You really want to restrict any form of white bread from your diet.  If you like sandwiches, that's not an easy task.  If you like pasta in all of its forms, ditto, not an easy task.  And the reason is that white bread is so chewy,  And though it's tastelss it doesn't matter because it tends to absorb all of the delicious sauces and mustards that we put on pasta or sandwiches.  One of my favorite sandwiches is a pastrami sandwich.  Love the fatty meat.  Love the mustard.  Love the pickles.  And love how the white bread of the sandwich bun interacts with the juices of the meat and the mustard to create this exquisite toasty, spongy texture.  It is to die for.  But I hope not.  It shouldn't be this good--so good so as to die for.  Nothing should be. One of my favorite snacks was a sourdough role and lots and lots of raw butter.  It's Heaven.  And it beat hands down any kind of pastry or cake or ice cream.  I was after the fat, and the bread let was the perfect canvas for that cuisine.

Same thing with pasta.  Ooh, it's good!  Imagine it: butter, pesto, garlic, Romano or Parmasean cheese.  De-lish.  Or how about a tasty sausage, tomato with wine and mushroom sauce.  Aww. You're killin' me with these options.   And maybe that is what it is: the white bread allows us to build some deliciously home-made meals.  It is the definition of comfort food.

But at what price?  There is always a cost?  LiveStrong defines what white bread is and why it's bad:

White bread -- the ubiquitous soft and fluffy slices still favored by many -- looks delicious but has little substance. Most hamburger buns, French and Italian bread, Kaiser rolls, bagels and pizza crust are also white bread and none of them are good for you. White bread is low in essential nutrients, and may have an adverse effect on your health.

 The fact that the food has "little substance" can't be good for the different organ systems involved in processing food, like your digestive system, your liver, spleen, kidneys, etc.  So the Kaiser roll with its seeds, yeah, no, it's not going to help you.  It will make you and your organ systems tired.  Some might "Ah, once in a while won't hurt."  Maybe.  But what does once in a while look like before it becomes a once in a while lifestyle?  Also, white is low in essential nutrients.  The benefit to eating nutrient dense foods is that you tend to eat less of them. 

REFINED GRAINSA refined grain is created when a whole grain is finely ground and stripped of its bran and germ, the elements that contain fiber, vitamins and minerals. White bread is made from refined grains, which are low in magnesium, zinc, vitamin E, fiber and essential fatty acids. Even though some manufacturers add vitamins back in, natural whole grains are still a superior choice.  

Refined grains are denuded food.  But grains in general will produce inflammation.  The LiveStrong article does try to persuade you to consider whole grains, but I have my doubts.  Bread lacks fiber.  It's bulk but it's not fiber that helps you digest other foods.

HIGH GLYCEMIC INDEXThe glycemic index is a measurement of how quickly and how much a food affects your blood sugar and insulin levels compared with pure glucose. White bread has a high glycemic index because it's made from refined grains that are rapidly absorbed during digestion, causing sharp spikes in blood sugar and insulin levels. A diet that includes a lot of white bread and other high-glycemic foods -- like sweets, candy, desserts and white potatoes -- increases your risk for weight gain, type 2 diabetes and heart disease, according to the Harvard School of Public Health.
