The process of brewing coffee removes heavy metals. Is there a way to prepare cacao/cocoa/chocolate to do the same?

I have always found the profile of cacao especially impressive; however the presence of lead and cadmium* makes me wonder if there's an ideal way to prepare and consume the stuff which would minimize that.

 

(*which coffee doesn't have too much of in the first place, and not only the coffee filter but coffee grounds themselves appear to act as a filter which reduces them in a brew) https://www.nytimes....tals-water.html

 

One thing I have been doing is adding a bit of a cacao extract (which has some lead and cadmium as almost all cacao seems to, though not much) to my coffee grounds. I use pour-over preparation with paper filters. because the extract is finely ground and I believe retains the high fat content of chocolate to an extent, this slows down brewing but intuitively I think it might be helpful in the same fashion as seen with coffee.

Cacao is of course full of catechins, so theoretically that's promising for sure.

 

And now I'm imagining garlic hot chocolate ... mmm ...

well you could take a garlic supplement every time you eat chocolate. Garlic supplements are pretty awesome anyway for lots of reasons. EGCG also good source of cetechins

 

Chcocolate bar plus garlic pill plus EGCG, sounds delicious and healthy

Why are garlic supplements useful?  Doesn't the allicin only last for a half hour after you cut beside?
