Social media platforms like TikTok have become major sources of nutrition and health advice for Millennials and Gen Z. With the ease of sharing and consuming content, viral trends can quickly gain traction and influence eating habits. From unique drinks to unconventional diets, these trends often promise quick results, attracting a large audience eager to try the latest health fads.

MyFitnessPal conducted a survey with 2,000 participants across the United States, Canada, the United Kingdom, and Australia to understand the impact of TikTok on nutrition choices. The survey revealed that 87% of Millennials and Gen Z users turn to TikTok for health advice. Additionally, 57% of these users frequently adopt nutrition trends they encounter on the platform, with 67% trying at least one trend a few times a week.

The survey identified several fad diets gaining popularity on TikTok, including detoxing, foods that burn stomach fat, and liquid cleanses. Gen Z participants are more inclined to try trends like chlorophyll water, while Millennials often experiment with detox diets, the cabbage soup diet, and the Carnivore diet. Unfortunately, many of these diets lack scientific backing, raising concerns about their safety and effectiveness.

Despite the lack of scientific support, 30% of survey respondents have attempted these fad diets. Alarmingly, 31% have experienced adverse effects from following these trends. Health risks may include nutritional deficiencies, digestive issues, and other negative impacts on overall well-being, highlighting the need for caution when adopting such diets.

With the growing reliance on social media for health information, enhancing digital health literacy is crucial. Understanding the credibility of sources and the science behind trends can help individuals make informed decisions about their nutrition. Experts like Katie Keil from MyFitnessPal emphasize the need to follow trusted sources, such as registered dietitians and medical professionals, to ensure accurate and safe health advice.

Positive findings from the survey show that Gen Z trusts content shared by qualified registered dietitians more than unqualified influencers. To bridge the knowledge gap, MyFitnessPal and Dublin City University have developed a resource to help individuals identify nutrition inaccuracies on social media. This tool serves as a checklist to promote digital health literacy, empowering users to make better-informed food choices.

The influence of social media on nutrition trends is significant, especially among younger generations. While platforms like TikTok can spread valuable information, they also pose risks when promoting unverified diets. By improving digital health literacy and relying on expert guidance, individuals can navigate the digital landscape more safely and achieve their health goals effectively.
