The vegan diet has gained immense popularity. A dietary lifestyle that once seemed extreme, picky and difficult to cater for has become one of the hottest topics in heath and nutrition right now. There is an onslaught of persuasive vegan media, vegan critics have gained more of a louder voice, and with tenacity the campaign is really quite intense.
Let’s be clear. I’m not anti-vegan. I am an omnivore and I’m not a passionate meat eater either. I don’t eat much meat and vegan cook books make up the majority of my collection. I am however concerned with some of the veganism claims floating around that are based on pseudo-science, skewed claims and the judgements that scoff at anyone who isn’t following a vegan diet because we’re so unenlightened and stupid for not seeing the light.
A lot of the momentum for veganism was gained on social media; social media influencers have a massive power over our health and well-being choices (Byrne et al, 2017). This is important in relation to influencing public health amongst the general population with influencers often having more impact than traditional advertising campaigns. It seems that fruit and veg finally have some momentum to compete with food manufacturers. One study found that 41% of participants agreed that social media influencers motivated them to make healthier food choices sometimes, and for 32% of participants the motivation to eat healthier overall (Byrne et al, 2017). This news could only be bloody brilliant right? Finally, we have an effective way of influencing the nation’s diet for the better?
Uhhhmmm, not always. There is a downside to the influence of social media trendsetters. A big proportion of influencers are not qualified dietitians or nutritionists (Byrne et al, 2017), which is important when misleading nutritional information is being shared (Byrne et al, 2017). This makes the dietary choices they’re recommending potentially health damaging as they advocate choices such as gluten-free as a healthier choice for those without coeliac disease, and diets that can include eliminating whole food groups and lead to nutritional deficiency (Byrne et al, 2017).
I’m not saying you can’t have a complete diet whilst being vegan, but you do need to spend effort covering all of your bases to prevent malnourishment (Cramer et al, 2017). A main and legitimate concern for those following a vegan diet is bone health over time. Insufficient intakes of calcium, vitamin D, Vitamin B12, zinc and n-3 fatty acids can lead to a higher chance of developing osteoporosis and fractures (mangano and tucker, 2017).
I have many burning questions about veganism which I will be exploring in a series of posts including topics such as:
- The role of supplements
- Maintaining bone health in the long run
- Whether vegan really is the healthiest option
- Where pseudo-claims are coming from
- Whether the reason for being motivated to follow a vegan diet affects compliance over time
- Endurance training
- Environmental impact of diet and lifestyle choices
- Eating disorders and veganism
- Mood and veganism
Let’s go on a journey of discovery and see what science says about veganism. If you have any specific topics you’d like to read about you can comment or email me at firstname.lastname@example.org
