<< It seems to me that the main plausibility about food combining is that
 our ancestors wouldn't have been likely to have had combinations of food
 at all - they would probably have gorged themselves on one kind of food
 at a time, as they found it.  Right or wrong?

Right.  And thats the whole deal about food combining: one food group at a
time, and in an order according to water content- fruit then veggies then
grains, with at least an hour inbetween.  The diet uses less energy to digest
food, thus giving u more energy out of your food.
