'Tis the nature of the beast. Deal with it or fold and leave the table. Plain and simple. I read more than I post as I no longer like answering the same questions ad infinitum. I find the most enjoyment in the people I have met and the periodic mental gymnastics in which we can engage here.
Now 5khours and I may have appeared to be verbally sparring, and that may be an apt description, but at the end of the day he took the high road and earned everyone's respect I think. Certainly mine. And I know for a fact we are miles apart on opinion.

The fact is to ask a group of unknown people on a faceless internet forum a serious question expecting only seriousness and absolute knowledge in response is a bit of a leap of faith.
I would suggest a perusal of the threads here point you, at least with specific respect to food, to other food sites to find the answers to the more specific questions you pose.
