Kucinich refers to diet, younger wife

After hearing this, Armstrong interjected. "This has really deteriorated," he said to crowd applause, adding, "I would just be hungry all the time, I think."

Despite the overall serious nature of today's LIVESTRONG forum, Kucinich had several comedic moments during his turn with moderators Lance Armstrong and Chris Matthews.  After being asked if the Food and Drug Administration is always working in the best interest of the American people, the Ohio congressman lamented the amount of genetically modified food on the market -- using it is an opportunity to tout his own lifestyle choices. "This is why I happen to be a vegan, okay? I know a little bit about this." Without missing a beat, he added, smiling, "People want a president who is healthy, because if you're healthy, you can think right."

The laughs didn't stop there. Kucinich went on to explain the benefits of his diet, citing increased energy, clarity, and a better quality of life. Matthews went on to insinuate that Kucinich's new lifestyle may have helped him match up with a younger wife, to which the presidential hopeful added, "I'm 60 years old, I have a -- my wife's 29, you draw your own conclusions. Diet helps."

After hearing this, Armstrong interjected. "This has really deteriorated," he said to crowd applause, adding, "I would just be hungry all the time, I think."

While Kucinich's appearance was certainly the most heavy on the laughs, he did continue to bring it back to a serious note by telling of a woman he met in Maine who has accumulated $161,000 in debt while battling cancer. He tied this example into his call for a single-payer health-care system -- touting a bill he has written as "the only one Michael Moore says meets the requirements."
