More than 30,000,000 people in the US and 200 million worldwide have a Thyroid Disorder Most affected are women. Some estimates are over 50 million in US and over 200 million worldwide, and growing.

Estimates vary widely as most patients are misdiagnosed or undiagnosed because doctors don't know what they are looking for.

Thyroid disease is also an autoimmune disease. This means that over 27 million people have one or more of the over 105 known autoimmune diseases.

Thyroid Diet: Soybean Oil – One of the Most Harmful Ingredients


I’ve written before about staying away from soy products due to soy being one of the highest

GMO’d foods as well as adding hormones to our system that we don’t need. But, if you’re still

eating processed foods (which you shouldn’t be!) you need to know that soy oil is one of the

top two most damaging aspects of most people’s diet, contributing to poor health and chronic


…..#1 is high fructose corn syrup (HFCS), the dangers of which are monumental.

…..#2 is partially hydrogenated soybean oil.


“These two ingredients, either alone or in combination, can be found in virtually

all processed foods and one can make a compelling argument that the reliance

on these two foods is a primary contributing factor for most of the

degenerative diseases attacking Americans today.”

~ Dr. Mercola



In the soy oil it’s the trans fat it contains, plus the GMO factor. A big double whammy

that’s killing us.



Americans consume more than 28 billion pounds of edible oils annually, and soybean oil

accounts for about 65 percent of it. About half of it is hydrogenated, as soybean oil is too

unstable otherwise to be used in food manufacturing. One of the primary reasons for

hydrogenating oil is to prolong its shelf life.  Raw butter, for example, is likely to go rancid

far quicker than margarine. Raw butter is the better choice by far!



So, why not organic soybean oil? One word: Goitrogens.

Goitrogens, found in all unfermented soy whether it’s organic or not, are substances that

block the synthesis of thyroid hormones and interfere with iodine metabolism, thereby

interfering with your thyroid function.


Bottom line, don’t eat processed foods or soy oil. Read more of this article from Dr. Mercola here.

    Hi Kim, I have been hypo thyroid for 11 years with a goiter. Its larger on the right side and I am just lately having a lot of weird sensations in my throat area to the point where it is driving me crazy. My doctor said its larger on the right side and she acted like it was really large but then my ENT said it wasn’t that big. I also have been having problems on the right side of my head with eye, ear and nostril. Have you ever heard of a goiter pressing on an artery and causing problems? Please help!

    • kim

      Dear Liz,

      I’ve not heard of a goiter pressing on an artery and causing problems, but if it’s big enough, I suppose it’s possible.

      If you’re conflicted by 2 conflicting doctors, please get a 3rd opinion ASAP! This is nothing to be taken lightly.

      Plus, if your doc’s are not “thyroid trained practitioner” you really may not be getting the right answers, not only with the size of your goiter, but all else that it’s affecting in your body.

      Go to my PRACTITIONERS list here http://thyroidu.com/practitioners/ and search the lists for someone in your area who is specifically thyroid trained.

    when i was working at food chain my medical told me that i had a enlarge tyroid.what is enlarged tyroid?but it wasnt seen in my neck and after 15 yaers i havent seen to a doctor for check up what wil i do?

    • kim

      Hi Alma,
      An enlarged thyroid means that your thyroid gland is enlarged on one or both sides of your throat. It would be wise to get checked by a thyroid trained practitioner who can help you long term with any problem you might have and healing your thyroid for your future. If you do have a thyroid problem, it will definitely affect your life in the worst of ways.

      Go to my PRACTITIONERS page at http://thyroidu.com/practitioners/ – find a thyroid trained practitioner from these lists.

    Is the ‘ban’ on soybean products including soya products for vegetarians? (veggie burgers etc)? I have been hypothyroid for 15 years and my diet the last 10 has been mostly soy burgers and other soy products for protein/meat substitution.

    • kim

      2 answers, Tash,

      1. How do you feel? If you are feeling well and have few symptoms, don’t fix what isn’t broken!

      2. All soy has it’s problems in our bodies.
      a) If you eat soy, it must be organic in order not to have GMOd soy, the #1 GMO’d food.
      b) American women have problems with soy as our bodies are not used to and it can mess with our hormones.

      Of course, as a vegetarian, you do need to find many other ways to get your protein too, not just soy.

    Hey Kim,
    I’m 23 yrs old, I was diagnosed with hypothyroidism(my level was 90.5) 6 months. I’m confused n scared. I need help

  • i have thyroid ones it normal and ones high doctors dont give me any tablets i start to louse my hair is
    this from thyroid???

    • kim

      Hi Dianne,

      Yes, hair loss is associated with a thyroid condition.

      You need to find a “thyroid trained” practitioner. Any “regular” doctor/GP or even specialist won’t have been trained or understand the depths of this condition, what tests to run, how to read them and the supplements you need to rebuild your body and brain health.

      You can take any lab tests you have now and get them to a practitioner who can help you immediately by reading them differently and correctly. Find a new one close to you at my site page: http://thyroidu.com/practitioners/

      If you can’t find one close to you, use one of those on the list by phone #. You can email or fax your test results to them and/or they can tell you which tests to have done and get the results back to them. Many will work with you by phone/Skype.

      My thoughts are with you for good health soon,


  • Hi, I have been a diagnosed hypothyroid patient for about 2.years I’m struggling with weight issues so I bought total lean meal replacement protein from GNC not long ago but it contains hydrogenated soybean oil. Should I stop drinking it ?

    • kim

      Hi Cynthia,

      1. hydrogenated soybean oil may not be the only thing in this product that is not healthy for you right now. Soy is best to stay away from all the time due to GMOs and it’s affecting our hormones.

      I’d switch to a better health oriented brand for once in a while supplement and/or meal replacement. Check with your thyroid trained practitioner as they usually have options and can also test them against your body’s acceptance of them.

      You can get your hypothyroidism settled down more quickly with the help of the following:

      1. Eat the THYROID HEALING DIET, a clean diet to rebuild your body/brain health. Don’t depend on powdered protein meals/drinks to rebuild your brain and body health. You can start on this diet immediately by ordering my Get Your Life Back Manual. Included are numerous checklist forms to keep track of your symptoms, supplements, etc. to help your thyroid trained practitioner help you better. http://thyroidu.com/bookstoreresources/my-thyroid-health-plan-manual/

      2. And, see a THYROID TRAINED PRACTITIONER who can give you the correct tests and prescribe the right supplements which they’ll recommend that will be the best for you.
      You can find one near you here – http://thyroidu.com/practitioners/

      If you can’t find one near you off the INTERNATIONAL lists, please contact mine – Dr. Allomong, who is thyroid trained, #1 on the list. He can work with you by phone/email/Skype and help you correctly immediately.

      My good thoughts to you for your best health,


  • kim

    I’m confused about why you stopped taking your medication. The symptoms are not directly related to the meds – either way. It is a small answers to a big problem.

    It’s important to eat the right foods for your condition, staying away from raw goitrogens. Microwaving is not the best answer as it changes food and how it works in the body. You can cook or steam them.

    3) You can get my Thyroid Health Rebuilding “Reset” Diet and eat the best way for your condition right away.

    DIET: The diet is in my manual, see more here: http://thyroidu.com/bookstoreresources/my-thyroid-health-plan-manual/

    My good thoughts for your best health are with you,


  • kim

    Hi Peggy,

    I’m not sure why you stopped taking thyroid meds. Your symptoms will not be helped by not taking a hormone replacement.

    Is it not visable to eat a big bowl of raw salad with spinach, kale, arugula = goitrogens every day.
    If you do eat them you must cook, bake or steam them first.

    I do not support use of the microwave due to research showing it changes the molecules in food that affect our health.

    I’d also suggest that you find a thyroid trained practitioner – go to my PRACTITIONERS tab on this site http://thyroidu.com/practitioners/ and find one close to you on the lists.

    If you can’t find one close, contact #1 on the list, Dr. Jared Allomong, who is my practitioner. He can work w/ you by phone/email easily. He can start to work of your current lab tests to read them correctly for your condition and move directly into your thyroid health needs.

    And, you also need to eat a Thyroid Health Rebuilding “Reset” Diet. The diet is in my manual, see more here: http://thyroidu.com/bookstoreresources/my-thyroid-health-plan-manual/ You can buy it and refine your diet immediately.

    My good thoughts for your best health are with you,


  • Kim

    I have hosshimottos disease. Is it okay to apply essential oils onto my skin if they contain soy oil?

    • kim

      Best to stay away from soy based anything.

      If you are on the right diet and right supplements your Hashimoto’s should only last about 6 months.

      If you still have it I highly suggest you contact my thyroid practitioner, Dr. Jared Allomong – he can work with you by phone/Skype/Email from a distance most times.
      Go here and call or make an appointment: http://functionalhealthcolorado.com/

      My good thoughts for your best health always, Kim

  • Jay LaPrell

    I am on a low iodine diet in the process of a rad iodine scan and follow the recipes given to a tee however I am a bit confused with the part that says no soy sauce {sodium iodine?} or soy beans but soy oil is OK.I use some salt (no iodine).I found potato chips with NO salt but are cooked in a variety of oils, one being soybean oil. Is it acceptable?

  • Deepika

    Hi Kim,

    I wanted to make my hair healthy and I have borderline thyroid. If I take biotin from Nature Made Skin, Hair and Nails, which seems to contain Soy Bean Oil – is that harmful for me?

  • Mary Chi

    To support Kim’s original article – I think I just discovered that besides the normal bad foods (cola, chocolate, pineapple, tea, tomato sauce, etc.), that I have a reaction to soybean oil – just in the last week I had problems with 1) brand name crackers, 2) certain salad dressings, 3) my most favorite brand name crumb cake at the end of the grocery store aisles, and 4) vitamin D3… all are made with SOYBEAN OIL! I can’t believe it – something I never heard of before. I am going to start reading a lot more labels.

    I hope this solves my problem and helps SOMEONE out there. STAY AWAY FROM SOYBEAN OIL AND SUGAR!
