Thyroid Diet: What to Eat and Avoid for Better Thyroid Health

Your thyroid gland plays a key role in regulating metabolism, energy levels, body temperature, and hormone balance. When the thyroid becomes underactive (hypothyroidism), you may experience fatigue, weight gain, dry skin, constipation, hair loss, and mood changes. While medication is essential for most people, diet also plays a supportive role.

A thoughtful thyroid diet can help boost nutrient intake, reduce symptoms, and support better thyroid function. Knowing what to eat and what to avoid can make a noticeable difference in how you feel.

H2: Best Diet for Hypothyroidism

There isn’t one “magic diet,” but several eating patterns work well as diets for hypothyroidism because they reduce inflammation and supply essential nutrients. These include:

• A balanced whole-food diet
• Anti-inflammatory diet
• Mediterranean-style diet
• High-fiber, nutrient-rich meals
• Limited processed foods and added sugars

The best diet for hypothyroidism is one that focuses on whole foods, lean proteins, healthy fats, and minerals like iodine, selenium, and zinc.

H2: Practical Diet Tips for Better Thyroid Health

Here’s how you can put your thyroid diet into action:

Wait at least 30–60 minutes before eating or drinking coffee.

?? Plan Balanced Plates

Include a mix of protein, fiber, and healthy fats in every meal.

Water supports digestion, metabolism, and hormone function.

?? Cook Goitrogenic Vegetables

If you enjoy cruciferous vegetables, cooking them helps reduce their impact on the thyroid.

These can worsen inflammation and fatigue.

Fish, walnuts, and flaxseeds help reduce inflammation naturally.

Hypothyroidism can slow metabolism, so portion awareness is helpful.
