News update_ can kale cause hypothyroidism_ – endocrineweb spoke with endocrinologist, angela m. leung, md

The vegetable du jour kale has been getting negative attention in the media recently. Yoga with adriene youtube 30 days Despite kale’s many nutritional benefits—including calcium, vitamin C, iron, fiber, and antioxidants—there is speculation that kale might be a contributor to hypothyroidism (an underactive thyroid). Jivamukti yoga schedule To uncover whether there is truth to this theory or the media is making much ado about nothing, EndocrineWeb spoke with Angela M. Yoga facial exercises for wrinkles Leung, MD, who is an endocrinologist and Clinical Assistant Professor of Medicine at UCLA David Geffen School of Medicine, Los Angeles, CA, and Chair of the Public Health Committee at the American Thyroid Association.


Kale is considered a goitrogenic food, meaning that it contains substances (goitrogens) that may contribute to an enlarged thyroid. Beginner yoga poses In fact, all cruciferous vegetables like kale are considered goitrogenic, including arugula, bok choy, broccoli, brussel sprouts, cabbage, cauliflower, collard greens, mustard greens, turnips, and watercress.

These vegetables “contain the substance thiocyanate, which in very high concentrations, can interfere with adequate iodine nutrition,” Dr. Yoga meditation quotes Leung said. Sunstone yoga The thyroid needs iodine to produce thyroid hormone, and “thus exposure to very high amounts of thiocyanate can potentially result in hypothyroidism (an underactive thyroid) and compensatory growth of the thyroid (goiter),” Dr. Yoga sutras of patanjali download Leung explained.

“For the general population, the many health benefits of eating kale and other cruciferous vegetables in usual amounts far outweigh any potential adverse risks to the thyroid,” Dr. Anusara yoga poses photos Leung said. Sivananda yoga basic level 01 practice “In usual amounts, kale consumption is healthy and should not be avoided, in contrast to some media reports which caution against all ingestion of cruciferous vegetables to promote thyroid health,” she said.

In people who already have a thyroid condition, “The risks of worsening a preexisting thyroid condition are likely minimal if goitrogenic foods are consumed in their usual amounts,” Dr. Dallas yoga center Leung said. Yoga west cinco ranch schedule “Patients should seek the advice of their physician for the proper management of their specific thyroid conditions,” she added.

“The thiocyanate content of kale has not been well-studied, and there are only sparse measurement data from limited reports,” Dr. Office yoga poses Leung said. Yoga teacher pay per class “As such, the exact amount of kale ingestion that may be associated with an adverse thyroid health risk is unknown. History of yoga timeline However, ingestion of kale—including raw kale—in usual amounts should be fine,” Dr. Sadhana yoga pokhara nepal Leung said.

In some reports in the press, juicing kale is the real culprit. Pregnancy yoga video for normal delivery “Although it has not been specifically studied, juicing kale concentrates the vegetable and thus potentially poses a greater risk toward iodine deficiency and hypothyroidism if ingested in large amounts on a very frequent basis,” Dr. Yoga funny picture Leung said. Tula yoga studio software “These risks may be exacerbated in individuals who are already iodine deficient, and these may include those with restricted diets, such as vegetarians and vegans,” she said.

The United States is considered generally iodine sufficient, as most people get enough iodine through their diet, from table salt (of which most, but not all, formulations have iodine added to it), and from iodine-containing multivitamins and supplements, Dr. Barefoot yoga Leung noted. Yoga in hindi app “However, adequate iodine nutrition is particularly important in women of child-bearing age and their children, given the importance of iodine and normal thyroid function on the developing brain in young infants. Yoga space se The daily recommended intake for iodine is 150 mcg (micrograms), and women who are contemplating pregnancy, pregnant, or lactating should supplement with a multivitamin containing 150 mcg daily. Sangha yoga shala It should be noted that iodine excess is also potentially dangerous, as it can similarly induce thyroid dysfunction, and ingestion of any supplement containing more than 500 mcg iodine per day should be avoided,” she said.

Thus, media reports of kale causing hypothyroidism does not seem likely in most cases. Yoga vancouver washington Eating greens in their usual amounts will not be a significant contributor toward thyroid disorders. Yoga moves utrecht As always, it is important to talk to your doctor regarding your individual risk for a thyroid disorder and what types of food are right for you.
