Many people have been stranded in remote locations and died of starvation, despite being surrounded by various edible foods such as many seaweeds etc.
One frequently overlooked wild food that grows in abundance in so many places - is good old grass!
A major reason given for not using grass as a survival food, is because humans do not have a rumen to digest the grass properly. But there is another method of extracting the many beneficial nutrients from grass, and that is via a cold press juice extractor.
During times of strikes, pestilence, famine and even war, in most places there is an abundance of grass beneath our feet. This information may just save your life one day, because although all food supplies may disappear, grass juice can keep you going for quite some time, at least until help arrives, or you are rescued etc.
One upside of living on grass juice for extended periods of time is that you will definitely look like an overachiever of the Jenny Craig program (weight loss program)! You will also remain hydrated, which is essential to survival.
