CONFLICTS OF INTEREST AND THE USDA

Tuesday, June 7th, 2011

The USDA is a Department within the US government that oversees agricultural and nutrition policies and programs. Recently, the USDA released a new icon (see above) to replace the older “food pyramid.” The USDA also included several guidelines which are listed below:

Balancing Calories

  • Enjoy your food, but eat less
  • Avoid oversized portions

Foods to Increase

  • Make half your plate fruits and vegetables
  • Make at least half your grains whole grains
  • Switch to fat-free or low-fat (1%) milk

Foods to Reduce

  • Compare sodium in foods like soup, bread, and frozen meals – and choose the foods with lower numbers
  • Drink water instead of sugary drinks

In general, there is a lot of good stuff here. We like the idea of using a plate (although the size of the plate matters) to depict appropriate serving sizes as opposed to the old pyramid. The plate is easier to understand and is likely more memorable. We also like the idea of using the majority of your plate for vegetables and protein – hard to go wrong there. We certainly agree that folks should enjoy their food – some people could use to eat less, but portion size should likely vary with your activity level. Lastly, comparing sodium in prepared foods might help people avoid overly processed and preserved foods. Avoiding sugary drinks is almost always a good idea.

However, there are also some aspects of this new guidance on which we disagree. First, there is no reason that grains should make up approximately 25% of your diet and in fact grains can be eliminated from your diet entirely. If this statement made you gasp, please bear in mind that although there are essential amino acids (building blocks of proteins) and essential fatty acids (building blocks of fats and triglycerides), there is no such thing as an essential sugar (building blocks of carbs) (“essential” here means something that you have to eat because your body cannot make it). Moreover, there is evidence that grains might actually be unhealthy by interfering with the digestion and absorption of nutrients. Second, individuals who are looking to lose weight might want to restrict their fruit and dairy consumption. A diet consisting of 25%+ of fruit and dairy can add up to a heck of a lot of sugar pretty quickly. Third, and this is a big oversight, we don’t see healthy fats explicitly included anywhere. Perhaps these are implied under protein and dairy, but we feel that healthy fats and oils from beef, lamb, salmon, butter, coconut, and olives, for example, are absolutely critical for good health and for satisfying meals. Science is finally putting to rest the notion that people get fat from eating fat (as opposed to eating excess grains and sugars). As an historical aside, it is interesting to us that the 1943 version of the food pyramid called “The Basic Seven” listed fruits and vegetables as three out of the seven groups, meats and dairy as three out of the seven groups (butter had its own group!), and bread, flour, and cereals as one-seventh of a healthy diet.

So, what has happened in the intervening years to make grains so highly recommended by the USDA? Does it have to do with USDA Agencies such as the Agricultural Marketing Service; the Farm Service Agency; and the Grain Inspection, Packers and Stockyards Administration being under the same roof as the Center for Nutrition Policy and Promotion and the Food and Nutrition Service? I don’t know, but recommending so much grain consumption does not appear to be supported by the scientific evidence. Over the next few weeks, we’ll review some of that evidence in detail. In the meantime, we propose the plate below for a modified approach to eating a healthy diet.

FOODS WITH BENEFITS?

Monday, May 16th, 2011

The NYT is writing about food labeling again and how it seems that products from cereal to yogurt to juice are including claims on their packaging regarding how their product (which is usually packed with sugar) is gonna make your baby smarter or make you poop faster.

These labels tend to bother me as a consumer and as a scientist. It is misleading and unethical to lead people to believe that rice krispies will boost your immunity or that frosted mini wheats will make your kid ace an exam. Moreover, these types of claims often appear on “foods” that have been so processed and refined that I sometimes cannot even tell what they are actually made up of anymore.

As a result, I offer the labels above (which can be printed on Avery US Letter 5160 label paper – wink, wink). They read, “Humans have been on this earth for thousands of years. It is likely that early humans would not have even recognized this product as food.” I consider these labels appropriate for highly processed or refined foods making outrageous health claims. Feel free to use as you see fit.

GET STRONGER

Thursday, April 7th, 2011

Men’s Journal has a nice article titled, “Everything you know about fitness is a lie.” I’m not gonna go that far, but the article offers five “truths” that bear repeating.

1. Your gym is your enemy. Not always, but gyms can lead to boring, ineffective workouts that become loathed. Instead, get outside, play (when was the last time you played tag or climbed a tree?)

2. You need to break yourself down before you rebuild. Start at the beginning – simple movements to build strength. Squat. Deadlift (i.e., pick up heavy things). For movement, I agree with this article in that if you could only own one book on fitness it should be “Starting Strength: Basic Barbell Training” by Mark Rippetoe and Lon Kilgore.

3. Once you “get it,” you’ll love it. Variety, feeling good, and looking good are all reinforcing. ‘Nuff said.

4. Inside every man’s body is a weak muscle waiting to fail. This “truth” highlights the importance of whole body movements and exercises.

5. Being fit is about the freedom to train yourself forever. Amen. When I think about what “health” or “being healthy” means to me, I think about how I feel and I am performing (and how I want to feel and perform into old age) more than any blood test or bodily measurement. Do you wanna be the guy in the wheelchair or one of the Art De Vany or Jack Lalanne‘s of the world?
