Please don't worry about what you are eating! My metallosis was caused by faulty (since discontinued) metal-on-metal hip implants. Once upon a time, the medical research community got an idea for a hip replacement that would last a lifetime. Instead of using a ceramic ball on the femur, and a polymer lining in the acetabular cup (hip joint) they tried using chromium for one, and cobalt for the other, with a titanium stem. The theory was that the fluid in the joint would lubricate it and with metal, there would be no wear. Oops! Up to half of the recipients experienced metal-on-metal wear. Nearly microscopic bits of the metal deposited in the surrounding tissue, leading to metal poisoning and tissue breakdown. That happened to me, causing metal poisoning which led to pain, tissue breakdown, crazy hyperthyroid, tremors, rapid heartbeat and a host of other unpleasant symptoms. After 5 years, the implants were removed and replaced with traditional materials. It took about 2 more years for the metals to work their way through my system & out of the body, as there is no chelation therapy for chromium or cobalt. Some of my symptoms cleared, others will be my companions for life. At first, the Graves was discounted as an aftereffect of the heavy metal, but after more than a few reports, it has now been added to the list.
About 2 years later, I regained most of the hair on my head and my eyelashes, but little of the hair on my body. I used to have bushy eyebrows I needed to tame, now they are scant & must be filled in with makeup.

When this happened, I learned that in medicine, new is not necessarily better. I ask FAR MORE questions now, and do a lot of research on my own.
