It is not theory that sucralose kills candida. It's a fact. Why would the makers of Splenda change their policy of selling pure sucralose? Why add nutrative sweetner to a perfectly good product when certain people will be harmed by this action? All you have to do is some detective work as I did to understand why certain actions were carried out. Compare the reported, so called toxic effects of Splenda to the die off symptoms of candida yeast. They are the same. The FDA's report on the effects of sucralose on the human body list a chance of microflora of the gut. They stopped short of admitting a die off of yeast in the gut.
