The McDonald’s fast food emporium supplied lots of food for thought this week. In my weekly Nutrition Diva podcast, I answer a listener’s question about whether the benefits of eating fish are cancelled out if it’s a Fishwich.

From my weekly newsletter: Guess which cereal is more nutrient dense: Oatbran or oatmeal? Finally, in view of last week’s findings on the health benefits of beets and beet greens, here more delicious ways to prepare both!
