The term “goitrogenic” means something that causes “goiter,” or swelling of the thyroid gland. Broccoli 2. Beyond limiting goitrogenic foods, other strategies I recommend to improve thyroid function include the following: There is no vitamin A in any plant food on the planet. For each log unit increase thiocyanate, FT4 decreased by 0.07 ng/dL in adolescent boys (p=0.003), corresponding to a 9% decrease relative to median FT4, respectively. Statement of hypercholesterolemia was demoted. Oxalate salts increase the risk of kidney stones, especially in patients with gut dysbiosis. In contrast, biochanin A was found to be an alternate substrate for iodination. The hypothalamus senses low T4 and releases TSH-releasing hormone, which triggers the pituitary gland to produce TSH. ... Hypothyroidism is a state generated by an underactive thyroid gland which generally implies that all the metabolic processes of the individual are carried out more slowly; thus, symptoms like cold intolerance, constipation, fatigue, weight gain, dry skin, goiter, and even depression can also occur [1][2], ... Hypothyroidism is a state generated by an underactive thyroid gland which generally implies that all the metabolic processes of the individual are carried out more slowly; thus, symptoms like cold intolerance, constipation, fatigue, weight gain, dry skin, goiter, and even depression can also occur [1][2][3]. It’s important to get tyrosine without those goitrogenic properties tagging along. Or does the ingestion of goitrogens tax our thyroid despite taking the meds? In a given week, if a patient is enjoying a couple of sides of steamed broccoli, a few servings of sauerkraut, and several small salads containing spinach and kale, that shouldn’t be a problem. If something disrupts thyroid function, the health consequences can be widespread. This effect can often be offset by supplementing with iodine. The strongest foods in this group are soy, millet, flax, and cruciferous vegetables. However, there are observations that indicate the existence of factors other than iodine deficiency. Reduce or eliminate goitrogenic foods from your diet. These investigators are examining the effect of the soy beverage on surrogate intermediate endpoint biomarkers (SIEBs) in patients at risk for breast and colon cancer, defining potential SIEBs in patients at risk for prostate cancer, and determining whether the soy beverage reduces the incidence of cancer recurrence. John T. Dunn, M.D. The concentration of genistein in most soy food materials ranges from 1-2 mg/g. Conclusions Certain groups of patients need to take special considerations when it comes to goitrogenic foods: As stated earlier, goitrogens reduce the uptake of iodine in the thyroid. Iodine content of only 11.9% salt samples was below recommended level of 15 ppm, 25.2% was between 15 and 30 ppm and 62.9% was >30 ppm. Iodine intake is a complex subject which you’ll find covered all over the internet. I was thinking that salicylates in the greens I was eating were contributing to my debilitating chronic fatigue, but now that this goitrogen information has come to light, perhaps it’s the goitrogenic foods that are contributing to the problem. The labelled compounds were injected into mice and sections of the whole animals were studied by an autoradiographic technique. Read on to learn what foods are goitrogenic, how food can be prepared to limit them, and which patients should be extra concerned about goitrogens. But, the natural sources of iodine for human beings are foods, ... Dietary goitrogens are substances that can interfere directly on iodine metabolism in thyroid. Many chemicals from the environment and medications are also classified as goitrogenic: At relatively low concentrations, goitrogens decrease the uptake of iodine by the thyroid gland. (ABSTRACT TRUNCATED AT 250 WORDS). Radishes 7. The truth is, goitrogens can be a problem, especially for patients with thyroid problems. Foods that have been identified as goitrogenic include cruciferous vegetables such as bok choy, broccoli, brussels sprouts, cabbage, canola, cauliflower, Chinese cabbage, coy sum, collard greens, horseradish, kai-lan, kale, kohlrabi, mizuna, mustard greens, radishes, rapeseed, rapini, rutabagas, and turnips. But goitrogenic foods have been vilified and it’s time to set the record straight. Goitrogenic foods, often referred to as simply “goitrogens”, are substances, either food or otherwise, that slow the production of thyroid hormones by lowering iodine uptake. Cabbage 4. Nonetheless, concern about the risk of toxicity caused by synthetic TKIs restricted their development as chemoprevention agents. When not enough iodine is available, the thyroid cannot produce sufficient levels of thyroid hormones T4 and T3. The total goiter rate was 34.96% (Grade 1- 32.15%; Grade 2- 2.81%) showing that IDD is a severe public health problem. However, a naturally occurring TKI (the isoflavone genistein) in soy was discovered in 1987. The easiest way to shutup a bully: ignore it. Cyanoglucosides are metabolized to thiocyanates which are anions that compete with iodine in thyroid hormone synthesis. At higher dose, it competes with iodine during protein binding [46], This article has no abstract; the first 100 words appear below. On the basis of the superior adsorption performance of nano-MOF materials, free residual ClO- and SCN- in water was rapidly, sensitively and selectively detected with a detection limit of 0.133 nM and 0.204 nM, respectively. In Europe, it’s estimated that up to 44 percent of the population maybe be iodine-deficient (6). This can lead to an increase in the thyroid stimulating hormone (TSH) causing the thyroid to become enlarged (goiter). Similarly tyrosine iodination is inhibited by SCN- with large variations, depending on the peroxidase, in the concentration of this anion required for inhibition. The inhibitory effect depends, in contrast, on the binding of SCN- to the substrate site with lower affinities. Rutabagas 8. Cook or steam foods prior to consumption which can naturally help to reduce the concentration of goitrogens in the plant/compound (13). #biomeonboardawareness. Antithyroid compounds may enter into the water, air and food exposure pathways, becoming an important environmental goitrogenic factor in man and other animals. All rights reserved. Moreover, nano-ZIF-8 was successfully used for monitoring the concentration levels of ClO- and SCN- in the specimens of tap water and Yellow River water. Do you think that lowering or doing a goitrogen detox might help with the chronic fatigue and brain fog? Oxalates protect plants from being eaten by critters and are found in most plants, nuts, and seeds. Even though my thyroid numbers are now good (good T3), I still have thyroid symptoms, like the fog and fatigue, and hair loss, dry skin and more. It could be delivered either in a purified state as a pill (to high-risk, motivated patient groups), or in the form of soy foods or soy-containing foods. Although some nutrients leach out, cooking goitrogenic foods is generally beneficial. Despite iodized salt supplementation programs, iodine deficiency is on the rise. In this article, we look at which foods and nutrients to … Design, Setting, Participants, and Intervention: This was a cross-sectional analysis of data from the 2009-2012 National Health and Nutrition Examination Surveys (NHANES) evaluating the exposure to perchlorate, thiocyanate, and nitrate in 3,151 participants aged 12-80. MANY opt for this method of cooking year round, and grilling is in full swing this time of year! For frame of reference, ingesting 250 mg of oxalates is considered high, and one cup of raw spinach contains a whopping 656 mg (11). Does ingesting goitrogens exacerbate our hypothyroid symptoms (like fatigue and brain fog and hair loss) despite having consistently good lab work? Spinach, okra, sweet potato, elderberry, figs, leeks, buckwheat, celery, other leafy greens, and dandelions are some sources. The Rosaceae family of fruits, which includes almonds, apricots, cherries, peaches, pears, plums, raspberries, and strawberries, is also goitrogenic. Thiocyanate overload in Central Africa, especially if also in conjunction with selenium deficiency. Common environmental contaminants can disrupt normal thyroid function, which plays essential but varying roles at different ages. Crucifers are the biggest goitrogenic offenders, with certain varieties of kale, collard greens, and brussels sprouts at the top of the list. In book: Bioactive Foods in Promoting Health (pp.691-716). Before you stop recommending antioxidant-rich fruits and vegetables to your patients, keep reading. correction… This 4-week salicylate elimination diet, however, relies heavily upon goitrogens since there are no amines, salicylates or glutamines included in it. Have your patients start with lower-iodine-containing foods and work their way up to higher levels. Goitrogenic foods can potentially inhibit iodine metabolism. Goitrogens accomplish this by interfering with iodine uptake in the thyroid gland. Goitrogens are classified as thiocyanate, isothiocyanate, cyanogenic glycosides, glucosinolates, thiourea, thionamides, flavonoids, etc. The high content of omega-6 fatty acids in industrial seed oils drives inflammation. I was about to do a low-salicylate elimination diet in order to see if this chemical was an issue and contributing to the fatigue because very often salicylate intolerance accompanies histamine intolerance and share the same symptoms (like fatigue and fog). Most flavonoids tested were potent inhibitors of TPO, with IC50 values ranging from 0.6 to 41 microM. Foods that have been identified as goitrogenic include cruciferous vegetables such as bok choy, broccoli, brussels sprouts, cabbage, canola, cauliflower, Chinese cabbage, coy sum, collard greens, horseradish, kai-lan, kale, kohlrabi, mizuna, mustard greens, radishes, rapeseed, rapini, rutabagas, and turnips. Chronic use of genistein as a chemopreventive agent has an advantage over synthetic TKIs because it is naturally found in soy foods. If the thyroid gland has difficulty synthesizing thyroid hormone, it may enlarge to compensate for this inadequate hormone production. The median urinary iodine levels in the studied areas were in the ranges from 12.5-17.5 microg/dl indicating no biochemical iodine deficiency in the region. If we’re supposed to eat 4-6 fruits and veges a day, yet oxalates can cause kidney stones et al even when cooked, and goitrogens seem to be in everything and cause thyroid disease, What the hell are we supposed to eat???? Patients Who Are Susceptible to Goitrogenic Foods, Further Dietary Considerations for Thyroid Health, Other Strategies to Improve Thyroid Function, National Board for Health and Wellness Coaching (NBHWC), Amiodarone (medication for irregular heart beat), Bromides (from pesticides, plastic, brominated vegetable oils, medications), Lithium and benzodiazepines (depression and anxiety drugs). Oxalic acid binds minerals like calcium and potassium, making them insoluble and less bioavailable (12). Influence of goitrogenic foods intake on thyroid functions in healthy females of childbearing age with low habitual iodine intake - Volume 74 Issue OCE1 - M. Bouga, F. Cousins, M. E. Lean, E. Combet For years, goiter was, Access scientific knowledge from anywhere. Goitrin can interfere with the synthesis of … Have your patients aim their macros to at least 20 percent carbs and 10 percent protein. In conclusion, it was demonstrated that a constant iodine intake through the diet for this patient with grade II hypothyroidism was very effective, and therefore, this aspect should be also considered during hypothyroidism treatment. Cruciferous vegetables such as broccoli, cauliflower, and cabbage naturally release a compound called goitrin when they’re hydrolyzed, or broken down. Pharmacologists have realized that tyrosine kinase inhibitors (TKI) have potential as anti-cancer agents, both in prevention and therapy protocols. A total of 961 school children in the age group 6-12 yrs of both sexes were clinically examined for goiter from three study areas- one from rural block and two from urban areas. It’s a crazy conundrum because my symptoms overlap with several conditions, I do not know what condition is causing what issue. Cauliflower 5. Goitrogenic foods: Goitrogenic are foods that can affect thyroid function by inhibiting synthesis of thyroid hormones, resulting in enlargement of the gland (goiter).Goitrogenic foods include Brussel sprouts, kohlrabi, turnips, rutabaga, radishes, cabbage, kale, and cauliflower. On the other hand, if a patient is downing green smoothies every day, each with two or more cups of raw kale or spinach, then I would be worried about how that’s affecting thyroid function. One in eight women will develop a thyroid disorder in her lifetime. Iodine deficiency also affects the socioeconomic development of a community. If you suspect a patient has thyroid issues, make sure you run a full thyroid blood work panel, which should include the standard TSH and T4, but also T3, free T3, free T4, and thyroid antibodies. Boiling crucifers for 30 minutes destroys 90 percent of the goitrogens by stimulating the production of myrosinase, an enzyme that helps deactivate goitrogenic glucosinolates (3). It is clear that the greatest goitrogenic factor among the world’s population is iodine deficiency. Seventy-five percent of people with goiter live in less developed countries where iodine deficiency is prevalent. Perhaps I should rethink this…. IODINE is necessary for thyroid hormone production. The best food sources of iodine come from the sea: seaweeds, cod, shrimp, and tuna. Now it is clear that the most important effects of iodine deficiency are on the developing central nervous system, and they form a continuum from mild intellectual impairment to full-blown cretinism. Goiter is usually the most obvious sign of iodine deficiency; however, brain damage, mental retardation, reproductive failure, and childhood mortality are more serious consequences. In contrast to cooking, fermenting increases the goitrogen content of cabbage, but it simultaneously decreases the level of nitriles (5). The foods that are classified as goitrogens include many vegetables such as, 1. Should we eat no more than Chris’ recommended 1 cooked serving of goitrogenic food daily? The role of thiocyanate in this regard may not be ruled out. Minerals (calcium, iron, etc. SCN- inhibits iodide oxidation (I- leads to I2) whatever the enzyme, thyroid, lactoperoxidase or horseradish peroxidase. Bottom line: encourage your patients to steam or boil goitrogenic foods and not to consume them in excess. Steaming crucifers until fully cooked reduces goitrogens by two-thirds. It’s time these plant compounds stop shoving you in a locker. Because of this, it’s probably important to mention that those people who don’t have a thyroid condition shouldn’t have a problem eating these vegetables. The stimulatory effect of SCN- is therefore seen as resulting from the binding of this anion to a limited number of high-affinity sites present at the surface of both thyroid and lactoperoxidases. Also, fatigue and fog are hypothyroid symptoms as well. A structure-activity study of 13 commonly consumed flavonoids was conducted to evaluate inhibition of thyroid peroxidase (TPO), the enzyme that catalyzes thyroid hormone biosynthesis. 1810 E. Sahara Ave, Suite 402 Las Vegas, NV 89104 USA | 702.850.2599, All photos on this page are courtesy of or unless otherwise marked. The effect of a pseudohalide, SCN-, an anion with the same molecular size as iodide, was studied on two reactions: thyroglobulin iodination and thyroid hormone synthesis (coupling reaction) catalyzed by peroxidases. The thyroid and its hormones control metabolism throughout the body, affecting the brain, GI tract, cardiovascular system, lipid and cholesterol metabolism, hormone synthesis, gallbladder and liver function, and more. So many foods that we eat daily and consider healthy are goitrogenic. Not that its needed anyway. This 4-week salicylate elimination diet, however, relies heavily upon goitrogens since there are no amines, salicylates or amines included in it. Hetzel² has . The Strongest Goitrogens are Soy products & Millet: Observations reveal that a number of plant foods usually consumed by the people of several regions contain goitrogenic/antithyroidal substances that interfere with thyroid hormone synthesis, acting at different levels in the thyroid gland and causing goiter and associated iodine deficiency disorders. If someone is already iodine-deficient, then goitrogens are more likely to cause issues. Other flavonoids inhibited TPO by different mechanisms, such as myricetin and naringin, showed noncompetitive inhibition of tyrosine iodination with respect to iodine ion and linear mixed-type inhibition with respect to hydrogen peroxide. Flavonoids are widely distributed in plant-derived foods and possess a variety of biological activities including antithyroid effects in experimental animals and humans. This is why I follow the carnivore diet. One hundred twenty urine samples were analysed for iodine and thiocyanate respectively. The results obtained in this work were satisfactory, having achieved improved blood levels of thyroid-stimulating hormone (1.78 μIU/mL) and reduced total cholesterol levels (198 mg/dL). The small, butterfly-shaped thyroid gland has big responsibilities. There are three types of goitrogens: goitrins, thiocyanates, and flavonoids. Cutting out vegetables and plant foods was the best thing I’ve ever done for my health. Tag: goitrogenic foods Iodine Deficiency in Vegans. One hundred and five edible salt samples were also collected from the households to evaluate the iodine content. Certain diets can improve hypothyroidism, or an underactive thyroid, while others can make the symptoms worse. I dry extra kale, spinach and other greens in the sun or on low heat in a dehydrator for addition to smoothies in the winter. If it can’t keep up with demand, it grows bigger trying. Median urinary iodine level was 21.80 µg/dl, and mean (±SD) urinary thiocyanate was 0.89 ± 0.49 mg/dl. For more information, check out my articles about the thyroid’s connection with cardiovascular disease, the gut microbiome, blood sugar, and more. In vivo, suicide substrate inhibition, which could be reversed only by de novo protein synthesis, would be long-lasting. In a study of Boston mothers, 47 percent of breast milk samples did not have sufficient levels of iodine (10). Let’s take a look at some of them and discuss how you can keep them in your diet, even if you have hypothyroidism. @article{Chandra2004GoitrogenicCO, title={Goitrogenic content of Indian cyanogenic plant foods & their in vitro anti-thyroidal activity. The objective of this work was to explore the effect of a constant iodine intake through the diet in a postmenopausal woman with subclinical grade II hypothyroidism, who also had mild hypercholesterolemia and obesity. I am very sick and tired of being sick and tired. To read the full-text of this research, you can request a copy directly from the author. I recommend only three to five servings per week of cooked cruciferous vegetables and other highly goitrogenic foods for these patients. After reading this article, I am leaning towards goitrogens., Wondering your thoughts on how ROASTING crucifers affects goitrogens? Are the goitrogenic effects of sprouts and micro greens of the cruciferous vegetables higher, lower, or the same? Naturally-occurring and anthropogenic agents may act as goitrogens, as well as some drugs, which in the presence of dietary iodine deficiency may exaggerate the goitre and associated disorders. : Les composés goitrogènes naturels se trouvent dans certaines plantes crues, telles que le manioc, le chou et les pousses de bambou. regarded as the chief consequence of iodine deficiency, with cretinism a separate manifestation confined to a few unfortunate victims. Certain foods … Additionally, we’ll look at some ways in which this deficiency can be avoided through diet and supplementation. It’s time to fight back. I’m always dismayed when women are told they have to avoid a healthy food when there isn’t a very good reason (a food allergy, for instance) for it. Main Outcome Measure Unfortunately, 20 million Americans suffer from some form of thyroid disease, and 60 percent of those who have it may not even be aware. Goitrogens can inhibit the transfer of iodine into a mother’s breast milk. For example, the progoitrin (one of the harmful downstream products of glucosinolates) content per dry weight of Russian kale is approximately 150 times higher than that of Chinese cabbage (1). Request PDF | Goitrogen in Food | Goitrogens are naturally occurring substances that interfere with the function of the thyroid gland. People of Kolkata should be advised to eat commonly consumed goitrogenic foods after boiling and decanting the water. Turnips This list is by no means exhaustiv… I deal with thyroid disorders often in my practice, and they can be very complex conditions. You may be surprised by how many common foods contain goitrogenic compounds, but the good news is, in most cases you don’t have to cross them off your grocery list. In addition, a significant improvement in relation to weight and body volume was reached (body mass index fell from 30.13 to 28.5 kg/m2), an important fact since it has impacted the overall well-being of the patient. Mean urinary thiocyanate level was 0.839+/-0.33 mg/dl showing that the people consume sufficient foods containing thiocyanate precursors. High activities were also found in the submaxillary salivary gland, the thyroid gland, the walls of the large vessels and the blood. Kale 6. In addition to my previous lengthy comment and questions, I have more questions. If we are taking thyroid meds (I am taking NP natural desiccated) and our numbers are all good, including free T3 in the upper 20 percentile of the normal range, will goitrogenic foods still be a problem to those of us with hypothyroidism? Gluten. It is present in the plant, and in the seeds of most Brassicae, as progoitrin, an inactive compound. Inhibition by the more potent compounds, fisetin, kaempferol, naringenin, and quercetin, which contain a resorcinol moiety, was consistent with mechanism-based inactivation of TPO as previously observed for resorcinol and derivatives. Unfortunately, cooking doesn’t decrease the oxalate content much. I do know that I have not tried a low-sal or low-goitrogen diet so perhaps one or the other could help. Reducing your intake to 3-6 servings per week will probably be sufficient. The aim of this blog is to provide a brief outline of the possible dangers of an iodine deficiency (hypothydroidism). As far as we know, this is the first time that nano-MOFs has been used as a selective fluorescence probe for ClO-/SCN- detection and anti-counterfeiting. Baseline anthropometric nutritional, pharmacological, and habit data were obtained, then the woman was scheduled for 1 month a diet in which she was provided food naturally containing iodine, so that the recommended requirements (iodine 150 μg/day) were met. Some good Paleo-friendly sources include pumpkin seeds, beef, fish, eggs, bananas, avocados, poultry, and almonds. Blood serum free thyroxine (FT4) as both a continuous and categorical variable. Goitrins, thiocyanates, and nitriles are all goitrogenic chemicals derived from natural plant pesticides called glucosinolates. The foods that have been associated with disrupted thyroid hormone production in humans are broadly classified into two categories: cyanogenic plant foods, and flavonoids containing plant foods. You can request the full-text of this chapter directly from the authors on ResearchGate. The two compounds studied gave an almost identical autoradiographic distribution pattern. You’ll notice that some of these goitrogenic foods are considered to be healthy foods, such as broccoli, cauliflower, brussels sprouts, etc. Goitrogens cause difficulty for the thyroid in making its hormone. . This was attributed to the fact that the activity after injection of KC14N was present mainly as thiocyanate. Simultaneously, ensure proper selenium intake. Eggs and iodized salt are also options. In contrast SCN- stimulates the coupling reaction: (a) this affect is seen with the thyroid and lactoperoxidases but not with horseradish peroxidase; (b) the concentration of SCN- required for half-maximal stimulation of the coupling reaction is much lower (0.5-1 microM) than that required for the inhibition of iodide oxidation (60-80 microM); (c) ClO4(-), an anion with the same molecular size as SCN- and I-, has no effect on the coupling reaction; (d) this stimulatory effect of SCN- does not depend on a modification of the thyroglobulin molecule since it is not seen with horseradish peroxidase or in purely chemical coupling conditions. Corpus ID: 20522092. Iodine content in drinking water samples ranged from 1.8-2.6 microg/l showing that the studied region is environmentally iodine deficient. The coupling reaction was studied separately from the iodination reaction by using labelled thyroglobulin samples previously iodinated but containing little or no hormones. ), vitamin B12, vitamin A, and others are very well retained. Goitrogenic drugs. Objective The introduction of ClO- into nano-ZIF-8 solution induced a significant decrease in the characteristic fluorescence emission of Eu3+ at 613 nm. It is well-known that ClO- and SCN- can cause adverse effects on the environment and organisms; therefore, development of new strategies for detecting ClO- and SCN-, especially in water, are highly desirable. The increasingly popular keto diet may not be appropriate. Foods that have been identified as goitrogenic include spinach, cassava, peanuts, soybeans, strawberries, sweet potatoes, peaches, pears, kale and vegetables in the Brassica genus - which include broccoli, brussels sprouts, cabbage, canola, cauliflower, mustard greens, radishes, and rapeseed. If you follow these steps … Carbs and proteins both promote the release of insulin, which is required to convert T4 to T3. Thank you. Controlling for serum cotinine, BMI, total daily energy consumption, race/ethnicity, and poverty-to-income ratio, for each log unit increase in perchlorate, FT4 decreased by 0.03 ng/dL in both the general population (p=0.004) and in all women (p=0.005), and by 0.06 ng/dL in adolescent girls (p=0.029), corresponding to 4% and 8% decreases relative to median FT4, respectively. But not only cruciferous vegetables many other foods like Bamboo shoots, soy product, Cassava, Corn, lima beans, millets, linseeds, peanuts, pears, pine nuts, strawberries can contain varying amount of goitrogens. Some nuts and fruits are listed as well, but they generally have a milder effect. Here, we present a luminous Eu (III) complex-functionalized Fe3O4 nanoparticles encapsulated into the zeolitic imidazolate framework materials (nano-ZIF-8) and successfully employ this nano-MOF as a fluorescence probe for selective and sensitive detection of ClO- and SCN-. Gut bacteria are responsible for breaking down oxalates, but when the microbiota are compromised, oxalates can enter the blood, turn into crystals, and get stored in tissues like the kidney. Does this reduce the goitrogenic effect of these foods as steaming does? For patients with an autoimmune thyroid disorder, eggs, nightshades, and dairy products are common offenders. I must follow a low histamine diet (which is really hard to do!) The DFG Senate Commission on Food Safety organizes scientific meetings on current aspects of major importance to the safety of food, with the aim of reviewing and assessing the state of knowledge in a specific field. The ADAPT Health Coach Training Program is an Approved Health and Wellness Coach Training & Education Program by the National Board for Health and Wellness Coaching (NBHWC), Kresser Institute, a division of Chris Kresser LLC, a Nevada LLC
 Some foods, such as cassava, millet, sweet potato, certain beans, and members of the cabbage family, contain goitrogens. Does ingesting goitrogens weaken the effect of thyroid meds? Fortunately, cooking lowers the goitrogenic content of foods. 3. Results Taking a multivitamin supplement; Take vitamins, minerals (e.g. Other examples are bamboo shoots, millet, soy, spinach, sweet potato, tapioca, and yuca (cassava or manioc). Foods which have been demonstrated to have goitrogenic effects include soy, cassava (when crushed and not detoxified by soaking,) vegetables in the genus Brassica (such as broccoli and cabbage), [page needed] and other cruciferous vegetables.
