White rice, white bread and white pasta are 100% junk food, because as I've explained
Actually, bleaching white bread has been banned for decades. White bread is sometimes higher in the trace nutrients you mention because it is often added back in.
White bread is not a new industrial processing thing it dates back over centuries, possibly millennia to the era of Roman Empire and even the Egyptian empire. It was done to remove the various oils which make the bread go soar quickly, giving it a longer shelf life. "brown" bread without preservatives has a shelf life of only a few days before it will begin to turn rancid.
White bread and bread in general has been THE staple food of choice in developed society for most of recorded history and even before.
Whole grain, including the husk (the crunchy bits in wholemeal bread) is historically avoided because like the skin of an onion or potato the husk is designed to give pathogens something to attack and not get to the starch interior of the seed. Thus it has a high probability of carrying fungus, bacteria, viri and other nasties which are not good for bread and probably not good for you. Granted the volume and rate of production today means that grain should be cleaner.
Almost exactly the same applies to white rice.
Removing the husk, bran and germ significantly extends the shelf life of the bread/rice and while it removes nutrients and fibre, giving you effectively a blob of starch that is bread/rice's purpose in our diet, a source of carbohydrate. Always has been and should always be. Fibre and vitamins are in abundance elsewhere, so unless you eat only white bread and/or rice you will be fine.
There are also downsides to eating "brown" un-milled grain and rice as it contains substances which are not only "not good" for you, but hinder your use of the nutrients within them.
Note, starch, when cooked turns to sugars. Starch is just a complex sugar structure which aims to slow it's release. We cannot digest it on it's own which is probably partly why plants use starch and not sugar directly, to avoid us eating them. However, we have fire. You simply CANNOT call natural starch converted to sugar by cooking it "highly refined sugar", that dumb. By those measures all sugar is highly refined processed food and that's even more dumb.
I suggest you pick another fight, you won't win on the "Bread is bad for you" lunacy. That is born in the 20-something-and-beautiful-but-a-bit-thick Internet blog level of dietary advice.
EDITED for spelling and grammar.
