In exactly what way does it sound like that? Did coffee companies find out that about a asprin's weight of coffee grounds would kill a monkey, and suppress that information? Or is it because just because that you think it's not important that a study found that some aspect of coffee could cause cancer in rats, and you also don't care about studies about PFOAs, so they're the same?
