Probably will be an over processed product. But cooked and cooled potato in any form except deep fried is very very desirable for our gut bugs. The resistant starch feeds the best bacteria we could have. In turn, this delicious food for them is used to keep a happy population in our guts giving us good digestion, good moods, and good health. So eating relatively unadulterated potato products can be quite good for us.
I absolutely LOVE raw potato. Give me a couple of freshly dug Red Pontiac or Yukon Gold potatoes and a salt shaker and I’m in heaven. Even russets, but I am not fond of the texture of their skin.
Potato starch works really well. You can get it in the health food department. 1/2 to 1 tsp. a day feeds all of the healthful gut organisms.
