Zach Lester, seen here working in the field of Tree and Leaf Farm, grew the kale, chef Todd Woods cooked it, and Your Health podcast host Rebecca Davis got to eat it.

It's been a year since President Obama signed health overhaul legislation into federal law. On this week's podcast we'll learn about the lingering debate over the law as it celebrated its first birthday.

We'll also get an update on the nuclear crisis in Japan, where veggies, milk and water are tainted by radiation. Blogger Scott Hensley stops by to explain how some folks are using "crowdsourcing" to map the extent of radioactive contamination.

Plus, Scott brings us an exclusive interview with the Andrew Witty, CEO of drug giant GlaxoSmithKline. He talks about how the company is working to regain the public's trust and trying to spur development of drugs for neglected diseases.

We also call up Nancy Shute to talk about sex and heart attacks.

And, finally, at the end of the program, we'll follow the route some rainbow kale took from an organic farm in Virginia to a farmers market to one chef's kitchen.
