“aspartame is poison”
From Wikipedia:
Aspartame is one of the most studied food additives in the human food supply. Reviews by over 100 governmental regulatory bodies found the ingredient safe for consumption at the normal acceptable daily intake (ADI) limit
... it takes approximately 21 cans of diet soda daily to consume [enough aspartame to surpass the FDA’s daily limit].
Regarding the zevia drink, which uses stevia for sweetening, Wikipedia says this:
Two 2010 review studies found no health concerns with Stevia rebaudiana or its sweetening extracts.
So we’re both good!
