I have what I think is a better bottom line. When there have been reported cases of people, not rats, dying with as small a dose as 5 mg kg-1; and the WHO, independent international cancer research centers, and the FDA establishing the fact that no matter what, there will always remain some level of potassium bromate in baked goods; and the FDA specifically recording unsafe levels in commercial bread in 1992 and 1998; and understanding that the virtually safe dose (VSD) for potassium bromate with a risk level assigned for genotoxic carcinogens in 1990 is around 1 ppm, and bromated flour has a concentration of up to 75 ppm; and people wear seatbelts even though they don't anticipate being in a vehicular accident, or don't stand near a tall tree during a thunderstorm even though few people are struck by lightning; it is quite reasonable and responsible behavior to frown upon adding a known deadly toxin to edible substances.
On the other hand, to take your position would mean forming an opinion solely on the basis that you don't like the evidence. That shows quite a lot of confidence in your opinion without ever having set up your own clinical trials, or conducting a single medical experiment. The normal reaction for most people is not, "Oh, there is a deadly toxin of unknown proportion in my food (pizza), I think I'll eat it anyway until someone provides evidence that the unknown proportion is at a safe level to eat."
I'll go ahead and pass up the option of denial and stick with a simple understanding that potassium bromate is carcinogenic at levels found in raw bromated flour.
I take a lot of risks in my life, but almost never with my health. In fact, I'm a doctor's worst nightmare because I have never smoked, consumed alcoholic beverages, taken prescription medications, taken non-prescription medications (e.g. aspirin, cough syrup), or engaged in risky physical activities my entire life. I experience absolutely no downtime due to illness (e.g. viral infections, bacterial infections, diseases, disorders), and I haven't seen a doctor regarding any ailment in my entire adult life. Before you conclude it has to do with genetics, both of my parents are obese, I am not; both of my parents wear glasses, I don't; my father started balding at an early age, my hairline hasn't moved since I was born; both of my parents have required surgery for various reasons; I have not. I don't site this anecdote because I think it has anything to do with avoiding bromated flour or because I'm anyone special. I site it to illustrate that the human body is capable of taking care of itself if you don't abuse it, and that most certainly includes consuming known toxins at unknown levels. Of course, you're welcome to disapprove of my "apple", but in my case, it really does keep the doctor away and my life is by no means boring.
I have no interest in discussing this further either.
