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

[–] IronicDeadPan@lemmy.world 13 points 10 months ago (1 children)

that's Greek letter mu. It means micrograms or one millionth of a gram

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,

Because of the high capacity of cocoa bean shells to adsorb lead, contamination from leaded gasoline emissions may occur during the fermentation and sun-drying of unshelled beans at cocoa farms. ... However, the much higher lead concentrations and larger variability in lead isotopic composition of finished cocoa products, which falls within the global range of industrial lead aerosols, indicate that most contamination occurs during shipping and/or processing of the cocoa beans and the manufacture of cocoa and chocolate products. source

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,

One source of contamination of the finished products is tentatively attributed to atmospheric emissions of leaded gasoline, which is still being used in Nigeria. Because of the high capacity of cocoa bean shells to adsorb lead, contamination from leaded gasoline emissions may occur during the fermentation and sun-drying of unshelled beans at cocoa farms. Source (same as before)

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.

Whoa, that site is awesome! I switch between Ghirardelli's and Lindt's super dark bar varieties. Looks like I need to stick with Ghirardelli.
