Is Stevia Paleo? I have attempted to find an answer for this and the information I’ve found is conflicting at best.
Maelán Fontes’ Response:
There’s some scientific evidence to support the notion that Stevia is safe, even in type 2 diabetes patients.1, 2
Furthermore, it has been demonstrated to have antihypertensive properties, as shown by Chan et al.3 and a long-term study.4
Having said this, I am not aware of any study examining the potential antinutrient (lectins or saponins) content of the plant, hence we do not know the possible adverse effect of consuming this plant on a daily basis.
Hunter-gatherers used to consume a wide range of plants, thereby minimizing the amount of a single bioactive compound ingested and its toxicity.
It is known that rotating the kind of plants is a good strategy in order to decrease food allergy and intolerance.
From an evolutionary standpoint we should look at nutrition as “whole food” rather than nutrients per se.
The bottom line is that Stevia seems to be safe, but we need more research to rule out possible side effects.
I hope this is helpful,
