After some prominent Harvard scientists sniffed that the idea of an optimal ratio of omega-6 to omega-3 is “a myth with absolutely no data to support it,” I devoted an episode of the Nutrition Diva podcast to a quick review of this “non-existent” data. On the Quick and Dirty Blog, I check into rumors that foods high in choline might offer help for kids with ADD and in my weekly newsletter, I field questions about beets and blood pressure. On our monthly Smart Nutrition segment on WYPR-FM, Tom Hall and I unpack the Pink Slime controversy and on the What’s Cooking blog, I’ve got tips on foods that help protect your skin from UV damage without interfering with Vitamin D production.

Some researchers believe that environmental pollutants and industrial chemicals are to blame for the obesity epidemic. This, of course, bucks the conventional wisdom that our increasing girth is simply the result of eating too much and exercising too little. What’s the evidence to support the idea that chemicals are the true cause of our ever-expanding waistlines? Find out in this week’s Nutrition Diva podcast.

Q. After doing some research, I have been trying to reduce my intake of grains. But the big thing in the news this week is a new study finding that fiber from grains reduces the risk of colon cancer and that fiber from fruits and veggies doesn’t have the same effect. Have you looked at this new research? Do you still recommend reducing grains?
A. Just to be clear, I’m not anti-grain. Although I suspect that most Americans consume an excessive amount of grain products (especially refined grains), and I believe that grains are not essential to a healthy diet, I still think that a healthy diet can include grains (especially whole grains).
I have, however, questioned the dogma on the “benefits of whole grains” on the basis that the research doesn’t really distinguish between the benefits of adding whole grains and the benefits of reducing refined grains. (The two virtually always go hand in hand.)
Does this new study change my position? Not really. [click to continue…]
