the International Dairy Foods Association (IDFA) and the National Milk Producers Federation (NMPF) have filed a petition with the FDA asking the FDA to alter the definition of "milk" to secretly include chemical sweeteners such as aspartame and sucralose.
Importantly, none of these additives need to be listed on the label. They will simply be swept under the definition of "milk," so that when a company lists "milk" on the label, it automatically includes aspartame or sucralose. And if you're trying to avoid aspartame, you'll have no way of doing so because it won't be listed on the label.
This isn't only for milk, either: It's also for yogurt, cream, sour cream, eggnog, whipping cream and a total of 17 products, all of which are listed in the petition at FDA.gov.
