Too Many Antioxidants Are Bad For Our Health

How Kale & Other Vegetables Can Cause Thyroid Problems

Kale is loaded with antioxidants like vitamin C, vitamin E, and vitamin K, and other antioxidantal compounds like phytonutrients and polyphenols that are good for us.

Antioxidants and other relevant compounds in kale protect our cells and tissues from the oxidative stress of the free radicals and minimizes the risk of various cancers.

It also provides other benefits such as helps with detoxification, improves cardiovascular health, strengthens immunity, and improves cognitive functions.

However, in large quantities antioxidants may do more harm than good.

As per a study published by the Journal of the Cancer Institute, smokers who took large doses of beta carotene supplements were at higher risk of developing lung cancer in comparison to others who didnt.

Another study conducted by the office of dietary supplements states that in large doses vitamin E may increase the risk of hemorrhagic stroke.

In large quantities, antioxidants not only target the cancer cells but also the healthy cells around them.

This causes oxidative damage to healthy cells and tissues and increases the risk of various cancers.

Myth No : You Cant Eat Cruciferous Vegetables If You Have A Thyroid Disorder

Cruciferous vegetables, which include broccoli, cauliflower, Brussels sprouts and kale, have been thought to interfere with how your thyroid uses iodine. Iodine plays a role in hormone production in the thyroid gland. The truth is, you can and should eat these veggies.

Cruciferous vegetables are part of a healthy and balanced diet, and I encourage patients with thyroid disorders to continue eating them in moderation, says Dr. Bakar. You would have to consume an excessive and unrealistic amount of these vegetables for them to interfere with iodine and thus hormone production in the thyroid.

The 12 Worst Foods For Hypothyroidism

    If you’re constantly tired, weepy, and irritable, it might be a sign of thyroid problem. As many as 60 percent of the almost 20 million Americans who have a thyroid problem don’t even realize it, according to the American Thyroid Association.

    Your thyroid is the little butterfly-shaped gland at the front base of your neck. It regulates the release of hormones and regulates your metabolism. The most common issue is hypothyroidism, an underactive thyroid condition that leads to extreme fatigue, depression, forgetfulness, and weight gain. It can also increase your risk for heart disease, diabetes, and some cancers.

    While you can’t control all the risks that come with hypothyroidism, experts recommend following a nutritious diet and loading up on a variety of nutrients. “Be mindful of what you’re eating, get in colors and organics and no artificial colors or flavors. It’s about balance, right?” says , a nurse practitioner of functional medicine in Falmouth, Maine, with a program for balancing hormones and reducing fatigue. Read up on the worst foods for hypothyroidism, and then check out these 15 Subtle Thyroid Disease Symptoms You’re Ignoring.

    Fuzzy Science About Cruciferous Vegetables And Thyroid Health

    Kale and Your Gut

    The reason this whole debate came about in the first place was because of a few rodent studies showing hypothetical thyroid issues from eating very large amounts of cruciferous vegetables years ago.

    However, its very important to point out one basic fact: no human study has demonstrated a deficiency in thyroid function from consuming cruciferous vegetables.

    Theres only one study which seems to have been conducted looking into this issue. It found no effects on thyroid function after subjects were observed eating 150 grams of cooked Brussels sprouts daily for 4 weekswhich is far more than any normal human being would regularly eat!

    Only one case report relating cruciferous vegetables to thyroid harm suggests it would be almost impossible to consume enough cruciferous to harm the thyroid.

    In this case, an 88-year old woman developed hypothyroidism after eating 1-1.5 kg of raw bok choy every day for several months, which is obviously an excessive and unreasonable intake of raw cruciferous.

    The simple truth? You would have to consume an insane amount of raw cruciferous vegetables for them to have a negative effect on your thyroid function.

    Can Eating Too Much Kale Lead To Kidney Stones And Thyroid Problems

    Kale has been at the top of the healthy food list for some time. But it may actually cause kidney stones and thyroid problems.

    The generally accepted definition of “what’s good for you” is always temporary, vacillating constantly as dietary specialists highlight the importance or dangers of butter, carbs, alcohol and meat. But as far as vegetables were concerned, my personal motto has always been more is better. Eat everything in moderation, and when moderation has got you down, just add vegetables. I couldn’t have been more wrong.

    Moderation is important in all areas of diet and nutrition, even the parts that would appear to be very good for us.

    Last year, the dangers of consuming too much fruit were highlighted by scientists. This year, it appears that superfood darling and perhaps the world’s first trendy vegetable is the one being targeted. Apparently, kale might not be as good for us as we’d like to think… or at least, not in the quantities we’ve been consuming it in.

    According to the Linus Pauling Institute, kale and other crucifers contain glucosinulates, which can yield a compound known as goitrin, which has been linked to hyperthyroidism. To avoid this unfortunate side effect of your favorite dark green crucifer, try cooking kale, which lessens its goigrogenic properties, or occasionally replacing kale or consuming kale with seaweed, which adds more iodine into your diet and lessens the risks of thyroid problems linked to the production of goitrin.

    Worst Foods For Your Thyroid

    Processed Foods

    A huge proportion of the sodium we consume comes from processed foods and it is recommended that those with hypothyroidism should avoid excess sodium. Having an underactive thyroid increases your risk of developing high blood pressure and eating too much sodium can increase this risk further!

    Fried/ Fatty Foods

    Whilst it is generally accepted that fried foods arent the healthiest anyway, they can be particularly bad for anyone with low thyroid as fat can inhibit the bodys ability to produce enough of this particular hormone. This is true of all high fat foods, but fried foods are particularly bad as they pump a lot of fat into your system in one go. You should also try and avoid foods such as mayonnaise or margarine, as well as trying to eat as much lean meat as possible instead of meats with high fat content.

    Refined Sugar

    Someone with an underactive thyroid is more likely to have a slow metabolism and therefore is more at risk of gaining weight. Refined sugars arent good for you at the best of times, however if you are already at risk of gaining weight you will inevitably gain it much faster from these high sugar foods if you eat them a lot. Eating excess levels of refined sugars can lead to a number of other negative consequences, such as high cholesterol and fatigue as well as damaging your liver!

    How Cruciferous Vegetables Affect Your Thyroid

    Cruciferous vegetables belong to a group of related plants, and include the following produce:

    • Bok choy
    • Mustard greens
    • Turnips and turnip greens

    These vegetables are chemically unique in many ways, including their high level of sulfur-containing compounds called glucosinolates which gives them their distinctive smell.

    But glucosinolates and other chemicals in these veggies are considered goitrogens, which means they may interfere with the production of thyroid hormone mostly by disrupting your thyroids use of iodine. Your thyroid uses iodine for normal production of thyroid hormone, and if it cant access iodine properly or if there isnt enough iodine in your body, your thyroid hormone level will drop.

    For most people, goitrogens shouldnt be a concern and consuming cruciferous vegetables can lead to a number of health benefits, including a reduced risk of several types of cancer.

    Theyre not necessarily harmful if you have a normally functioning thyroid, says Luis O. Rustveld, PhD, RD, a dietitian and assistant professor at the Baylor College of Medicine in Houston.

    In fact, Rustveld says, many concerns that people have about cruciferous vegetables stem from animal studies showing that they can trigger hypothyroidism. One such study, in which researchers observed thyroid gland enlargement in rabbits eating cabbage, was published in 1928 and led to the discovery of dietary goitrogens.

    Should Spinach Be Avoided In People With Thyroid Conditions

    Is Kale A Poison To Your Thyroid Problems Or An Anti-Poison? Dr.Berg

    When it comes to avoiding specific foods, I truly believe that if you do enough research you can find a reason to not eat anything. If you follow a strict Paleo diet then you will be avoiding dairy and grains. If youre a vegan then you of course dont eat meat, fish, dairy, or eggs. In addition to this, if you have gut problems and are trying to avoid lectins, phytic acid, and other antinutrients, then besides avoiding grains you will want to cut out nuts, seeds, and legumes. Lets not forget sugar, and so we might as well cut out the fruit. And it probably would be a good idea to stop eating nightshade vegetables since they can be inflammatory. And if youre hypothyroid then you might want to cut out the goitrogenic foods too.

    The focus of this blog post is on spinach, which of course is a very healthy food. While it might not give you a boost in strength like it does with Popeye, eating spinach is high in nutrients such as vitamin A, magnesium, folate, and vitamin K. In fact, I frequently add spinach to my smoothies. Sometimes I will also eat spinach in a salad, along with other greens. And when I have the forbidden pizza, I enjoy adding spinach and garlic to it. Even my vegetable-hating children tolerate spinach.

    What Does Cruciferous Mean

    Cruciferous vegetables are indeed members of the brassica family. But where does the name come from? It originates from the Latin word Cruciferae, which means cross bearing. These veggies are called such names as they contain four metals that look like a cross.

    The cruciferous vegetables contain an enriched amount of vitamins, especially Vitamin D and K, and higher content of minerals like sodium, folate, etc. They even prevent cancer. Besides the several benefits of cruciferous vegetables, like offering an increased range of fibre and fewer calories, they come with the curse of triggering your thyroid.

    If you are an average eater of cruciferous veggies, they will shower you with only the benefits. However, with the regular addition of such veggies to your diet, they offer a terrible impact on your dysfunctional or underactive thyroid.

    You might love to take some green juice every morning, but if you see some enlarged thyroid action, you might want to drop it. It is even more harmful to eat these vegetables raw.

    Why so?

    They contain goitrogenic compounds like glucosinolates, which hamper the absorption of iodine by the thyroid gland. It ultimately leads to interference in thyroid hormone production. As a result, with lower iodine, the thyroid hormone level falls, leading to goitre or thyroid dysfunction.

    Before getting into the core there are a few foods you should avoid and you need to have a clear conception about that.

    Harvard Thyroid Doc Says Risk Is Theoretical Very Remote

    Could eating kale increase your risk of developing thyroid problems? A recent opinion column in the New York Times by Jennifer Berman suggested that eating kale and other cruciferous vegetables may have had a part in her developing hypothyroidism. But Dr. Jeffrey Garber, the Chief of Endocrinology at Harvard Vanguard Medical Associates disagrees, he says that your chances of developing hypothyroidism from eating kale are very low to miniscule.

    Your risk of developing hypothyroidism from eating kale is almost nonexistent

    Note: Jennifer Bermans doctor never told her to stop eating kale! Thats a conclusion she came to after reading things on the internet. Always talk to your doctor if youre planning to make big changes in your diet.

    Getting Iodine From Your Diet

    Being in the nutrition field I am not a fan of iodized salt because it contains 2.5% chemicals in the form of anticaking agents and is exposed to extremely high heat during processing. This process removes much of the minerals, which in turn can create a mineral deficiency and therefore more salt cravings as the body intelligently seeks to fill in its nutritional gaps.

    I prefer to use Himalayan or Celtic sea salt, which does not contain added iodine like traditional salt but it does contain all 84 essential trace minerals to support the nervous system.

    You can obtain adequate iodine from foods such as kelp, wild cod, wild shrimp and other shellfish, pasture-raised eggs, free-range turkey and organic raw milk.

    Can Raw Kale Cause Thyroid Problems

    Kale on its own does not increase the risk of thyroid problems. Its a combination of factors including potential iodine deficiency.

    Is Kale healthier raw or cooked?

    Cancer studies seem to show that raw kale is more beneficial than cooked, while cholesterol studies seem to show that steamed kale is more beneficial than raw, says Harris, who recommends a bit of both in your diet. But whatever you do, dont boil, saute or stir-fry the veggie too long or with too much added liquid.

    Coffee: Time Your First Cup Carefully In The Morning

    Per a study in the journalThyroid, caffeine has been found to block absorption of thyroid hormone replacement. “People who were taking their thyroid medication with their morning coffee had uncontrollable thyroid levels, and we couldn’t figure it out,” says Dr. Lee. “I now have to be very careful to tell people, ‘Only take your medication with water.'” You should wait at least 30 minutes after taking your medication before having a cup of joe.

    Excess Fiber From Beans Legumes And Vegetables

    Getting enough fiber is good for you, but too much can complicate your hypothyroidism treatment. The government’s Daily Guidelines for Americans currently recommends that adults up to age 50 should take in 25 to 38 grams of fiber a day. Amounts of dietary fiber from whole grains, vegetables, fruits, beans, and legumes that go above that level affect your digestive system and can interfere with absorption of thyroid hormone replacement drugs.

    If you’re on a high-fiber diet, ask your doctor if you need a higher dose of thyroid medication. Your maintenance dose may need to be increased if you aren’t absorbing enough medication.

    When deciding whether you should eat cruciferous vegetables, the first thing to consider is the advice of your doctor, says Rustveld.

    Its also important to keep tabs on how well your treatment for hypothyroidism is working, he says. If your thyroid levels are normal, you may have more room for choices in your diet.

    If your doctor leaves the decision to you, you should consider the potential benefits of these vegetables along with their risks.

    Dont underestimate the nutritional value of these vegetables, urges Rustveld. Cruciferous vegetables are a rich source of nutrients fiber, all kinds of vitamins, phytonutirents, antioxidants, he says.

    The bottom line: Check with your doctor, but if you want to consume them because you like them, and if you cook them well, then you should be OK.

    Being High In Powerful Antioxidants Like Sulforaphane And Vitamin C Fiber Carotenoids Vitamin E And K And Folate There Is Quite A Case For Consumption Of These Foods As A Big Contribution To Enjoying Greater Health

    They have long since been touted as supportive medicinal foods that help prevent cancer, support the liver, and contribute to improved immune and neurological health.

    However, cruciferous vegetables offer a unique dichotomy because they also contain compounds called glucosinolates which are connected to exacerbating iodine-deficiency related hypothyroidism that can lead to thyroid swelling called a goiter. Hence these foods are referred to as goitrogenic foods.

    They can do this by blocking the bodys ability to uptake iodine, which every cell of the body needs, but especially the thyroid, which contains the highest concentration of iodine in the human body. Those with pre-existing hypothyroidism may find that excessive consumption of raw cruciferous vegetables, could further suppress thyroid activity.

    However, you may have heard the saying the dose makes the poison and it takes a lot of brassica to be clinically significant.
