Dr. Steven Gundry is a well-known doctor, author, and cardiologist who founded Gundry MD, a website dedicated to improving health through diet, supplements, and education. He is the author of several books on healthy eating, including The Plant Paradox, Unlocking the Keto Code, and Gut Check, which discuss the potential dangers of lectins, a protein found in many plants and animals. The Plant Paradox Diet, also known as the Lectin-Free Diet, emphasizes whole, nutritious sources of protein and fat while banning nightshades, beans, legumes, grains, and most dairy. Tomatoes are considered nightshades and are banned on the Plant Paradox Diet, but Dr. Gundry states that they can be eaten if they are peeled and deseeded. This raises the question of whether tomato sauce, a common food product made from tomatoes, is allowed on the Gundry Diet.

Tomatoes are a nightshade vegetable, which are banned on the Plant Paradox Diet
Tomatoes are included in the banned food group because they are a source of lectins. Lectins are a protein found in many plant foods, and according to Dr. Gundry, they can cause inflammation, intestinal damage, and weight gain. While more scientific research is needed to back up some of Dr. Gundry's claims about the dangers of lectins, several studies have connected various lectin subgroups to altered gut microbiota, gut perforation, and overactive immune responses.
The Plant Paradox Diet emphasizes whole, nutritious sources of protein and fat while banning nightshades, beans, legumes, grains, and most dairy. It is fairly straightforward, as it simply involves avoiding lectin-containing foods. However, it is important to note that the research behind the diet has not been repeated, and there is little evidence to support the theory that lectins are as harmful as Dr. Gundry proposes.
While tomatoes are banned on the Plant Paradox Diet, Dr. Gundry does provide some guidance on how to make tomatoes safer to eat. He suggests that tomatoes can be consumed if they are peeled and deseeded. Additionally, cooking methods such as pressure cooking can help to remove lectins from foods.

Tomatoes can be eaten if peeled and deseeded, according to Dr. Gundry
Dr. Steven Gundry is a well-known doctor, author, and founder of Gundry MD, a website dedicated to improving health through diet, supplements, and education. He has authored several books on healthy eating, including The Plant Paradox, Unlocking the Keto Code, and Gut Check, which discuss the potential dangers of lectins, a protein found in many plants and animals.
The Plant Paradox Diet, also known as the lectin-free diet, is based on the claim that lectins are the "anti-nutrients" behind many chronic health conditions such as obesity, chronic inflammation, and autoimmune diseases. The diet plan cuts out foods that contain lectins, like wheat, beans, potatoes, nuts, and dairy. Dr. Gundry specifically suggests eliminating legumes and grains from the diet.
While tomatoes are included in the list of foods to avoid on the Plant Paradox Diet, Dr. Gundry mentions that some banned vegetables, including tomatoes, can be eaten if they are peeled and deseeded. This is because the skin and seeds of tomatoes contain lectins, which are considered harmful by Dr. Gundry.
It is important to note that while Dr. Gundry recommends a diet low in lectins, maintaining a completely lectin-free diet is challenging as they are abundant in our food supply. Additionally, there is limited scientific research to support some of Dr. Gundry's claims about the dangers of lectins. However, several studies have linked various lectin sub-groups to altered gut microbiota, gut perforation, and overactive immune responses.

Lectins are proteins found in many foods, including tomatoes
Lectins are a type of protein that can be found in many foods, including tomatoes. They are also referred to as "antinutrients" because they can reduce the body's ability to absorb nutrients. Lectins are found in all forms of life, including plants and animals, and are present in about 30% of the foods we eat.
Tomatoes are part of the nightshade family, which also includes potatoes, eggplants, and bell peppers. While tomatoes do contain lectins, they can be made safer to eat by cooking, sprouting, or fermenting them, which reduces their lectin content to negligible amounts. Cooking methods such as stewing, boiling, or cooking in sauce can break down lectins in tomatoes and other nightshade vegetables.
Some foods, like beans and grains, need to be cooked, fermented, or sprouted to reduce their lectin content. For example, raw kidney beans contain toxic levels of lectins, but boiling them for 5-10 minutes can reduce their lectin content to undetectable levels. Similarly, cooking, sprouting, or fermenting legumes, grains, and nightshade vegetables can make them safer to consume by reducing their lectin content.
While some lectins can be harmful if consumed in large quantities or poorly cooked, not all lectins are dangerous. Some studies have connected various lectin sub-groups to altered gut microbiota, gut perforation, and overactive immune responses. However, more scientific research is needed to back up these claims. Additionally, some lectins, like CLEC11A, promote bone growth, while others, like ricin, are powerful toxins.
Overall, while lectins are proteins found in many foods, including tomatoes, they can be rendered safe or even beneficial through proper cooking, sprouting, or fermenting methods.

Dr. Gundry recommends a diet low in lectins
Dr. Steven Gundry is a well-known doctor and author who founded Gundry MD, a website dedicated to improving health through diet, supplements, and education. He has authored several books on healthy eating, including The Plant Paradox, Unlocking the Keto Code, and Gut Check, which discuss the potential dangers of lectins. Lectins are a protein found in many plants and animals that can cause inflammation and poor gut health, leading to digestive problems, weight gain, and autoimmune diseases.
Some of the foods that Dr. Gundry recommends limiting or avoiding to reduce lectin intake include legumes, grains, nuts, seeds, dairy products, certain meats, and sugary snacks. However, it is important to note that eliminating these foods can make it challenging to achieve a balanced nutrition profile, potentially leading to adverse health effects.
To compensate for this, Dr. Gundry suggests incorporating specific superfoods into the diet, such as avocados, which are nutrient-rich and provide various health benefits. Other recommended foods include walnuts, macadamia nuts, pistachios, pine nuts, and extra dark chocolate containing at least 72% cacao for their antioxidant and anti-inflammatory properties. Additionally, Dr. Gundry promotes the consumption of shiitake and maitake mushrooms, sesame, basil seeds, and leafy greens, all of which are rich in various nutrients and offer potential health benefits.
While Dr. Gundry emphasizes the reduction of lectins in the diet, it is always advisable to consult a medical professional or dietician before making significant dietary changes, especially for those with specific health concerns or conditions.

Dr. Gundry provides a food pyramid outlining foods to consume and those to eat in moderation
Dr. Gundry's food pyramid is designed to help people achieve optimal health and improve their quality of life. The pyramid outlines the foods to consume and those that should be eaten in moderation.
The first pillar of the pyramid consists of good fats and approved oils, which Dr. Gundry considers the most important foods in our diet. These foods can be consumed in unlimited quantities. Good fats include avocados, which are rich in nutrients such as potassium, magnesium, fibre, vitamins A and C, and folate. Nuts, such as walnuts, macadamia nuts, pistachios, and pine nuts, are also recommended due to their antioxidant and anti-inflammatory properties.
The next portion of the pyramid focuses on healthy protein sources. Dr. Gundry suggests consuming wild-caught seafood, pastured poultry, and omega-3 eggs. He recommends limiting red meat consumption to 4 ounces per day, and choosing grass-fed or pasture-raised options, as they have higher levels of omega-3 and lower levels of omega-6 oils.
Dr. Gundry's pyramid also includes some beverages, such as red wine, which can be consumed in moderation (1-2 glasses, 1-2 times a week). He emphasizes that polyphenols in red wine may reduce the risk of cardiovascular diseases and promote heart health.
At the bottom of the food pyramid are foods that can be enjoyed anytime and in any quantity. These include shiitake and maitake mushrooms, which are excellent sources of prebiotics that stimulate beneficial bacterial growth in the gut. Sesame seeds, with their antioxidant and anti-inflammatory properties, are also recommended for preventing and reversing cardiovascular disease. Additionally, basil seeds are highlighted for their high protein, fibre, and mineral content, as well as their potential antimicrobial and anti-inflammatory effects.
Dr. Gundry's food pyramid challenges traditional dietary recommendations by eliminating most breads and grains, which often contain additives and preservatives. Instead, he emphasizes the importance of good fats, oils, and specific protein sources, while also incorporating certain superfoods and beverages in moderation.
