-To think that you can simply avoid it, by not buying it, is naive.—
Actually it’s pretty easy. I buy coarse rolled oats by the pound. It contains no sugar. My fruits and vegetables contain no sugar beyond what God put in them. Likewise my animal products. And my water contains no sugar.
But you see a pattern there, don’t you. ;-)
May you live to be 100! But you are the exception to the rule. Generally, buying liquids (other than water) in containers? Good luck. Packaged foods? Look at the ingredients. And being as saavy as you indicate, I think you know I am right about this. Sweetners are everywhere, especially fructose.
