What is Hypothyroidism?
Hypothyroidism is a medical condition where a person has an under active thyroid gland and your thyroid gland doesn`t produce required hormones. The thyroid gland is a small gland located on the front side of your neck just below your Adam’s apple. This is a butterfly shaped gland which is responsible for regulating your body metabolism . The thyroid hormones regulates metabolism for every cell of your body .
Cause of Hypothyroidism
The condition of hypothyroidism is mainly caused due to the Hashimoto`s disease. A Hashimoto disease is an autoimmune disease where your body produces antibodies that attack its own tissues. Around 90% cases of Hypothyroidism are the causes of this disease .
The rest 10% cases of hypothyroidism can be counted under the cause of certain medications, radiation therapy, and hyperthyroidism treatment. It can also be the case when you are not consuming enough iodine. Iodine is required by your body for release of thyroid hormones.
Symptoms of Hypothyroidism
The condition of hypothyroidism slows down your metabolism to a point where you always feel tired, lethargic and out of energy. However, the symptoms of hypothyroidism vary for different individuals. It depends upon your deficiency of thyroid hormone in the body. The Hypothyroidism symptoms includes
1. Feeling of continued tiredness
If you are experiencing a continued tiredness during their whole day, get your thyroid test done. Fatigue is the prime symptom diagnosed in the hypothyroidism patients . You may feel sleepy during your whole day if you are down with hypothyroidism.
2. Weakness in your body
The patients of hypothyroidism experience tingling and numbness in their arms and legs. You would complain about weakness in your muscles if you are suffering from hypothyroidism. The weakness in your body is caused by catabolic metabolism which is a result of hypothyroidism. During such a metabolism, your body is breaking down your muscle tissues in lieu of producing energy.
3. Mental fatigue and depression
The symptoms of mental fatigue and depression are common in hypothyroidism patients . You can count this depression as a result of loss of energy and deterioration of health.
4. Feeling colder
The patients struggling with the condition of hypothyroidism has a weak BMR and their body then burn less calories. Less calories means less heat and you end up feeling colder. Hypothyroidism also affects the brown adipose tissue of your body. It prevents the brown adipose tissue to maintain your body heat especially in cold weather. However, the cause of hypothyroidism on brown adipose tissue is still under research phase. 
5. Irregular and heavy periods
The woman suffering from hypothyroidism is likely to experience irregular periods with a heavy flow  . The problem of abnormal menstruation periods in hypothyroidism is linked to Thyrotropin releasing hormone (TRH). A thyroid dysfunction leads to alteration in various hormone levels including prolactin, gondatropin releasing hormone, and sex hormone-binding globulin which contributes to your menstruation abnormalities .
If you are suffering from hypothyroidism, taking right dietary approach will help you deal with your situation. You need to modify your diet by including the right foods and excluding the wrong foods from your diet.
The best foods to eat in Hypothyroidism diet
The best foods you should consume in your hypothyroidism diet should include these 4 specific nutrients namely
Iodine is an important nutrient responsible for production of thyroid hormone. The thyroid gland produces two hormones namely T3 and T4 by using iodine from food . Therefore, you should consume right amounts of iodine in your diet for optimal thyroid function.
Also, too much iodine can also do harm in your condition. Your daily intake of iodine should be at 150 mcg per day . However, it is always a good idea that you talk with your doctor for the dose of iodine in hypothyroidism.
The second important nutrient for optimal thyroid function is selenium. The selenium is responsible for conversion of T4 into T3. The thyroid gland of your body contains selenium which removes iodine molecules from T4 thereby converting it into T3. When the patients suffering from thyroid conditions tested for selenium levels, they have fewer levels as compared to normal levels.
The daily RDA for selenium is at 55 mcg and 400 mcg being the upper limit . You can aim for RDA of selenium by your daily diet if you are eating a balanced diet.
· Zinc and Copper
Zinc and copper forms an important link for a good thyroid health. These minerals together share an important relationship for your thyroid function. The most important element at first glance for thyroid health is zinc, which is responsible for conversion of T4 into T3. But, if you dig further, copper is also needed for proper zinc and copper balance in your body.
The copper is needed by body to protect itself from too much T3 in the blood. So a proper ratio of zinc to copper is required by the body to maintain its health. Also, if you take zinc alone in your diet, the bioavailability of copper can get disturbed . The RDA of zinc is at 8 mg per day for women and 11 mg for men . You should consume zinc and copper in the ratio of 8:1

The worst foods to eat in hypothyroidism diet
The worst foods that can affect your thyroid health will primarily consist of these 3 below mentioned ingredients. Avoiding these foods in a hypothyroidism diet can help you aim for a better thyroid health.
· Foods containing Gluten
Gluten sensitivity can be a notable factor when your thyroid health is concerned. Eliminating gluten completely from your diet can improve your thyroid function. Patients suffering from Hashimotos disease has shown to be gluten intolerant. Consumption of gluten in Hashimotos disease can trigger an autoimmune response which can attack your thyroid gland making it worse .
· Goitrogenic Foods
Goitrogenic foods have a negative impact on your thyroid health. They can disturb the normal functioning of your thyroid gland by reducing how the thyroid gland uptakes iodine . This problem can lead you to suffer from goiter, a condition where your thyroid gland becomes enlarged . So, it is always advised by your doctor to eliminate goitrogenic foods from your hypothyroidism diet.
· Cruciferous Vegetables
Crucuiferous vegetables are the most nutrient loaded vegetables on the planet. But there are many debates on using cruciferous vegetables in hypothyroidism diet. Cruciferous vegetables contain glucosinolates which metabolize into isothyiocyanates. These isothyiocyanates have numerous health benefits including detox and anti cancer properties .
But the concern on using crucifier vegetables is that they also possess goitrogenic properties which can affect your thyroid health. However, the amounts of goitrogenic properties vary in different crucifiers. Also, there is no actual study that can claim the bad effect of using cruciferous vegetables in hypothyroidism diet. In our opinion, you should not avoid eating cruciferous vegetables. Rather, you should eat them in moderation to avail all the health benefits.
A notable case here is that, if you are suffering from hypothyroidism only due to iodine deficiency then you should definitely limit the consumption of crucifiers. Because the goitrogens contained in crucifiers can mess with your thyroid health. But if you are among the 95% cases of hypothyroidism which are the result of only auto immune disorder or hashimotos thyroiditis, you should definitely consider eating crucifiers to avail benefits to your digestive system.
Also, if you are eating cruciferous vegetables, try not to eat them in raw form. Instead cook them to reduce their goitrogenic properties.
