Most goitrogens are naturally-occurring chemicals that are ingested in foods or drugs. These chemicals can interfere with thyroid function in different ways. Some compounds induce antibodies that cross-react with the thyroid gland; others interfere with
thyroid peroxidase (TPO), the enzyme responsible for adding iodine during production of thyroid hormones. Either way, the thyroid isn�t able to produce as many of the hormones that are needed for regulating metabolism (see my article on nutrition and thyroid health for more on how this works).
For people with healthy thyroid function, the thyroid simply compensates and makes more of the hormones as they�re called for. But in some people whose thyroid function is already compromised, the thyroid gland may actually grow more cells as it tries to make up for inadequate hormone production, eventually forming a
goiter (a swelling or enlargement of the thyroid gland).

I�m always dismayed when women are told they have to avoid a healthy food when there isn�t a very good reason for it (a food allergy, for instance). It would be a shame if women with thyroid problems avoided these goitrogenic foods altogether, because most of what I�ve listed above contain beneficial micronutrients and have strong value as healthy foods that support digestive, skeletal, cardiovascular, and immune function. It just doesn�t make sense to deny the rest of our body the benefits of these foods when the threat they pose to our thyroid is so slight and can be eliminated so easily! So I suggest that we all use a little common sense when it comes to goitrogens and our thyroids �
steam, cook, or ferment your vegetables to reduce the goitrogenic compounds, rotate your choices so that you�re not eating the same foods every day, and above all, enjoy them as part of a richly varied diet of wholesome foods.
Here are some examples of goitrogens:
� Broccoli
� Cauliflower
� Kale
� Brussels Sprouts
� Cabbage
� Mustard Greens
� Radishes
� Spinach
� Strawberries
� Peaches
� Soy-Based Foods
� Peanuts
