    this isnt really related, but how does this make you feel? makes me a little queezy

    • Michael Greger M.D.

      Thanks for pointing that out–do you want to repost that comment in one of the organic foods videos? Maybe in Can Pesticides Be Rinsed Off? That way people interested in organics won’t miss out on your post!

  • Dr Greger I have a friend who drinks low fat soy milk at home but skim milk cappuccinos when out because she is worried that the full fat soy milk they have at cafes has too much fat (she is watching her weight).
    What can I tell her?

  • Eric Needs

    i will!

    Dr. Greger, I’m a pregnant vegan taking a prenatal vitamin that supplies 150 mcg of iodine. Am I still at risk for deficiency? Thank you!

    • Toxins

      As the good doc pointed out, prenatal vitamins have folic acid and iron which may harm your baby.

    My bride and I very, very seldom add “salt” to our foods. to supplement our iodine intake, we take “sea kelp”. Don :-))

      Hi Don, I hope all is well with you and your family, more than nine months later! I eat kelp occassionally but only recently learned it has enormous quantities of iodine. From the numbers I’ve seen 100g dried kelp can have about 60 000 mcg of iodine (not quite a fatal dose, but way over the recommended upper limit). I’ve chopped my dried kelp into hundreds of stamp sized strips for a daily tab. I also soak the kelp a bit before using to remove the occassional ‘crunch’. I assume that lowers the salt content but probably not the iodine.

    Dear Dr. Greger,
    I am 4 weeks pregnant and i’m vegan. I have watched your videos and I am concerned about iodine and vitamin B12. I eat a healthy varied diet of fruits, vegetables, nuts, beans and other legumes.
    Should I start taking vitamin B12 and iodine supplements? What do you suggest?
    Thank you

    Dear Doctor Greger, do you have any data on whether alcohol free beer is safe during pregnancy? The data in internet is quite contradictory. Many thanks in advance.

  • Technus

    What about cranberries, seaweed or baked potatoes, aren’t those good sources of iodine? I will probably start eating cranberries everyday again like I used to.

    I’m currently vegan and 10 weeks pregnant. A vegan nutritionist told me about iodine supplementation. When i mentioned it to my endocrinologist (i have hashimoto’s thyroiditis) , he said that her information was completely false and the supplements wouod kill off my thyroid even more. (The nutritionnist coaimed the opposite, that my dose requirement of synthroid wouod go down).
    Who’s right? I don’t want to harm my baby or my thyroid!! How likely will i have caused cretinism in my baby since i listened to the endocrinologist so far? :(
    Thank you

      How did you and your baby fare?
