Nutrition and Thyroid Health

How does our diet affect our thyroid?

Our diet plays an important role in keeping our thyroid healthy and ensuring it functions well. Iodine is the chemical element responsible for making the 2 thyroid hormones, T4 and T3. Some foods that are rich in iodine are:
• Strawberries
• Cranberries
• Potatoes
• Yoghurt
• Iodine supplements

Food sensitivities

People who are sensitive to wheat and gluten are known to commonly develop thyroid disorder due to an inflamed thyroid. Soy products can inhibit thyroid hormone absorption and can sometimes cause a weaker immune system.

The world of vitamins and minerals

Vitamins and minerals in our diet are directly linked to a healthy thyroid. Diets that lack in these can cause thyroid deficiency and if an individual has a thyroid disease, vitamins and minerals that are consumed may not be absorbed by the body very well.

People who are vegan or vegetarian have a risk of developing thyroid disease if they don’t consume enough protein.

Vitamin A

Vitamin A is needed to activate cells to increase metabolic rates and energy levels.

Vitamin B complex

The vitamin B complex is needed for good thyroid function
• B1 is needed to treat an overactive thyroid
• Lack of B2 suppresses thyroid function, failing to secrete hormones from the adrenal and thyroid glands
• Lack of B12 can cause neurological diseases. People who have an underactive thyroid or don’t have one at all fail to absorb B12.

Vitamin C

People with a vitamin C deficiency can have an overactive thyroid which secretes too much hormone, so constantly needing more vitamin C in their diet.

Vitamin D

Taking vitamin D counteracts the development of osteoporosis, a bone disease.


Calcium and magnesium are needed for optimal thyroid health. Selenium and zinc are needed to convert T4 to T3. If selenium is not present, organs will function as if they were hypothyroid as less T3 is being produced.

Importance of diet

It is important to eat foods that are organic and non-processed such as fruits, vegetables, nuts and seeds. Eliminating foods full of trans-fats, artificial sweeteners, fried food and decreasing the number of goitrogenic foods is necessary.

What is the link between thyroid dysfunction and obesity?

Thyroid dysfunction has also been associated with obesity as low thyroid levels cause an increase in weight, decrease in metabolic activity and body temperature (thermogenesis).
