A healthy diet is crucial for supporting thyroid function, whether you are managing hypothyroidism or hyperthyroidism. Your thyroid, a small yet potent gland in your neck, plays a significant role in controlling metabolism and various bodily functions. To foster good thyroid health, we need to be attentive to the foods we eat. Although there are many foods that have a positive impact on thyroid health, it is equally vital to acknowledge the ones that may impede it. Here, we will provide an exhaustive list of thyroid foods to avoid for the benefit of your well-being, enabling you to make informed choices.


Foods to avoid for hypothyroidism

Below are the types of foods to avoid with hypothyroidism.

  • Cruciferous vegetables: While vegetables such as broccoli and cauliflower boast a wealth of nutrients, they contain compounds that can disrupt thyroid function if consumed in excess. Cooking these vegetables can assist in reducing their impact.
  • Soy products: Soy contains goitrogens that can inhibit thyroid hormone production. Limiting soy-based foods like milk and edamame is advisable.
  • Gluten-rich food: Some individuals with hypothyroidism might benefit from reducing gluten intake, as there may be a potential link between gluten sensitivity and auto-immune thyroid conditions.
  • Fibre foods: Excessive fibre can impair the absorption of thyroid medication. While fibre is generally healthy, it’s advisable to consume it in moderation if you are taking thyroid medication.
  • Processed food: Highly processed food often contains additives and preservatives that may affect thyroid health. Opt for whole and unprocessed foods whenever possible.


Foods to avoid for hyperthyroidism

 Below are the types of foods to avoid with hyperthyroidism.

  • Iodine-rich foods: Excessive iodine intake exaggerates hyperthyroidism. If you have hyperthyroidism, limiting the intake of foods like iodised salt, fish, shellfish, seaweed, dairy products and iodine supplements is recommended.
  • Caffeine: The symptoms of hyperthyroidism can worsen with caffeine intake as it can stimulate the thyroid gland. Cutting back on caffeinated beverages like coffee, tea, and energy drinks can be beneficial.
  • Sugary foods: High sugar intake can disrupt hormone balance and contribute to energy fluctuations. Decreasing the intake of sugary foods and beverages can help maintain stable blood sugar levels.
  • Fatty and fried foods: Hyperthyroidism can lead to digestive issues, and consuming high-fat and fried foods might exacerbate these problems. Choose lean sources of protein and healthy fats.
  • Red dye and processed meats: Some processed meats and food products contain red dye, which might impact hyperthyroidism symptoms. It’s best to limit or avoid these items.
  • Egg yolks and blackstrap molasses: Both egg yolk and blackstrap molasses contain elevated levels of iodine, which can pose problems for individuals with hyperthyroidism.
