What should be the diet in case of thyroid disorder?

Diet plays a crucial role in managing thyroid disorders. Depending on whether the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism), dietary adjustments can help support thyroid function and overall well-being. Here's a breakdown of dietary recommendations for both conditions:

---

Diet for Hypothyroidism (Underactive Thyroid)

1. Include Foods Rich in Iodine

• Why: Iodine is essential for thyroid hormone production.
• Sources:
  • Iodized salt
  • Seaweed (kelp, nori)
  • Dairy products (yogurt, milk, cheese)
  • Fish (cod, shrimp, tuna)
  • Eggs

2. Focus on Selenium-Rich Foods

• Why: Selenium supports thyroid hormone production and protects the thyroid gland from oxidative damage.
• Sources:
  • Brazil nuts
  • Sunflower seeds
  • Chicken
  • Fish (tuna, sardines)
  • Brown rice

3. Get Enough Zinc

• Why: Zinc is essential for the production of thyroid hormones.
• Sources:
  • Oysters
  • Beef
  • Pumpkin seeds
  • Lentils
  • Chickpeas

4. Add Foods Rich in Fiber

• Why: Hypothyroidism can cause constipation; fiber helps with digestion.
• Sources:
  • Whole grains (oats, quinoa, brown rice)
  • Vegetables (broccoli, carrots, spinach)
  • Fruits (apples, pears, berries)
  • Legumes (beans, lentils)

5. Watch Out for Goitrogens

• Why: Goitrogens can interfere with thyroid function, especially in raw forms.
• Foods to Limit (Cook to Reduce Impact):
  • Cruciferous vegetables: Broccoli, cauliflower, cabbage, kale, and Brussels sprouts
  • Soy products: Tofu, soy milk
  • Peanuts, pine nuts

6. Healthy Fats

• Why: Good fats support hormone production and overall cellular health.
• Sources:
  • Olive oil
  • Avocados
  • Fatty fish (salmon, mackerel)
  • Nuts and seeds (walnuts, flaxseeds)

7. Limit Sugars and Processed Foods

• Why: Hypothyroidism can slow metabolism, leading to weight gain. Processed foods and sugars can further disrupt metabolism.
• Avoid: Sugary snacks, refined grains, processed meats, and fast foods.

Diet for Hyperthyroidism (Overactive Thyroid)

1. Increase Calcium and Vitamin D Intake

• Why: Hyperthyroidism can lead to bone thinning, so it's important to support bone health.
• Sources of Calcium:
  • Dairy products (milk, cheese, yogurt)
  • Leafy greens (kale, collard greens)
  • Almonds
  • Sardines
• Sources of Vitamin D:
  • Fatty fish (salmon, mackerel)
  • Fortified foods (orange juice, dairy, cereals)
  • Egg yolks
  • Exposure to sunlight

2. Limit Iodine-Rich Foods

• Why: Excess iodine can exacerbate hyperthyroidism.
• Avoid or Limit:
  • Seaweed and kelp
  • Iodized salt
  • Shellfish
  • Iodine supplements

3. Goitrogens Are Beneficial

• Why: Unlike hypothyroidism, goitrogens can help reduce thyroid hormone production in hyperthyroidism.
• Include:
  • Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts)
  • Spinach
  • Peaches and pears
  • Soy-based foods (tofu, soy milk)

4. Increase Protein Intake

• Why: Hyperthyroidism can cause muscle loss and weight loss, so it's important to maintain muscle mass.
• Sources:
  • Lean meats (chicken, turkey)
  • Fish
  • Eggs
  • Legumes and beans
  • Greek yogurt

5. Avoid Stimulants

• Why: Stimulants like caffeine can worsen symptoms of hyperthyroidism, such as restlessness, anxiety, and palpitations.
• Limit:
  • Coffee, tea, soda
  • Energy drinks
  • Chocolate

6. Anti-inflammatory Foods

• Why: These help manage inflammation in the body, which can be elevated in thyroid disorders.
• Sources:
  • Berries (blueberries, strawberries)
  • Turmeric
  • Fatty fish (salmon, tuna)
  • Olive oil

General Tips for Both Thyroid Conditions

• Stay Hydrated: Drink plenty of water throughout the day to support overall health and proper digestion.
• Regular Meals: Eating balanced meals at regular intervals can help maintain stable energy levels and support metabolism.
• Avoid Processed Foods: Processed foods are often high in sodium, sugar, and unhealthy fats, which can interfere with thyroid function.
• Consult a Doctor: Always consult a healthcare professional before making any major dietary changes, especially if taking thyroid medications.

With these dietary changes, managing thyroid issues can become easier and more effective, complementing medical treatments.
