The Cornerstone of Gundry's Protein Philosophy: Avoiding Lectins
Dr. Gundry's dietary recommendations, famously outlined in his book The Plant Paradox, revolve around the concept that lectins—a type of protein found in many plants—are a primary cause of inflammation and chronic disease. His philosophy suggests that consuming foods high in lectins can disrupt the gut lining, leading to a condition he calls "leaky gut syndrome". Therefore, the search for the best protein source for Dr. Gundry and his followers is not about macro content alone but about finding high-quality options that are low in these problematic proteins. This necessitates a shift away from many conventionally celebrated protein sources, such as soy products, peanuts, and most beans and grains, to a more selective list of approved foods.
Dr. Gundry's Recommended Protein Sources
To replace high-lectin foods, Dr. Gundry provides an extensive list of compliant animal and plant-based proteins. His focus is on ensuring these sources are as natural and unprocessed as possible.
Animal-Based Proteins
When it comes to animal products, Dr. Gundry emphasizes sourcing to minimize exposure to lectin-containing feed. His recommendations include:
- Grass-Fed or -Finished Meats: This includes beef, bison, venison, lamb, and pork. The grass-fed distinction is crucial, as conventionally raised animals are typically fed grains high in lectins.
- Pasture-Raised Poultry and Eggs: For chicken, turkey, and duck, the emphasis is on pasture-raised options. The same rule applies to eggs, which should come from pasture-raised chickens to ensure a lower lectin content in their feed.
- Wild-Caught Fish and Shellfish: Wild-caught options like salmon, tuna, sardines, and crab are preferred over farmed fish, which can be fed soy and other high-lectin grains.
- Limited A2 Dairy: While most conventional dairy is out, Gundry permits small amounts of A2 casein milk products from European cows, or from sheep, goats, or buffalo.
Plant-Based Proteins
For those following a more plant-heavy approach, Dr. Gundry approves several lectin-friendly options:
- Hemp Protein: This is a cornerstone plant-based option, as it is a complete protein containing all nine essential amino acids. Hemp seeds can be sprinkled on salads or used in smoothies.
- Spirulina: This nutrient-dense blue-green algae is exceptionally high in protein, comprising nearly 70% by weight. It can be added to smoothies and juices in powder or tablet form.
- Barù Nuts: A lesser-known nut from Brazil, Barù nuts contain more protein per serving than most other nuts and are also rich in fiber and antioxidants.
- Flaxseed: A versatile source of plant protein, flaxseed is rich in omega-3s and fiber. Dr. Gundry recommends grinding the seeds just before use to maximize their benefits.
- Sorghum: This ancient grain is a lectin-free alternative to wheat and quinoa. It can be used as a flour for baking or found in pasta form.
- Pressure-Cooked Legumes: While most legumes are restricted, Dr. Gundry states that pressure-cooking can effectively eliminate their lectins, making them safe to consume.
Comparison: Gundry-Approved vs. High-Lectin Proteins
This table highlights the differences between Dr. Gundry's recommended protein sources and those he advises against due to their high lectin content.
| Protein Type | Gundry-Approved Sources | High-Lectin Sources (to Avoid) |
|---|---|---|
| Animal Products | Pasture-raised poultry, grass-fed beef, wild-caught fish, pasture-raised eggs | Grain-fed poultry and livestock, farmed fish, most dairy |
| Seeds | Hemp seeds, sesame seeds, flaxseed | Pumpkin seeds, sunflower seeds, chia seeds |
| Nuts | Walnuts, macadamia nuts, Barù nuts, pecans | Peanuts, cashews, almonds (with peels) |
| Grains & Legumes | Sorghum, Millet, Pressure-cooked beans | Wheat, rice, oats, corn, most beans and legumes |
| Supplements | Hemp protein powder, spirulina, isolated pea protein | Soy protein powders, whey protein (potentially A1 dairy-based) |
Incorporating Dr. Gundry's Protein Recommendations
Transitioning to a lectin-free, high-quality protein diet involves more than simply knowing the right foods. Here are practical steps to incorporate these principles:
- Rethink Meal Planning: Structure meals around approved protein sources and a "cornucopia of vegetables," such as leafy greens, broccoli, Brussels sprouts, and mushrooms.
- Prioritize Quality: When purchasing animal proteins, always look for "pasture-raised" and "grass-fed" labels. This can be more expensive, but it is central to the diet's philosophy.
- Invest in a Pressure Cooker: For those who wish to include beans or lentils in their diet, pressure cooking is a necessary step to significantly reduce lectin content.
- Explore Plant-Based Supplements: For a convenient protein boost, consider a high-quality, lectin-free supplement like Gundry's own ProPlant Complete Shake, which features a blend of hemp, spirulina, and flaxseed.
- Experiment with New Foods: Branch out and try less common but approved foods like Barù nuts or sorghum to diversify your protein intake.
The Controversy Surrounding the Lectin-Free Diet
It is important to acknowledge that the lectin-free diet is controversial and not universally accepted by the mainstream medical community. Critics argue that the benefits of many lectin-containing foods—rich in fiber, vitamins, and antioxidants—are unfairly dismissed. Additionally, many cooking methods are known to reduce or eliminate lectins effectively. The restrictive nature of the diet can make it expensive and challenging to follow long-term, and some medical experts believe that for most healthy individuals, avoiding these foods is unnecessary. Before making significant dietary changes, especially if you have pre-existing health conditions, it is always wise to consult with a healthcare provider.
Conclusion: Finding the Best Source of Protein According to Dr. Gundry
While there is no single "best" source, the ultimate answer to what is the best source of protein according to Dr. Gundry is a commitment to high-quality, low-lectin options. This means choosing pasture-raised and grass-fed animal proteins, wild-caught fish, and a selection of lectin-free plant sources like hemp, spirulina, and Barù nuts. By focusing on these principles and preparing food correctly, followers of The Plant Paradox aim to reduce inflammation, improve gut health, and support overall well-being.

Frequently Asked Questions
Q: Why does Dr. Gundry say to avoid many common protein sources? A: Dr. Gundry recommends avoiding many common protein sources, such as soy, peanuts, and most legumes, because he believes they contain high levels of lectins that can damage the gut lining and cause inflammation.
Q: Are all eggs forbidden on the Plant Paradox diet? A: No, but there is a specific requirement. Dr. Gundry recommends eating only pasture-raised eggs, which come from chickens fed a lectin-free diet, unlike conventionally raised chickens.
Q: What about protein powders? Can I still use them? A: Yes, but Dr. Gundry advises choosing lectin-free, plant-based protein powders without added sugars, such as his own Gundry MD ProPlant Complete Shake, which contains hemp and pea protein isolate.
Q: Does Dr. Gundry recommend a ketogenic diet for protein? A: Dr. Gundry has authored a book promoting a lectin-free ketogenic diet that includes his approved proteins alongside healthy fats and specific dairy products, though he does not advocate for heavy, unlimited meat consumption.
Q: Can I eat beans and legumes at all on this diet? A: Yes, but only after properly preparing them. Dr. Gundry specifically recommends using a pressure cooker to effectively destroy the lectins in beans and legumes.
