Last week, researchers from Michigan State University, Oakland University, Blue Cross Blue Shield of Michigan, and the Michigan Department of Education came out with a new study showing that when schools offer healthier snacks in vending machines and a la carte lines, students’ overall diets improve. Students in schools that offered healthier snacks consumed more fruits, vegetables and whole grains, and not just at school—at home, too.

This is encouraging news for schools and school nutrition professionals as they begin implementing the Smart Snacks in School standards, which will ensure that students are offered healthier food options during the school day. Smart Snacks in School requires more whole grains, low fat dairy, fruits, vegetables and leaner protein, while still leaving plenty of room for tradition, like homemade birthday treats and bake sale fundraisers.

Schools, teachers and school nutrition professionals across the nation are working hard to make the school day healthier. According to a new study by the CDC, schools across the nation are embracing healthier policies, such as increased physical education, reducing kids’ exposure to tobacco, and of course, improving the nutrition environment at schools.   Children who participate in the National School Lunch Program and School Breakfast Program are now getting more balanced meals – with less fat, sodium and sugar, and more whole grains, fruits and vegetables, lean protein and low-fat dairy – to help them grow healthy and strong. Starting next year, snacks and a la cart options will also offer more of the foods we should encourage, and less of the foods we should avoid.

Ensuring the health and well-being of our nation’s children is a top priority for President Obama, and for all of us at USDA. We have focused in recent years on expanding access, affordability and availability of healthy foods for families and children.

Recently, we learned of some promising new results in the fight against obesity. The Centers for Disease Control and Prevention reported that the rate of obesity among young, low-income children appears to be declining. In 19 states, the obesity rate among low-income preschoolers has dropped for the first time in decades – and in many other states the obesity rate has leveled off.

Here at USDA, we’re on a mission to help all of our nation’s children have the best possible chance at a healthy life.  So, we’re very encouraged by some recent news from the Centers for Disease Control and Prevention (CDC):  the rate of obesity among low-income pre-school children appears to be declining for the first time in decades.

The declining rates show that our collective efforts are helping to gain ground on childhood obesity, particularly among some of the more vulnerable populations in our country.  Low-income children are often at a disadvantage when it comes to getting the food they need to grow up healthy, which is why USDA’s nutrition programs and resources are so vital.

When you think of steps that can be taken to improve our environment and mitigate climate change, "reducing food waste" probably doesn't come to mind right away.  But in fact, food waste is an important factor in climate change, because wasted food represents 20 percent by weight of the solid waste going to landfills. This decomposing food quickly generates methane, a greenhouse gas 21 percent more potent than carbon dioxide.

Wasted food also represents a drain on natural resources–after all, land and water are needed to produce that food.  That's why the U.S. Department of Agriculture has collaborated with the U.S. Environmental Protection Agency to launch the U.S. Food Waste Challenge, calling on producer groups and others to join in efforts to reduce food loss and waste, recover wholesome food for human consumption, and recycle discarded food to feed animals, produce compost or even generate energy.

Los Centros para el Control y Prevención de Enfermedades (CDC, por sus siglas en ingles) han publicado un reporte llamando Signos vitales (“Vital Signs”) enfocado en los riesgo de salud relacionados con el patógeno Listeria monocytogenes, causante de enfermedades a través de los alimentos.  Algunos alimentos tienden a presentar un mayor riesgo de contaminación con la Listeria monocytogenes. Así se demuestra en la evaluación de riesgos Listeria monocytogenes in Retail Delicatessens, recientemente publicada por el Servicio de Inocuidad e Inspección de Alimentos (FSIS, por sus siglas en inglés) del Departamento de Agricultura de los Estados Unidos y Nutrición Aplicada del FDA, han hecho que recientemente la Listeria moncytogenes sean el centro de atención.

The Centers for Disease Control and Prevention’s June issue of Vital Signs focuses on the health risks associated with the foodborne pathogen Listeria monocytogenes.  Certain foods are more likely to pose of higher risk of contamination with Listeria monocytogenes, as outlined in a recently published risk assessment,  Listeria monocytogenes in Retail Delicatessens, by USDA’s, Food Safety and Inspection Service and the FDA’s Center for Food Safety and Applied Nutrition.

Agriculture and food system development were featured agenda topics at the recent New Partners for Smart Growth Conference, an annual conference sponsored by the Local Government Commission, the Environmental Protection Agency, the US Department of Transportation, the Centers for Disease Control and several other public and private organizations.

I went to the Smart Growth conference on behalf of USDA Rural Development to demonstrate USDA’s commitment to investing in the future of rural communities.  Smart Growth principles can offer innovative strategies for using scarce federal dollars efficiently to promote sustainable and sound investments on main streets everywhere, and are valuable in helping rural communities consider how to creatively use existing resources and infrastructure to serve and celebrate their unique identities.

Three years ago this fall, Secretary Vilsack and I launched the Know Your Farmer, Know Your Food initiative (KYF2).  Since then, we’ve seen interest and participation in local and regional food systems grow beyond anything we expected: whether I’m meeting with buffalo ranchers from the Great Plains or with members of the U.S. Conference of Mayors, I hear about efforts to connect producers and consumers locally and interest in how USDA can help.

In meetings of the White House Rural Council, which has representatives from across the federal government, regional food systems have been a key part of discussions.

Dr. Regina Tan says three words best describe her work at USDA’s Food Safety and Inspection Service: “I save lives.” As Director of the Applied Epidemiology Division for FSIS’s Office of Public Health Science, Dr. Tan and her staff are responsible for detecting health hazards in food, like disease-causing bacteria, allergens, strange objects, or diseases humans can catch from animals.

“This job is very personal to me. I have a son who depends on me to make sure he is safe. I think of this work by putting the faces of my family to it,” Dr. Tan has said.
