“Cyclamates were banned in 1970. One study a few years after the ban indicated that a person would need to consume around 800 soft drinks PER DAY to get cyclamate-caused cancer.”
Remember that. They were the only diet soda I could stand to drink, and IIRC, the dosage level to cause cancer was like you or I drinking a 55-gallon drum of the stuff a day. I was drinking a case of Coke a day back then, but it wasn’t THAT bad.
