Balancing Autoimmune Nutrition: Evaluating the Carnivore Diet’s Risks and the Protective Role of Plant-Based Foods in Personalized Care - 2025

Autoimmune diseases present complex, chronic conditions that often resist conventional treatments, prompting growing interest in dietary interventions. Among these, the carnivore diet—comprising exclusively animal-derived foods while eliminating all plant-based inputs—has gained popularity as a potential strategy for mitigating autoimmune symptoms. Advocates suggest this approach may reduce exposure to dietary antigens such as lectins, oxalates, and FODMAPs, thereby decreasing gut permeability, systemic inflammation, and immune activation. Clinical anecdotes and case series report notable improvements in patients with rheumatoid arthritis, lupus, and inflammatory bowel disease. However, scientific validation remains limited, and long-term health consequences are not well understood. While the diet's high nutrient bioavailability, low processing, and elimination of potentially pro-inflammatory compounds may benefit some individuals, critical concerns persist. These include the absence of dietary fiber, plant polyphenols, and prebiotics essential for maintaining gut microbial diversity and immunological tolerance. Moreover, excessive intake of saturated fats and restricted dietary variety may pose risks for metabolic dysregulation and micronutrient imbalances. Personalized adaptations—such as incorporating low-FODMAP vegetables or low-oxalate leafy greens—can potentially bridge therapeutic benefits with nutritional adequacy. Ethical and sustainability considerations further complicate adoption. A heavy reliance on industrial animal agriculture contradicts environmental goals, though local and regenerative food systems may offer a compromise. This review evaluates current evidence and argues for a cautious, individualized approach. Rather than promoting extreme dietary exclusion, a monitored, phased, and adaptive plan—guided by clinical biomarkers and patient response—offers a more balanced path forward in the nutritional management of autoimmune diseases.

This is a Review, which is a fancy way of saying expert opinion. It does a fairly good job of surveying the current positives of carnivore - while repeating only short term evidence, caution each and every time.

It's a good challenge piece, and outlines the arguments against carnivore as well. The authors have a tremendous bias (The Journal : Advances in Herbal Research)

  • The author is 100% onboard with the plant based paradigm (the bias is in the title), the fact they begrudgingly acknowledge the benefits of carnivore on such a massive scale (i was surprised they did it at all) in the literature speaks to the power of the signal.

    I find it humorous that even after talking about the absolute benefits, they always have to do the what-about-ism pivot and figure out a way to add plants in.

    The protocol they propose is - Take a unhealthy patient, Get them healthy with carnivore, Add plants back in until they get unhealthy again then back off a smidge. Now, that is fun mental gymnastics!

    This paper is a Hamiltonian walk around every carnivore myth and fear you have heard about along with every virtue of every plant. It's good reading.

    The author does not take the time to make the distinction between association and causation when talking about benefits of pbf, but they do talk about the possible reasons carnivore is nutritionally complete (they even cover vitamin c glut-4 competition with glucose). Most of their protocol is deviating the diet for associated benefits of plants, they don't use solid end points and focus on intermediate biomarkers when promoting pbf. Looking at how they assume the reduced association of the FODMAP diet is clinically relevant, they didn't apply the same level of critical thinking to their target interventions that they are applying to carnivore.

    They are 100% correct that long terms studies are lacking - they are! More research is required - It is!
