Can Corned Beef and Cabbage Cause Diarrhea

Early on in my journey with Hashimoto's, I realized that my own health significantly improved with the use of nutrition.

I had a hunch that I was not the only person that could see improvements in Hashimoto's with dietary changes, though I wasn't fully convinced that one particular diet was the answer for every single person. When I began working with clients with Hashimoto's, however, I noticed that the majority of people I did see improvement with, had implemented a dietary approach that was very similar to my own.

The question "What is the right diet to heal Hashimoto's?" is very complicated since we are all different, and although we may have the same condition, different interventions may be required for each of us to heal. As a healthcare professional and scientist, I consider myself to be diet-agnostic.

I try not to form too many attachments to any dogmas, be it diets, herbs, medications, or other treatment modalities. My goal is to simply try to find the most successful protocols, and to show my clients and readers what works!

That said, there are some common myths and questions I hear about food, the thyroid and Hashimoto's that I want to address, because many of these myths are based on facts that have been misunderstood.

While there may not be a "one-size-fits-all" diet that will work for everyone, there are some diet guidelines that are important to clarify for anyone looking to find the optimal diet for their individual situation.

Some questions that I'll cover as I debunk some common myths, include:

• Should I avoid broccoli if I have Hashimoto's?
• Is raw dairy better than pasteurized dairy?
• Are almonds a good substitute for grains?
• If I'm not celiac, can I eat gluten?
• Are diets such as low-carb or vegan diets bad for my thyroid?

Myth 1: Goitrogens should be avoided if you have Hashimoto's, so I can't eat broccoli.

Those poor cruciferous vegetables!

Delicious and healthy vegetables like cabbage, Brussels sprouts, broccoli, kale, and cauliflower have gotten a bad rap due to some old nomenclature and outdated patterns in thyroid disease.

"Goitrogen," a word coined in the 1950s, describes any substance that has the potential to contribute to goiter formation because of its ability to interfere with thyroid function. The tricky part is that not all goitrogens work in the same way.

The term "goitrogen" can be deceptive in that it can mean a variety of different things for different substances — from suppressing the release of thyroid hormone and changing the way thyroid hormone gets produced in the body, to suppressing the absorption of iodine.

For this reason, I like to look at research studies and clinical outcomes before I determine if a specific food is contraindicated for Hashimoto's.

Certain goitrogenic mechanisms make me cautious, such as the inhibition of the thyroid peroxidase enzyme or the inhibition of thyroid hormone release. I do recommend avoiding certain goitrogens that do this — these include soy and excess iodine.

I always recommend looking at scientific and clinical evidence that a substance may be harmful to the thyroid. For example, research studies have documented that canola (made from rapeseed), and nitrates found in processed foods, have direct toxic effects on the thyroid gland. However, the evidence of harm from other goitrogens such as cruciferous vegetables (broccoli, cabbage, turnip, etc.) is lacking.

Crucifers are considered goitrogens because they contain substances known as glucosinolates. When consumed in large quantities, glucosinolates can prevent the absorption of iodine into the thyroid gland.

This was a concern in the 1950s when the primary reason for hypothyroidism was due to iodine deficiency. However, since public efforts have been made to add iodine to the salt supplies of most industrialized countries, hypothyroidism induced by iodine deficiency became less of a concern. Today, Hashimoto's is the most common cause of hypothyroidism, accounting for some 95 percent of cases. (1, 2)

Iodine deficiency is not widespread in people with Hashimoto's, and most cruciferous vegetables do not have enough glucosinolates to induce iodine deficiency.

So unless you're already sensitive to cruciferous vegetables, eating them is perfectly healthy for most people with Hashimoto's, and should not impact thyroid function. (3, 4)

In my experience, most cruciferous vegetables are well-tolerated and offer health benefits for most people with Hashimoto's. They help the body detoxify, especially when cooked. Even in their raw state, I have not seen issues with cruciferous vegetables in most clients, except those with SIBO (small intestinal bacterial overgrowth), since crucifers are high in FODMAPs, which aggravate SIBO.

Cruciferous vegetables are also not recommended for those with the CBS genetic mutation or sulfur sensitivity, due to the high sulfur content of crucifers.

For people that do have concerns about iodine deficiency and crucifers, I recommend steaming, cooking, or fermenting the vegetables. This alone will be enough to break down the small amount of glucosinolates contained within the veggies. (5)

You can read more about the breakdown of the science behind the thyroid and goitrogens in this article.

Myth 2: I do not need to stop eating gluten, because tests indicate that I am not sensitive.

Gluten is a substance found in wheat, barley, and rye, and is a staple of the standard Western diet. We know that it's found in bread products, but it is also often hiding in other products like sauces, deli meats, candy, and even beauty products.

Celiac disease is a disease that causes an autoimmune attack on the gut when gluten is consumed.

People with Hashimoto's are more likely to have celiac disease than the general population, and eliminating gluten has helped some people dually diagnosed with celiac and Hashimoto's shed their Hashimoto's diagnosis (i.e. their antibodies went into remission, and their thyroid function returned to normal).

However, celiac disease is not the only problem related to gluten. My personal and clinical experience has shown that non-celiac gluten sensitivity (NCGS) is one of the biggest triggers in Hashimoto's. (You can read more about gluten-related issues and Hashimoto's, here.)

Lab testing can be very helpful to determine whether you are sensitive to gluten, but unfortunately, testing technology is not perfect. More often than not, false negatives can be seen for common reactive foods like gluten, dairy, and soy. The best test for figuring out if you are sensitive to gluten is doing an elimination diet, where you avoid gluten for two to three weeks, then try it again to see if you react to it.

Studies suggest that gluten can induce intestinal permeability in all individuals, regardless of whether or not they have celiac disease. And we know that intestinal permeability, or leaky gut, is almost (if not always) a factor with Hashimoto's. (6-8)

Therefore, it only makes sense that eliminating a common irritant like gluten will lead to improved gut health and overall wellness for many people with Hashimoto's.

When I surveyed 2232 people with Hashimoto's, around 90 percent of respondents reported feeling better on a gluten-free diet, even though only 10 percent were diagnosed with celiac disease.

Going gluten free can help alleviate many symptoms associated with Hashimoto's, such as fatigue, hair loss, bloating, constipation, diarrhea, pain, acid reflux, weight gain, and many others. It can also reduce the autoimmune attack on the thyroid gland. (9)

Going gluten free is one of the first things I recommend when you have a thyroid condition, be it Hashimoto's, hypothyroidism, or Graves' disease. If you have a thyroid condition, I suggest you give it a try for just two weeks to see if you feel better. (Remember, the best test goes by how you feel.) You can always go back to how you were eating if you don't feel any different.

Starting a gluten-free diet can be challenging, and many people have setbacks along the way — this is why I developed a quick start guide to help you ease into the transition.

Myth 3: Almonds are a "health food," so I should eat them every day.

In an effort to eat a healthier, nutrient-dense diet, many people turn to almonds as a substitute for eating grains. This is because almonds are very tasty and quite versatile, can be made into Paleo bread, can be used as a substitute for bread crumbs, and can be eaten as snacks.

Unfortunately, many people can be sensitive to almonds. In my experience with clients, after gluten, dairy and soy, almonds are one of the top reactive foods for people with Hashimoto's. I often see people develop new food sensitivities because they have not yet healed their gut issues.

I've found that people have a greater risk of becoming sensitive to almonds (and other foods) if they eat them daily. If you don't react to almonds now, I suggest rotating almonds with other foods, eating them only every three to four days.

Read this article about the best diet for Hashimoto's for more information.

Myth 4: The best source of selenium is Brazil nuts.

Selenium is a trace mineral that plays a critical role in thyroid function, and a deficiency in it has widely been recognized as an environmental trigger for Hashimoto's. Selenium acts as a catalyst to convert the inactive T4 to the biologically active T3, and helps protect thyroid cells from the damaging effects of hydrogen peroxide that is generated from the synthesis of thyroid hormones.

While selenium is a required nutrient for proper thyroid function, its effect is dose-responsive and it is considered to be a narrow therapeutic index supplement. In studies on the specific dose of selenium needed to reduce thyroid antibodies, doses below 200 mcg did not help reduce thyroid antibodies, and doses greater than 900 mcg per day were found to be toxic. (10)

Many people believe eating Brazil nuts will help boost their selenium levels. However, it's important to note that the selenium content in Brazil nuts can vary tenfold, depending on where the Brazil nuts were grown — which means that a Brazil nut can contain anywhere from 55 mcg to 550 mcg of selenium! (11)

Unless your Brazil nuts were tested for selenium content, you might be unknowingly overdosing or under-dosing yourself. Additionally, many people with Hashimoto's may be sensitive to nuts, so stocking up on Brazil nuts would be counterproductive.

For this reason, getting selenium from a supplement may be a better option for you. Selenium methionine in supplement form, at a daily dose of 200 mcg, has been clinically tested to show a 50 percent reduction in thyroid antibodies over the course of three months. Some clinicians may recommend a dose as high as 400 mcg per day. (12)

In another study, TSH, as well as TPO and TgAb antibodies, were reduced, and serum T4 increased, after six months of taking a myo-inositol and selenium supplement. (13)

I recommend taking a supplement like Rootcology Selenium and Myo-Inositol. This is a targeted blend designed to support optimal thyroid function, healthy hormone balance, and a healthy immune system.

Along with reducing thyroid antibodies and Hashimoto's symptoms, supplemental selenium may improve Graves' disease outcomes, and reduce the incidence of postpartum thyroiditis when taken during pregnancy (14, 15). I credit selenium supplementation and blood sugar balance with lowering my thyroid antibodies and helping me get rid of panic attacks.

My clients report the same results over and over again, along with fewer heart palpitations, more energy, and less hair loss. I've seen great results with Pure Encapsulations Selenium.

Myth 5: Raw dairy is fine for Hashimoto's, as it's only pasteurized dairy that's problematic.

Proponents of this myth have probably heard or read information about how the pasteurization process changes the protein structure of dairy proteins, making them more reactive. However, if you've already been sensitized to the dairy proteins casein or whey from drinking conventional milk, then consuming raw dairy, organic dairy, lactose-free milk, or goat's milk may still be a problem.

It is possible that if you drank raw dairy your whole life, you might not have developed a sensitivity, but in general, cow's milk is difficult to digest for many adults with Hashimoto's. Goat's milk is highly cross-reactive as well for those with cow milk sensitivity. Camel milk, however, may be well tolerated by people with Hashimoto's, as the proteins are different enough not to cross-react. (16)

The most common ways people experience a reaction to dairy include gut reactions (like bloating, diarrhea, and acid reflux), as well as lung reactions (coughing, asthma, sinusitis, postnasal drip, mucus) and skin flare-ups (eczema, rashes, acne).

The thing about dairy reactions, like all delayed food reactions, is that it's almost impossible to know if dairy is a trigger for you unless you eliminate all dairy for at least two or three weeks, and wait to see if some of the symptoms you are experiencing are alleviated. You can then slowly introduce dairy back into your diet and notice whether or not your symptoms return.

Dairy was a huge trigger for me, personally, and 60 percent of my clients have reported feeling better on a dairy-free diet! (Read more about my acid reflux and dairy story and why you should avoid dairy with Hashimoto's here.)

Myth 6: Low-carb eating is bad for people with thyroid issues.

It may come as a surprise, but carbohydrates are not a required element in our diet. Research suggests that around 45 percent of people with Hashimoto's may have carbohydrate metabolism issues. (17)

In my client work, I've seen plenty of proof that a low-carbohydrate diet can be extremely beneficial for Hashimoto's. In my survey of 2232 people with Hashimoto's, people who went on a low glycemic index diet reported improved mood (61 percent), energy (71 percent), and weight (53 percent).

Limiting carbohydrate intake (for instance, via a low glycemic index diet) while healing from Hashimoto's helps balance blood sugar, and will likely lead to feeling significantly more clear-headed, energetic, and less anxious. Furthermore, thyroid antibodies have actually been shown to trend downward with this kind of dietary plan.

In a 2016 study published in Drug Design, Development and Therapy, 108 people with Hashimoto's were randomized to follow a low-carbohydrate study diet for three weeks, and were then compared to a control group of 72 patients who were given a standard low-calorie diet without food restriction.

After just 21 days, all the patients in the study group on a low-carb diet showed a significant decrease in their levels of thyroid antibodies, which are known to indicate how aggressive the attack is on the thyroid gland. While other diet factors came into play, such as the exclusion of dairy, eggs, and goitrogens, the study lent weight to the benefits of low-carb style diets for people with Hashimoto's. (18)

I've seen with my clients that some people with Hashimoto's (though not all) may even benefit from an ultra-low carbohydrate diet such as a ketogenic diet, where high levels of fat are consumed, and carbohydrates are restricted to less than 20 grams per day.

While some people report feeling tired after starting a protein/fat-heavy diet, this is not always due to needing carbohydrates. If you're feeling tired on a diet of mostly fats and proteins, this could be due to low stomach acid, which leads to improper protein digestion. Improper protein digestion may make a person tired because digestion takes a lot of energy.

In my work, I've found that most of my clients with Hashimoto's have low or no stomach acid, which impairs their ability to digest protein foods. People who are low in stomach acid may find themselves naturally gravitating towards carbohydrates for energy, as carbohydrates do not require as much stomach acid as proteins do for proper digestion.

To improve digestion while increasing protein, I suggest starting your day with a green smoothie, increasing your veggie intake, and taking the protein digestive enzyme betaine with pepsin. Other options for increasing stomach acid and improving digestion include drinking hot lemon water or taking a teaspoon of apple cider vinegar in a glass of water with protein-containing meals.

Myth 7: Dietary changes can heal everything, so if I just eliminate more foods, I will be healed.

While some people have had great success through changing their diets, even going into complete remission from Hashimoto's, this is not always the case.

Don't get me wrong, eating a nutrient-dense diet that is free of reactive foods can do wonders, and is one of the first things I recommend. However, if you've been following a specific diet for three months and are not seeing results, you likely have a gut infection that is causing inflammation and preventing you from healing.

Gut infections lead to intestinal permeability, which is one of the main triggers of Hashimoto's. (19)

Eradicating most infections will require targeted treatments such as herbs, antibiotics, antifungals, or antiprotozoal agents. If infections are not treated, a person can become sensitive to more and more foods, further narrowing the list of foods that are tolerated.

If you suspect that you have a gut infection, I recommend the following tests:

• Small Intestinal Bacterial Overgrowth 2-Hr – This breath test from Genova Diagnostics screens for SIBO.
• GI Effects Comprehensive Profile – This panel from Genova Diagnostics uses DNA analysis to go beyond the standard parameters for identifying gastrointestinal disorders.
• GI Pathogen Screen with H. pylori Antigen – This panel screens for ova, parasites, bacteria, fungi, yeasts, and occult blood. It also checks for antigens to Helicobacter pylori, Entamoeba histolytica, Cryptosporidium parvum, and more.
• GI-MAP – This panel measures bacteria, opportunistic organisms, (ab)normal flora, parasites, fungi, and viruses. It also measures antibiotic resistance genes and virulence factors that contribute to pathogenicity.

You can read more about infections and testing in this article, and in my book, Hashimoto's Protocol .

Myth 8: I'm vegan/vegetarian, so my diet is already thyroid-friendly.

I'm a proponent of eating plenty of plant-based, nutrient-dense foods! But I also know from clinical experience that an exclusively vegan diet (or even a vegetarian one) is usually not the most helpful for those trying to heal their Hashimoto's.

Vegan diets can be lacking in beneficial amino acids (the building blocks of proteins), and a protein deficiency can worsen Hashimoto's symptoms. (20-23)

Multiple systems and organs in our bodies rely on amino acids for optimal functioning. For example, the thyroid relies on the amino acid tyrosine to produce thyroid hormones. While some plant-based foods do contain protein, they are often lacking in a diverse amino acid profile — meaning many of these foods are deficient in some essential (and non-essential) amino acids.

Some non-meat protein sources such as legumes (beans), dairy, grains, soy, nuts, and some seeds may also perpetuate intestinal permeability and prevent the healing of a leaky gut. This in turn can affect one's ability to absorb nutrients. (24-26)

Some other nutrients are hard to get from non-meat sources, contributing to nutrient deficiencies that may already present in (and exacerbate) Hashimoto's, including: (27-33)

• B12
• Magnesium
• Zinc
• Vitamin D
• Selenium
• Iron (Ferritin)
• Vitamin E
• Carnitine
• Essential fatty acids (DHA and EPA)

Those on vegetarian/vegan diets could try to get nutrients by eating plenty of the right types of foods, and taking supplements. But even if you manage to maintain a complicated diet like this, you would still likely be eating soy, grains, and (if not vegan), dairy. These three things are common triggers and/or food sensitivities for people with Hashimoto's — another reason why I usually recommend a diet with some animal products instead.

For more information, please read my article on vegan diets.

Myth 9: I already eat a nutrient-dense diet, so I don't need to supplement.

Along with incorporating foods that can heal the thyroid, such as high-quality protein and organic produce that contain the right vitamins and minerals, we must also ensure our bodies have the capacity to absorb these nutrients properly.

People with Hashimoto's often have suboptimal absorption and utilization of nutrients. The most common reasons behind this are:

• Low stomach acid: You may have been told that you have too much stomach acid, and that you need to take medication to reduce this. But what if I told you that it may actually be the opposite — that you may not be producing enough stomach acid? Research suggests that people with Hashimoto's and hypothyroidism often have hypochlorhydria (low stomach acid) or achlorhydria (lack of stomach acid). (34) When we have low stomach acid, we are at greater risk for many undesirable health consequences such as food sensitivities, gut infections (more on that below), and… you guessed it… nutrient deficiencies.

• Leaky gut: When functioning well, healthy human intestines are both a barrier and a filter. A layer of cells forms a mucus barrier, consisting of intercellular tight junctions similar to thread fibers that come together to form a piece of cloth. But what happens when those intestinal tight junctions become damaged and loose? Intestinal permeability, or leaky gut, is the result. There are numerous factors that can cause intestinal permeability, and discovering which trigger(s) are damaging your gut, is key to restoring its function. (35) Once you uncover your root cause, you can then work towards healing your gut, which will allow your body to start absorbing nutrients properly and heal your thyroid.

• Gut infections: Since gut infections can lead to intestinal permeability, removing the infections can be the missing link in gut repair. It can be tricky to identify which type of infection is the culprit, but a few common ones I see in my Hashimoto's clients include Blastocystis hominis , H. pylori , SIBO, and yeast overgrowth. Identifying and eradicating them will ensure the gut is able to "rest and digest" for optimal absorption and utilization of nutrients.

Thus, even if an individual is eating a nutrient-dense diet, if their digestive system is not able to use the nutrients effectively, they may still have low levels of nutrients. Check out my articles on using enzymes to support digestion, as well as how to address nutrient deficiencies, to learn a root cause approach to resolving this issue.
