Research Reflection Inspired by World Vegan Day

Research Reflection Inspired by World Vegan Day

Regardless if  you are vegan or not,  you may have already considered  how  your  diet influences the planet and all the  organisms living  on it—especially now,  when we are faced with environmental disasters and persistent news about animal cruelty.

However, the discourse about veganism is complex. As a researcher in the field of eating disorders, I am inclined to critically engage with any diet that includes rigid food restrictions. I recognize the many advantages of a vegan diet, but I would also like to raise awareness  for the potential challenges of  veganism that need to be assessed on an individual basis.   

So, what is a vegan diet?   

The Vegan Society (founded in 1944!) describes  veganism as a “[…]  philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose […].  In dietary terms, it denotes the practice of dispensing with all products derived wholly or partly from animals.” (1).  The  NHS  describes  a vegan diet as wholly plant-based, excluding all animal products such as meat,  dairy, and eggs (2).   

Not everyone who is vegan practices veganism the same way  (some people still eat honey or wear leather boots)  so for the purpose of this blog post, I will mainly focus on a vegan  diet.  As a psychologist and anthropologist, I am fascinated by  the  conscious choice to not only  consider what is accessible or palatable, but what is  ethical  to consume.  If we have managed to evolve into  self-reflective, inventive  human beings, how can we not find alternatives for the ways that we are exploiting the planet?   

However, veganism is not only associated with action against animal cruelty and environmental benefits. The Vegan Society states:  “Going vegan is a great opportunity to learn more about nutrition and  cooking and  improve your diet. Getting your nutrients from plant foods allows more room in your diet for health-promoting options  […]” (3).  In  a society where food options are almost unlimited, we  are able to  look at food  from an optimization perspective. Therefore, we have the luxury to ask:  how can we eat  better? Health being one possible motivation behind a vegan diet,  evokes another question:  what is  a healthy diet? A question that I have studied for the last two and a half years.   

Talking about my research interests is usually associated with one of two reactions: awkward  silence  or strong opinions. More than once somebody has asked me “And what is your research about?” while biting into a cheeseburger,  only to put it down quickly once I say the words “I study obsessive healthy eating”. Suddenly people become self-aware. Are they eating healthy enough? Is there such a thing as “too healthy”? How can something be bad if it is meant to be healthy? Health has become part of our moral system. Health is good.  Therefore,  we are ashamed if we are not healthy. If we are eating a cheeseburger, we do not want to be reminded of health, because momentarily we are doing something “bad”. We enjoy it, but do not want to think about it too much.   

“Healthy eating”, on the other hand, is  perceived as  a good thing. The right thing to do. It makes us look better  and live longer. But…what  is  a healthy diet?  Many guidelines for healthy eating are continuously being published (and revised).  However, most people from industrial countries do not meet outlined recommendations for healthy eating (4).  In preparation for my PhD,  I have read studies about the  use of the  Glycaemic index,  the benefits of a Mediterranean diet, and the health of vegetarian Seventh Day Adventists. The more I read, the less I was convinced that there is such a thing as  one  healthy diet.  Clear benefits were usually only found for eating a  variety  of foods while moderating the intake of anything but fruits and vegetables.   

Not knowing what a healthy diet  looks like complicates my research project. For example,  I have yet to meet a physician who endorses a vegan diet, but I have read multiple studies that see  well-planned  vegan diets as beneficial for  ones’ blood pressure, heart disease and  cancer risk.  ‘Well-planned’ in this case means that  supplements or fortified foods are  needed  to avoid  iodine, calcium, vitamin D and B12 deficiencies (5).  Having said this, ‘health’ is often reduced to our physical  well-being. As a psychologist studying obsessive healthy eating, I  have to  go further. How ‘healthy’ are our eating behaviours for our  mental  well-being?   

Meat and dairy consumption are  currently  part of the social norm in Western  societies (6), which might mean  vegans have  less options available at social gatherings involving food.  Food restrictions, in the broadest sense of the word, are  therefore  part of being vegan.  This does not mean that  being vegan  is associated with the same kind of restrictions as in disordered  eating but  focusing  on what can or cannot be eaten might pose a problem for some people.  A recently published large-scale study conducted in Germany (2020) (7)  found a significant association between adhering to a vegetarian or vegan diet and the display of disordered eating behaviours. However, the  authors  conclude that the  causal relationship is unclear  (it could be a way of maintaining an eating disorder, the reason for developing an eating disorder or coincidental, as the samples of vegan participants are usually very small).   

So, what could the relationship be between veganism and disordered eating?  As outlined by the Vegan Society, potential motivations for  becoming  vegan involve ethical, environmental and health considerations.  At the same time, having a history of an eating disorder or being inclined to  diet for weight loss reasons need to be taken into consideration when assessing the motivations behind veganism.  Vegan diets have been associated with a higher risk for  dysfunctional food preoccupations (8), only  if  health  was an important motivation for becoming vegan.  This could be related to the fact that we are still struggling to define “healthy eating”,  with current definitions being too extreme.  Furthermore, a  vegan diet requires conscious planning in order to avoid malnutrition, which  is why it might lead to an extreme fixation on food.   

It is beautiful to see that more and more people think about how to make this planet a better place. However, we should not forget that  ‘health’ is a concept we have created and being healthy could mean very different things for different people.

If you decide to become vegan, be aware of why you are motivated to do so  as you will need to do your  research on how to supplement the foods you are not eating anymore. If this is causing you any distress, talk to someone you trust and think about getting  professional  help to balance your aspirations to change with your own well-being in every sense of the word.
