Dr. Steven Gundry is an American physician, low-carbohydrate diet author, and former cardiothoracic surgeon. He is the author of several books, including *The Plant Paradox*, which promotes a lectin-free diet. Lectins are a type of plant protein found in numerous foods, including beans. Dr. Gundry's diet suggests eliminating many foods because of their high lectin levels, such as whole grains, beans, nuts, fruits, and vegetables. However, critics argue that his theories are not supported by mainstream nutritional science and that a lectin-free diet is not only unnecessary but also potentially dangerous. While some beans are included in Dr. Gundry's No List, it is important to note that cooking and processing foods can reduce the number of naturally occurring lectins, and pressure-cooked beans are considered safe by some followers of his diet.

What You'll Learn
Beans are not recommended by Dr Gundry due to their lectin content
Dr. Steven Gundry is an American physician, low-carbohydrate diet author, and former cardiothoracic surgeon. He is the proponent of the controversial lectin-free diet, which suggests avoiding all foods containing lectins, a type of plant protein found in numerous foods. Lectins are claimed to cause inflammation, resulting in many modern diseases.
Beans are not recommended by Dr. Gundry due to their lectin content. While beans are generally considered a part of a well-balanced and healthy diet, Dr. Gundry suggests eliminating them because of their high lectin levels. He specifically mentions that raw beans, which contain lectins, could be harmful. However, cooking and processing beans can reduce the number of lectins, making them safer to consume.
In his book, "The Plant Paradox," Dr. Gundry advocates for avoiding lectins, which he believes are the source of many chronic illnesses. He also provides a "No List" of foods high in lectins, which includes all types of beans, such as green beans, chickpeas, and soy beans. Additionally, he mentions that even bean flours contain lectins, which should be avoided.
Some people following Dr. Gundry's diet have stated that pressure cooking beans can make them safe to eat. However, it is important to note that Dr. Gundry's lectin-free diet has been criticized by scientists and dietitians as pseudoscience. The claim that lectins are hazardous is not supported by mainstream nutritional science, and the diet may be unnecessary and potentially dangerous.
Overall, while beans are typically considered nutritious, Dr. Gundry's diet recommends avoiding them due to their lectin content, which he believes contributes to various health issues. It is essential to weigh the available information and consult a healthcare professional before making significant dietary changes.

Lectins are toxic proteins that can cause inflammation
Lectins are proteins that bind to carbohydrates. They are found in all plants, but raw legumes (beans, lentils, peas, soybeans, peanuts) and whole grains like wheat contain the highest amounts of lectins. Lectins are highly resistant to the body's digestive enzymes and can easily pass through the stomach unchanged. Lectins can also bind to cells lining the digestive tract, potentially causing an autoimmune response and playing a role in inflammatory conditions like rheumatoid arthritis and type 1 diabetes.
Lectins like ricin and phytohaemagglutinin can be toxic. Ricin, for example, is a poison created from castor beans. Its lectins specifically prevent cells from producing proteins necessary for their survival. Phytohaemagglutinin is a toxic lectin found in red kidney beans, and it can cause severe abdominal pain, vomiting, and diarrhea. However, properly cooked kidney beans are safe to eat, as cooking and processing foods tend to reduce the number of naturally occurring lectins.
Dr. Gundry recommends a diet low in lectins. He suggests eliminating foods with high lectin levels, such as beans, legumes, grains, nuts, fruits, and vegetables. However, maintaining a lectin-free diet is challenging, as lectins are abundant in our food supply. Cooking foods properly, especially beans, can drastically reduce the number of lectins in them. This may also include soaking, peeling, de-seeding, fermenting, boiling, or stewing foods to reduce lectins.
While lectins have been linked to negative health effects, it is important to note that many lectin-containing foods are associated with health benefits such as intentional weight loss and lower rates of cardiovascular disease and type 2 diabetes. These foods are rich sources of B vitamins, protein, fiber, minerals, and healthy fats. Thus, the health benefits of consuming these foods may outweigh the potential harm of lectins.

Cooking beans can reduce lectin content
Dr. Gundry's diet is centred around the elimination of lectins. Lectins are proteins found in all plants that bind to carbohydrates. They are a protective measure that helps the plant thrive and survive in nature. However, the same characteristics that protect plants can lead to digestive discomfort in humans.
Lectins are commonly found in whole grains, beans, nuts, fruits, and vegetables. Cooking and processing foods tend to reduce the number of naturally occurring lectins. For example, cooking dried kidney beans for a couple of minutes can destroy the lectins, but it takes about an hour of boiling them before they're edible. Soaking kidney beans in water for at least 5 hours, followed by boiling in fresh water for at least 10 minutes, is also recommended to remove lectins. Without presoaking, it takes 45 minutes in a pressure cooker to get rid of all the lectins. Canned beans are also safe to consume as the canning process involves cooking.
Dr. Gundry specifically suggests eliminating legumes and grains from one's diet. Beans are only safe to eat if they are pressure-cooked. However, it is important to note that maintaining a lectin-free diet is almost impossible, as lectins are too abundant in our food supply. A lectin-free diet may also not provide enough balanced nutrition to stay healthy. Instead, the goal should be to eliminate foods that contain high concentrations of lectins or work to remove them by proper preparation before consumption.
It is worth noting that some studies have shown that avoiding lectins altogether would mean avoiding almost all plant foods, which could be detrimental to health. For example, the longest-lived people in the world consume a mainly plant-based diet centred on beans, greens, nuts, and fruits. Additionally, lectin-containing foods like whole grains and beans are associated with lower rates of cardiovascular disease and type 2 diabetes. Lectins also have health benefits, such as acting as antioxidants and protecting human cells from damage caused by free radicals. They are also slow to digest and could prevent sharp rises in blood sugar.

Lectins are found in many healthy foods
Dr Gundry's diet is centred around the idea that lectins, which are found in many healthy foods, are the source of many chronic illnesses. Lectins are a type of protein that binds to carbohydrates and are found in all plants and animals, with some containing much higher levels than others.
Some foods that contain higher amounts of lectins include beans, peanuts, lentils, tomatoes, potatoes, eggplant, fruits, and wheat and other grains. Many of these foods are part of a well-balanced and healthy diet. For example, fruits and vegetables are recommended as part of a healthy, well-balanced diet due to their health benefits. Similarly, the Dietary Guidelines for Americans 2020-2025 recommend that about half of your grain intake should be whole grains, and that protein should include meat as well as beans, peas, lentils, nuts, seeds, and soy.
However, Dr Gundry suggests eliminating many of these foods because of their high lectin levels. He specifically suggests eliminating legumes and grains from your diet. Beans, for example, are only considered safe if they are pressure-cooked, as cooking and processing foods tend to reduce the number of naturally occurring lectins. Other methods of cooking and preparing food that can reduce lectin levels include boiling, baking, soaking, peeling, de-seeding, fermenting, stewing, and mixing into dough and baking.
It is important to note that there is no scientific evidence that eliminating dietary lectins will cure any medical disorders or conditions, including autoimmune diseases. In fact, a diet that avoids lectins is not one that most dietitians would typically recommend. Lectin-rich foods can be part of a healthy diet, and it is more effective to work with a dietitian to develop a structured and science-based diet that is customized to accommodate a person's individual sensitivities.

Dr Gundry's lectin-free diet has been criticised as unscientific
Dr Steven Gundry, a cardiologist, former professor of surgery and pediatrics, and world-renowned researcher and expert on lectins, has popularized the lectin-free diet, also known as the Plant Paradox diet. The diet is based on the claim that lectins, a protein in common foods, are the "anti-nutrients" behind many long-term (chronic) 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. Dr Gundry's lectin-free diet has, however, been criticized as unscientific. For instance, in his book, "The Plant Paradox", Dr Gundry references his \"published\" research, but a search on PubMed reveals that his last peer-reviewed full paper was on aortic surgery published in 2004. The abstract of his results is viewed in the scientific community as incomplete data not subject to the scrutiny of peer review.
Additionally, critics argue that there is no clinical evidence that the lectin-free diet is effective in treating any disease, and its claims have been criticized as pseudoscientific. Harriet Hall, writing for Science-Based Medicine, stated that Gundry's diet was not science-based and that following it risked dietary deficiencies. Preliminary studies have revealed health benefits from lectin consumption and minimal evidence of harm. Megan Rossi, a registered dietitian and spokeswoman for the British Dietetic Association, has commented that lectins are relatively easy to remove by cooking and preparing food in the right way, so they are not a concern for most people. She also noted that studies have shown that lectins possess "potential anti-carcinogenic effects".
Furthermore, in "The Plant Paradox", Dr Gundry equates the sugar in an apple with that in an energy drink or a Milky Way bar. However, the Global Burden of Disease Study identified inadequate fruit intake as the third most powerful factor in 11 million deaths annually worldwide due to dietary factors. The fact that fruit was found to be protective against the development of diabetes mellitus type 2 in a 7-year study of over 500,000 participants was not referenced.
Moreover, maintaining a lectin-free diet is all but impossible, as lectins are too abundant in our food supply, and one might not get enough balanced nutrition to stay healthy if they limit themselves to lectin-free foods alone. The goal, therefore, is to eliminate from one's diet the foods that contain the most concentrated amounts of lectins or work to remove them by proper preparation before consumption.
