I remember the “Cyclamates (sugar substitute in sodas) causes cancer!” hysteria some years back. It was “proven” when tested on rats.
Cooler heads pointed out that the rats in question were fed the equivalent of a human drinking a 50-gallon drums worth of soda each day. No matter, damage was done, cyclamates were recalled, and the world was saved.
Others pointed out that the rats used were the Fischer 344 type rats (???), which got cancer even when injected with water.
Hmmm, I’m going to do my own experiment. Since no ‘rats are allowed in my house, I’ll place my mouse in a glass of coke and see if it’s dead in the morning. Call me in 3 days for the result.
