Overview of Plant Paradox and Carnivore Diet Claims
The podcast episode discusses the conflicting and contradictory nutrition information inundating the world, highlighting extreme dietary beliefs from vegan to carnivore diets. Various dietary ideologies and the impact of different diets on health are debated. The podcast explores the claims made in the book 'The Plant Paradox' about lectins and their alleged negative effects on health.
Nutritional Adequacy and Health Risks of Carnivore Diet
The nutritional inadequacy of a purely carnivorous diet is emphasized, revealing deficiencies in essential vitamins and minerals. Anecdotal reports of individuals not feeling well on the carnivore diet are mentioned. The potential risks and downsides of consuming solely animal-based foods, including the impact on cardiovascular health, are highlighted.
Scientific Accuracy of Carnivore Diet Claims
The scientific accuracy of carnivore diet claims is questioned, with a focus on the lack of evidence supporting extreme dietary restrictions and the distortion of scientific facts. The discrepancy between anecdotal reports and scientific evidence is discussed, highlighting the importance of objective scientific studies in assessing dietary recommendations.
Impact of Plant Foods on Health Outcomes
Contradictory claims on the benefits of plant foods are addressed, with a review of studies linking higher consumption of unrefined plant foods to improved health outcomes. The potential health benefits of specific plant compounds, such as flavonols from cocoa, are explored, contrasting claims made in the carnivore diet context.
Lectins and Chronic Diseases
Consuming lectins from certain plants, particularly legumes and grains, may lead to inflammation and tissue destruction, potentially contributing to various chronic diseases. Cooking methods like soaking and pressure cooking can significantly reduce lectin concentrations in foods like kidney beans and whole grains, making them safer for consumption.
Concerns About Lectin Toxicity
While there is evidence supporting lectin toxicity and the need to avoid large amounts of certain lectin-rich foods, like kidney beans and tomatoes, it is essential to prepare these foods properly to minimize lectin content. Small amounts of lectins remaining after cooking may still elicit digestive issues, but the overall health benefits of these foods outweigh potential risks.
Balancing Scientific Evidence and Dietary Choices
Navigating dietary claims and complexities regarding lectins requires a balanced approach. The scientific evidence emphasizes the health benefits of consuming lectin-rich foods when prepared correctly. Individual responses to lectins may vary, suggesting a targeted approach for people experiencing health issues related to lectin consumption. It is crucial to consider the broader context of scientific research and individual health profiles when making dietary decisions.
In this episode, I’m re-releasing an episode with Dr. Stephan Guyenet and Dr. Mario Kratz, two impressively experienced nutrition researchers with a wide range of expertise, about their organization Red Pen Reviews, a non-profit dedicated to publishing unbiased, scientifically accurate reviews for current nutrition books hitting the market.
Today, we focus on two popular but controversial books—Dr. Steven Gundry’s The Plant Paradox and Carnivore Code from Dr. Paul Saladino.

In this podcast, Dr. Guyenet, Dr. Kratz, and I discuss:
How difficult it is to parse out accurate versus inaccurate and biased information and the regulated and systematic role of Red Pen Reviews in clearing up the confusion
The 3 focus areas Dr. Guyenet and Dr. Kratz use to score the books they review and the importance of each
How the health claims made in Carnivore Code compare to research AND anecdotal reports of people eating the diet…and how the main claim that humans evolved to be carnivores compares to evolutionary evidence
Possible downsides or even dangers of the carnivore diet and if these caveats are discussed in the book
The full truth of the claim that elevated LDL is not a cardiovascular concern if a person has excellent metabolic health
Does a nose-to-tail carnivore diet provide all the nutrients you need each day?
The Plant Paradox’s primary claim that certain plant lectins lead to approximately 50 diseases…plus, what a lectin actually is!
What current research tells us about lectins triggering leaky gut, inflammation, and autoimmune disease
The health status of people who eat large amounts of lectin-rich legumes, tomatoes, and other nightshade vegetables
Could lectins and other plant foods be stressful BUT ALSO beneficial at the same time?
Practical ways to evaluate the nutrition information you take in every day so you can more easily consider what’s accurate and what’s likely not
