Healthy Food at Airports?

I'm still in the middle of my work-travel stretch, so here's another travel-related post...

Do Airports ban healthy food? Seriously. I'm not the worlds healthiest eater, but I'm in the middle of being fairly successful at going to the gym at least 3 times a week. When you're like me - and you geniunely don't enjoy the act of running on the treadmill but do it anyway ... I think it gives some motivation to somewhat watch what you eat. Otherwise - kinda silly to torture yourself 3 times a week - right?

Anyway - when I travel - I find it very difficult to eat healthy - ESPECIALLY when you have a meal a day at the airport. There is nothing healthy at fast food joints or the microwave pizza places...Seriously - NOTHING.

Here's a business idea for someone... Develop a health-conscious chain for airports. Start in body conscious cities like LA, New York, Detroit(just kidding), and Fort Lauderdale. There is no question in my mind that it would work. While "the average American" probably thinks ordering a Diet Coke with their super-sized meal counter-acts the burger and fries they ordered -- I think there is a size-able market of air-travelers who would be happy to expense an over-priced healthy meal...

If not - does anyone have any good "tricks of the trade" they can share?
