So imagine something fragile made out of plastic - like a plastic bag - which you can easily shred up in your hands. But then you melt that bag into molten plastic, and then let it cool. After cooling, it becomes a more solid lump that's not so easily torn up.
Something similar can be done with unhealthy
starches in our foods (eg. potatoes, rice, pasta,etc) Those starches are unhealthy because they're so quickly & easily broken down by digestion into glucose, resulting in a glucose spike in the bloodstream that overloads our cellular machinery.
If we cook our starchy food and let it cool, the fragile starches can be transformed into more resistant starches that aren't so easily broken down during digestion, thus mitigating the negative effects of glucose spike.
Furthermore, if we repeatedly cook and cool that same starchy food over and over, the repeated cycles will result in more and more of this transformation.
So we want an appliance especially designed to do this cyclical cooking and cooling repeatedly for multiple cycles, in order to make our naturally starchy foods as healthy as possible.
This digital appliance will be equipped with heating element for cooking and refrigeration coil for cooling. Various pre-programmed cooking-cooling cycles will be available for various different types of starchy foods, to optimally transform their unhealthy starches into better resistant ones.
