Question: are stevia and erythritol safe?
Answer: The best and safest sugar substitutes are erythritol, xylitol, stevia leaf extracts, and neotame—with some caveats: Erythritol: Large amounts (more than about 40 or 50 grams or 10 or 12 teaspoons) of this sugar alcohol sometimes cause nausea, but smaller amounts are fine.
