Interesting idea. But I don't eat processed foods. And I doubt our ancestors who didn't have vitamin d deficients in the past, definitely did have processed foods.
What happens is the body seeks out from food what it needs then remaining is weed out. Except for selenium and a few others which are poisonous in higher doses.
So k2 if insuffient from diet will need supplementing.
K2 is in green veg and spring onions, kale and asparagus.
Vit D is mainly processed by the liver.
So once again if liver is being overworked to release glucose for survival then processing vit d is less a priority.
Once again the liver is failing to do one of its many functions.
IR is more related to liver than pancreas.
