      Regardless, I suspect that as you say even with a massive factor the effect would still only be seen in people drinking liters of coffee a day which is probably not a big slice of the population

      Looked it up! The standard FDA scaling factor from rats:humans appears to be 62, so I should divide my 250,000 by 62 which is 4,000 or 4 liters of coffee a day. Not as fun a number but still pretty bigpic.twitter.com/HeEP0dSmpb

      California's math for acrylamide starts on page 38 here: https://oehha.ca.gov/media/downloads/crnr/acrylamidensrl.pdf …

      They arrived at a level of 0.1 microgram for a 70-kg human as the daily dose. By your calculations it sounds like a cup of coffee has 0.3 micrograms, so the image of drinking buckets of coffee doesn't apply with those numbers.

      Hmmmm that is pretty interesting. They are using some extremely conservative extrapolations there, but you're right I guess I can see where they're coming from

      Just noticed something odd: in the analysis they note that the average daily intake of acrylomide is 30 micrograms/day which would seem to make their NSRL problematic!

      Not necessarily, if they're arguing we all get too much. Remember, they use a very very small threshold

      Mmmm but if the average daily intake is 300x the NRSL then what's the point in labelling anything?

      A bunch of potato chip makers started using a less (no?) acrylamide process so that they wouldn't have to print the warning. That's basically how the law is supposed to work.

      But...olives have high(er) levels of acrylamide. So does toast. Baked potatoes. Pretty much anything where you're burning starch. I think the major dietary sources are very common foods rather than discretionary items
