Diet changes for Hashimoto's

Hello I was hoping for some advice on dietary changes I could make to help me with hashimoto's. I have just read Isabelle Wende's book and to tell the truth I found it a bit overwhelming. I was diagnosed with Hahsi's in February my tsh was 12.7 and my TPO was 433 and T4 was 10.36. I was put on 50mg of leveothyrox, which has now been elevated to 62.5mg, my current results show my TSH is 5.4. I have started the 5 2 diet which is helping me to shed the extra few kilos that I have recently put on. But in I have read fasting is not good for hashimoto. Should I not be doing this? I have a question about fluoride. We have no fluoride in our water and our dentist told me to buy salt with fluoride to keep the family's teeth healthy. Wende says that you should not have fluoride and iodine, which is added to the salt I use - should I stop using it? Also I use cold-pressed rapeseed oil for cooking. She mentions rapseed is not good - it that just commercial Rapseed or cold-pressed too? We are a family of four and we eat together as a family. Is there any specific advice for changes I can make to the food we eat. I try and cook heathily - loads of veg and fruit, fish and white meat and low gluten. Thanks for any thoughts or advise.

You are undermedicated on 62.5mcg to have TSH 5.4 and that might even make you gain weight rather than lose it. Many members have said they find the 5:2 diet very good and have successfully lose weight. Some members believe fluoride is damaging and prefer to use fluoride-free toothpaste. Coconut oil is often recommended as an alternative to vegetable oils. Hypothyroid patients should be getting the iodine they need from Levothyroxine and diet.

The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 1.0 or lower with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted. Read Treatment Options in Email if you would like a copy of the Pulse article to show your GP.

Thyroid peroxidase antibodies are positive for autoimmune thyroid disease (Hashimoto's). There is no cure for Hashimoto's which causes 90% of hypothyroidism. Treatment is for the low thyroid levels it causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies.

There is no point in doing low gluten. If you have sensitivity to gluten even a crumb will cause problems so unless you intend being 100% gluten-free you may as well not bother.

Ok thanks. I have suffered with palpitations - I think from the medication, so the endocrinologist is taking it slow with the levothyrox- I have another appointment in July when I think the level will be increased again-I still have massive fatigue, and everything feels hard work at the moment 🙄

I don't seem to have a sensitivity to gluten, I just feel better for not eating bread and pasta.


Hard to tell whether the palpitations are caused by Levothyroxine or by undermedication when TSH is 5.4.

If you were considering a dietary change to improve Hashimoto's you would need to be 100% gluten-free to see whether there is any improvement whether or not you have sensitivity to gluten.

Yes you are right - I don't know if the palpitations are due to the medication or not. Still not feeling great with the dose I am on, so will make sure it gets increased next visit, thanks for replying.

Fluoride does not keep teeth healthy! I would change my dentist, if I were you. That is just a myth. It can, however, affect the thyroid gland, and is best avoided. As is iodine. So, I think you should change your salt! Sea salt, or pink Himalayan salt, would be much better for the whole family, because it's not processed like table salt. There are no additives in natural salt.

I didn't know you could cold-press rapeseed. Rapeseed oil is said to be bad because it is processed oil, meaning that the oil is not easily extracted from the seeds in the way that it is from olives and nuts. It's usually made by extracting the oil from the seeds at high temperature and using solvents and chemicals to bleach, degum and deodorise the product. Which, as you can imagine, isn't very healthy for us. But, I would imagine that, if it really is cold-pressed, then it should be ok. :)
