I know Paleo does not allow legumes, and vanilla bean is obviously a bean, however, I see vanilla extract allowed in many Paleo recipes. I searched this topic and haven't found anything about vanilla extract being okay or not. I know vanilla extract is not the bean itself but it's the extract, and I'm no food scientist so what would that entail? What are the implications in terms of possibly containing lectin or antinutrients, or anything undesired chemicals?
