Ex Input:
I am on a low glycemic index diet to help control my blood sugar and hormone levels. My nutritionist recommended agave nectar as a sweetener since it's GI index is in the low 30's as opposed to honey in the low 50's and sugar in the mid-50's. I've tried supermarkets, health food stores and wholesale clubs. The prices are usually around $13 for a 32oz bottle and this is $19ish for 2x46oz. It's used like honey - substitute 2/3c for every 1c sugar and reduce liquids by 1/4th.  I also use it in a carrot cake recipe (equal substitution) instead of sugar where I substitute whole wheat flour instead of white flour and I don't decrease the other liquids. It's delicious and you'd never know that's it's actually good for you.

I have three Newfoundlands so we go through a lot of food!  One of the dogs has had severe health issues and since we've switched from commercial kibble to home made food, he's thrived!  He gets regular blood tests to monitor the drugs he's on and they have been perfect since we started on Sojos!  It will not cure his issues, but he has more energy and he can't wait for meal time!  The other two are glowing with health as well!  All three dogs coats are shiny and they have tons of energy (for a Newf!)

Original description and order said "Assorted" chocolates. What I got--weeks (!) later--was one pack of all white chocolates (the least desirable). Not worth the bother of returning even with Prime. Might be better just buying at local store (same or cheaper price) when you can see what you get.
