You won't know unless you do it. If you wait for a diagnosis, you may never get one because testing can often miss problems like this.

The things that will mess you up are sugar, gluten, (or in fact any grains at all), yeast etc. It could be candida that you have, as mercury usually allows overgrowth to occur and then you end up with a whole lot of problems, which yu might attribute all to mercury and often it isn't always. Candida and mercury can also cause gluten intolerance OR gluten intolerance can attribute to these conditions. I think it can go either way.

Problem is, many people are addicted to the very foods that feed the problem, so they do not want to give them up. therefore they just keep struggling with the same issues.

If I can do it anybody can. Giving those foods up was awful for me in the beginning, i was actually crying because of the cravings. But I kept going and finally saw results. Sometimes you have no choice if you want to see improvements. Also, when you are sick with candida/gluten intolerance, you can end up either overweight or underweight. This is because you are actually being starved of nutrients, so you constantly feel like eating or you may even lose your appetite completely. It's odd, but it seems it can go either way. It's just a form of being ill. I have had it both ways. I've been overweight and underweight, but the problem was usually the same.

The only way to know if the diet is causing issue is to actually do it. It's not as though it's going to hurt a person, it is very healthy to give those things up, even for a person in normal health. So the only side effect is temporary pain from the withdrawal. Some people may improve right away, others get worse temporarily.

So, I'd say you'd do well getting off these things regardless. Also, I heard that grain is often treated with mercury in fungicide...so not sure, but perhaps this could be part of the issue.
