: : i have been reading that taking soy can cause hypothryoid. i know it is still under scrunity but i am still wondering. i want to take revival, i think all of you know what that is, it is a soy shake with 160 mgs of soy. it is good for perimenopause symptoms. i am also perimenopausal, i have been diagnosed with hypothyroid and i havent taken any soy products yet. i am not on med yet either so i am wondering if it will interfere with the hypothyroid or if they think it will cause hypothyroid. does anyone know? thank you for any help.
: Hi Harley,
: This is from Mary Shomon's newletter "sticking our necks out" this month
: "BE VERY CAREFUL ABOUT REVIVAL SOY, PROMENSIL & OTHER ISOFLAVONE- HEAVY
: Major marketing efforts are targeting doctors and consumers with the soy
: "shake" known as Revival Soy, which delivers in one serving six times
: the amount of isoflavones you would find in a typical serving size of a
: soy food. There are serious concerns about this concentrated level of
: isoflavones, in terms of its ability to trigger thyroid problems. We
: know that soy has some positive benefits, but what do even the most
: ardent soy supporters say about the intensive concentration of
: isoflavones in Revival? Clare M. Hasler, Ph.D. University of Illinois at
: Urbana-Champaign's Strat-Soy program, runs the typically very pro-soy
: "Soy and Human Health" answer board and has written about Revival...
: "The company is clearly exploiting all of the interest in the purported
: health benefits of a particular class of compounds in the soybean called
: "isoflavones." My issue with their literature is the statement that, "We
: recommend at least 150 mg of total plant estrogens per day...to ensure
: real health benefits." Read the entire quote at the StratSoy site.
: Regarding Promensil, a recent announcement was made of a study presented
: at the Spring 2000 Endocrine Society meeting, suggesting that the
: over-the-counter dietary supplement called Promensil can help in
: preventing osteoporosis. Promensil, manufactured by Novogen, Ltd., is a
: natural dietary supplement made from plant estrogens (isoflavones)
: extracted from red clover. Some experts, however, believe that the
: concentrated isoflavones in Promensil will negatively impact thyroid
: health in the same way that isoflavones from soy foods and supplements
: can increase the risk of thyroid problems, as well as aggravate
: pre-existing thyroid problems. In Australia, where Novogen is based, the
: company has been under attack for allegedly misleading advertising.
: (See: http://www.soyonlineservice.co.nz/bull.htm ) Interestingly, the
: study presented by the Endocrine Society was itself funded by Novogen,
: the manufacturer of the product studied."
: Hope that gives you some more information on which to base your decision.
: I have noticed that I feel worse even when using packaged food, margines, oils, ect. with soy in it that I feel worse. But perhaps it's just phycological??? Hard to tell for sure.
: Best of luck, Tina ....P.S. if you do try it will you let me know how it goes?
i don't think i will try soy.
