10 Foods to Help Support Thyroid Health

You may not really know what it is or be able to point to where in the body it is, but the thyroid gland is a very important, albeit small, part of the body. It plays a crucial role in regulating many bodily functions, including metabolism, energy levels, and mood. Ensuring its proper functioning is crucial for your overall well-being. Thankfully, there are plenty of foods that specifically help to boost the health of your thyroid – and they’re easily available in your local supermarket.

What is the Thyroid?

The thyroid gland is a small, butterfly-shaped gland located at the base of the neck, just below the Adam’s apple. Despite its relatively small size, the thyroid plays a vital role in regulating many of our bodily functions. One of its primary functions is to produce hormones, primarily thyroxine (T4) and triiodothyronine (T3), which help control metabolism, temperature regulation, heart rate, and energy levels. These hormones influence almost every cell, tissue, and organ in the body, which impacts processes such as growth and development, digestion, muscle function, and mood. In essence, the thyroid gland serves as the body’s internal thermostat, regulating a delicate balance of hormones to maintain optimal bodily function. An imbalance in thyroid hormone production can lead to a range of health issues.

There are many factors that can influence the health and functioning of the thyroid gland. These can lead to thyroid disorders and imbalances. One significant factor is nutrient deficiencies, particularly iodine and selenium, which are essential for thyroid hormone production. Stress and chronic inflammation can also impact thyroid health by disrupting hormone production and signaling. Other items, such as environmental toxins including heavy metals and endocrine-disrupting chemicals, can interfere with thyroid function. Additionally, certain medications, autoimmune disorders like Hashimoto’s thyroiditis, genetic predisposition, hormonal imbalances, and aging can all contribute to thyroid problems. A diet high in processed foods, refined sugars, and unhealthy fats may also negatively affect thyroid function. Being aware of these factors and making the appropriate adjustments to lifestyle and habits will help support the thyroid gland.

One of the best ways to support your thyroid is by eating a healthy diet. A healthy diet in general, focused on fresh fruits and vegetables, lean proteins, healthy fats, and whole fiber carbohydrates, will do wonders for your thyroid gland. Avoiding as much as possible prepackaged, processed foods that are high in saturated fats, sugars, salt, and other chemical ingredients will also improve your thyroid health. There are, however, some specific foods that do a great job at supporting your thyroid. These are the best 10 foods for Thyroid health.

It supports thyroid health on a cellular level, containing beneficial MCT fats and amino acids that nourish the thyroid gland and encourage a healthy metabolism.
