Can you really n your own mind think you can get mercury poisoning from eating tuna fish? I didn't say that mercury or heavy metals can't cause ALS. I said Tuna Fish doesn't cause it.
How do you know that? I'm shaking right now trying to decide how you can say in one sentence that you can't get mercury from tuna, and in the next that mercury or heavy metal may cause ALS. A better response to someone who asks is "...if you have any doubts, why take a chance?"
I have eaten lots of fish (tuna included) in the past 52 years and as far as I know, I suffer from no known neuro-muscular disease. But my petite wife, Lisa, has eaten little BUT tuna for most of her adult life. (How do you think she maintains that slender figure!) In addition, she has worked in dentist offices for the last 30 years where amalgams fillings have been used. She has one silver filling and seven root canals. I can go on and on through a long list of factors we have discovered in the last few weeks that may have added to the toxicity levels in her body. My point is, the mercury from tuna or amalgams or wherever it comes from may not be a problem for 99.9% of us, but I think it is very possible that it may, just possibly, be a problem for that 1/10th of 1 percent who are prone to neuro-muscular disease.
Silver fillings contain mercury, and even though dentists and the ADA will tell you that the mercury is "safe" because it is encapsulated, I find it much more likely, that as the silver that surrounds that mercury degrades over the years, a little of it may end up affecting your brain and nervous system. It probably doesn't take much. So if someone asks me if the tuna they're eating can cause ALS, I'd probably tell them the chances are slim as well. But I'll also mention that the metal in their bodies probably can. That's much more responsible, IMO than just shrugging it off.
Dentists and the American Dental Association have a huge stake in telling you that amalgam fillings are safe. If they ever admitted that they weren't they would all be out of business. It's an incredible Catch-22 for dentistry. I'm sure most dentists (and I know several from the years that my wife worked with them) are not evil. They don't want to kill their patients. But think about it. What a dilemma they face. On the one hand, their patients are screwed (or at least a very small percentage of them) if they use amalgams. And so they play the odds and continue to use them. But the minute a dentist stops using amalgams, they're admitting that they might not be safe, and that means THEY are screwed. Since it's safe to say that practically every adult in the US has at least one silver filling, think of the lawsuits it would open them up to. No, they will never admit its harmful. But that doesn't necessarily make it true.
Dentists who remove amalgam fillings because they feel they are unsafe can have their licenses pulled and be barred from ever practicing dentistry in the US by the ADA. They're not even allowed to talk about it. That's kind of scary.
