Americans love, love, love their spuds:  In 2010, per capita consumption of potatoes in the U.S. hit almost 114 pounds, according to USDA’s Economic Research Service. One of our favorite ways to dish up this versatile veggie is in the form of French fries.

Of course, deep-frying those potato slices to golden crispness adds extra calories from the oil.  But what if you could indulge your French fry craving with fewer calories? And what if the technique to achieve that was more environmentally friendly than conventional fry preparation?

The last few years have seen significant improvements to the health of the school environment.  Schools across the country are increasing their efforts to prevent childhood obesity by serving healthier school meals providing more time for physical activity, and helping kids learn about proper nutrition.  It’s clear that the new, healthier school meals implemented last year are working and having a positive impact on the health of our next generation.

We recently surveyed states and schools across the country, and the vast majority of schools—80 percent—have already reported that they are meeting the updated meal standards successfully, with some states reporting 100% of schools completely transitioned to the new standards.  We expect the remaining schools to “make it official” soon, too.  In fact, a study just released by the Kids’ Safe and Healthful Foods Project found that last year 94 percent of U.S. school districts said they were on track to meet the updated nutrition standards for lunches by now.

A new academic year is here for millions of students and teachers across the country, and in spirit of the many back to school nights and open houses taking place, I’m encouraging you to explore USDA’s International Year of Statistics Virtual Open House.

The International Year of Statistics, sponsored by more than 2,000 organizations – including the USDA - is a worldwide event to help teach everyone about the powerful and far-reaching effects of statistics. When people hear the word “statistics,” they often think of sports statistics or the course they took and struggled to pass. While you can think of statistics in these terms, there is more to the relationship between you and statistics than you may imagine.

With the abundance of news and information on the food and agriculture sector, sometimes it is helpful to take a step back and look at the big picture. You might be a seasoned expert on food, agriculture, or the rural economy, or you may have just a general knowledge. In any case, there are a number of key indicators that will bring you up to speed on a range of basic questions.

How much, for example, do agriculture and related industries contribute to the U.S. economy? Which commodities are our main agricultural exports? What share of their household incomes do Americans spend on food? How do job earnings in rural areas compare with metro areas? How much of our Nation’s water does agriculture consume?

Beginning with the 2014-15 school year, “competitive foods” in schools will be subject to new nutritional standards. Competitive foods include à la carte cafeteria items like pizza, French fries, and ice cream, as well as snacks and beverages sold in vending machines or at snack bars, school stores, or other locations.

Referred to as “competitive foods” because they compete with meals served through the National School Lunch Program, these foods and beverages are currently inconsistently regulated and frequently high-calorie, low-nutrient options. Competitive foods are more common at secondary than at elementary schools. A 2005 survey revealed that 32 percent of elementary schools and more than 60 percent of secondary schools offered non-milk a la carte items. Vending machines were found in 27 percent of elementary, 87 percent of middle, and 98 percent of high schools.

The average consumer might not think about it, but for decades, USDA plant breeding research has been producing varieties that have been helping feed the world and preserve the environment. We know that you look for the plumpest, juiciest strawberries at your neighborhood market, so USDA plant breeding scientists worked to find the genes to make them taste even better.  And to help farmers in Northern climates produce more food for our tables, USDA plant breeding researchers developed corn that would mature early before the bitter cold arrived. This important work plays a significant role in our lives and USDA hopes to build on all these positive outcomes to make sure even more keep coming.  Therefore, to coordinate work on plant breeding and maximize the results from ever more limited resources, USDA formed a new Plant Breeding Working Group (PBWG) earlier this year.

In the wake of the economic downturn that began in late 2007, food insecurity in households with children remains near the highest level observed since monitoring began in 1995. In 2011, 20.6 percent of U.S. households with children were food insecure—unable at some time during the year to acquire adequate food for one or more members due to insufficient money or other resources for food.  In about half of those households, only adults experienced reduced food quality or quantity, but in 10 percent of all households with children, one or more of the children were also affected.

Food security is especially important for children because the foods they eat—or don’t eat—affect not only their current health and well-being, but also their development and future health. Studies suggest that children in food-insecure households are more likely to have negative health and development outcomes than children in otherwise similar food-secure households, such as poorer health, more frequent colds, and lower math and reading achievement.

Economists working on climate change spend a lot of time trying to predict how farmers are going to adapt.  Without knowing how farmers will react to higher average temperatures or different rainfall patterns, we cannot accurately say what climate change will mean for the future.  Farmers have many adaptation options available.  They can change the mix of crops they grow, as well as their production practices, and production might be redistributed across regions. The Economic Research Service (ERS) has looked at potential impacts including how some regions will be impacted through commodity price changes resulting from climate-driven crop acreage changes farmers make in other regions.

Each day, the Charts of Note series from the Economic Research Service (ERS) delivers an innovative, visual display of research findings. Wouldn’t it be great if these charts could be easily grabbed for use on your own website or blog? Well, now they can.

The new Federal Open Data Policy asks agencies to use machine-readable formats when they build and disseminate information. At ERS, we are already traveling down that track...for Charts of Note and more. Our goal is to improve the reach, accessibility, and utility of important research findings.

As part of USDA’s 12-month Digital Government Strategy deliverables we are sharing several new mobile and open data projects that help us deliver 21^st century service to you, our customers and stakeholders. These new tools and open data efforts will enable USDA customers, to more easily access critical programs and services anywhere, any time and on any device, in addition to stimulating further innovations:
