I like both. Potatoes are a great source of nutrients, and I find them to be very filling for the calorie cost. Wheat bread is great too, though I have been eating wheat tortillas more often recently. Bread is a great staple item, and has been with us for a long time. I do agree that there are a lot of unnecessary sugars put into store bought breads these days (sugar is the primary agent that keeps bread soft, so it can last on the shelves longer), but it is so easy to bake bread fresh at home. I like to bake small loaves so that the slices are more within my portion range, and of course I have control over what goes into the recipe.
In fact, I just ordered a "small loaf" bread machine (3x5x4 inch oval loaves) that only takes 45 min. to bake bread! I can hardly wait.
And, as far as "close to nature" is concerned: I don't find flour, sugar (or honey), yeast, water, salt, and olive/vegetable oil to be all that far from nature. Just like anything else, bread can be made in a healthful or unhealthful manner, but it is not intrinsically evil. (In my opinion.)
