22 Jul 2019 --- The world’s “most widely used” artificial sweetener has not been adequately proven to be safe for human consumption, argues a newly published paper from University of Sussex researchers. The team detailed serious flaws in the reassurance provided in 2013 by the European Food Safety Authority (EFSA) about the safety of aspartame – more commonly known as Nutrasweet. The researchers warn that the food industry needs to progressively diminish the sweetness of its products, rather than shifting to sweeteners.
