There's a lot of debate about artificial sweeteners. My read now is that for almost all people, stevia and artificial sweeteners are much healthier than sugar. It's very possible new evidence will emerge, in the next 7 years, that advocates for either side of this.

To be clear, "1g Stevia" here means "1g of a stevia packet" - not of the pure substance. It was mentioned in the comments that Stevia packets are heavily diluted with other things.
