On tonight's ABC Evening News there was a short, low-carb friendly discussion of diet and health with emphasis on the carbs-insulin connection. There will be a webcast discussion tomorrow (Wednesday, January 9) at noon (EST).

Here's the blurb and link from ABC News's website. There's a form if you want to submit a question.

The Risks of Too Many Carbs
Live Chat: Nutrition Expert Dr. Walter Willett

For more than a decade, the public health message has been loud and clear: Eat less fat and more carbohydrates. Millions of Americans have heeded the call. But some doctors say too many Americans have gone too far in the switch to carbs. Dr. Walter Willett, chairman of the department of nutrition at the Harvard School of Public Health, says it’s not the amount of carbohydrates you eat but the type that matters. "What's become quite clear is that not all carbohydrates are the same," Willett tells ABCNEWS. In his new book, Eat, Drink and Be Healthy, Willett rebuilds the U.S. Department of Agriculture Food Pyramid, which he says is based on "shaky scientific ground," replacing it with his own dietary guidelines. You can chat live with Willett Wednesday, Jan. 9, at noon ET on ABCNEWS.com.
