its upsetting to say the least to finish reading a preppers thread about putting wheat, barley,rice, etc etc away for long term storage, and then coming here and reading that it’s all bad for you...:(
On the scale of problematicals, starving to death is much less preferable than eating something that might be somewhat unhealthful.
IF (repeat, IF) this worries you, look for older, heirloom varieties; if stored properly, they can not only be eaten, but also planted.
