Don’t Be Fooled: Recognising Delusions in the Field of Applied Nutrition

Applied nutrition science is an important field that has a significant impact on health outcomes. However, there are many delusions and misconceptions about the space, which can lead to confusion and misinformation. 

And in this article, we will explore some common misconceptions regarding applied nutrition science and provide insights to help set the record straight. So let’s get started!


DELUSION #1: Trending diets backed by research are the most effective.

The truth: Fad diets and trending diets often promote extreme or restrictive eating patterns that may not be effective at all or sustainable in the long run. While some of these diets may promise short-term benefits, they can also harm one’s overall health, carry adverse effects and contraindications, and eventually lead to health issues and nutrient deficiencies.

As a nutritionist, it’s your responsibility to guide your clients towards a sustainable and sensible approach to nutrition based on the best available evidence.

DELUSION #2: The latest studies can be considered the best available evidence.

The truth: While new studies can offer valuable insights and add to the body of scientific evidence, they should not be taken as the final word on a particular topic. Scientific research is an iterative process, and individual studies can have limitations or flaws that should be considered when interpreting their findings. 

Furthermore, findings from a singular study may not be applicable to a broader population. It is important for nutritionists to assess the entire body of scientific evidence on a topic and use their clinical judgment when making recommendations to clients.

DELUSION #3: Applied nutrition science is risk-free.

The truth: While nutrition research has advanced significantly in recent years, there is still a lot of conflicting information and misinformation out there. It’s important to be sceptical of sensational claims or promises of quick fixes. 

As a nutrition professional working with clients, you have the responsibility to base your recommendations on the best available scientific evidence. This involves making sure that you evaluate the risks and benefits of each strategy you put forward, including any potential adverse effects and contraindications for specific circumstances.

DELUSION #4: Nutritionists should only focus on what clients eat.

The truth: While diet quality is a crucial component of overall health and well-being, it is not the only factor. Other lifestyle factors, such as stress levels, sleep patterns, and physical activity, also play vital roles in how we respond to food.

A broader approach to nutrition considers the whole person, their health practices, and their unique circumstances. By addressing a variety of aspects of nutrition and wellness, you can help your clients get closer to their health goals much more efficiently.

DELUSION #5: One-size-fits-all nutritional advice works.

The truth: What works for one client may not work for another, and generalised nutritional advice may not be appropriate for everyone. Instead, nutrition recommendations should be personalised to each client’s unique needs, preferences, and circumstances. 

By taking into account individual factors such as age, gender, activity level, health status, and food preferences, you can develop a nutrition plan confidently that maximises your client’s chances of success.

DELUSION #6: All nutrients are safe and beneficial.

The truth: As a nutritionist, it’s important to recognise that while many nutrients and supplements can offer significant health benefits, they might also have adverse effects when taken in excessive amounts (such as vitamin A toxicity) or in combination with certain medications. 

To ensure your client’s safety and well-being, it’s essential to work collaboratively with them and their healthcare providers to determine the most appropriate supplements and nutrient doses for their unique needs and health status. This way, you can help your clients avoid potential negative outcomes and achieve optimal health outcomes.

DELUSION #7: Nutritional advice should only be based on scientific evidence.

The truth: While considering the body of evidence behind specific recommendations is important to mitigate the risk of wrong advice, nutritionists need to look at the whole person as well. Understanding your client’s needs, preferences, circumstances, lifestyle practices, and other factors from your communication with them can better inform your nutritional advice and help develop personalised nutrition plans that are safe, effective, and motivating.

Research may seem remarkable on paper, but it can be impractical and difficult to implement. That’s why an ongoing dialogue with your client is key in ensuring they get the most effective guidance possible at every step. 

DELUSION #8: Applied nutrition science is limited to public health.

The truth: This arises from a misunderstanding of the scope and applications of nutrition science. While public health nutrition is a critical area within applied nutrition science that focuses on improving the health and nutrition of entire populations, applied nutrition science encompasses a wide range of applications beyond public health. In fact, much of applied nutrition science is focused on working with individuals to help them achieve their health and nutrition goals through evidence-based dietary and lifestyle interventions. 

Nutritionists who work with private clients use applied nutrition science principles to tailor nutrition plans to their clients’ unique needs and circumstances, taking into account factors such as age, gender, medical history, dietary preferences, and lifestyle habits.

DELUSION #9: Results are guaranteed when you apply nutrition science rigorously.

The truth: Many people assume that by following the methods from a scientific study, they will experience significant and immediate improvements, just like the study participants did. However, the reality is that the results of nutrition interventions can be highly variable and may depend on a wide range of factors, including an individual’s baseline health status, genetic makeup, lifestyle habits, and environmental influences. 

While some nutrition interventions may lead to dramatic improvements in health outcomes, such as weight loss or improved blood sugar control, others may have more modest or no effects. In fact, some nutrition interventions may even have negative effects if they are not tailored to an individual’s unique needs and circumstances. Moreover, the field of nutrition science is constantly evolving – what we know about nutrition today may be different tomorrow as new research is conducted and findings emerge.

As a nutritionist, it’s important to help your clients understand the limitations of nutrition interventions and to set realistic expectations for what they can achieve through dietary and lifestyle changes. By taking a personalised and evidence-based approach to nutrition counselling, you can help your clients achieve meaningful improvements in their health and well-being over time while helping them avoid the pitfalls of fad diets or quick fixes.

DELUSION #10. All nutritionists have the same know-how.

The truth: There is a misconception that all nutritionists have the same level of education and training. In reality, the competencies of nutritionists can vary significantly depending on their educational background, training, and experience. This variation can have a substantial impact on the quality of the nutritional advice and support provided to clients.

In other words, a nutritionist’s level of education, training, and experience can significantly impact the quality of the nutrition advice and support they provide. Therefore, it is crucial for nutritionists working with clients to ensure they are equipped with the latest evidence-based research and stay up-to-date with the recent developments in the field, and continually grow their knowledge and skills through ongoing education and training. This will ensure that clients receive the most current and accurate information and guidance, ultimately helping them get closer to their health goals safely and effectively.


In conclusion…

As a nutritionist, it’s important to understand that applied nutrition science is a critical field that can have a significant impact on health outcomes. However, there are many delusions and misconceptions that can lead to confusion and misinformation. By recognising and addressing these, you can focus on providing safe and evidence-based advice to support your clients better. 

It’s crucial to understand that nutrition interventions are not risk-free and should be personalised to each person’s unique needs, preferences, and circumstances. It enables you to help your clients achieve meaningful improvements in their health and well-being over time.
