I found out the cause of my brain fog. No, it wasn't my hypothyroid, nor my anemia. And ACV seems to have been totally innocent. IT WAS CANOLA OIL.
I have been very sensitive to not-so-good quality of oil from my childhood. As we couldn't find the regular vegetable oil I use at the supermarket around beginning of April, I bought Canola oil. As the container was leaking, I transferred it to the vegetable oil container I had at home which was empty and forgot all about canola oil. Shortly after I had started using it, I had trouble with my memory and concentration, but I had forgotten all about my sensitivity to oils and about canola oil as it was coming out from the vegetable oil container. Just 5 days ago I remembered my sensitivity and researched about canola oil on the internet and found others who have had similar problems. It was also mentioned that it effects the central nervous system and could cause blindness in the long run. I stopped using it right away and started feeling better the next day itself.
I am glad I am sensitive to not-so-good oils as I feel the effects immediately. My family members who are not sensitive, would have seen worse effects after a few years if we continued to use it.
While I was reading about oils, I also found that the vegetable oil (the container of which has pictures of vegetables on the front) is actually a soy bean oil. I never read the ingredients as the name says vegetable oil and it has has pictures of vegetables. I found that soy bean oil is not at all good for thyroid and generally.
I have been using olive oil for normal cooking and vegetable oil for deep frying (sometimes) since. But since the vegetable oil isn't good and olive oil is not suitable for deep frying - it leaves the question...which is the best oil to use?
I would appreciate input from others as to which oil to use - which will not be hard on thyroid and which will also not cause brain fog or any other health issues.
