When I was in the hellish pre-fleet Navy they had a line configuration called 'nut to butt' in order to pack us all into as small a space as possible.
The profane line up had me declining all manner of nuts for many years.
Perhaps it was an over reaction; but I prefer to consider it a conscientious objection to that nastiness which was that phase of the military and it's coarse environment and the stupidity of those people who loved it.
Nowadays I have set aside my aversion to nuts and consume them when I encounter them without complaints.
Defining nuts as a food can be confusing. There are species of plants which bear fruits called "nuts" which aren't really nuts.
Legumes and seeds get thrown in the nut pile as a matter of convenience.
These edibles we consume are in reality a variety of things ...
But not always the "nuts" by which they are referred.
Nuts provide essential fats into the diet and can either improve health or contribute to disease depending on the quantity.
So on this National Grab Some Nuts Day feel free to snatch up the nearest set of nuts and have your way with them.
