Cauliflower

I have heard Cauliflower can be bad for hypothyroidism?

What effect does it have on TSH, FT4 and FT3 levels?

[Super_sally888]

Certain vegetables can suppress thyroid if eaten in excessive quantities; these include cabbage, cauliflower and broccoli.

However, when eaten in normal quantities these vegetables are not a concern and in fact are very nutritious when part of a healthy and varied diet.  Please do not avoid eating these vegetables.

Of more concern is soy.  Soy products have a much stronger thyroid suppressing effect than the above vegetables and should be avoided or strictly limited if thyroid function could be a concern.

If they suppress thyroid hormones, does that also mean they'll keep TSH within range?
