I didn't even want to try one when I was a kid. I felt vindicated when I saw a TV show that had two doctors on as guests. They had wrapped a Twinkie in foil and let it sit at room temperature for a year. Then they opened it and examined it and poked it. It seemed fresh, so they wrapped it up again. By the time they were on TV, it was over 20 years since they first wrapped that Twinkie and it was still soft and looked fresh.
My DH quit putting sugar in his coffee (3 tsps) when we went on the Atkins diet. Now he can't stand sugar in his tea or coffee.
I only eat whole grains (except the occasional bagel or croissant). He was surprised that he no longer enjoys the homemade white bread in restaurants.
