Nutrition myths in the vegan community | Ginny Messina

Listen Now

In Episode #217, I sit down with dietician Ginny Messina to address common nutrition myths about the vegan diet.

“It is not difficult to meet nutrient needs on a vegan diet, but it is not intuitive either.”

With an abundance of nutrition “information” presented to us any time we use social media, it becomes difficult to identify whether a claim is fact or fiction. Misinformation is a common issue across all patterns of eating — including a plant-based diet — and understanding the full picture is incredibly important to ensure health and longevity. Ginny Messina joins me to address common nutrition myths about the vegan diet, providing a broader view that will help plant-based eaters make sense of nutrition needs.

Ginny Messina, MPH, RD, is a dietician, public health nutritionist, and animal rights advocate. She is the author of eight books on veganism, and a founding member of the Vegetarian Nutrition Dietic Practice Group in the US. Amongst many other achievements, she writes and speaks about vegan nutrition, preventing ex-vegans, and body positivity. Ginny is one of my go-to recommendations for people seeking more information on vegan diets and brings an incredible wealth of information to this episode.

“Veganism is not a guarantee that you’re going to be healthy, not a guarantee that you’re going to be thin, and not a guarantee that you’re not going to die. Even vegans die.”

In this episode, we address 16 myths that could have negative health implications if followed. Ginny Messina speaks to the limitations and strengths of the evidence that we have, provides recommendations for optimal health, and discusses the ethical reasons for making diet choices. We also cover supplementation, concerns about vegan diets, and how to evaluate claims you find online.

Specifically, we discuss:

  • Greatest Risk to Vegans [1:39:40]
  • Outro [1:43:55]

As Ginny Messina says in this episode, presenting and understanding all the evidence does not dilute the message of veganism, but rather promotes longevity and the best health outcomes. I have great respect for Ginny’s work, and her transparency on the limitations of the evidence to build the most comprehensive, evidence-based approach possible.
