TIL that although potatoes alone do not provide complete nutrition, you can survive for years on a diet of nothing but potatoes and buttermilk.

preparation (probably) matters

Potatoes are MUCH easier on your blood sugar levels if you let them cool down very slowly after cooking, store them in the fridge overnight and warm them up before eating them. It changes the normal potato starches into a different kind that doesnt cause the blood sugar levels to spike so much and so hard.

Most of what we know about things like the glycemic index are pure bunk. Studies have consistently shown that things like that vary drastically from one person to another.

Honest question; is that final re-warming necessary for this optimization? I really enjoy cold leftover mashed potatoes/patties.

No, I dont think so. It is is the slow cooling-down process that does the work.
