“The research that the WHO has referenced to make their decision is based on high aspartame consumption,” says Melanie Murphy Richter, a registered dietitian nutritionist and instructor of nutrition physiology at the University of California, Irvine. “If consumers are more aware about these potential issues, they can choose to decrease or moderate their aspartame consumption.”
Richter points out that like aspartame, these problematic outcomes are seen when consuming large amounts of the sweetener. She recommends low or moderate consumption of sucralose. Lyons, on the other hand, does not recommend using Sucralose at all as an alternative. “My suspicion is that as more research emerges, Splenda might be implicated in negative health outcomes.”
As with all health decisions, individuals need to make the choice that right for them — and the benefit of lower-calorie products may outweigh the risks for some people. There’s concern that people who may have been using artificial sweeteners to lower sugar intake may turn to foods with high added sugar content, says Richter. “We still live in a society where added sugar is used in so many processed foods,” she explains. “It is one of the main drivers and causes of the top chronic illnesses our population faces — diabetes, heart disease, cancer and obesity, to name a few.
