Gut Health and Hormones: Your Gut & Thyroid Function

The Gut-Thyroid Connection

When we think about thyroid health, we often focus on hormone levels and metabolism. However, your gut health plays a significant role in how well your thyroid functions. The gut is sometimes called the "second brain" because of how closely it influences various aspects of your body, including your immune system, nutrient absorption, and, importantly, hormone regulation.

Research shows that a healthy gut microbiome can support balanced hormone production, including the thyroid hormones that regulate metabolism, energy, and mood.

At Apex Health DPC, we emphasize a holistic approach to health, looking beyond symptoms to treat the root causes of hormone imbalances, starting with gut health.

In this article, we’ll explore how your gut affects thyroid function, what foods you should eat to support gut health, and how to improve overall hormonal balance naturally.

How Gut Health Impacts Thyroid Function

Your gut is home to trillions of bacteria that play a crucial role in digestion, immunity, and hormone regulation. A healthy gut microbiome can positively influence the production and conversion of thyroid hormones, while poor gut health may lead to hormonal imbalances that affect the thyroid.

What is the Thyroid?

The thyroid is a small, butterfly-shaped gland located at the base of your neck. Despite its size, it plays a major role in regulating your metabolism, energy levels, and mood by producing essential hormones like thyroxine (T4) and triiodothyronine (T3).

These hormones control how your body uses energy and influence nearly every organ system. When the thyroid is not functioning properly, it can lead to issues such as fatigue, weight changes, and even mood disorders. This is why maintaining good thyroid health, starting with your gut, is so critical for overall well-being.

1. Gut Health and Hormonal Regulation

The gut microbiome helps regulate key hormones in the body, including thyroid hormones. Specific gut bacteria produce short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate, which influence inflammation and immune function. When your gut is healthy, these SCFAs can help reduce inflammation, allowing your thyroid to function optimally.

However, if your gut is imbalanced—often referred to as dysbiosis—it can lead to increased intestinal permeability, or "leaky gut." This condition triggers immune responses that can interfere with the thyroid, potentially leading to conditions like hypothyroidism or Hashimoto’s thyroiditis. Research has also shown that gut bacteria play a role in converting inactive thyroid hormone (T4) into its active form (T3), which your body needs to regulate metabolism and energy levels.

2. Nutrient Absorption and Thyroid Function

Your gut health also affects how well you absorb the nutrients essential for thyroid function, such as iodine, selenium, and zinc. Poor gut health can limit your ability to absorb these critical nutrients, which are necessary for producing and regulating thyroid hormones.

• Iodine helps in the production of thyroid hormones.
• Selenium supports the conversion of T4 to T3, the active form of the hormone.
• Zinc is essential for thyroid hormone synthesis.

Maintaining a healthy gut ensures you absorb these nutrients efficiently, supporting optimal thyroid function and overall hormonal balance.

How to Balance Hormones and Gut Health Naturally

Improving gut health doesn’t have to be complicated. By making strategic changes to your diet and lifestyle, you can support a balanced gut microbiome and, in turn, boost thyroid function. If you're wondering "What foods should I eat for better gut health?", here are some natural ways to improve your gut health and promote hormonal balance:

1. Eat a Fiber-Rich Diet

Fiber is essential for promoting healthy digestion and feeding the beneficial bacteria in your gut. A fiber-rich diet helps regulate bowel movements and reduces inflammation, both of which are important for thyroid health.

Foods to Include:

• Whole grains (like oats, quinoa, and brown rice)
• Leafy greens (spinach, kale)
• Root vegetables (sweet potatoes, carrots)
• Legumes (beans, lentils, chickpeas)

Recipe: Fiber-Rich Grain Bowl

Ingredients:

• 1 cup cooked quinoa or brown rice
• 1/2 cup roasted sweet potatoes
• 1/4 cup black beans
• 1/4 avocado, sliced
• 1 tablespoon pumpkin seeds (rich in zinc)
• 1 handful of spinach or kale (lightly sautéed)
• Drizzle of olive oil and lemon juice

Instructions:

1. Combine the cooked quinoa or rice with roasted sweet potatoes and black beans in a bowl.
2. Top with avocado slices, pumpkin seeds, and sautéed spinach.
3. Drizzle with olive oil and lemon juice for a nutrient-dense, fiber-packed meal that supports gut and thyroid health.

2. Incorporate Probiotic-Rich Foods

Probiotics are beneficial bacteria that support gut health. Incorporating probiotic-rich foods into your diet can help restore balance to your microbiome, which, in turn, supports thyroid function and overall hormone regulation.

Probiotic-Rich Foods to Include:

• Yogurt with live cultures
• Kefir
• Sauerkraut
• Kimchi
• Kombucha

3. Reduce Inflammatory Foods

Inflammation can disrupt gut health and contribute to thyroid dysfunction. Reducing your intake of processed foods, added sugars, and unhealthy fats can help lower inflammation and protect both your gut and thyroid.

Foods to Avoid:

• Processed snacks and sugary treats
• Fried and fast food
• Excessive alcohol

4. Get Enough Prebiotics

Prebiotics are types of fiber that feed the beneficial bacteria in your gut. Including prebiotic-rich foods in your diet can help your probiotics thrive, further promoting a healthy gut environment.

Prebiotic-Rich Foods:

• Garlic
• Onions
• Asparagus
• Bananas
• Leeks

5. Add Bone Broth to Your Diet

Bone broth is rich in collagen and glutamine, which help heal and seal the gut lining. A healthy gut lining is essential for preventing inflammation and allowing proper nutrient absorption—both key factors in supporting thyroid function.

Benefits of Bone Broth:

• Promotes gut healing by reducing intestinal permeability.
• Supports the production of stomach acid, which aids digestion and nutrient absorption.
• Provides amino acids like glycine and glutamine, which play a role in thyroid health.

Recipe: Simple Homemade Bone Broth

Ingredients:

• 2 pounds of bones (beef, chicken, or turkey)
• 1 onion, quartered
• 2 carrots, chopped
• 2 celery stalks, chopped
• 2 tablespoons apple cider vinegar
• 10 cups of water
• Salt and pepper to taste
• Fresh herbs (optional: thyme, parsley, rosemary)

Instructions:

1. Place the bones, vegetables, and apple cider vinegar in a large pot.
2. Cover with water and bring to a boil.
3. Reduce heat, cover, and let simmer for at least 12 hours (longer for deeper flavor).
4. Strain the broth, discard the solids, and season with salt, pepper, and herbs.
5. Use it as a base for soups and stews with veggies, noodles, rice, or anything else you can think of.
6. Store in the fridge for up to 5 days or freeze for later use.
