A diet of seeds will give you scurvy. A diet of sprouted seeds will give you better nutrition than you have now. Yachties, survivalists, and Mormons count on sprouts as a way to thrive on cheap stored food.
There's not much to it. Soak the seeds or beans for a day, then rinse and drain them once a day.
After the first day they've magically become fresh vegetables.
Mung beans and lentils are the easiest to find and sprout.
Eat them quick! They'll keep growing and you'll have too much.
Here's a jarfull of mung I sprouted in the cab of my truck while driving south, camping and building my going-to-Cuba canoe on the way
. Some sprouts are better grown in the dark. When exposed to light they start making green leaves. These are fine.
That's all you really need to know.
That and the fact that a lot of your food is contaminated with poison.
So you better find a source of safe water and switch to a diet of sprouts.
