Understanding Thyroid Disorders

The thyroid is a small, butterfly-shaped gland in the neck that regulates metabolism, energy levels, weight, digestion, mood, and hormonal balance.

The most common thyroid conditions include:

 Hypothyroidism

A condition where the thyroid gland produces less thyroid hormone, leading to:

• Weight gain

• Fatigue

• Hair fall

• Constipation

• Cold sensitivity

• Depression

 Hyperthyroidism

A condition where excess thyroid hormone is produced, causing:

• Weight loss

• Anxiety

• Palpitations

• Heat intolerance

• Muscle weakness

While medication is essential, diet plays a powerful supporting role in stabilizing hormone levels and reducing symptoms.

Why Diet Matters in Thyroid Management

According to Dt. Poonam Sharma, thyroid patients often eat “healthy” but still struggle because:

• They consume thyroid-interfering foods unknowingly

• Their diet lacks key micronutrients

• They follow extreme calorie restriction

A well-planned thyroid diet:
 Supports hormone production
 Improves metabolism
 Reduces inflammation
 Controls weight naturally
 Improves energy and digestion

 Thyroid Diet: Foods to Eat

1. Iodine-Rich Foods (In Moderation)

Iodine is essential for thyroid hormone production.

Best Indian Sources:

• Iodized salt (limited quantity)

• Dairy products

• Paneer

• Curd

Excess iodine can be harmful—balance is key.

---

2. Selenium-Rich Foods

Selenium helps convert inactive thyroid hormone (T4) into active form (T3).

Include:

• Brazil nuts (1–2 per day)

• Sunflower seeds

• Whole grains

• Mushrooms

---

3. Zinc-Rich Foods

Zinc supports immunity and hormone balance.

Good Sources:

• Pumpkin seeds

• Chana

• Lentils

• Nuts

---

4. Protein-Rich Foods

Protein supports metabolism and prevents muscle loss.

Best Options:

• Dals & legumes

• Paneer & tofu

• Eggs

• Lean meats (if non-vegetarian)

---

5. Anti-Inflammatory Foods

Inflammation worsens thyroid symptoms.

Add:

• Turmeric

• Ginger

• Berries

• Amla

• Green leafy vegetables

---

6. Fiber-Rich Foods (Balanced Intake)

Helps manage constipation and weight.

Examples:

• Oats

• Vegetables

• Fruits

• Flaxseeds

---

 Foods to Avoid in Thyroid

1. Excess Soy & Soy Products

Soy can interfere with thyroid hormone absorption.

 Soy milk
 Soy chunks (frequent use)

 Occasional intake is fine if properly spaced from medication.

---

2. Raw Goitrogenic Vegetables (Excess)

These interfere with iodine absorption when eaten raw.

 Raw cabbage
 Cauliflower
 Broccoli

 Cooked versions are safer.

---

3. Highly Processed Foods

Increase inflammation and worsen fatigue.

 Packaged snacks
 Fried foods
 Bakery items

---

4. Excess Sugar & Refined Carbs

Lead to weight gain and insulin resistance.

 White bread
 Sugary desserts
 Soft drinks

---

5. Excess Caffeine

Can worsen anxiety and palpitations.

 Too much tea or coffee

 Limit to 1 cup per day.

---

Common Diet Mistakes Thyroid Patients Make

 Skipping meals
 Eating too little in fear of weight gain
 Blindly following internet diets
 Not timing thyroid medication correctly
 Ignoring gut health

Dt. Poonam Sharma emphasizes that starvation diets slow metabolism further, making thyroid symptoms worse.
