The Gundry Philosophy on Protein
Dr. Steven Gundry, a former cardiac surgeon and author of The Plant Paradox and Unlocking the Keto Code, offers a unique and often controversial perspective on dietary protein. His recommendations are rooted in the belief that modern diets, particularly those high in animal protein and lectins, contribute to inflammation and chronic disease. Gundry's approach prioritizes quality, sourcing, and a much lower total quantity compared to mainstream nutritional advice. He emphasizes limiting animal protein and carefully selecting low-lectin plant-based proteins to support gut health and longevity.
The Recommended Daily Protein Intake
The 20-30 Grams per Day Guideline
According to a transcript from one of his lectures, Gundry has stated a daily protein intake goal for the average person that is dramatically lower than standard recommendations. He suggests that a typical 70-kilogram (150-pound) person only needs 20 to 30 grams of protein per day. This guideline is in stark contrast to the 60-70 grams that might be recommended based on the RDA for the same person. Gundry's logic centers on the idea that excessive protein, especially from animal sources, can lead to negative metabolic effects and is unnecessary for health.
Prioritizing Quality Over Quantity
Beyond the total number of grams, Gundry places significant importance on the source of the protein. He is not against protein entirely but is highly selective about which types are included in his diet plans. His recommendations emphasize sourcing grass-fed or pasture-raised animals, wild-caught fish, and pasture-raised, omega-3-rich eggs. For plant-based protein, he focuses on sources that are low in or free of lectins, such as certain nuts, seeds, and his own ProPlant Complete Shake supplement.
Animal Protein: A Cautious Approach
Gundry's diet is not strictly vegan or vegetarian, but it severely limits animal protein intake. This restriction is based on his concern about lectins and other compounds, such as Neu5Gc, found in certain animal products, particularly those that are grain-fed.
Limiting Meat Consumption
Dr. Gundry suggests limiting grass-fed, pasture-raised meat (including bison, lamb, beef, and wild game) to only once or twice per week. When consuming meat, he recommends limiting the portion size to just 4 ounces per day. For pasture-raised poultry like chicken and turkey, and wild-caught fish, his recommendation is 2 to 4 ounces per day.
The Importance of Sourcing
Gundry believes that the quality of animal products is paramount. He insists on grass-fed and pasture-raised options because they have a higher ratio of omega-3 to omega-6 fatty acids compared to grain-fed animals. This attention to sourcing is crucial for anyone following his diet to get the most nutritional benefit while minimizing what he considers potential harm.
The Role of Plant-Based Protein
For Gundry, the majority of one's protein should come from plant-based sources that are low in lectins. He incorporates a variety of ingredients into his diet plans to achieve this, including:
- Hemp products: Seeds, tofu, and protein powder are all endorsed.
- Selected nuts and seeds: Macadamia nuts, walnuts, pecans, hemp seeds, and sesame seeds are all on his approved list.
- ProPlant Complete Shake: Gundry's own supplement, which contains a blend of plant proteins, is designed to provide 10 grams of protein per serving.
Dr. Gundry's Protein Recommendations vs. Standard Advice
To understand the magnitude of the difference, consider the following comparison table. This illustrates how drastically Gundry's approach deviates from typical dietary recommendations from health authorities.
| Feature | Dr. Gundry's Recommendations | Standard Dietary Advice (RDA) |
|---|---|---|
| Daily Quantity | Very low, approximately 20-30g for a 70kg person. | 0.8g per kg of body weight (approx. 56g for a 70kg person). |
| Source Focus | Plant-based, low-lectin sources, specific pastured animals. | Variety of sources, including beans, legumes, and conventional meat. |
| Animal Protein Quantity | Severely limited (e.g., 4 oz grass-fed meat 1-2x/week). | Moderate intake is acceptable and encouraged for balanced nutrition. |
| Sourcing Importance | Extremely high; requires grass-fed, pasture-raised. | Less emphasis on specific sourcing; standard options are widely consumed. |
| Lectin Considerations | Central to the entire protein strategy. | Not considered a significant health concern for most individuals. |
Practical Tips for Following Gundry's Protein Plan
For those interested in adopting a Gundry-style approach to protein, here are some actionable tips:
- Swap Grain-Fed for Pasture-Raised: Choose pasture-raised eggs and poultry whenever possible. Instead of conventional beef, opt for grass-fed varieties and consume them sparingly.
- Prioritize Wild-Caught Fish: Focus on wild-caught fish, especially fatty varieties like salmon, which provide healthy fats and protein. These are preferred over farmed fish in his protocol.
- Use Plant-Based Sources for Volume: Increase your intake of approved plant-based proteins like hemp, walnuts, and macadamia nuts. These can help you feel satiated without relying on high volumes of animal protein.
- Incorporate Specific Supplements: If you struggle to meet your needs, consider a supplement like Gundry's own ProPlant Complete Shake to get a consistent, low-lectin protein boost.
- Prepare Foods Properly: For certain approved vegetables and proteins, proper preparation is key. Following Gundry's guidelines for cooking and, in some cases, peeling can help reduce lectin content.
Conclusion
For those following Dr. Gundry's recommendations, protein intake is less about hitting a high numerical target and more about selecting specific, high-quality, and low-lectin sources. He advocates for a significantly lower daily protein quantity—around 20-30 grams—compared to standard dietary guidelines, with a strong emphasis on plant-based proteins and very limited, carefully sourced animal products. This approach is central to his overall health philosophy, which focuses on mitigating inflammation and supporting gut health by avoiding harmful proteins and prioritizing nutrient-dense, clean foods. While controversial, his advice offers a distinct pathway for those seeking to alter their diet based on his principles.
