Just bought a 16 oz container of Great Lakes Gelatin powder but the label states "Heavy Metals: less than 0.005%". This seems like a lot of heavy metal contamination. Other gelatin products are more specific and state "Heavy Metals (as Pb)" so we can likely conclude that the major culprit in Great Lakes brand is also lead (Pb). The label states "LESS THAN 0.005%" so this is the upper limit, but I would imagine the actual % is not too much lower otherwise they could and would advertise a lower contamination %.
Calculations reveal that:
One 7 gram serving provides (less than) 0.35 mg or 350 mcg of heavy metals. The entire 16 oz container provides (less than) 22.7 mg or 22,700 mcg of heavy metals.
So just 1 serving (1 tbsp) will give you "less than" .35 mg of lead. And when you finish off the container you will have ingested "less than" 22.7 mg of lead. This seems like a lot of lead to ingest.
Something off the net to put things in perspective:
"300 mcg (.3 mg) of elemental lead is considered to be the maximum daily permissible intake (DPI) from all sources for children. As the average intake increases above this value, the entire amount cannot be excreted and accumulation in the body begins."
