I have suffered from symptoms which I have just recently linked to possible Mercury poisoning such as concentration problems, metal taste in mouth etc but want to know why, if there are millions of people with loads of fillings in, are quite happy and healthy. The reason i think why some people suffer and not others is because of your diet. I have only just started eating quite healthy in the last couple of years( plenty of salads, fruit + veg) Since then i have noticed more symptoms such as brain fog, constant metallic taste intollerances to food, feeling depressed after eating sugar etc. What i think must be happening is that if you eat healthy your body must dump more mercury into your system so you start suffering more. But if you eat loads of fats and poor food then most of the mercury gets stored in fat instead of in your organs. toxins that are stored in fat will be safe temporary until broken down through exercise or diet e.t.c This could be why alot of people can tollerate it. What do think about this.
