Thyroid And Mediterranean Diet: Optimizing Your Hormone Levels

how to increase thyroid levels on mediterranean diet

The Mediterranean diet is a popular eating pattern that focuses on fruits, vegetables, whole grains, and healthy fats. It has been associated with numerous health benefits, including a reduced risk of cardiovascular disease, type 2 diabetes, and cancer. While there is no one-size-fits-all diet for thyroid health, the Mediterranean diet has been suggested as a protective choice for those with autoimmune thyroid disorders. This is because it can help reduce inflammation, which is often a contributing factor to thyroid issues. Additionally, the diet's emphasis on whole foods and nutrients like selenium and iodine may support thyroid function. However, it is important for those with thyroid conditions to monitor their iodine intake, as excessive iodine can also lead to thyroid problems. Overall, the Mediterranean diet may be a beneficial approach for those looking to improve their thyroid health and overall well-being.

Selenium-rich foods

Selenium is a mineral that supports thyroid hormone production and helps protect the thyroid from damage caused by oxidative stress. Selenium-rich foods can increase selenium levels in the body. The amount of selenium in different foods depends on the selenium content of the soil in which the food was grown.

  • Brazil nuts are high in selenium and can be added to a Mediterranean diet.
  • Fish, such as tuna, is a selenium-rich food that is also high in protein.
  • Lean meats, such as beef, pork, and chicken, contain selenium and can be included in the Mediterranean diet in moderation.
  • Eggs are a good source of selenium and can be cooked in various ways to suit individual preferences.
  • Dairy products, such as cow's milk and plain low-fat yogurt, contain selenium and can be added to a Mediterranean diet.
  • Whole grains, such as whole wheat bread and whole wheat pasta, can provide selenium and are commonly consumed in the Mediterranean diet.

It is important to note that while selenium is essential for thyroid health, excessive intake of certain nutrients can be harmful, especially for people with autoimmune hypothyroidism. It is always recommended to consult a healthcare professional to determine your target nutrient levels and develop a suitable dietary regimen.

Iodine-rich foods

Iodine is an essential mineral that must be obtained from one's diet as the body cannot produce it. Iodine is critical for the thyroid and plays an important role in the production of thyroid hormones. The thyroid gland needs iodine to function properly. The World Health Organization (WHO) recommends an ideal daily intake of 150 micrograms (mcg) for adults, with an increase to 250 mcg in pregnant and lactating women.

Seafood and Fish

Seafood and fish are some of the best sources of iodine. Seaweed, in particular, is considered the best source of iodine. A 10-gram serving of dried nori seaweed (commonly used in sushi) contains up to 232 mcg of iodine, exceeding the daily required minimum. Other good options include cod, tuna, and shrimp. A three-ounce serving of baked cod provides 158 mcg of iodine, meeting the daily minimum. Three ounces of tuna provide about 17 mcg, contributing to about 11% of the recommended daily intake.

Dairy Products

Dairy products are also major sources of iodine, especially in American diets. The iodine content in milk and dairy varies based on the iodine in cattle feed and the use of iodine disinfectants during milking. On average, one cup of milk can provide 59-112% of the recommended daily amount of iodine. Yogurt is another good source, with one cup providing approximately half of the daily recommended amount. Cottage cheese is also an excellent source, with one cup containing 65 mcg of iodine.

Eggs

Eggs are another animal source of iodine. A single hard-boiled egg provides about 26 mcg of iodine. The iodine content is higher in the yolk, and eggs are also packed with protein and other nutrients like vitamin D.

Iodized Salt

Most table salt has been iodized, making it a convenient way to add iodine to your meals. However, it's important not to rely solely on salt, and it should be paired with other iodine-rich foods.

Turkey Breast

Turkey breast is a lean protein and a solid source of iodine. It helps regulate hormones, keeps you full, fuels muscle repair, and is a heart-friendly option.

Prunes

Prunes, or dried plums, are an unexpected source of iodine. They support thyroid function by aiding in iodine absorption. They are also fiber-rich, antioxidant-rich, and easy to incorporate into your diet.

Plant oils

The Mediterranean diet is mostly plant-based and includes a high consumption of whole grains, fruits, and vegetables, with moderate alcohol intake during meals. It is considered to have a positive impact on health, reducing the risk of cardiovascular diseases, chronic kidney diseases, type 2 diabetes mellitus, and cancer.

Olive oil, a cornerstone of the Mediterranean diet, contains oleic acid, a health-supportive fatty acid. Extra virgin olive oil has been scientifically proven to reduce inflammation, which is beneficial for thyroid health. For individuals with Hashimoto's thyroiditis, an autoimmune condition, extra virgin olive oil helps protect thyroid cells from damage caused by the immune system's inflammatory response.

Additionally, plant oils have been associated with increased triiodothyronine levels in patients with hypothyroidism. Triiodothyronine, also known as T3, is a thyroid hormone that plays a crucial role in regulating metabolism and energy levels in the body.

It is important to note that while the Mediterranean diet is generally considered beneficial for overall health and thyroid function, individual responses may vary. It is always advisable to consult with a healthcare professional before making significant dietary changes, especially if you have a pre-existing thyroid condition.

Whole grains

The Mediterranean diet is mostly plant-based and includes a high consumption of whole grains, fruits, vegetables, legumes, and fresh produce with moderate consumption of alcohol during meals. It is considered to have an important role in preventing cardiovascular diseases, chronic kidney diseases, type 2 diabetes mellitus, and cancer.

When following the Mediterranean diet, some recommended whole grains to include are brown rice, rolled oats, quinoa, and brown rice pasta. These can be incorporated into meals in various ways, such as having quinoa salads, oatmeal for breakfast, or whole grain pasta dishes. Whole grains are also a good source of complex carbohydrates, which provide a sustained release of energy throughout the day.

It is important to note that the Mediterranean diet also emphasizes reducing refined carbohydrates and added sugars. This aspect is particularly beneficial for thyroid health, as high sugar consumption can negatively impact thyroid function and contribute to inflammation. Therefore, replacing refined carbohydrates and sugary foods with whole grains can be a healthy choice for those looking to improve their thyroid function and overall health.

In addition to whole grains, the Mediterranean diet also includes a variety of other thyroid-supportive foods, such as extra virgin olive oil, nuts, seeds, legumes, and lean proteins. By incorporating these foods and focusing on whole, nutrient-dense options, individuals can improve their thyroid health and overall well-being.

Dairy products

The Mediterranean diet includes moderate consumption of dairy products, such as cheese, full-fat yogurt, Greek yogurt, and kefir. These dairy products provide a good source of iodine, which is important for thyroid function. However, some people with hypothyroidism may benefit from avoiding dairy products if they are sensitive to them. In such cases, a registered dietitian can help identify which foods to limit or avoid and develop a balanced eating plan that does not unnecessarily cut out nutrient-rich foods.

It is also important to note that dairy products can be contaminated with endocrine disruptors, such as Bisphenol A (BPA), which can impair thyroid function. Therefore, it is recommended to choose dairy products that are farmed without the use of pesticides or other endocrine-disrupting chemicals. Buying local or organic dairy products can help ensure lower exposure to these contaminants.

Additionally, dairy products can interact with thyroid medication. It is generally recommended to take thyroid medication on an empty stomach to promote optimal absorption. This includes avoiding dairy products for a certain period before and after taking the medication to ensure effective absorption. Consulting with a healthcare professional can provide guidance on how to incorporate dairy products into the diet while optimizing thyroid medication effectiveness.

Overall, dairy products can be a valuable part of a Mediterranean diet aimed at supporting thyroid health. However, it is important to consume them in moderation, choose low-contaminant sources, and be mindful of potential interactions with thyroid medication.
