Yes, for example unrefined pure granulated sugar has about half the glycemic index of white pure granulated sugar. Lots of places around the world use it (often called jaggeree or jaggery) in all kinds of cooking and they often use it so unrefined you have to boil it and skim off the impurities before adding it to the food. It might be possible to suggest that it is not in the interest of large corporations to have it known that doing nothing with food is better for you than having them do things to it and then sell it on for a decent markup. If you were to believe that we live in societies where Governments treat corporate interest ahead of that of their general population of course.
