to food-related social media was associated with disordered eating patterns and poor body image, depending on the type of content. While more research is needed, it’s clear that there are links that need to be addressed.
Researchers believe that a few mechanisms at work are exposure and repetition, algorithms tracking your viewing habits so it send you more of the same, social norms and influencer identification that consumers view as peers rather than advertisers.
Maya Feller, MS, RD, CDN is the founder and lead dietitian at Maya Feller Nutrition , founding clinical advisor of GT Foods, author of Eating from Our Roots . She explains, “Social media is a tricky space. Between the misinformation, disinformation, and partially credentialed pseudo-experts talking about food, there is no shortage of options. People who are easily influenced are more likely to equate a large following with credibility.”
“The algorithm rewards creators for posting more frequently and spending lots of time on the app. Spending time on the app is not equivalent to evidence-based education. Since the algorithm feeds the user what they want, their food choices and beliefs are more likely to be shaped by what they are being served,” says Feller. “If the information is steeped in fear and conspiracy, then that’s the bulk of the exposure. I’ve had patients who, despite working with me, have asked if they too should consider raw milk and colostrum supplementation because both appeared to be popular and were said to be beneficial across socials. That’s very powerful.”
While there are some things to be cautious about, there are some potential positive aspects of social media use when it comes to healthy eating. For example, on social media platforms, you can find recipe inspiration and meal prep ideas, practical cooking techniques, seeing approachable examples of healthy behaviors that may make them feel more achievable, finding credentialed nutrition experts, getting exposure to unfamiliar food cultures and connecting with others who may be managing similar health or life experiences, helping people feel less alone.
Nutrition consultant and author Jaclyn London, RD shares a few examples: “Parents of toddlers can trade ideas for healthy snacks their kids might actually eat. A caregiver whose parent is going through chemotherapy can find high-protein meal ideas from people dealing with the same challenges. Those micro-communities can provide information, but they also provide support and connection. And that can have a meaningful impact on both physical and mental health.”
A 2025 study of 488 Taiwanese adults ages 30-45 found that engaging with healthy cooking videos on social media was associated with healthier eating behaviors. While the study, which was cross sectional in design, doesn’t show that watching these videos definitively caused the healthier behaviors, it does establish a link.
A 2025 randomized trial that included 558 college students also looked at recipe-based social media content. While the message format and repetition didn’t lead to huge differences, the visually informative content was associated in this study with more favorable attitudes and intentions related to cooking, suggesting that this content may contribute to influencing people to cook. However, this was a small study so further research would be needed to establish more conclusive insight.
So while simply posting “healthy” content doesn’t automatically change behavior, social media may be well suited to provide inspiration and practical food literacy.
While social media does offer some potentially positive effects, nuance still matters. However, algorithms don’t reward nuance accuracy.
Dietitian Keri Gans , Podcast Host of The Keri Report and Forbes Health Advisory Board Member, says, “Social media has made nutrition information much more accessible, but it has also made food feel more complicated than it needs to be. I see people growing fearful of certain foods or ingredients because they’ve repeatedly heard they’re ‘toxic,’ inflammatory, or too processed. Ultra-processed foods are a good example; there’s an important conversation to have about nutrition, but social media often strips away nuance and reduces it to a list of foods to avoid.”
London adds, “The algorithms can compound the problem. You don’t even have to ‘like’ a post to signal interest; something as simple as spending more time watching it can influence what you’re served next. That makes it incredibly easy to go down a rabbit hole where your feed becomes increasingly saturated with dieting, body-checking, restrictive eating or other content that reinforces the exact thoughts and behaviors you may already be struggling with.’
Inaccurate food and nutrition information that’s viral on social media can have very real physical consequences, says London. “People are taking multiple supplements because they’ve seen each one recommended online without considering interactions or cumulative doses. I’ve seen people doing extreme challenges end up in the hospital after drinking excessive amounts of water. At the other end of the spectrum, people avoid otherwise nutritious foods because an influencer told them an ingredient is ‘toxic.’”
A 2025 study looking at “What I Eat in a Day” videos on TikTok found that many posts lacked transparent disclosures or sourcing, where applicable, and did not offer balanced discussions about health risks and benefits. Additionally, only 36% were found to be completely accurate when reviewed, with significant portions being rated partly or completely inaccurate. Researchers also found that engagement was not tied to accuracy.
A 2025 review of 28 publications that looked at nutrition misinformation on social media found recurring misinformation around unsupported nutrition claims. The researchers suggested that healthcare professionals and academic organizations provide credible alternatives.
What makes this challenging, however, is that, when compared to a lot of the content that gains attention, accurate nutrition information often sounds comparatively boring.
Statements like “Eat a variety of foods,” “Dietary patterns matter more than individual ingredients” and “Context and dose matter” are much harder to package than things like “NEVER eat this” or “This food will wreck your hormones.”
When “healthy eating” becomes food fear
There is a point at which an interest in healthy eating tips over into overwhelm or even full-on food fear, where someone may be scared to eat foods that are actually safe when eaten as part of an overall healthy diet.
A few recent examples are seed oils and ultraprocessed foods. Amer says that repeated exposure to misinformation about the dangers of a food can skew consumers’ perceptions about that food. “The best example right now is the fear around seed oils. The evidence shows that seed oils are perfectly healthy and can even support heart health, but social media has made people so fearful of seed oils.”
Gans echoes that this has happened with ultra-processed foods as well. “There’s an important conversation to have about nutrition, but social media often strips away nuance and reduces it to a list of foods to avoid.”
Nutrition science asks questions like, “Under what conditions, what dose, and in which population?” Social media reduces the conversation to “is this food good or bad?”
For example, an important nuance that algorithms don’t pick up on is that the main health concern with seed oils is actually about having too much omega-6 fatty acids (of which seed-based oils are a source) and not enough omega-3 fatty acids. And when it comes to ultraprocessed foods, how detrimental they are to health depends a lot on how much and how often a person has them—and what the rest of their usual diet entails. There’s also a lot of confusion amongst consumers about what exactly “counts” as an ultra-processed food.
That binary framing can lead to issues like unnecessary food avoidance, potentially unsafe supplement stacking, anxiety about ordinary ingredients, overthinking food shopping decisions and even disordered eating.
London adds, “People become so overwhelmed by conflicting advice that they reach the point of saying, ‘I give up. I have no idea what I’m supposed to eat anymore.’” Good, high quality nutrition information, she explains, should make you feel more confident and empowered about feeding yourself and your family. “It should make eating healthier easier and more fun instead of leaving you worried that every decision you make is the wrong one.”
Amer says, “There are a lot of examples of disordered eating and unhealthy eating behaviors on social media.” Exposure to “What I Eat in a Day” videos, especially when paired with body checking —think: ab shots— or an implied message that eating like the creator of that video will make your body look like theirs, can be especially problematic. They can drive comparison and, she adds, they can lead to unrealistic expectations and even perpetuate disordered eating.
London says, “Social media creates this constant opportunity to compare yourself to everyone else: How you look, what you eat, how much you exercise, what supplements you take, how ‘healthy’ or ‘clean’ your food is, how productive you are. There’s this pervasive feeling that you’re behind, you’re not enough, or there’s always something else you should be doing better. That can be incredibly isolating and damaging to mental health, especially when it comes to body image. We already have substantial research linking social media use—particularly appearance-, diet- and weight-focused content—with body dissatisfaction, disordered eating and eating-disorder symptoms.”
The research backs this up.
A 2025 review and meta-analysis involving 55,440 participants found moderate associations between more online social comparison and body image concerns and eating disorder symptoms as well as were body image.
A 2025 systematic review and meta-analysis of 83 studies involving 55,440 participants found moderate associations between greater online social comparison and both body-image concerns and eating-disorder symptoms. Greater comparison was also associated with lower positive body image. A separate meta-analysis found that exposure to social media imagery focused on idealized appearance can negatively impact body image.
A 2023 randomized experiment that included 421 women ages 18 to 21 found that even brief exposure to TikTok videos with a diet culture focus increased food restriction and urges to exercise when compared with diet-neutral content. In contrast, anti-diet content viewing was associated with improvement in body satisfaction and more intuitive eating habits.
A 2023 analysi s of the #HealthyLifestyle hashtag on TikTok found that many seemingly positive wellness messages co-existed with negative body image and diet culture messaging. Similarly, a 2024 analysis of TikTok videos using popular hashtags related to diet found that over half of them involved body checking. Regardless of whether they were credential experts or not, more than half of the creators presented themselves as experts and provided nutrition advice.
Younger social media users have been found to be especially susceptible to messaging about food and body image. While not all social media has a negative effect, certain types associated with body image and disordered eating patterns may contribute to symptoms in young people repeatedly exposed to that content. A 2022 review focusing on adolescents found that social media influenced food choices through celebrity endorsement, peer influence, food advertising, influencer content and social norms related to food and eating.
How to scroll without letting your feed dictate your diet
While social media has potential to impact your diet, it doesn’t have to be that way. There are steps you can take to safeguard your scrolling. Here are some key questions dietitians recommend asking yourself to help you keep a clear head when engaging with food and nutrition content on your feed:
Who’s giving the advice? Look for credentials and relevant expertise. That said, keep in mind that credentials alone don’t make every health claim correct. Fact check. “And even when information is accurate,” says London, “it still may not be the right information for you . Talk to your doctor or make an appointment with a registered dietitian to help you clarify before you start something that you think could impact your health long-term.”
Are they selling something? While this doesn’t have to automatically invalidate advice, financial relationships do matter when evaluating it.
What’s being promised? Absolute language (think: words like “never” and “toxic”) or claims that a good can destroy or transform health are major red flags.
Where’s the evidence? A screenshot of a study is not enough. A creator will ideally present a balanced reflection of the body of evidence rather than cherry-pick to back up their claim. “If it sounds too extreme or too good to be true,” says Amer, “put on your detective hat and do some additional research before just believing what you see as you scroll.”
How is the content impacting your relationship with food ? How does it make you feel? Gans recommends checking in with yourself about whether the content is actually helping you eat better or simply making you more anxious about food.
Feller also encourages looking beyond social media for health information. “I recommend that consumers take everything, literally everything, with a grain of salt. Ideally, seek out nutrition- and health-related content from reliable, credentialed sources that are committed to critical thinking. We are in an era where reading is becoming a lost art. I encourage folks to read the source material, become acquainted with red and green flags, and be discerning.”
The problem isn’t that people are learning about nutrition on social media—it’s that very different types of information into the same feed. While there are can huge differences in the credibility and usefulness of these posts, to viewers (and the algorithm), they’re all just engaging pieces of content, which can lead to confusion and overwhelm.
Social media has the potential to expand users’ culinary worlds, connect them with experts, build community and make healthy eating feel approachable. However, in a digital ecosystem where these feeds are designed around what grabs attention rather than individualized health, this can cause people to adopt unhealthy views and habits.
Rather than automatically allow social media content to dictate what does and does not deserve to be on your plate, approach food-related content with curiosity and use it to inspire further thought and investigation.
Remember, says London, “Something you see online can be completely accurate and still not be right—or even particularly useful—for you . Your medical history, diet history, food preferences, budget, lifestyle, cooking skills, interest in meal prep and about a million other factors determine whether a recommendation makes sense in your actual life.”
