Paul,

If you go to a health store and ask for Stevia (spelling), you can buy a
little bottle of white powder of it. It seems spendy but you need far far
less of it than sugar to sweeten. For example to sweeten a large cup of
coffee, I'd say 14 oz. my wife put in six drops of the liquid form of it
and it did the job... imagine that six drops to 14 oz of  java. It won't
deteriorate teeth, mess with your insulin, mess with your immunity, mess
with adding pounds lol. Their is a very big controversy between the health
community and the government. It is used all over the world but here. It
will not be marketed as a sweetener but a dietary supplement. The
government will not endorse it as a sweetener despite it being used around
the world for centuries. The problem with it is you can't patent a herb as
you can artificial sweeteners. Another thing is it will not work  in making
of bread because yeast will not rise with it as it needs sugar. That being
said, and yeast being a bacteria, if bacteria needs sugar to multiply, and
it does, I suspect the medical and pharmaceutical field as well would not
care to see stevia used in place of sugar either. Anyway you might try it
in your Ovaltine.
