What You'll Learn
Dr. Steven Gundry's background
Dr. Steven Gundry is an American physician, low-carbohydrate diet author, and former cardiothoracic surgeon. He was born on July 11, 1950, and graduated from Yale University with a Bachelor of Arts degree in 1972. He then went on to obtain an M.D. from the Medical College of Georgia and began his surgical residency at the University of Michigan.
During his residency, he participated in a research program run by the National Institutes of Health, sparking his interest in scientific research. Throughout his career, he has combined his research expertise with his knowledge of heart surgery, creating several innovations in the field. Notably, he helped pioneer the use of robots for minimally invasive heart surgery and holds patents for various medical devices, including the "Gundry Retrograde Cardioplegia Cannula," the "Skoosh Venous Cannula," and the "Gundry Lateral Tunnel."
In 2002, Dr. Gundry left his position at Loma Linda University School of Medicine, where he had served as Professor of Surgery and Pediatrics and Chairman and Head of Cardiothoracic Surgery. He then founded his own practice at the International Heart & Lung Institute, where he began treating patients with a new dietary philosophy. In 2008, he published his first book on nutrition, "Dr. Gundry's Diet Evolution."
Dr. Gundry has since published numerous other books, including the bestselling "Plant Paradox" series, which revolves around the potentially harmful effects of lectins, a type of plant protein found in many foods. He argues that lectins cause inflammation and contribute to various modern diseases. However, his claims have been criticized by scientists and dietitians as pseudoscientific and unsupported by mainstream nutritional science.
Despite the controversy, Dr. Gundry has gained success and media attention for his work, with celebrities like Kelly Clarkson and Usher crediting his diet for their weight loss. He continues to focus on research and writing, offering a unique perspective on human nutrition and health improvement.

The Plant Paradox diet
Lectins are present in many foods, including beans, legumes, nightshade vegetables (like eggplants, peppers, and tomatoes), dairy products, and grains such as wheat and rice. Gundry's diet suggests avoiding all foods containing lectins, arguing that eliminating these foods can lead to weight loss, improved health, and reduced brain fog. However, critics argue that there is little evidence to support these claims, and that lectins are typically harmless when eaten in moderation. Thorough cooking of lectin-rich foods can further reduce any potential negative effects.
The diet also provides suggestions for snacks and treats. For example, instead of cashews, peanuts, or pumpkin seeds, one can opt for pistachios, walnuts, or sesame seeds. Sweet potato fries cooked in lectin-free oil are another option to replace potato chips or French fries. Dark chocolate and coconut milk ice cream are recommended as occasional indulgences instead of candy bars and dairy-based ice cream.
While some people have reported success with the Plant Paradox diet, it is important to consult a healthcare professional before making any significant dietary changes, as lectin-rich foods can also be important sources of nutrients, proteins, and fibers in a balanced diet.

Lectin-free diet
Dr Steven Gundry is an American physician, low-carbohydrate diet author and former cardiothoracic surgeon. He is the author of The Plant Paradox, which promotes a controversial and pseudoscientific lectin-free diet.
The Plant Paradox diet, also known as the lectin-free diet, is based on the claim that lectins, a type of protein found in many common foods, are harmful anti-nutrients that cause inflammation and lead to many long-term health conditions like obesity, chronic inflammation, and autoimmune diseases. The diet plan cuts out foods that contain lectins, like wheat, beans, potatoes, nuts, and dairy.
According to Gundry, lectins are "edible enemies" designed to prevent predators, including humans, from devouring plants. He suggests that avoiding foods high in lectins or removing the "lectin parts" of a food can have drastic health benefits, helping to reduce weight, recover from chronic health conditions, and reduce brain fog.
Advocates of the lectin-free diet claim that it can reduce inflammation in certain medical conditions and help with weight loss. However, critics argue that there is little evidence to support these claims, and that lectins are typically harmless when eaten in moderation. Thorough cooking of foods high in lectins can also mitigate their potentially harmful effects.
Gundry's diet has been criticised by some experts, including biochemist T. Colin Campbell, who states that The Plant Paradox contains numerous unsupported claims. Robert H. Eckel, an endocrinologist and past president of the American Heart Association, argues that Gundry's diet advice contradicts standard dietary recommendations.
Despite the criticism, Gundry has published several books promoting his lectin-free diet, including The Plant Paradox Quick and Easy, which offers a 30-day plan with meal plans, food lists, and recipes to help people adopt a lectin-free lifestyle.

Criticism of the diet
Dr Steven Gundry's diet has received a significant amount of criticism from scientists, dietitians, and doctors. His book, 'The Plant Paradox', promotes a lectin-free diet, claiming that lectins—a type of plant protein—cause inflammation, resulting in various modern diseases. However, many critics argue that Gundry's claims are unsupported and contradict mainstream nutritional science and dietary recommendations from reputable health organisations.
T. Colin Campbell, a biochemist and advocate for plant-based diets, states that "The Plant Paradox" contains numerous unsupported claims and fails to make a convincing argument that lectins are hazardous. Campbell further refutes Gundry's claim about demonizing fat, clarifying that he never advocated for a no-fat diet and is not a physician. Robert H. Eckel, an endocrinologist and past president of the American Heart Association, agrees with the criticism, arguing that Gundry's diet advice contradicts established dietary recommendations from organisations like the American Cancer Society and the American Heart Association.
Food writer and chef Anthony Warner adds that Gundry's theories are not supported by mainstream nutritional science, and the evidence supporting high-lectin diets is overwhelming, rendering Gundry's arguments questionable. Warner's sentiment is echoed by Today's Dietitian, which concludes that recommending a lectin-free diet would be nonsensical for any dietetics professional.
In addition to concerns about the accuracy of Gundry's claims, critics have also questioned his research methods and referencing. "The Plant Paradox" has been criticised for incomplete data, lack of peer review, and sloppy referencing. One commentator noted that the book contains easily verifiable falsehoods and that Gundry's own research lacks control patients, making it impossible to draw any conclusions.
Furthermore, Gundry has been criticised for equating the sugar in fruit with that in processed foods. In "The Longevity Paradox", he advises avoiding various fruits due to their sugar content, despite evidence suggesting that inadequate fruit intake is a significant dietary factor in millions of deaths worldwide and protective against the development of type 2 diabetes.
Overall, while some followers of Gundry's diet have reported positive results, the diet has faced substantial criticism from experts who argue that his claims are unsupported, contradict mainstream advice, and may be based on questionable research methods.

Snack alternatives
Dr. Steven Gundry is an American physician, low-carbohydrate diet author, and former cardiothoracic surgeon. He is the proponent of the Plant Paradox diet, also known as the lectin-free diet. The diet is based on the claim that lectins, a type of protein found in many common foods, are harmful and cause inflammation, resulting in various modern diseases.
Dr. Gundry's diet includes several snack alternatives that are in line with his lectin-free approach. Here are some examples:
- Nuts and Seeds: Instead of cashews, peanuts, or pumpkin seeds, opt for pistachios, walnuts, or sesame seeds. Cashews, peanuts, and pumpkin seeds are high in lectins, while the alternatives are lower in lectin content.
- Chips and Fries: Swap potato chips and French fries for celery sticks or sweet potato fries. Potato chips and French fries are typically made from potatoes, which are high in lectins. Celery sticks and sweet potatoes are lectin-free alternatives. If frying, use a lectin-free oil.
- Chocolate and Ice Cream: Indulge in dark chocolate or coconut milk ice cream instead of candy bars and dairy-based ice cream. Dark chocolate contains less sugar and is often a healthier option. Coconut milk ice cream is free of dairy lectins.
- Dairy Products: Choose limited dairy products, such as ghee or goat/sheep-sourced dairy. Traditional dairy products like milk, cheese, and yogurt are high in lectins. Ghee is clarified butter with a lower amount of dairy proteins, while goat and sheep dairy may have lower lectin levels.
- Resistant Starches: Include green bananas, sweet potatoes, or yams in moderation. These foods provide a source of carbohydrates that are digested more slowly and may have lower lectin levels compared to other starchy options.
- Vegetables: Fill up on vegetables like asparagus, beets, broccoli, carrots, cauliflower, leafy greens, mushrooms, and spinach. These vegetables are generally low in lectins and provide a range of essential nutrients.
