7 Foods To Avoid If You Have Thyroid Disease

Youve been probably advised not to include them raw in your diet when you suffer from hypothyroidism. However, they are packed with cancer-preventing phytonutrients. Eat them raw in moderation, cooked or juiced.

As hormones balance website says,

There is no evidence that cruciferous vegetables slow down or kill the thyroid. Unfortunately, there are many health bloggers who dont fact-check and have cut and re-pasted incorrect statements claiming that all leafy greens are foods to avoid with hypothyroidism, when thats not the case.

In fact, cruciferous vegetables are super nutritionally dense foods so they are good for women with thyroid issues who are often depleted in micronutrients.

Types Of Thyroid Cancer

There are 4 main types of thyroid cancer:

  • papillary carcinoma the most common type, accounting for about 8 in 10 cases it usually affects people under 40, particularly women
  • follicular carcinoma accounts for up to 1 in 10 cases and tends to affect middle-aged adults, particularly women
  • medullary thyroid carcinoma accounts for less than 1 in 10 cases unlike the other types, it can run in families
  • anaplastic thyroid carcinoma the rarest and most serious type, accounting for around 1 in 50 cases it usually affects people over the age of 60

Papillary and follicular carcinomas are sometimes known as differentiated thyroid cancers. They tend to be easier to treat than the other types.

Closer To An Anticancer Exercise Prescription Diet Is Less Clear

While there isnt yet enough of this robust kind of evidence to describe a specific antithyroid cancer diet, the role of exercise seems a bit clearer.11

“I would bet that exercise could extend the survival rate for people with thyroid cancer, says Neil M. Iyengar, MD, drawing on the findings from his recently published a review of the research on the potential for exercise to stop cancer.11 While the data are not definitive, Dr. Iyengar tells EndocrineWeb, we can draw from the evidence we already have, even if not the studies were not specifically performed with thyroid cancer in mind.

Dr. Iyengars bet is supported by the consensus of experts convened by the American College of Sports Medicine who endorse the strong evidence that exercise appears to reduce cancer risk by some 10-20% and improved survival for several different types of cancer.12

While thyroid cancer was not included on that list, it doesnt rule out possible benefits for this type of cancer, too. Rather, by gaining a better understanding for the mechanisms of thyroid cancer, we can understand whether and which changes in diet and types of exercise are most likely to have a positive effect.

Even so, given the available evidence, Dr. Iyengar believes we are moving towards a future where exercise can be specific and prescriptive in improving cancer incidence and outcomes.

How Many Calories Should You Eat with Hypothyroidism ...

“Processed foods tend to have a lot of sodium, and people with hypothyroidism should avoid sodium,” Frechman says. Having an underactive thyroid increases a person’s risk for high blood pressure, and too much sodium further increases this risk.

Read the “Nutrition Facts” label on the packaging of processed foods to find options lowest in sodium. People with an increased risk for high blood pressure should restrict their sodium intake to 1,500 milligrams a day, according to the American Heart Association.

    Fatty Foods Such As Butter Meat And All Things Fried

    Fats have been found to disrupt the body’s ability to absorb thyroid hormone replacement medicines, says Stephanie Lee, MD, PhD, associate chief of endocrinology, nutrition, and diabetes at Boston Medical Center and an associate professor at the Boston University School of Medicine in Massachusetts.

    Fats may also interfere with the thyroid’s ability to produce hormone as well. Some healthcare professionals recommend that you cut out all fried foods and reduce your intake of fats from sources such as butter, mayonnaise, margarine, and fatty cuts of meat.

    Hypothyroidism can cause the body’s metabolism to slow down, Frechman says. That means it’s easy to put on pounds if you aren’t careful. “You want to avoid foods with excess amounts of sugar because it’s a lot of calories with no nutrients,” she says. It’s best to reduce the amount of sugar you eat or try to eliminate it completely from your diet.

    Mayo Clinic Q And A: Hypothyroidism Spinach And Kale

    DEAR MAYO CLINIC: I have hypothyroidism and take medication for it. When researching online, I read that I should avoid kale and spinach. Is this true? I enjoy a kale or spinach smoothie almost daily and dont want to give that up. Are there other foods I should avoid because of hypothyroidism?

    ANSWER: Although you may find many claims about foods you should and shouldnt eat to ensure thyroid health, in general there are no specific foods you must avoid if you have hypothyroidism including kale and spinach. Eating a healthy, balanced diet and carefully taking your medication as prescribed by your health care provider will go a long way toward effectively managing hypothyroidism.

    Your thyroid is a small, butterfly-shaped gland at the base of the front of your neck. Hypothyroidism, sometimes called underactive thyroid, is a condition in which your thyroid gland doesnt produce enough of certain important hormones.

    The hormones that the thyroid gland makes triiodothyronine, or T3, and thyroxine, or T4 have a large impact on your health, affecting all aspects of your metabolism. They maintain the rate at which your body uses fats and carbohydrates, help control your body temperature, influence your heart rate, and help regulate the production of proteins.

    To help ensure that your body absorbs the medication properly, follow your health care providers directions on how to take it typically on an empty stomach.

    Gluten Found In Bread Pasta And Rice

    Those with hypothyroidism may want to consider minimizing their intake of gluten, a protein found in foods processed from wheat, barley, rye, and other grains, says Ruth Frechman, RDN, a dietitian in the Los Angeles area and a spokesperson for the Academy of Nutrition and Dietetics. And if you have been diagnosed with celiac disease, gluten can irritate the small intestine, and may hamper absorption of thyroid hormone replacement medication.

    An article published in May 2017 in the journal Endocrine Connections noted that hypothyroidism and celiac disease are often present together, and while no research has demonstrated that a gluten-free diet can treat thyroid conditions, you may still want to talk to a doctor about whether it would be worth eliminating gluten, or getting tested for celiac disease. A study published in July 2019 in Experimental and Clinical Endocrinology & Diabetes found that a gluten-free diet may have clinical benefits for women with thyroid disease.

    If you do choose to eat gluten, be sure to choose whole-grain varieties of bread, pasta, and rice, which are high in fiber and other nutrients and can help improve bowel irregularity, a common symptom of hypothyroidism. Also be sure to take your hypothyroidism medication several hours before or after eating high-fiber foods, to prevent them from interfering with the absorption of your synthetic thyroid hormone.

    Foods To Eat For Thyroid Problems:

Water helps your metabolism function better, and may help eliminate bloating and water retention, reduce your hunger, boost your digestion and elimination, and fight constipation. Some experts say that people have to drink one ounce of water per pound of scale weight.

    2. Berries: From strawberries to blueberries to raspberriesthe option is yours. Because they are bursting with antioxidants, which keep your own immune system strong berries pack a powerful impact. Eat a portion of berries daily.

    3. Legumes: A versatile and economical food, legumes are an excellent source if hypothyroidism leaves you feeling drained for continual energy, which may be useful. Legumes include complex carbs, antioxidants, protein, and lots of minerals and vitamins. In addition, they are full of fiber, which may be advantageous in the event that you suffer with constipation, a standard complication of hypothyroidism. In the event you are new to legumes, you can find lots of varieties to attempt, all of which may be used as the foundation for entrees, as side dishes, also to enrich salads, soups, and stews.

    Intake Of Vegetables Milk Products And Seafood May Reduce The Risk Of Thyroid Cancer

    In a hospital-based study in Sicily , the researchers from the University of Catania analyzed the dietary information from 106 thyroid cancer patients and 217 controls who were recruited at the University Hospital G. Rodolico of Catania and concluded that following a diet with limited starchy foods and products rich in salt, fat and sugar, and a higher consumption of cruciferous/non-cruciferous vegetables, milk and dairy products and seafood along with 1 to 2 L of daily water intake may help in reducing the risk of thyroid cancer.

    Another study done by the researchers from the Yale School of Public Health New Haven and Miami Cancer Institute in the US, and Peking Union Medical College Hospital-Beijing, Sichuan University and Capital Medical University, Beijing in China also found that those who followed dietary patterns rich in fruits and vegetables had a reduced risk of thyroid cancer, especially among women aged 50 years or older. They also found that the risk of thyroid cancer increased among men with a high intake of starchy foods and desserts.

    These studies suggest that taking vegetables, milk products and seafoods may help in thyroid cancer prevention. Also, we should avoid excess intake of starchy foods and desserts to reduce the risk of thyroid cancer.
