Q: I use a lot of aspartame (Nutrisweet), but recently read that a new study shows it might cause leukemia, lymphoma and breast cancer in rats. What is best to use instead? –Sam, TX
A: One of the best natural sweeteners is made from the herb stevia. It has zero calories, zero carbohydrates, and is a zero on the glycemic index. One brand, SweetLeaf, offers stevia in flavored liquids (for example, stevia and cinnamon or orange), as well as in little packets similar to synthetic sweeteners.
