I have mild hypothyroid (I recently started taking Synthroid .5) and heard it was bad to eat large quantities of vegetables like broccoli and cauliflower. What is a large quantity? Is it an absorbtion issue? Can I have a side of broccoli with dinner without messing up my intake of the synthroid? My doctor seems to be ok with having cereal with milk an hour after taking it (calcium inhibits the absorbtion too) so should I just relax about this too?
If the broccoli is cooked there is no problem. You have to be careful with raw broccoli and cauliflower as well as some other vegestable because they contain goitrogens in the raw state, but cooked is o.k. If you eat them raw just be sure to not eat large portions, just small amounts.
I wouldn't eat it more than once a day raw and maybe only a couple times a week and just a small portion. I would think no more than 3 flowerettes (is that what their called). If you notice that you have more hypo symtpoms when eating this amount you may have to cut it out entirely. Remember though that cooked they are o.k.
I think there is a full list of goitrogen containing foods in the "Informative Archives".
