Dr. Shi Guimei reply Nutrition

Hello! In cases of hyperthyroidism, it is important to provide adequate protein and caloric intake in the diet.
If the individual is underweight, a strategy of eating small, frequent meals is recommended.
Stimulants such as coffee, tea, alcohol, and tobacco should be avoided.
Additionally, the intake of milk can help compensate for calcium loss from the bones (it is advisable to drink 1 to 2 cups of milk daily, with each cup being 240cc).
Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

Managing hyperthyroidism through diet can be an essential part of treatment alongside medical interventions. Hyperthyroidism, characterized by an overactive thyroid gland producing excessive thyroid hormones, can lead to symptoms such as weight loss, increased heart rate, anxiety, and heat intolerance. While dietary changes alone cannot cure hyperthyroidism, they can help alleviate symptoms and support overall health.

Foods to Eat
1. High-Protein Foods: Since hyperthyroidism can lead to muscle loss, incorporating high-protein foods is crucial. Lean meats, poultry, fish, eggs, and dairy products are excellent sources of protein. Plant-based proteins such as legumes, nuts, and seeds can also be beneficial.

2. Whole Grains: Foods like brown rice, quinoa, oats, and whole grain bread provide essential carbohydrates and fiber, which can help maintain energy levels and support digestive health.

3. Fruits and Vegetables: A diet rich in fruits and vegetables can provide antioxidants and essential vitamins. Leafy greens, berries, and cruciferous vegetables (like broccoli and cauliflower) are particularly beneficial. These foods can help combat oxidative stress and inflammation.

4. Healthy Fats: Incorporating sources of healthy fats, such as avocados, olive oil, and fatty fish (like salmon), can support heart health, which is important as hyperthyroidism can increase heart rate and blood pressure.

5. Calcium and Vitamin D: Hyperthyroidism can lead to bone density loss, so it’s essential to include foods rich in calcium (like dairy products, leafy greens, and fortified foods) and vitamin D (from fatty fish, egg yolks, and fortified foods) to support bone health.

Foods to Avoid
1. Iodine-Rich Foods: Since iodine can stimulate thyroid hormone production, it’s advisable to limit foods high in iodine, such as seaweed, iodized salt, and certain seafood.

2. Caffeine and Stimulants: Caffeine can exacerbate symptoms like anxiety and palpitations. Therefore, it’s best to limit coffee, tea, energy drinks, and chocolate.

3. Processed Foods: Foods high in sugar and unhealthy fats can contribute to inflammation and should be minimized. This includes sugary snacks, fast food, and processed meats.

4. Cruciferous Vegetables (in large amounts): While these vegetables can be beneficial, consuming them in excessive amounts may interfere with thyroid function due to their goitrogenic properties. Moderation is key.

Lifestyle Factors
- Smoking and Alcohol: Both smoking and excessive alcohol consumption can negatively impact thyroid health. Smoking can worsen symptoms and increase the risk of complications, while alcohol can interfere with medication and exacerbate anxiety and mood swings. It’s advisable for individuals with hyperthyroidism to avoid smoking and limit alcohol intake.

Conclusion
In summary, while dietary changes can support the management of hyperthyroidism, they should be part of a comprehensive treatment plan that includes medical supervision. Encourage your boyfriend to consult with a healthcare provider or a registered dietitian who specializes in thyroid health for personalized dietary advice. Maintaining a balanced diet, avoiding excessive iodine, and steering clear of stimulants can help manage symptoms effectively. Additionally, adopting a healthy lifestyle that includes regular exercise, stress management, and avoiding harmful substances like tobacco and excessive alcohol will contribute to overall well-being.
