Makers of the other sweeteners fear stevia for good reason. It’s not only sweeter than the competition — it’s safer. Aspartame may cause headaches, dizziness and nausea. The FDA tried to ban saccharin in 1978 because it was linked to cancer in lab animals. Congress stopped the ban, but products containing saccharin were required to carry warning labels. Some studies show that Sunette causes cancer in lab animals. Meanwhile, in more than a dozen studies over the past decade, stevia has never been shown to cause any adverse effects.
