Here are last year's testing results, in a table with filters:
https://www.asyousow.org/environmental-health/toxic-enforcement/toxic-chocolate#chocolate-tables
If you sort by highest lead content you get "NOW Healthy Foods Certified Organic Cocoa Powder 100% Pure" as the top result, and highest cadmium content you get "Sunfood Super Foods Raw Cacao Powder- Certified Organic" at the top. I find it hilariously ironic that the two highest ones are "Certified Organic". Also, the highest lead one was "100% pure".
What does the "ug" stand for in that table. It isn't actually a "u" but it kind of looks like a u
that's Greek letter mu. It means micrograms or one millionth of a gram
Thank you
Micrograms
Thank you
I love lemmy, if nothing else because you can ask serious questions about something you don't know and not get, "Google it n00b" as the response!
That's because cacao containing cadmium/~~lead~~ is an "organic"(ish) problem. ~~The cacao tree pulls it from the soil.~~
Edited (See below for correction)
That's interesting, I didn't know that before, so I did a bit of research on this, and while you are right that Cacao seeds do absorb some lead naturally when growing, a couple studies have shown that most of the lead that ends up in cacao likely comes from after the farming stage,
So most lead contamination came from processing the chocolate rather than from the tree absorbing it. Also, the same article says that the lead is likely from gasoline vapors, not from the soil,
I haven't read the whole article, but I think this is good enough to serve as a counter-argument. Also, I know the article says "cocoa" instead of "cacao", but it seems "cocoa" is basically just processed "cacao", according to this article on healthline. So basically, the use of cacao and cocoa is inconsistent and may just refer to cocoa beans and/or processed cocoa beans.
Also, I found this article, which seems like the abstract to this source, but I can't figure out if it really is or not. If anyone has any idea of the relationship between the two articles I'd be happy to hear it.
That's some pretty solid research! Thanks for taking the time to look into it and correct me. I didn't realize leaded gasoline was still widely used. It will likely continue to poison the soil as well.
It does appear there is some bioaccumulation of cadmium (PDF) though/contamination from the soil during processing as CyberDine pointed out.
Lead would be considered organic to the extent that it's not added to the product. Hell arsnic is organic.
If by that you mean that the lead was naturally added when it was growing and not during any processing stages, then see https://lemmy.world/comment/4831887. According to an article I found, most of the lead seems to be coming from the the cocoa being processed, not from when it was first grown. Although, it IS only one article, so I may be wrong.
Thanks.
