is 0.768 ppm lead for ceylon cinnamon too high?

@sneedful looks best to avoid cinnamon, potent anti thyroid

p is cinnamon, few grams and they couldnt even detect thyroid hormone anymore

@LucH -"For example, cells in your arteries require zinc. If zinc is not available, the body will substitute toxic cadmium for this metal. The result is arteries that are less flexible, leading to high blood pressure and damaged or cracked arterial walls. The body then tries to repair the damaged arteries by patching the cracks with plaque (=> cholesterol)."

This is new info to me. How much Zinc/how often for a person who won't eat oysters? I think I remember this is a mineral you don't want to overdo.

If you eat meat once a day, you won't lack zinc.
10-15 mg zinc is adequate.
We must pay attention to balance with Cu (copper): 1.5 mg.
When there is suspicion of infection or flu, I take 30 mg zinc and upgrade Vit D3 from 5 000 UI to 10 000 UI for 2 days. Mind K2 if high level D3 (> 2 000 UI).
I never take Zn or Cu at the same time than I eat dairies (if < 40 mg Ca). Same transporter.

FYI, they gave the rats an anti-thyroid drug!

Here we investigated the effects of chronic ingestion of cinnamon on lipid metabolism of hypothyroid male Wistar rats. Rats received methimazole for 7 weeks, and treated either with cinnamon

Methimazole is an antithyroid medication used to treat hyperthyroidism and is categorized within the thioamide drug class. Methimazole primarily functions by inhibiting thyroid hormone production in the thyroid gland

@wrl aye , 3rd group is hypothyroid + cinnamon. which took the lower thyroid levels to undetectable amounts

here extract severely lowered t3 action in the heart https://pubmed.ncbi.nlm.nih.gov/26374392/ and that other one shows regular powder does it too, i dont think its safe , at least at gram amounts as regular powder, idk how much less is needed to not get that effect

@sneedful t3 aside on lead obviously taking in more is not great but ~~0.000768% if its 500mg is in nanogram amounts so not very significant compared to what you'd find in most peoples blood (microgram / L)~~ actually thats just pushing into microgram amounts, its hard to tell whats significant but might be pushing it over time depends on absorption. if you go >3.6ug/dl its probably (association) significantly more toxic than <2ug. so 1.6ug/dl could be enough to make a difference. but as thats higher shared across 5L blood that seems like its a 80ug difference to me

idk though, for some reason theres consensus on every +1ug of intake being +0.16ug/dL, so +10ug would make the difference. maybe it doesnt eliminate well & builds

https://www.edf.org/sites/default/files/edf_lead_food_report_final.pdf "EDF used a ratio of 1 µg/day of dietary lead intake to 0.16 µg/dL of blood lead level (BLL) to estimate that 2.9 µg/day of dietary lead intake would result in a BLL of 0.46 µg/dL"

In NHANES III (1988–1994), patients with the highest tertile of blood lead (≥3.62 µg/dL) compared with the lowest tertile (<1.94 µg/dL) experienced a significantly higher risk of death during followup. The increased risk was 25% for total mortality, 55% for cardiovascular mortality, 89% for myocardial infarction, and 151% for stroke

0.768 ppm is 0.768mcg/g which is high because 2mcg is max for children set by fda apparently and if fda says <2mcg is "safe" I bet it's way lower threshold

@LucH Good information. Thank you.

they powder it themselves in USA and i doubt they are using a machine with lead so it is probably naturally occuring lead from Sri Lanka

This is a good question and timely for me. I've been attempting to get spices and herbs with as little contamination as possible, and I'm finding that this is not easy to do, especially for Ceylon cinnamon. If what I'm finding is correct, Ceylon, of all cinnamon, is currently not even available without contamination:

I realize you have to take these reports with a grain of salt, as there can be contributing factors that don't allow for the whole picture or even an accurate picture.

@Mossy , between that site abd this one, you wonder if ANY prepared food is safe. The best thing on these charts is plain chocolate m&m.

@Mossy yeah it is too contaminated . ill look for a farm with better soil

Yes, it does shine a light on the high contamination of manufactured foods. That site I referenced does attempt to offer up a "best" option, with limited to no contamination; though, depending on the food, there can still be contaminants, and in some cases, like the Ceylon cinnamon, the contaminants are so high that they can't even recommend a brand.

If the cinnamon here refers to the bark, I doubt the lead would be coming from the bark itself. As before lead could get into the bark, it would be filtered off my the xylem of the true and the lead would stay in the center of the tree trunk. The bark is the farthest from the center of the tree, where the xylem is, so it should be free from lead or whatever contamination.

If ever there is lead contamination, it should be coming from the processing of the cinnamon bark after it has been harvested from the tree.

Thank you, Yerrag. I believe the testers are testing the end product of ground cinnamon. Under the "Better" and "Best" categories, they do not note any brand of Ceylon cinnamon. This is what they note under their "Not Our Favorite Cinnamon" category:

"These products were found to have detectable glyphosate according to our EPA-certified laboratory OR they have over 1,000 ug/kg of lead. Some of these products also could require Prop. 65 warnings based on 1 gram of cinnamon per day. (ug/kg = ppb) As an explainer, California Prop. 65 would require a warning accounting for 1 gram of cinnamon per day above 500 ppb lead and 4,100 ppb cadmium or more."

For now, I'm not going to go with any Ceylon cinnamon, and instead go with the one under "Best", that is supposedly less contaminated:

365 Whole Foods Market Organic Cinnamon Ground — Non-detect glyphosate, 14.87 ug/kg lead, & 93.75 ug/kg cadmium

I have the mountain rose organic ceylon. I read that the contamination is coming from the soil in Sri Lanka. @yerrag I wouldn't think that lead would make it to the inner bark either, but these sticks tested high too https://tamararubin.com/2024/10/simply-organic-cinnamon-sticks/ They can't be getting that much lead contamination just in peeling the inner bark and chopping it could they?

If lead is so wide spread in Sri Lanka soil, I wonder about coconut products from there.

I also have the mountain rose organic cassia cinnamon, from Indonesia. Has anyone seen any tests on cassia? I know some people avoid it because of the coumarin, but I'm not worried about it in the quantities I use.

@Sippy the cassia is 0.06ppm

@sneedful thanks. Did you just request a COA from them?

@Sippy yeah

@Sippy @Mossy thanks.
