Red #40, Blue #1, Yellow #6 - a rainbow of food dyes.

Artificial food dyes are everywhere. Even if you pass on the brightly colored candies, you may get a dose from baking mixes, mouthwash or canned vegetables.

On this week's podcast, April Fulton gives us the straight dope from a meeting of experts advising the Food and Drug Administration about a controversial link between food dye and hyperactivity in kids.

April and fellow host Rebecca Davis also discuss aches and pains. Experts say jogging doesn't necessarily cause knee pain, and a 100-year-old posture technique could ease back pain.

All that, plus Scott Hensley rounds up the week's blog posts â€" doctors asking kids about Facebook, the pluses and minuses of compounding pharmacies, and the Gross-Out Award goes to ... clarinet bacteria.
