While appearing on CBS' Face the Nation Sunday, GOP presidential candidate Mike Huckabee was asked to answer why he lent his name for money back in February to a controversial diabetes cure considered by most in the medical community to be nothing more than snake oil. "I don't have to defend everything that I've ever done," the former governor said in response.

Long before he signed on as a sponsor of "The Diabetes Solution Kit," Huckabee, through changing his diet and activity levels, was able to lose a large amount of body weight and subsequently reverse his type 2 diabetes. He never even used the kit he was promoting -- a kit which boasts using natural cinnamon and the chemical compound chromium picolinate, along with diet and exercise, to help battle the disease.

In a February press release from the company, Huckabee stated that he had "used many of the techniques" outlined in the materials, promised that "they work," and then joined the company's founder, Joe Barton, in being "committed to health" and "spread[ing] the message."

On Sunday's program, Huckabee defended his association to host Bob Schieffer:

Well, there's going to be a lot of criticism thrown my way. One of the things that I have said is that the particular plan you're talking about is about the healthy eating, watching the kind of foods one takes in and, you know, I don't have to defend everything that I've ever done. I'm not doing those infomercials, obviously, now as a candidate for president. But if that's the worst thing somebody can say to me is that I advocated for people who have diabetes to do something to reverse it and stop the incredible pain of that, then I am going to be a heck of a good president. 

Schieffer pushed back: "Well, governor, I have diabetes, and I agree with you, and most doctors will tell you, you have to lose weight, you have to have a nutritious diet but you were also selling pills of some sort, were you not?

"No, no, there was not -- that's a misnomer," Huckabee said. "One of the elements of the plan was dietary supplements, but it's not the fundamental thing."

Feeling the heat of what backlash from this could mean for his presidential bid, Huckabee quickly changed course, offering a political spin:

[Diabetes] is one of the four big things that are costing Americans in the healthcare system, along with cancer, Alzheimer's, and heart disease. If we approach this as I have suggested, which is looking for cures rather than just treatment, we then not only save lives, we start saving serious money. And that's one of the reforms we need to be talking about nationally.
