A federal jury begins deliberating today in a false-advertising case that could transform the market for sugar substitutes. It’s the Equal vs. Splenda case, or, as it’s known in court papers, Merisant Co. v. McNeil Nutritionals.

If Equal gets its way, Splenda will be forced to abandon its slogan that says the product is “made from sugar so it tastes like sugar” and could be hit with a verdict of more than $200 million.
