This is the key. What causes insulin resistance? There are two main
causes--excess cortisol, and excess insulin.
Cortisol produced under stress.
Excess Insulin  produced in response to excess carbohydrate intake, of any
kind, whether tubers, grains, or sucrose.

Amadeus, do you also now acknowledge there are abundant food resources in
the tidal zones?  Or would your defenders like to defend you on this point?
