Hypothyroidism

Hypothyroidism is an autoimmune condition that typically develops over time, often in individuals who consume a diet high in refined foods and certain animal products, such as dairy. Refined foods can damage the gut lining, allowing undigested proteins—including animal proteins like those found in dairy—to pass into the bloodstream. If these animal proteins contain thyroid beta cells (from the animal source), the immune system may identify them as foreign and produce antibodies to attack them. Unfortunately, these antibodies can also target the body’s own thyroid cells, leading to autoimmune damage. Over time—typically by the age of 40 to 50—this can result in weakened thyroid function.

The thyroid is a butterfly-shaped gland located below the larynx (voice box). One of its key enzymes is thyroid peroxidase (TPO), which plays a crucial role in thyroid hormone production. TPO oxidizes iodide ions to form iodine atoms, which are then attached to tyrosine residues on thyroglobulin to produce the thyroid hormones: thyroxine (T4) and triiodothyronine (T3).

T3 and T4 are tyrosine-based hormones that regulate metabolism, affecting how the body uses and stores energy. These hormones contain iodine, and a deficiency in iodine can reduce their production. T4 is the primary hormone released into the bloodstream and has a longer half-life than T3. In humans, the T4 to T3 ratio is approximately 14:1. T4 is converted into the more active T3 within cells by enzymes known as deiodinases, which require selenium—making dietary selenium essential for proper thyroid function.

Thyroid activity is regulated by the pituitary gland, which produces thyroid-stimulating hormone (TSH). TSH prompts the thyroid to produce T3 and T4. When the thyroid becomes underactive or sluggish, the body compensates by producing more TSH. This is why elevated TSH levels are a key indicator of hypothyroidism.

Hypothyroidism symptoms 

Most people with hypothyroidism experience no obvious symptoms, while others may feel tired. It is often difficult to determine whether fatigue is caused by hypothyroidism, poor nutrition, or emotional issues. Other common symptoms attributed to hypothyroidism include:

• Constipation
• Weight Gain
• Mild swelling eyes
• Feeling cold easily
• Decreased sweating
• Dry skin
• Eyebrow disappearance
• Brittle nails
• Shortness of breath, decreased lung function
• Swelling of the tongue
• Hoarse voice
• Sleep apnea
• High blood pressure
• High blood cholesterol levels

Many of these symptoms are associated with hypothyroidism, but it’s worth considering whether they are directly caused by the condition or are linked to an unhealthy diet and sedentary lifestyle.

Hypothyroidism diagnosis

After the age of 40, if you complain of fatigue, doctors often recommend a TSH test. A TSH reading higher than 4.5 is generally classified as abnormal, and a diagnosis of hypothyroidism is made. This is usually followed by a prescription for medication, turning you into a lifelong patient who sees a doctor twice a year.

However, some plant-based, whole-food (PBWF) doctors question this approach. They suggest that TSH levels below 8.0 should not be treated with medication but rather addressed through dietary modifications.

Hypothyroidism treatment

Two nutrients critical for thyroid health are iodine and selenium. In a typical Indian vegetarian diet, where 40-70% of calories come from dairy, oil, and sugar, deficiencies in these nutrients are common. It is essential to consume large amounts of green leafy vegetables, berries, nuts, and seeds to meet these requirements.

In my dietary recommendations, I always emphasize eating a variety of foods. That’s why I say:

“Eat everything you like and some that you don’t; variety is important.”

This is especially relevant for hypothyroidism because the best source of selenium is Brazil nuts, which may not be the most appetizing. It’s a good idea to eat one or two Brazil nuts each week. Walnuts are also a good source of selenium, and for most people, five walnuts a day should be sufficient.

Iodine is essential for the production of thyroid hormones, as the body cannot produce iodine on its own. Plant-based sources of iodine include:

• Whole grains
• Potatoes with skin
• Spinach, Kale and other leafy green vegetables
• Green peas and beans
• Zucchini
• Celery
• Cucumber
• Strawberries and other berries

Sea vegetables

Sea vegetables, which are leafy greens that grow underwater, are an excellent source of iodine. However, we Indians rarely include them in our diet. I encourage you to explore ways to incorporate these nutritious foods. They are commonly found in Japanese cuisine, particularly in sushi. Some popular examples include wakame salad, nori sheets, and kelp flakes. The recommended daily intake of iodine is 150 mcg, and just two sheets of nori can provide this amount. Vegetarian sushi is easy to prepare at home using ingredients like cucumber, avocado, and ginger.

Yoga for hypothyroidism

Reversing hypothyroidism can also be supported by practicing certain yoga postures that involve moving the legs above the shoulders and head, which increases blood flow to the thyroid and pituitary glands, stimulating them. Recommended asanas include:

1. Shirshasan (Headstand)

2. Sarvangasana (Shoulderstand)

3. Halasana (Plow Pose)

4. Karnpidasana (Ear Pressure Pose)

My Personal Experience

I have successfully cured my hypothyroidism, and many others have reported similar results. For further insights, I recommend watching Dr. McDougall’s video on this topic:
