Other than its value as a food nutrient, “nut” has come to mean a defiant, disgusting, disapproving, despairing , crazy, and insane person. Politically, “nut” usually is associated with an extremist on the right, as in “right wing conservative nut,” not those on left, as in “left wing socialist nut.”
But POVs distract from the food value of nuts. Nuts are good for you. A November 21, 2013 New England Journal of Medicine study points out in “Association of Nut Consumption with Total and Cause-Specific Mortality,” nuts can increase your life expectancy by 20% or more.
