The Winston-Salem Journal's Michael Hastings points out on the Dishing it Out blog that Twinkies recently turned 80. He also shares a little tidbit of info that I found most useful: each Twinkie has only 150 calories. Why did I ever give them up?
No word on the caloric damage found in Ho-Hos, but I much liked them anyway.
Befuddled 
Those Little Debbie cream filled chocolate roll things always get me. Can’t resist. But Twinkies just 150? Wow!
Really did amaze me. The other thing he noted was that Twinkies supposedly have a shelf life of something like 28 days. My own extensive field testing (in my youth) shows that its many times that. Theres a reason we called them nuclear food.
