Can I eat NutraSweet® or Splenda® while I am pregnant?

Using artificial sweeteners  helps  reduce your sugar intake and the risk of tooth decay. Most artificial sweeteners can be safely eaten while you are pregnant. The FDA has approved sucralose (Splenda®), aspartame (NutraSweet®), and acesulfame-K for pregnant women. But the FDA has not approved saccharin, which reportedly does not taste as good as the others anyway. Saccharin might be harmful to fetuses because it can linger  in fetal tissues, but more research is needed to determine if it causes any significant harm.
