The carnivore diet, veganism and nutrition misinformation | Dr Alan Flanagan

Listen Now

In Episode #227, I sit down with Drew Harrisberg and Alan Flanagan, PhD to discuss the carnivore diet and veganism, assessing many of the popular claims made by health and nutrition “influencers”.

“The primary determinant of our health now, of health generally, is not outlier behaviours. It is diet and lifestyle and exercise — and if we go one step back from that… the biggest driver of health or ill health in society is all of these kinds of socioeconomic and environmental factors.” – Alan Flanagan, PhD

In the current social media climate, it is crucial that we develop the skills necessary to analyse the validity of nutritional claims. During this week’s episode, The Proof welcomes two fan favourites to the show to cover a broad scope of topics in a well-rounded discussion, uncovering the reasoning behind a number of these claims and informing listeners on how to assess them.

Alan Flanagan, PhD is a researcher and science-based nutrition educator. He recently featured on the show in Episode #225, analysing the health implications of dairy consumption. Drew Harrisberg is exercise physiologist, sport scientist, and diabetes educator. Both guests bring extensive knowledge and an educational, research-backed lens to this conversation, placing public health at the forefront.

“You can feel good, but what’s going on inside that you can’t see, or measure… is completely different to the subjective experience.” – Drew Harrisberg

This episode is absolutely packed with information, offering you tools for assessing individual claims for validity and misinformation. We discuss Big Pharma, social media censorship, the carnivore diet, and vegan protein intake.
