believe it or not--soy has it's problems too


Quote  |  Reply
I recently (yesterday) went to a MD that is also a naturopath doctor.  I have lost weight (10 lbs since Jan 1) and want to lose more, I'm a chronic yo-yo dieter (weight watchers x 3, nutri-system x 1, e-diets for 3 years), and I always am depressed and fatigued.  Not only did he run a gammet of tests for every vitamin and mineral and hormone in my body, he also talked with me about my diet.  I did tell him that I have IBS (irritable bowel production), so I cut out dairy and eat only soy and soy milk.  He did let me know that soy can decrease your thyroid function--causing hypothyroidism.  Sometimes this does not show up on blood tests, even, however this causes decreased metabolism.  Not good when trying to lose weight.

I am in the health care field (I'm a physical therapist) so I did my own search prior to posting this to ensure that I was passing along scientifically sound info.  I came up with a gazillion web sites that do report that in just one 5 to 8 oz glass of soy milk a day can significantly alter your thyroid production.  Don't even ask about what it does in infants using soy formula--it's scary. 

The alternatives to soy milk if you cannot drink cow's milk is almond, hazelnut, or rice milk.  I started today drinking low fat almond milk with my cereal, and I guess since I'm so used to the funky taste of soy milk that it tasted good. 

I just wanted everyone to be aware that soy=decreased metabolism.  We have enough factors in our every day lives that make it hard to lose weight, so I feel that we don't need to inflict another detriment to losing weight onto ourselves!

One of many web sites regarding this issue:

oops--in error I typed "irritable bowel production" instead of "irritable bowel syndrome" for I.B.S.  ;)
very interesting.  I tried changing to soy milk and did not like it.  I think I like the regular skim milk, that is what I have with my cereal and a glass now and then.  But this is good info to know.  I sort of felt bad for not switching to soy milk, really seemed like the thing to do.  I just could not jump on that bandwagon.  Guess its not so bad that I didn't jump on.
Soy doesn't agree w/ my stomach.  I have also read about estrogen-like qualities, but when I posted about it too many people got mad so I ran away.
poohb - what did you read, I am curious.  No one will shoe you away now.  :)
Ok, I'll look for the link.  It seems that the thought of possible increase in breast cancer being related to soy consumption is very controversial.

Ok, found it!  Here's the article I read.  It's really long but if you look down you'll see separate topics (though they're not bolded or anything, you kinda have to look for them). 
That is a great article and seems very well researched.  I did want to repeat, after reading the article, that the MD I saw did say the the soy found in miso and tempeh are good soy.  I see now that it is because it is soy in it's natural, non-processed form.  Like anything else, if it comes out of the ground, it's okay.  The processing, in which things are cooked and boiled and stripped, changes the chemical composition of amino acids which are what acts like weird chemicals and additives to our bodies.  This includes how wheat is processed and stripped down into "enriched wheat" whcih is really "de-riched wheat". 
NOOO! I LOVE soy milk. I have 2 glasses a day. *sigh* THe almond and rice milk here is so fatty and gross. 
I feel your pain red_herring.
Check out this thread it was informative 
what? soy=decreased metabolism? is that true?
More like Soy = Decreased Metabolism for the one or two percent of the population who have a Thyroid Disorder.
Wow I didn't think anybody on this site believed anything negative about soy.  There are so many negatives it is scary...one site states the same as many others. the following is from http://www.soyonlineservice.co.nz/ Most people remain unaware that soy is known to contain an array of potent chemical toxins. The modern manufacturing processes of high-profit industries make no effort to remove these potent toxins. High levels of phytic acid, trypsin inhibitors, toxic lysinoalanine and highly carcinogenic nitrosamines are all present in soy products.

Phytoestrogens that disrupt endocrine function and are potent antithyroid agents are present in vast quantities in soy, including the potentially devastating isoflavone Genistein. Infants exclusively fed soy-based formula have 13,000 to 22,000 times more estrogen compounds in their blood than babies fed milk-based formula, the estrogenic equivalent of at least five birth control pills per day. Premature development of girls has been linked to the use of soy formula, as has the underdevelopment of males. Infant soy formula has been linked to autoimmune thyroid disease.

Soy is linked to infertility, breast cancer, hypothyroidism, thyroid cancer, and many other disorders.
thats so depressing i love my soy milk on my breakfast!!!

i dont like any other milk so i guess ill have to just hope it doesnt effect me! i've been having it for ages too ahhhhh
try ricedream
i've also heard that more & more people are developing allergies to soy.  maybe connected to the high toxin content?
oh man. I just found a lite soy milk that I figured I could use to flavor my coffee. There are always so many conflicting  voices on so many things. It's enough to make you crazy!
Not to jump on the "anti-soy" bandwagon here, but Soy products can also be migraine triggers, but since some triggers don't show up for 72 hours after ingestion, its hard to tell that's what it was from. I've definitely noticed that I get a major headache a day or so after I eat a lot of Boca meat substitute stuff (mostly the Boca Chili). So that's just another fun thing to look out for when dealing with soy products...
that's weird, because I can site tons of articles saying soy boosts one's metabolism... i.e.

I think the study ACTUALLY showed that soy can interfere with thyroid hormone replacement therapy for those with existing low thyroid...NOT that the soy CAUSES low thyroid.


The way I view conflicting studies is as follows. IF studies start appearing that show something in a negative light, then you start to see other studies that counter that view which then confuse us. The way to view it is that if you have conflicting stuides it should be raising caution flags and red lights and we then need to do our own research and carefully come to a conclusion. On soy there is overwhelming evidence that they way it is being produced, sold, and consumed in most parts of the world it is no longer a healthy product to consume. The old ways of eating and consuming it are in no way related to how it is being marketed in this day and age. It is being weaved into foods that it has no right in being included. We are mostly being used as guinea pigs and we shouldn't accept it.
