Way back in 1980, the U.S. Federal
government released the Dietary Guidelines for Americans, a series of
dietary recommendations for Americans aged 2 and over to prevent the risk of
chronic diseases and to assist in the maintenance of healthy body weight.
These guidelines include the following three goals:
1.) Balance calories with physical
activity to manage weight.
2.) Consume more of certain foods
and nutrients such as fruits and vegetables, whole grains, fat-free and low-fat
dairy products and seafood.
3.) Consume fewer foods with sodium,
saturated fats, trans fats, cholesterol, added sugars and refined grains.
There are different USDA food plans
that are designed to meet the requirements of households of different ages,
numbers of family members and income levels.
Economic Research Service (ERS) researchers,
the body that provides research and economic information from the United States
Department of Agriculture, undertook two studies that looked at how much
consumers were spending on healthy choices and unhealthy choices as outlined
above over the years from 1998 to 2006. Households recorded their food
and beverage purchases of over 60,000 different products into the 23 USDA food
plan categories with the beverage group consisting of all soft drinks and fruit
drinks, the processed products which include dairy products, soups, frozen or
refrigerated dinners and refined and whole grains and fresh or minimally
processed products like frozen beans and canned tomatoes.
Now for the graphic showing the
results of average at-home household spending on each of the 23 food categories (in
blue) compared to the USDA recommended level of spending (in yellow):
Of the 23 categories, you will note
that household spending on only one category came close to what the USDA
recommends; potatoes. Spending on refined grains which includes cookies,
breads, pasta and non-whole grain crackers consumed 17 percent of household
spending on food rather than the 5 percent total recommended by the USDA.
Spending on sugar and candies represented nearly 14 percent of household
spending on food rather than the fraction of a percent recommended by the USDA.
On the flip side, spending on whole fruits consumed just over 4 percent
of total household food expenditures rather than the 16 percent recommended by
the USDA and spending on legumes was less than 0.5 percent compared to the 8
percent recommended by USDA guidelines.
Just in case you thought that there
was a relationship between certain socio-economic factors and spending on less
than healthy food, according to the data, the quality of diets in American households
is not particularly related to economic standing or demographic and geographic
differences for that matter.
One of the problems is the growing
portion of fast food in American diets over the past three and a half decades
as shown here (in purple):
Fast food contribution to total
dietary caloric intake has risen from 3.1 percent in the mid-late 1970s to 13.2
percent in the years between 2005 and 2008.
What has all of this led to?
Here
is a map showing obesity rates by state in 2012:
Here is a bar graph showing how obesity rates have risen in
the United States from 1988 - 1994 to 2005 - 2008 by income level (PIR or
poverty income ratio):
Over the period, the prevalence of
obesity among men with income at or above 350 percent of the poverty level rose
from 18 percent to 32.9 percent, an increase of 83 percent. The prevalence of
obesity among women with incomes at or above 350 percent of the poverty level
rose from 18.6 percent to 29 percent. Interestingly, among low income
women with incomes less than 130 percent of the poverty level, obesity rates
rose only slightly over the time period, however, the rate rose from a
substantial 34.5 percent of women to a stunning 42 percent of women. As
well, the data shows that the obesity rate for all educational levels rose with
men with some college education having the highest obesity rates (36.2 percent)
and women with less than high school education having the highest obesity rates
(42.1 percent).
While the dietary recommendations
made by the USDA are not the complete answer to the plague of obesity affecting
American society, perhaps keeping in mind that health care costs are ever on
the rise will be motivation in itself as a prod to adopt a more healthy overall
lifestyle.
