The pandemic has accelerated the ongoing transformation of higher education, pushing institutions
In an era inundated with information, the ability to think critically and discern fact from fiction has become a quintessential skill. This is especially true when it comes to nutrition. These days, we are often bombarded with information regarding nutrition, much of it contradictory. This can lead people to take on diets and lifestyle changes that may not actually be what their body needs, and could actually be harming them. Therefore, it’s up to health science educators to debunk health myths and teach not just the facts, but how to think critically in human nutrition courses.
The Landscape of Nutritional Myths
In order to start debunking nutrition myths, let’s back up a little. What are some of the biggest nutritional myths that we hear, and where did/do they come from? We’re sure that you’ve heard of these at some point in your life:
“Carbs are the Enemy”: This myth simplifies carbohydrate — an essential macronutrient — as the adversary of a healthy diet. It has prompted many to adopt restrictive and unsustainable eating patterns, leading people to avoid foods that could actually be healthy (and tasty!) In reality, carbohydrates serve as a primary source of energy for the body, and they come in various forms, including simple and complex carbs. Proper understanding of carbohydrates, including concepts like glycemic index and complex carbohydrates, is crucial for making informed dietary choices and maintaining long-term health.
“Detox Diets Cleanse the Body”: Detox diets are often marketed as quick solutions to eliminate toxins from the body. These diets typically involve short-term, highly restrictive eating plans (i.e. a juice cleanse) or detox supplements. Detox diets often lack a solid scientific foundation and may not provide the benefits they claim, leading to skepticism in the scientific community and among nutrition experts.
“All Fats are Bad”: This myth suggests that all types of dietary fats are detrimental to health. It has caused widespread confusion, leading some individuals to avoid all fats, even those that are essential for our well-being. Understanding these differences is crucial because certain fats — like unsaturated fats found in sources like avocados and nuts — play a vital role in maintaining overall health.
How Nutritional Myths Spread
So, where did these generalized nutrition advice even come from? Well, it’s a combination of a number of things. Once upon a time, fad diets were often propagated by celebrities and self-proclaimed wellness gurus, and breached into the general population via magazines, books, and other print media.
Nowadays, social media allows these claims to reach a wider audience that much faster. And, according to Science Direct, “…this access provides entry points for inaccurate information from unqualified individuals. This emergence of mistruths can create a momentum powerful enough to shape perceptions of food, nutrition, and diets, and the scope and scape of this problem and its impact on the public and public health are still largely unknown.”
The Role of the Educator in Addressing Myths
The future of debunking nutrition myths lies in the hands of health science educators, who face the challenge of students with varying preconceived notions about nutrition best practices. To address this, educators must ensure that students have a strong grasp of nutritional basics, starting with fundamental topics such as macronutrients, micronutrients, and dietary guidelines. This foundational knowledge equips students with the essential tools for critical evaluation.
In effectively debunking myths, educators incorporate case studies of popular diet trends into their curriculum, prompting students to critically analyze these trends in light of established scientific principles. This approach not only encourages students to question prevailing notions but also hones their skills in evidence-based thinking and scientific inquiry, essential for their future careers in the field.
Techniques to Encourage Critical Thinking
The ability to think critically when it comes to human nutrition is possible for all of us, but it’s not always so easy to teach. This is why it’s vital that human nutrition courses foster critical thinking, so students have the tools to answer questions effectively. Educators can encourage critical thinking by instilling essential techniques:
Teaching Students to Evaluate Sources: Students should learn how to distinguish between credible scientific studies, peer-reviewed journals, and anecdotal evidence, and their non-credible counterparts. This discernment ensures that they base their dietary knowledge on substantiated information rather than hearsay.
Encouraging Debate and Discussion: In the spirit of intellectual curiosity, students are encouraged to engage in debates and discussions. They explore and analyze nutritional myths, employing their research skills to either defend or debunk these myths. This interactive approach not only bolsters their critical thinking abilities but also fosters a dynamic learning environment where diverse perspectives are valued.
Real-World Applications – Making it Relevant for Students
Human nutrition courses bridge the gap between theory and practical application by exploring ways that this knowledge can be applied in real-world settings. In order to do this, there are some strategies that educators and institutions of higher learning in general can implement to enhance student learning:
1. Invite Guest Speakers
By inviting guest speakers, experts can come and share their experiences and expertise, shedding light on the tangible effects of misinformation on health and well-being first-hand. This direct interaction connects students with professionals actively working to debunk myths and promote evidence-based nutrition.
2. Assign Students Meaningful Projects
No one likes homework, but giving assignments to students that are designed to challenge students to put their knowledge into practice can help make these concepts more relevant. One idea is to task students with researching and debunking a popular nutrition myth using credible sources, which can be done individually and/or in a group project setting. Make it relevant by asking them to use something they’ve heard on a social media handle they follow. You could also turn it into a debate.
3. Connect Nutrition Topics to Current Events
Another way for educators to help debunk nutrition myths is to connect them to what’s going on in the world. Educators should consider utilizing real-time examples, drawing from diets and health claims that are currently trending in the media to teach students how to determine what’s actually true. By analyzing these current events, students are better prepared to navigate the ever-shifting terrain of nutrition misinformation, especially when they start practicing as health professionals.
Benefits of Debunking Myths in the Classroom
There are many advantages of debunking nutrition myths within the classroom setting, but here are some of the most important ones:
- Establishing a Safe Space: Students come from all different backgrounds which can influence what nutrition ideas they are familiar with. Inviting students to discuss these in a classroom setting can help students feel safe knowing that their peers may also come to the table with what may be potential nutrition myths as well. Of course, it is up to the educator to make sure the conversation is actually one that is safe and nonjudgmental.
- Empowering Students: By equipping students with the knowledge and skills to scrutinize and debunk myths, human nutrition courses empower them to make informed nutritional choices in their personal lives, which can translate over to the classroom environment and ultimately, their professional practice.
- Preparing Future Health Professionals: For students planning careers in health-related fields, the ability to separate science from pseudoscience is extremely important. Human nutrition courses play a pivotal role in preparing the next generation of health professionals with standardized, evidence-based knowledge and practice.
- Building Trust in Established Science: By teaching students how to critically evaluate claims and effectively source accurate scientific information, it helps to foster a larger community that holds trust in established nutritional science across the board. This trust is essential for fostering a society that values the expertise of nutrition professionals over sensationalism and pseudoscientific claims.
Why It’s Necessary for Educators to Debunk Nutrition Myths
Misinformation in nutrition has become an unfortunate byproduct of our rapidly spreading media. It’s why health science educators bear the responsibility of equipping their students with the strategies and critical thinking skills necessary to debunk not only prevalent nutrition myths but also those likely to emerge in the future. This approach is essential for fostering a generation that feels empowered to dissect nutrition trends, discern the truth through evidence-based sources, and adhere to best practices. Ultimately, it paves the way for a healthier population in the years to come.
