When I told someone recently that the new 2010 Dietary Guidelines for Americans (DGAs) were finally published this week (!) she responded with something like, "So? People are just gonna go on eating what they're gonna eat." Oh ye of little faith... Regardless of the fact that people are ultimately responsible for what they put in their mouth, and knowing full well that the DGAs are created by the same body (USDA) that regulates the food industry, these guidelines are important because they help form the basis for nutrition policy in Federal food, nutrition, education, and information programs--think school lunch & SNAP--and can create tidal waves in the food industry.
At first glance, the 2010 DGAs have not changed much from the 2005 edition, but the changes made are significant. Firstly, these guidelines were not published, as per usual, as guidance for “healthy” Americans, because they then would not be applicable to the majority of the population due to the epidemic of lifestyle related chronic disease. These guidelines were published for an unhealthy population. The document starts off by describing the state of the nation’s health, and though these statistics are well known, they are startling: almost 50% of adults over the age of 20 have type 2 diabetes or pre-diabetes, heart disease is rampant with 37% of the population having cardiovascular disease, overweight and obesity affects the majority of adults and a large minority of children, and health disparities abound. In light of these troubling facts, the new DGAs encourage people to consume fewer calories in general, less of them from junk food:
Focus on consuming nutrient-dense foods and beverages. Americans currently consume too much sodium and too many calories from solid fats, added sugars, and refined grains.2 These replace nutrient-dense foods and beverages and make it difficult for people to achieve recommended nutrient intake while controlling calorie and sodium intake. A healthy eating pattern limits intake of sodium, solid fats, added sugars, and refined grains and emphasizes nutrient-dense foods and beverages—vegetables, fruits, whole grains, fat-free or low-fat milk and milk products,3 seafood, lean meats and poultry, eggs, beans and peas, and nuts and seeds.
That's pretty solid nutrition advice.
These DGAs also address the food environment, exploring the Socio-Ecological Model of Health —there is a whole chapter dedicated to encouraging all sectors of society to work together to improve American’s food intake and activity patterns. One recommendation I enjoyed; "Develop and expand safe, effective, and sustainable agriculture and aquaculture practices to ensure availability of recommended amounts of healthy foods to all segments of the population." The elephant in the room here though seems to be the missing recommendation to stop our current subsidy system; which creates the overabundant supply of cheap SoFAS. But, the fact that the DGAs seriously consider the food environment, means we can probably expect more funds trickling down to community driven, good food programs.
There’s a lot we could go into, and I will explore more of the details, wading through particular food groups in future postings, but for now, suffice it to say that the DGAs do remain very industry friendly. One doesn’t expect to find issues such as resource depletion, food sovereignty, food justice, ecology, or traditional foodways seriouusly considered in the DGAs...but I somehow found myself hoping for it nonetheless. (When the USDA is charged with promoting the meat and dairy industries, how can we expect them to come right out and tell people to eat less CAFO beef or acknowledge the water pollution of large dairy operations or even that much of the American population is actually lactose intolerant???)
So while the DGAs do not really address questions of sustainability, if all American’s switched their diet to one patterned off these rec’s, we’d actually reduce our ecological footprint markedly from where it now stands while improving our health drastically.
