While 'giving the public what it wants' is the basic policy of all exhibitors, one must be judicious in offering anything that is not a standard, time-proven food. The suggestion to offer anything with SPLENDA or any other artificial sweetner is a calculated risk, especially if no standard sugar-based products are also offered. It would be nice if every new "scientific" product to come down the pike were the panacea we hope it to be, but, alas, that is NOT the case! Go to
www.Google.com and type in the word 'splenda' and you will get many warning sites on its first page which will tell of its dangers -- many very little known. Unfortunately, you cannot depend upon the government to clear any product of dangers, nor to back you up in the event some idiot decides to sue you for millions in health care costs ever since the time years ago that they bought some artificially-sweetened product at your place; if it is 'proved' that a health-related problem exists with some product you offered, the government will hide from helping you, and the lawyers will smell a new cause celeb to fatten their check books at the expense of exhibitors too small to effectively fight them!
It may seem obvious that adults should be able to select what is best for themselves and then live with the consequences, but in our litigious society there is always someone who is looking for supposedly "deep pockets" to sue to get money. McDonalds reportedly spent some 5 million dollars defending itself in the famous 'coffee spill' case, so even if you are determined by a court not to be blameworthy in anyone's ill health from your selling a sugar substitute, the costs of defending yourself can easily bankrupt you -- even if you do 'win'! Offer whatever you like, but be aware that there are some 'activists' out there who will relish doing legal ill to you if you buck them. It's a tricky and nasty world out there; be careful! (though I must admit that I wonder when someone will decide that the popcorn flavorings are carcinogenic, and it will be a legal free-for-all.)
