Studying Dietetics in the Age of TikTok Nutrition: How Students Learn to Separate Evidence from Aesthetics
As a college student on the internet, I, like many of my peers, am often at the mercy of influencers for lifestyle advice. One of the most common themes on my feed relates to fitness, health, and diet. Viral “What I Eat in a Day” videos appear endlessly, alongside recommendations for detoxes, the carnivore diet, juice cleanses, and other trendy approaches. The volume of content is overwhelming, and as a student studying dietetics, it can feel even more convoluted.
Balancing academic learning with social media messaging is a unique challenge. I may spend the day learning research-based principles in class only to end the night scrolling through videos that contradict everything I was taught just hours earlier. It doesn’t stop at social media, either. Friends and family often share new fad diets they are trying because a favorite TikToker promoted them. The driving force behind this culture is the sheer amount of misinformation online, paired with widespread confusion about food and a growing desire, especially among young people, to find the quickest route to aesthetic goals. Even with a strong academic foundation, I still occasionally fall into the trap of watching “What I Eat in a Day” videos and feeling comparative or discouraged.
One of the biggest lessons dietetics students can draw from today’s internet culture is that this digital environment is not going away and it will likely continue to shape how people view nutrition. The constant flow of conflicting advice, non–health professionals offering prescriptive guidance, and overly restrictive “1100-calorie” diets is a reminder that, as future practitioners, we must meet people where they are. It is essential to approach this landscape with empathy and an awareness of the misinformation that shapes many individuals’ beliefs about food.
For my peers and family members, I find comfort in being able to share what I’ve learned through my education and help clarify some of the confusion. A few strategies I often recommend for avoiding a spiral of online nutrition misinformation include:
1. Check credentials. Look for RDN, LDN, or clinical degrees such as MD, DO, PA, or NP. In research-focused contexts, credentials like MS or PhD matter. If these are absent, proceed with caution.
2. Be skeptical of absolute language. Phrases like “Never eat,” “This is toxic,” or “The ONLY way to lose weight” are red flags.
3. Consider what the influencer gains. If someone is selling a supplement, promoting a program, or relying on shock value for views, their advice may not be objective.
As dietetics students, we are learning not only how to interpret research, but also how to navigate the modern digital world. By staying grounded in science and sensitive to the realities of online culture, we can better support the communities around us and contribute to a healthier, more informed conversation about food.
