6 Types of Foods That Can Negatively Affect Your Thyroid

The thyroid, a small butterfly-shaped gland located in front of your trachea in your neck, is a powerhouse of your metabolic system. It releases hormones that control how your body converts food into energy, and also influences heart rate, body temperature, brain development, mental activity, fertility, and more. When this vital gland doesn't function correctly, it can impact your entire body.

Common thyroid conditions include:

• Hypothyroidism (underactive thyroid)

• Hyperthyroidism (overactive thyroid)

• Goiter (enlarged thyroid)

• Thyroid cancer

While many thyroid issues are linked to genetics or autoimmune diseases and aren't always preventable, you can still take steps to manage your thyroid health, especially concerning iodine levels. Certain foods, in particular, can negatively affect how your thyroid works.

Foods to Be Mindful Of

Here are six types of foods that can negatively impact your thyroid function:

1. Soy and Soy-Based Products There's been extensive discussion about the negative effects of isoflavones, compounds found in soy products, on thyroid function. Isoflavones can hinder your body's ability to absorb iodine and thyroid medications.

2. Raw Cruciferous Vegetables Similar to soy, goitrogens – compounds found in cruciferous vegetables like broccoli and kale – can reduce iodine absorption. While these vegetables are generally healthy, those with thyroid concerns might want to consume them cooked or in moderation.

3. Gluten For individuals with autoimmune diseases, especially Hashimoto's thyroiditis (a form of autoimmune thyroiditis that causes hypothyroidism), avoiding gluten is often recommended. Gluten can trigger inflammation and immune system flare-ups, potentially worsening the condition.

4. Refined Sugar Refined sugar should ideally be avoided by everyone, but it's particularly detrimental for thyroid health. Its consumption leads to inflammation, increases insulin resistance, and can worsen common symptoms of hypothyroidism like weight gain, mood swings, and brain fog.

5. Processed and High-Sodium Foods Processed foods are notoriously high in sodium, which people with hypothyroidism should aim to limit. Hypothyroidism increases the risk for high blood pressure, and high sodium intake can further exacerbate this risk.

6. Coffee (Especially After Taking Medications) Many of us love a good cup of coffee. However, if you take medications for a thyroid condition, it's crucial to avoid drinking coffee for a few hours after taking your pills. Coffee can significantly reduce the absorption of thyroid medications, by up to 60%, diminishing their effectiveness and potentially slowing down your recovery process.

Foods That Support Thyroid Health

On the flip side, some foods are known to help maintain a healthy thyroid. These include fatty fish rich in Omega-3 like salmon and sardines, eggs, nuts and seeds, seaweed, and fruits rich in antioxidants such as berries, apples, and kiwi. Incorporating these into your diet can be beneficial.
