I recently found this extensive list of popular nutritional bars that includes information about the soy ingredients used in many of them and those that are derived using a: hexane vs hexane-free process.
And there goes another convenience/snack food that I enjoyed, off my list: Cliff Bars.
I was surprised and disappointed to see that this company (likely) uses hexane derived soy in it's snack bars. :<(
I'm going to find the time to make my own nutritional/snack bars from now on. I don't want to eat foods that have even traces/residues of hexane (click to read an in-depth report about the dangers of hexane) in them. More and more, it seems that "from scratch" is the only way to insure this isn't the case.
On a more positive note, here's a post from my cooking blog with several options for easy homemade snack bar recipes you might want to try. Plenty more recipes online too.
Fast and easy to make, healthier, taste so much better and fresher. And cheaper too!
All win-wins! :<)
