Ground flax seed.
It begins to lose electrons slowly. It does not become rancid, it does not
lose food value so quickly. When I'm out and about, I grind mine, put it in
an airtight baggie, and place it in an ice sandwich.
Some immerse it in honey to keep air out, calling it linomel. Does that
prevent it from losing electrons? I don't know. I do know that it's just one
more step and unwanted extra calories. We all make choices in order to live
our lives. Rhoda
