What does thyroid like and dislike?

As a continuation of the previous article concerning weakening of thyroid, we already know that chronic stress in a form of starvation, rash diets, long-lasting aerobics, sleep deprivation, lack of relaxation or recovery, may lead to thyroid disorders, and, in reality, to the disorder of the whole hormonal system and adrenal glands. In this article I will include the information of the things thyroid likes and dislikes. How to prevent from weakening this organ and how to react when it already happened.

You should definitely read:

Tricky thyroid, how does it all begin?

Let's start with the factors, which may disturb the efficiency of this organ.

Tricky thyroid, how does it all begin?

Thyroid produces 93% of T4 hormone, which is inactive, and only 7% of T3. If we have no problems with converting T4 into T3, there's big chance that letrox or euthyrox will be enough. Unfortunately, many factors, such as stress, nutritional deficiency, contraceptive pills, alcohol, or diabetes, cause the disorder of conversion of T4 into T3.

As a result, we have a lot of T4 in blood and a little of T3, therefore, the symptoms of hypothyroidism occur, despite medical treatment.

Too low calorific supply, together with too low content od carbohydrates in diet.

Thyroid needs carbohydrates to function properly. If you have problems with this organ, I dissuade any low-carb diets.

Before workout products, burners, energisers, such as Red Bull, coffee

Any kind of stimulating substances influence negatively the functioning of thyroid gland. Therefore, such products should be limited, or totally eliminated.


Resigning from gluten may cause a lot of good things. The matter of avoiding it is specifically important in case of autoimmune cause of hypothyroidism (e.g. Hashimoto). The reason is that autoimmune diseases are often connected with leaking intestines. Eating gluten may exacerbate the defense reactions of the body and e.g. increase the level of anti-bodies in blood.


These are the chemical compounds occurring in food. They disturb the absorption of iodine by the body. These compounds are present mainly in vegetables, such as broccoli, cauliflower, various kinds of cabbage, brussel sprouts, as well as in legumes, such as soya or peanuts.

However, it does not mean that you should definitely resign from eating broccoli or cauliflower. But you should keep restraint and remember to consume these vegetables only after cooking, that's when part of goitrogens is reduced.


You should not let yourself be overtrained, because it also weakens the effectiveness of thyroid. Remember about the importance of recovery time.

Lack of sleep

Proper amount of sleep is precious, that's why we should never belittle it.

When checking the thyroid hormones after a night with small amount of sleep, you may get wrong results of tests, because on that day the thyroid will be in worse condition.

What will thyroid be thankful for?

Of course, everything that results from the things the thyroid doesn't like, which is proper amount of sleep, caring about recovery, sufficient amount of calories and carbohydrates. Also limiting stressful situations to minimum is good.

What else?

We can also help ourselves by introducing the following products in our diet:

Brazil nuts – rich in selenium. <Selenium is indispensable for the proper synthesis, activation and metabolism of thyroid hormones.>

Coconut oil – it contains vitamin B2, B6, C and E, as well as folic acid, potassium, calcium, magnesium, phosphorus, iron, sodium and zinc. Vitamins B2, B6, C and E foster the production of thyroid hormones.

Seaweed – spirulina, bladder-wrack, chlorella.

We should take care of the health of our intestines and appropriate bacterial flora. Natural probiotics in a form of pickled vegetables, as well as linseed and natural apple vinegar (which can be added to salads) are a good help here.

It's also good to use the zinc and magnesium supplements. Proper level of iron, ferritin, vitamin D3 and B12 is also crucial. If needed, use appropriate supplementation.

The diet has to be balanced.

It's very important to provide proper supply of protein, which should originate from meat, including beef, venison, as well as whole eggs and sea fish.

Fat should come from the coconut oil and brazil nuts, but also from fatty sea fish, yolks, butter, almonds, olive oil and avocado.

The sources of carbohydrates should be fruit and vegetables, but also gluten-free grains, such as buckwheat, millet, sweet potatoes, amaranth and quinoa.

Remember, that problems with thyroid have some reason. Prescribing synthetic hormones without knowing the reason of lack of efficiency of this organ causes that after short period of improvement, the ailments occur again, despite perfect levels of hormones in blood. In such situation, the change of lifestyle is crucial, along with different nutrition, and remembering about the fact, that stress is one of the most important factors, which influence worse functioning of the thyroid.
