This may not be the popular opinion, lol, but....
I tried so hard to like whole wheat pasta, but wasn't successful. I know a lot of people that do love it, but just not me, lol. I decided not to fight it and stick with regular pasta. The glycemic index isn't an issue for me. Whole grains of course contain more nutrients so they are better for you. But, I think as long as you follow a balanced diet and get whole grains from enough sources, that some refined wheat isn't going to hurt. The new USDA guidelines suggest getting at least half of your intake from whole grains, and the rest from refined grains. If you eat a lot of pasta and don't consume whole grains from other sources, then whole wheat pasta would be a better option.
