When modern wheat is refined, most of the wheat's fiber, vitamins, and minerals are removed. Although some nutrients are added back during manufacturing so it can be called "enriched flour," it's still not a very healthy product.
I just read a fascinating book called Wheat Belly by Dr. William Davis where the author explains that modern wheat is nothing like the wheat that was grown prior to 1950. He has me convinced to eliminate wheat, even though I have no problems with eating it.
Even if you never thought about the nutritional value of wheat, you may want to try other types of pasta noodles to reduce carbohydrates and calories.
Just remember, though, noodles made of other plants will not taste like wheat, but if you experiment, you may end up liking them as well or better than wheat.
