I want to learn more about artificial sweeteners and sugar substitutes. Again, the propaganda was that they caused cancer in mice......but they didn't tell you that the amounts that were fed mice and rats were comparable to amounts a human couldn't possibly consume. So the sugar industry conspiracy raises its ugly head again. I am particularly curious about how to use stevia and I'm wondering about any dangers in aspartame as many of the diet drinks I like for mixing beverages with contain this.
