So I drive a dump truck for a job and have to eat as I drive, we don't get lunch breaks. <img alt="" class="inlineimg" src="/images/smilies/sad.gif" style="border:0px solid;" title=""> I would love to bring smoothies to work, but understand that they lose nutrients and enzymes after they are blended. What would be the best possible way to do this. Isn't there devices to get the air out of a mason jar? Would this even be worth it or would I be better off just eating fruits and veggies? The biggest problem with that, it's hard to clean my hands while I work and they sometimes get dirty. I know, it's a ****ty job for eating healthy.
