An interesting evaluation of the GRAS approach taken for these extracts is here:
https://pubmed.ncbi.nlm.nih.gov/30268795/
The article is free.
The paper ends with this comment, concerning all accepted GRAS notices for these compounds:
“With regard to safety, notifiers include data and information about the metabolism of steviol glycosides and the similarity of metabolism for all steviol glycosides in rats and humans. Estimates of dietary exposure to stevia-derived ingredients are within JECFA’s established ADI of 4 mg/kg bw/day on a steviol equivalents basis.”
That amount is roughly nine packets of purified extract a day for a 160 pound person.
Thanks for the link. Not sure I trust the FDA to look out for the best interests of the American people.
Anyone looking for an alternative to highly processed sugar should give date syrup a try. Low glycemic index, loaded with magnesium, potassium, and antioxidants.
