Thyroid and Gut Connection

The Gut Microbiome

Your gut microbiome is made up of around 100 trillion microorganisms. If your gut health is compromised, chronic illnesses can develop. Any number of things can disrupt the gut, including medication, chronic stress, refined carbohydrates, and industrial seed oils. 

Your gut bacteria can impact everything about your health, including how your brain responds to stress, how well your body can digest certain carbohydrates, the health of your immune system, how you store fat, and much, much more. If your gut microbiome is disrupted, it can cause dysbiosis—which leads to chronic illness.

Hypothyroidism diet: Foods for underactive thyroid

Correct diet for your thyroid can offer many benefits like reducing the risk of hypothyroidism, which can lead to numerous health complications. But what foods should you be consuming for your thyroid? Well, we are about to tell you, but first it’s important to understand just how important the thyroid truly is.

Our thyroid is often overlooked unless a doctor raises concerns about it. Although you may not think about it much, it plays a major role in producing hormones and regulating our metabolism. When this process is thrown off, it can cause hypothyroidism (underactive thyroid).

The good news is, hypothyroidism is manageable and one way to do so is through diet.

On the other hand, there are foods you should avoid as they can worsen symptoms and the condition itself.

Foods to avoid in a hypothyroidism diet

Many of the foods to avoid with hypothyroidism are common foods that should generally be avoided or limited as they do not contribute to good health. These items are:

Soy: Soy can interfere with hormones, especially in women.

Cruciferous vegetables: Generally food items like broccoli and cabbage are recommended for healthy eating, but not if you have hypothyroidism. This type of food can interfere with the production of thyroid hormones.

Gluten: Although commonly avoided by those with Celiac disease, gluten should also be avoided if you have hypothyroidism.

Fatty food: Fatty foods may interrupt the absorption of thyroid medications.

Sugary foods: With an already slower metabolism adding sugary foods will lead to greater weight gain.

Processed foods: Hypothyroidism can result in higher blood pressure, so the added salts from processed foods will only worsen this.

Too much fiber: Fiber is good to keep us regular, but not in the case of those with hypothyroidism.

Coffee: You may have to cut back on your morning coffee. Caffeine can limit the absorption of thyroid hormone replacement medications.

Alcohol: Alcohol can disrupt the production of thyroid hormones and reduce the body’s ability to utilize these hormones.

Hypothyroidism is something you can live with. Along with medications, a hypothyroidism diet can greatly improve your everyday life and assist your thyroid.
