This site has some good information about where agave sits on the glycemic index as opposed to granulated and other sugars. It also has some good info on substituting agave for other sweeteners: allaboutagave.com/agave-vs-granular.php

agave is sweeter than granulated sugar (including palm sugar). Going from the reverse of the guidelines I've gotten from an agave syrup manufacturer, I'd put in 50% more palm sugar than the amount of agave that's called for. Though you'll have to adjust the liquids in the recipes, too--take out about 1/4 cup for every cup of sugar.
