Yes, you got a point there AWC. There has yet been any known person that has actually put the theory to the test but considering the seriousness of DF abilities and how it could potentially make or break you in the OP universe, I'm sure that the credibility of the statement "eat more than 1 DF and you will die" is to be taken seriously and for granted.

Otherwise, we'd have tons of random Tom, Dick or Harry being force fed with more than 1 DF, especially in the case of the Tenryubito sadistic nature - the joys of seeing their slaves die a painful death by consuming two DF just to 1) test the theory 2) to their amusement. They certainly has the money to buy the DF and the headcount of slaves at their disposal to do it.
