When i went through the menopause i used soya products for a couple of years and developed hypo. After hearing about soya and how it can cause hypothyroidism i obviously blamed soya.
However many women get hypo going through the menopause due to oestrogen dominance etc. So i suppose you should not just assume.
Hv's arguement is that there is lots of goitrogens in lots of foods, brocoli etc but when cooked it is fine for hypos, and soya is heated in the process to turn to milk or whatever, so why should it be more harmful than anything else.
I've been wanting to take the lecithin for awhile but have been put off by the fact it is from soya. I also tried the milk again recently it was non gmo and unsweetened. I was trying to avoid the lactose in milk, but have found some lactose free milk, so using that now instead.
I was so ante soya for years, getting upset they even sold it in the healthfood stores and supermarkets, because i put the blame entirely on soya for my problem.
I just don't know. I am also not totally convinced it is harmless, but as i really want to try the lecithin i will give it another go.
