Just a heads-up for those with allergies (or intolerance) to foods with corn sweeteners.
I decided to freshen up my survival food bar supply today and searched around to see what was available. I discovered that the popular ER Bars and Mainstay bars both contain corn syrup sweeteners and corn starch, both of which I am very allergic to.
The Datrex food ration bars are sweetened only with cane sugar, so I ordered some of those for that reason.
The last thing I need in a survival situation is to consume emergency rations that give me a substantial bad physical reaction that lasts for days.
