I have had the wild blueberry so far and they are EXCELLENT!!!

Here is what the the Center for Science in the public interest says about Acesulfame-K… Avoid itl. The testing that was done to get it approved as an additive in the ’70s was not inadequate… and once something is approved they don’t really look at it again. I don’t care what adults decide to do, but try to keep it out of your kids’ diet……

This is form their website-http://www.cspinet.org/reports/chemcuisine.htm
ACESULFAME-K
Artificial sweetener: Baked goods, chewing gum, gelatin desserts, diet soda, Sunette.

This artificial sweetener, manufactured by Hoechst, a giant German chemical company, is widely used around the world. It is about 200 times sweeter than sugar. In the United States, for several years acesulfame-K (the K is the chemical symbol for potassium) was permitted only in such foods as sugar-free baked goods, chewing gum, and gelatin desserts. In July 1998, the FDA allowed this chemical to be used in soft drinks, thereby greatly increasing consumer exposure. It is often used together with sucralose (see SUCRALOSE).

The safety tests of acesulfame-K were conducted in the 1970s and were of mediocre quality. Key rat tests were afflicted by disease in the animal colonies; a mouse study was several months too brief and did not expose animals during gestation. Two rat studies suggest that the additive might cause cancer. It was for those reasons that in 1996 the Center for Science in the Public Interest urged the FDA to require better testing before permitting acesulfame-K in soft drinks. In addition, large doses of acetoacetamide, a breakdown product, have been shown to affect the thyroid in rats, rabbits, and dogs. Hopefully, the small amounts in food are not harmful.
