Which nutrients are important for thyroid?

The three most important nutrients are important for optimal thyroid health. These are

                          1. Iodine 
                          2. Selenium
                          3. Zinc

Role of Iodine in thyroid function

Iodine is an essential micronutrient. It plays a very crucial role in the synthesis of thyroid hormones, thyroxine T4 (4 iodine atom) and triiodothyronine T3 (3 iodine atom). It is required in very fewer amounts that are essential for the human body as many reactions are dependant on iodine. The normal blood level is around 8-12 micrograms/dl. The best sources are seafood like sea fish, sea salt, and cod liver oil.  Small quantity is also found in milk, meat, vegetables, cereals. Freshwater iodine content is around 1-50 micrograms/liter. The daily iodine requirement for an adult is 150 micrograms per day. The requirement is increased in pregnancy up to 250 micrograms per day.

Role of zinc in thyroid function

Zinc is a component of many enzymes (more than 300 enzymes). Zinc is required for the synthesis of insulin by the pancreas and helps in immunity enhancement. The normal level of zinc in the blood is 96 micrograms per 100ml in healthy adults. The average adult body zinc level is 1.4 to 3 grams of zinc. Good sources of zinc are meat, milk, and fish.

Which nutrients are harmful to the thyroid?

Goitrogens – are chemical substances that are involved in the development of goiter. It interferes with iodine uptake by the thyroid hormone. It is widely available in food and water. The cruciferous group of food may contain Goitrogens. These include cabbage, cauliflower, and broccoli. 

Cyanoglycosides and thiocyanates are other goitrogens which are found in dairy products.

Foods rich in Goitrogens

  3. Fruits – strawberries, peaches, pears, and strawberries, etc.
  4. Starchy plants – sweet potatoes, cassava, peaches, etc.
  5. Seeds and Nuts – millet, pine nuts, peanuts, etc.

If you are diagnosed with hypothyroidism then you should avoid or take the fewer amount of cooked goitrogenic foods. Take plenty of iodine-rich foods. Some research says goitrogens may inactivate after cooking so you can take in moderation.

According to some studies, pearl millet might interfere with thyroid function, even in absence of an iodine deficiency.

What a thyroid patient should not eat?

As discussed earlier, you can consume properly cooked foods that contain goitrogens. Hypothyroid people usually gain weight so, highly processed foods are generally unsafe as it contains a lot of calories. 

Say no to these foods and supplements:

  1. Millets – all varieties
  2. Highly processed foods – Bakery products like cakes, cookies, hot dogs, etc.
  3. Supplements – Taking a high amount of zinc and selenium may result in some unwanted side-effects so try to consume it with food.

Why people gain weight in hypothyroidism?

The mechanism of weight gain in hypothyroid individuals is very complex. To understand this first learn Basal metabolic rate. It is the energy utilized by an individual at rest in fasting state and at thermoneutral temperature. This energy is utilized to sustain normal cells and keep organ functioning within the body. It accounts for approximately 60–75% of total daily energy expenditure in individuals with a sedentary lifestyle.

In thyroid patients, BMR is decreased. When a patient is consuming a high-calorie diet with decreased BMR, some weight gain occurs. 

More weight gain is associated with more severe hypothyroidism. It may not be associated with excess fat accumulation.

salt and water retention is the most common cause of weight gain in these individuals. Many studies have found that massive weight gain is rarely associated with hypothyroidism. In general, 2.5-4.5 kg of body weight gain may be attributable to the thyroid.  

If an individual presents with only symptoms of weight gain, it is less likely that the weight gain is only due to the thyroid abnormalities.

Tips for maintaining a healthy weight in hypothyroidism

Disturbed metabolism may cause weight gain in hypothyroid individuals. These are a few useful tips to maintain a healthy weight. 

  1. Adopt a habit of low to moderate carb diet – Low to moderate carb diet helps in losing weight. Avoid too low carb diet as it may decrease the level of thyroid hormone. One study reported thyroid hormone deficiency in an epileptic patient when he was treated with a keto diet. The thyroid hormone should be monitored regularly if you are starting a keto diet.
  2. Try yoga or meditation – It helps in relieving stress and weight loss.
  3. Love what you eat – Adopt a habit of mindful eating. Always try to answer yourself what, why, how fast you are eating. Establishing a good bond with food that you are eating often helps in weight loss. It helps to understand how much you are eating. These habits always help in checking high calorie food. 
  4. Get plenty of rest – At dietplusminus, it is advised that you should take at least 6-8 hours of sleep every night. Less sleep or poor quality sleep is associated with weight gain.
