In 2001, I made some major discoveries that changed the course of my career – and my own life. I met a patient suffering from heart disease, and his case seemed “hopeless” by textbook standards. But, we made some changes in his diet, and this man made a complete turnaround.
You see, in working with him, I learned about key nutrients that are often deficient in the average American diet, as well as some common foods that are toxic to the human body.
Here’s the clincher, however. When I first met this patient, I was dangerously overweight myself – with high blood pressure, bad cholesterol, and digestive issues. Even though I exercised and ate a low-fat, vegetarian diet, the weight just wouldn’t budge. But, by implementing my new research, I was able to lose 70 pounds AND completely turn my health around.*
The basis of my approach to a heart-healthy diet involves steering clear of lectins – plant proteins that occur naturally in many common foods.

So, What are Lectins?
Lectin-Free Diet 101: Identifying Lectins and Their Effects
Lectins are a family of plant proteins found throughout the plant kingdom which act as a sort of defense mechanism for plants. They’re abundantly present in legumes, like beans and lentils, grains, such as wheat, and nightshade vegetables, like tomatoes and eggplants. Even nuts, seeds, and certain fruits and dairy products can contain these sticky proteins.
Lectins can be tricky for your body to handle. These compounds not only resist being broken down in the gut, but they can also bind to the cells lining your intestines, potentially leading to a condition termed “leaky gut” — where small openings occur in the gut walls. This allows partially digested food, toxins, and bacteria to get into the tissues beneath it, stimulating an immune response in the human body, simulating a threat, and thus leading to health issues.1
In simple terms, humans can’t digest lectins properly. During the digestive process, some types of lectins might even bind to the cell membranes on the wall of your small intestine, allowing lectins to communicate with your cells and triggering a response from your body.2
Your body may respond with issues like nausea, diarrhea, vomiting, upset stomach, bloating, gas, and weight gain.3-5
Some people are more sensitive to lectins than other people. However, if you’ve had digestive issues for some time, or if you suffer from an autoimmune condition, you could be one of the sensitive ones.6
The good news is that it’s easier than it seems to reduce or remove lectins from your diet. It just takes a little bit of planning.
The Principles of the Gundry Lectin-Free Diet
Key Foods to Avoid
Embarking on the Gundry lectin-free diet means eliminating or reducing some common foods. In a nutshell, it’s crucial to avoid:
- Beans + Legumes: Opt for alternatives, such as avocados and plenty of green leafy vegetables.
- Grains: Try using coconut, cassava, or sorghum flour instead.
- Certain Nuts + Seeds: Avoid cashews, peanuts, pumpkins, and sunflower seeds.
- Nightshade Vegetables: Stick to leafy greens and cruciferous veggies over nightshades like tomatoes, potatoes, and eggplant.
- Dairy: Stick with A2 milk, goat’s milk, or consider coconut milk.
- Grain-fed and farm-raised animal proteins: Stick to grass-fed and grass-finished meats.
Launching Your Lectin-Free Journey
Transitioning Smoothly: Tips for Lectin-Free Newcomers
Embarking on a lectin-free journey can be daunting, but with a few tips, you can transition smoothly.
Start by familiarizing yourself with lectin-free foods, and slowly introduce them into your diet while phasing out the high-lectin items. You can print out my Gut Health Shopping List to help guide you on your journey (and your shopping journey, too).
Prep your kitchen by stocking up on lectin-free staples — think of avocado, leafy greens, and olive oil to set the stage. Take it one meal at a time, and keep a food diary to track how your body responds to these changes. Above all, be patient; dietary shifts take time to adjust to, both mentally and physically.
You should also start dabbling with pressure cooking and fermenting, as these methods can greatly help to reduce lectin content in some foods.
How To Reduce Lectins In Your Favorite Foods
In basic terms, you want to avoid high-lectin foods. However, knowing how to prepare lectin-rich foods can help you reduce the lectin content in your favorite dishes.
For example:
- Soaking your legumes and grains may help reduce their lectin content. Soak them overnight, and rinse them very well before cooking.7
- Pressure-cooking beans, potatoes, or tomatoes may help to significantly reduce their lectin content. A pressure cooker won’t get rid of all the lectins, but it can make an impact.8
- Peeling and Deseeding high-lectin foods, like squash, cucumber, eggplant, and tomatoes, can also make a difference, as lectins are much higher in these areas. Peel the skin, and take out as many seeds as you can.9,10
- Fermenting vegetables, fruits, and even legumes allows good bacteria to get in and break down some of those plant defenses. Again, it won’t kill all lectins, but may help to significantly reduce them.11
Meal Planning That’s Not Boring
Now, let me be clear – eliminating high-lectin foods doesn’t mean that your diet is going to become boring. In fact, I think it gets even more flavorful!
Imagine kick-starting your day with a breakfast of scrambled omega-3 eggs and sautéed spinach. For lunch, a salad of romaine, wild-caught salmon, and an array of veggies dressed with olive oil. Dinner could be a delectable serving of grilled grass-fed steak with a side of roasted broccoli and Brussels sprouts. Snack on macadamia nuts, and if you crave something sweet, enjoy a small bowl of mixed berries or some dark chocolate. You can also visit my lectin-free recipe portal for a multitude of delicious recipes.
And, this way of eating does nothing to limit how much healthy fat you can consume. A lectin-free diet embraces plenty of healthy oils, such as extra-virgin olive oil or avocado oil. Remember, a lectin-free eating plan isn’t about calorie control, it’s about controlling those nasty lectins in your foods.
With a carefully curated shopping list, you’re setting the foundation for a successful and nourishing lectin-free lifestyle.
Integrating a Lectin-Free Approach Into Your Lifestyle
Lectin-Free Diet 101: Dining Out, Social Events, and Holidays
Navigating social dining while maintaining a lectin-free diet can be less stressful with preparation and communication.
When dining out, choose restaurants that offer customizable options, and don’t hesitate to ask questions about the menu. During social events or holidays, consider bringing a lectin-free dish to share, ensuring there’s something you can enjoy. Open communication with hosts about your dietary needs helps, as many are willing to accommodate. Remember, it’s about balance. Occasional deviations won’t derail your efforts, so enjoy the social aspect of food while sticking to your goals as closely as possible.
Recipe Modifications and Cooking Tips for Home Chefs
Transforming existing recipes into lectin-free delights can be a fun and creative process. Start by swapping out high-lectin ingredients with low-lectin alternatives.
For example, replace traditional flour with cassava or coconut flour in your dreamy baking endeavors. You can use lettuce wraps instead of bread for sandwiches and burgers or I have some delicious approved breads on my shopping list. You can also check out our lectin free food category for snacks and cooking ingredients – including gut-friendly tomato sauce!
With these adaptations, you’ll continue to enjoy cooking and eating a variety of tasty meals at home, all while staying true to your lectin-free lifestyle.
FAQ: Addressing Common Curiosities and Concerns
Is it Possible to Completely Avoid Lectins?
Completely avoiding lectins can be challenging, since they’re naturally present in many plant-based foods. Although a lectin-free diet minimizes exposure, it’s nearly impossible to eradicate them entirely from your diet. The focus should be on lectin reduction, opting for foods with lower lectin levels, or preparing foods in ways that help diminish their lectin content.
How Quickly Can I Expect to See Results from a Lectin-Free Diet?
Results from a lectin-free diet can vary widely based on individual health factors and adherence to the diet. Some may notice positive changes in digestion, energy, or irritation within a few days to weeks, while others might take longer to observe significant changes. It’s important to monitor how your body reacts, keep a food diary, and consult with a healthcare provider to ensure the changes you notice are indeed positive and sustainable.
Remember, quick fixes are rare in nutrition, and lasting health benefits usually result from long-term, consistent habits.
