| Gary, you raise some interesting points for discussion. I am not aware of any GI tract issues associated with eating a higher-percentage of fat. I understand that recently published long-term studies have discredited the idea the fibre is protective of the GI tract.
I would ask you to consider why you asked, "Is low-carbing a case of reducing risk with diabetes but increasing risk elsewhere?" instead of, "Is low-fat eating a case of reducing risk in one area but increasing risk elsewhere?" both are equally valid questions, and yet the default position seems to be that it is the low-carb which has to be on the defensive.
Fat is not a demon... many physiological systems including the brain rely on a careful balance of fats.
By the way, I do not believe that the traditional Japanese diet was chiefly rice and noodles.
