Semolina is kind of a very hard wheat.

Pasta made with hard wheat takes a long time to digest and hits your blood
stream often several hours after eating.

"Fresh" pasta and pasta made with regular wheat flours digests much more
swiftly.

In any case, both kinds do eventually dump a boatload of carb into your
blood stream.  Measure your portions unless you really want an additional 80
grams in one lump.

IMO, it would seem that you're confusing whole wheat, with whole grain.  If
you're going to look for grain-made products, I would suggest looking for
whole grain rather than whole wheat.

Semolina is a type of wheat.

Sorta like this:

Semolina is to wheat, like
Pepsi is to cola.

Since 100% Pepsi is 100% cola, then 100% semolina is 100% wheat.

But semolina isn't always whole.  It's milled just like any of the
other breeds of wheat.  It can be refined or whole just like winter
wheat, duram wheat, etc.
