Eight Common Questions about Hyperthyroidism Diet

1. Why do you need iodine ban if you have hyperthyroidism?

In patients with hyperthyroidism, thyroid hormone is already excessive.

Iodine is the basic raw material for the synthesis of thyroid hormone. Limiting the intake of iodine can reduce the synthesis of thyroid hormone from the source.

Air, drinking water and food all contain iodine, so it is not realistic to ban it absolutely, but the following three points can greatly reduce iodine intake:

(1) Fasting high iodine foods, such as various seafood, including kelp, laver, mussel, etc.

(2) Avoid iodized salt and buy non-iodized salt instead.

(3) Avoid unnecessary iodine intake, for example, do not use iodine-containing drugs, cosmetics, etc.

2. Why do you always feel hungry after getting hyperthyroidism?

People with hyperthyroidism secrete more thyroid hormones, which can promote the metabolism of the body’s three major nutrients (carbohydrate, protein and fat), accelerate decomposition, increase the body’s heat production and heat dissipation, and increase the body’s basal metabolic rate.

In short, eating the same amount of food, but consuming more than before, makes it easier to get hungry.

For example, if you compare a person to a mobile phone, eating is the process of charging, and the basal metabolic rate of the human body can be understood as the power consumption speed of the mobile phone in the standby state. Hyperthyroidism patients consume electricity faster than normal people in the [standby] state, so eating the same amount of food makes hyperthyroidism patients more likely to consume electricity and more likely to be hungry.

Therefore, one of the nutritional treatment principles for hyperthyroidism is high calorie. When hyperthyroidism is not well controlled, side meals can be appropriately added.

Can I have an extra meal when I am hungry? Will you get fat?


For hyperthyroidism patients, because the body needs more energy and needs to eat more food than usual, the system of three meals and three points can be adopted, that is, one meal can be added about 2-3 hours after the meal to meet the body’s demand for energy and nutrients.

However, it should be noted that when choosing food, spicy food should be avoided so as not to stimulate patients and lead to aggravation of hyperhidrosis, palpitation, etc.

The common manifestation of hyperthyroidism patients is emaciation. It is difficult to get fat due to increased consumption and poor digestion and absorption of hyperthyroidism patients.

However, if hyperthyroidism has been controlled and the previous diet is followed without reducing the amount of diet and side meals, it is likely to become fatter.

4. Always diarrhea, how should diet be adjusted?

For hyperthyroidism patients, due to accelerated gastrointestinal peristalsis and poor digestion and absorption, stool will often increase and even diarrhea will occur.

At this time, avoid eating foods rich in dietary fiber, such as various crude fiber vegetables. Instead, you should choose tomatoes, tender cucumbers, vegetable melons, tender loofah and other vegetables with less crude fiber.

5. How much water do you need to drink every day if you have hyperthyroidism?

Hyperthyroidism patients sweat a lot, metabolize vigorously and consume a lot of water. Hyperthyroidism patients should ensure 1,500 ~ 3,000 milliliters of water every day.

At the same time, it is necessary to remind us not to drink coffee, tea and other irritating beverages, so as not to aggravate the symptoms of palpitation, fear of heat and irritability.

6. How much meat, eggs, milk (protein) are appropriate for hyperthyroidism patients to eat every day?

For hyperthyroidism patients, due to vigorous metabolism in the body, the demand for protein is higher than that of the average person. 1.5 grams of protein should be provided per kilogram of body weight per day.

For example, if you weigh 60kg, you need to eat 60 × 1.5 = 90g of protein every day.

7. Do hyperthyroidism need additional vitamins and minerals?

Due to the rapid metabolism of hyperthyroidism patients, the demand for vitamins and minerals has also increased greatly, and sufficient vitamins and minerals need to be provided to meet the needs of the body. For example:

    Energy metabolism is vigorous, The demand for B vitamins has increased, You need to eat more cereals, meat, milk and bean products. Increased metabolism also requires vitamin C supplementation. Such as all kinds of fresh vegetables and fruits. Vitamin D can affect calcium metabolism, Osteoporosis often occurs in hyperthyroidism patients, so adequate vitamin D should be provided, and calcium and phosphorus should be paid attention to at the same time. In order to avoid hypokalemia or periodic paralysis caused by potassium deficiency in hyperthyroidism patients, potassium intake should be ensured, and potassium-rich soybeans and bean products, bananas, etc. can be eaten more.

8. Can preserved fish, preserved meat and pickled products be eaten?

It is best not to eat it. Because cured fish, cured meat and pickled products need a large amount of salt in the production process, and most of them are iodized salt, the iodine content in these foods is relatively high.

For example, the iodine content of Cantonese sausages is equivalent to that of shrimps, and the iodine content of almond pickles is not low, which is more than three times higher than that of shrimps.

It is very difficult for us to distinguish the iodine content of each kind of cured fish, cured meat and pickled products by specific varieties and appearance. To be on the safe side, it is better not to eat it.
