Buzzfeed For Cassandra Smolcic, the trouble began at her dream internship. Handpicked to spend a summer working on movies at Pixar, the year-old logged marathon hours, and more than a few all-nighters, at her computer and tablet. At first, she managed to ignore the mysterious pinching sensations in her hands and forearms. But by the time her internship ended and a full-time job offer rolled in, she could barely move her fingers.
A related question involves how well we have complied with the recommendations targeting diet quality, which have also been highly consistent through the years.
The current version, HEI, has 12 components: Index values can range from 0 towith higher scores associated with a higher-quality diet. Researchers evaluated the diet quality of lower- and higher-income Americans, ages two and older, using dietary data from the rounds of a national survey USDA, CNPP, The average score, across all income levels, was Respondents did especially poorly on dark green and orange vegetables, whole grains, sodium, and calories from SoFAAS.
Surprisingly, total HEI scores were about the same for lower- and higher-income respondents. There were, however, differences in the ways in which low- and high-income respondents failed to meet the targets.
See the article by Palma and Jetter elsewhere in this issue for details on the differences across income groups. The DGA series has included explicit recommendations on physical activity levels since Department of Health and Human Services.
For adults, the DGA encourages a minimum of minutes per week of moderate-intensity aerobic activity or 75 minutes of high-intensity aerobic activity. For children six and older, an hour a day of physical activity is recommended.
Many Americans fail to meet these targets.
Evidence indicates that most Americans have not followed recommendations in previous editions of the DGA in terms of maintaining a healthy weight, eating a high quality diet, and getting sufficient exercise.
To answer that question, it is first important to understand the factors believed to be associated with rising rates of obesity. An "Obesogenic" Environment The DGA calls our current environment "obesogenic," meaning that it promotes over-consumption of energy and discourages physical activity.
With such striking changes in rates of obesity since the s, significant changes affecting food intake or energy expenditure must have occurred in a short span of time.
From a physiological standpoint, the cause of obesity is well understood: An individual incurs a persistent energy imbalance, consuming more energy through food and drink than is expended by physical activities. The excess energy is stored as body fat. However, the complex economic causes and consequences of obesity are yet to be understood Finkelstein et al.
No paper of this size can do much justice to the extensive range of investigations that have been made by economists, nutrition and health researchers, and other scientists concerning the factors that may be linked to rising obesity rates; however, some of the major theories and findings are briefly discussed here.
Evidence concerning changes in activity levels over time is mixed, with some studies Church et al. There is, however, very strong evidence that average daily energy intake, in the form of kcal—or "calories"—has increased substantially since the s, although estimates of the magnitude of the increase have varied from around calories per day Leonard, to over calories per day Duffey and Popkin, The increased energy intake has been attributed to changes in dietary patterns, such as an increase in consumption of high-calorie and low-nutrition snacks including sugary beverages, larger portion sizes, and more food consumed away from home Popkin, Duffey, and Gordon-Larsen, ; Duffey and Popkin, ; Zizza, Siega-Riz, and Popkin, One of the first rules of economics is that price matters.
As a percentage of income, food, especially highly caloric food, has become cheaper. But while food prices overall have declined since the s, fruit and vegetable prices have increased Christian and Rashad, The low relative cost of "energy-dense" foods has been hypothesized to be a factor in obesity Drewnowski, The difference in relative prices for different types of food may also explain some of the differences in rates of obesity found among different economic groups Drewnowski and Specter, The time-cost of food has also fallen.
For most Americans, food is now readily available and highly convenient Cutler, Glaeser, and Shapiro, The "built environment," or the human-made environment that provides the setting for our day-to-day activities, has been extensively studied in terms of dietary intake and physical activity Papas et al.Science Now ; Uncle Sam wants you to sit less and move more.

Actually, this torture rumour is really debatable. Some say that there is no such torturing in the Bush era. However, some other say that this is already a tradition in White House, even before the Bush era but the staffs are asked to keep silent about this kind of scandal and rumour.
