Penny Kris-Etherton, Ph.D., R.D., Distinguished Professor of Nutrition (Department of Nutritional Sciences, Penn State University) about what she learned at the American Dietetic Association Food & Nutrition Conference & Expo in Chicago.
Please listen to the podcast here: [audio:http://blog.getbetterhealth.com/wp-content/uploads/2008/11/pennykrisetherton.mp3]
Penny’s take home messages:
1. Corn is not evil. The vegetable itself can be quite nutritious, though high fructose corn syrup is an empty calorie food additive.
2. There is no magic food that will melt your fat away.
3. There is no magic pill that will help you lose weight. You must decrease your calorie intake and increase your exercise.
4. Increasing protein a little bit can increase satiety.
5. Omega-3 fatty acids and iron can improve brain health.
6. Regular fatty fish consumption can reduce the risk of heart disease (2 servings/week).
7. Food first – try to get all your nutrients from the foods you consume. Consider vitamins and supplements only after you’ve been unable to get your dietary needs met from food.
8. Fish oil supplements are safe and pure. There are differences in the amount of omega-3 fatty acids that the supplements deliver, so read the label carefully.
9. A healthy diet is about eating a broad range of nutritious food (don’t scrimp on your veggies), it’s not about supplementing a poor diet with some supplements.
10. Accurate nutrition information is really important. Two trusted sources are: MyPyramid.gov and the American Heart Association

Several people have asked me if corn syrup is the root of all evil. This cheap, high calorie sweetener is adding hidden calories to everything from spaghetti sauce to condiments to peanut butter. But is it actually worse for you than “regular” cane sugar? Is there something special about corn syrup that makes it worthy of national vilification?
The truth is that corn syrup isn’t any “worse” than any other highly refined sugar – there’s nothing special about corn that makes it harmful to consume (unless maybe if you’re allergic to corn, but that’s another story). The real issue is that we humans love sweet things, and that food product manufacturers are simply adding sweetener to their products to cater to our taste buds. In so doing, hidden calories add up… and waist lines expand in response.
Folks with diabetes understand how difficult it is to find unsweetened products these days, and they have to work extra hard to avoid the high fructose corn syrup in so many foods. For those of us who don’t have diabetes (yet?) we’d probably do well to follow their example and consciously cut down on our sugar intake if not to manage our insulin levels, but at least to avoid unnecessary calorie consumption.
I myself am a bit of a sugar addict by nature – I resolved to cut down on carbs a few months ago and have dropped 10 pounds already. I have learned to like unsweetened almond milk, unsweetened organic ketchup, and I make my own sauces and avoid refined flour products.
In my next post I’ll speak with Penny M. Kris-Etherton, Ph.D., R.D., Distinguished Professor of Nutrition, Penn State University about what she learned at the recent American Dietetic Association Food & Nutrition Conference & Expo (FNCE) in Chicago. She’ll explain why all the fear mongering about corn is a bit exaggerated.

I’m grateful to the Happy Hospitalist for pointing out that color matters when it comes to food consumption. As it turns out, blue light can be an appetite suppressant. And I actually know about this first hand.
I helped to design a research study in connection with Architectural Digest and the Parsons School of Design several years ago. I was a volunteer instructor for a hospital design course in NYC, and wanted to show the students that lighting could influence eating patterns. As it happened, there was a big gala event at a local convention center, and so I worked with my friend Shashi Caan to set up three identical rooms bathed in three different colored lights (yellow, blue, and red).
We had all the gala attendees dress up in white bunny suits (you know, the kind you let patients wear in the OR) and shuttled them through the 3 rooms at regular intervals. The rooms could each hold about 40 guests and copious identical hors d’oeurves were offered.
Guess what we found? The most food was consumed in the yellow room, followed by red, and then a distant third was blue. About 33% fewer snacks were consumed in the blue room during the event (and yes we controlled the number of people in each room so they’d be equal). I found this quite fascinating, but unfortunately never published the results. You see, I didn’t receive IRB approval for any of it.
But the experiment did leave an indelible impression on my mind. As I thought about it, I realized that most fast food restaurants have yellowish interiors. From the golden arches to the lighting – companies like McDonald’s probably recognized (long before I did) that color influences purchasing and eating behavior.
Yep, I’m late to this party – and I’m not painting my kitchen yellow.

Thanks to my dear friend Dr. Rob for allowing me to “crash” at his blog during my period of homelessness. Here’s an excerpt from one of my posts:
The Law Of Conservation of Mass
Students of physics, and doctors who were not asleep during all of their pre-med classes, will recall their professor’s lecture on the “law of conservation of mass.” This law of physics states that: “matter cannot be created or destroyed, although it may be rearranged.” This is the primary reason why no one can truly lose weight. The law of conservation of mass means that even if you do lose weight, someone else has to gain it, because matter (fat) cannot be destroyed, only rearranged…
