Example 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.
