What’s in the food we eat? Have you ever wondered if the foods past generations ate as children were more nutritious than the foods you now eat, or vice versa? Well, let’s take a look at the amount of nutrients available in foods for over 100 years!

The Nutrient Content of the U.S. Food Supply is a historical data series beginning with 1909, on the amounts of nutrients available in the food supply for consumption (not nutrients consumed), on a per capita per day basis, as well as percentage contributions of nutrients by major food groups. The series provides data for food calories and the calorie-yielding nutrients which are protein, carbohydrate, and fat (total, saturated, monounsaturated, polyunsaturated, and individual fatty acids); cholesterol; dietary fiber; 10 vitamins; and 9 minerals. Food supply nutrients are closely linked to food and nutrition policy, with prominence in areas related to nutrition monitoring, Federal dietary guidance, fortification policy, and food marketing strategies.

Clean drinking water for the world is a pretty tall order, considering that the United Nations says nearly a billion people currently go without it.  But, that’s exactly the vision that Karen Sorber had when she co-founded Micronic Technologies in 2008 as a family business.

Now a Small Business Innovation and Research (SBIR) grant from the National Institute of Food and Agriculture (NIFA) is bringing the company one step closer to making that dream a reality.  Micronic Technologies has introduced “MicroDesal,” a technology that takes well water with unsafe nitrate levels and treats it to the point where the water meets U.S. Environmental Protection Agency clean drinking water safety standards.  Nitrates are unsafe for humans – especially children and pregnant women – and livestock.

You’ve probably heard that the honey bees in this country are in trouble, with about one-third of our managed colonies dying off every winter. Later this week, we will learn how the honey bees survived this winter. With severe weather in a number of areas in the U.S. this winter, a number of us concerned about bees will be closely watching the results.

While scientists continue work to identify all the factors that have lead to honey bee losses, it is clear that there are biological and environmental stresses that have created a complex challenge that will take a complex, multi-faceted approach to solve.  Parasites, diseases, pesticides, narrow genetic diversity in honey bee colonies, and less access to diverse forage all play a role in colony declines.  To confront this diverse mix of challenges, we require a mix of solutions – the odds are that we won’t find one magic fix to help our honey bees.

As long as I can remember, I’ve had a passion for numbers and statistics. That’s why I’ve dedicated the last 39 years of my life to this amazing field.

I earned my degree in statistics in 1975 and shortly after that joined the U.S. Census Bureau, where I worked for 21 years.  At the Census Bureau, I had a really diverse experience, having worked on crime, housing, economics, and labor statistics, before ending up with the Census of Agriculture team. It was when this team transitioned to the National Agricultural Statistics Service (NASS) in 1997 that I joined my new home away from home at USDA.

During the month of April we have taken a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.

Ag research month has been an excellent opportunity to showcase all the ways in which USDA is truly the “People’s Department.”

That’s how President Lincoln described it after USDA was established in 1862. More than 150 years later, we continue to find innovative ways to improve agricultural production and create new products to benefit the American people.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.  Today we look at USDA support for a researcher striving to improve wheat through developing better disease resistance, nutritional value, and yield.

One of America’s most renowned agricultural researchers, a man who has already collected two of the USDA’s top honors, has now earned international recognition with the Wolf Prize in Agriculture.  The Wolf Foundation began awarding six prizes – agriculture, the arts, chemistry, mathematics, medicine, and physics – in 1978 to recognize outstanding scientists and artists for achievements in the interest of mankind and friendly relations among peoples.

Jorge Dubcovsky, a professor of plant sciences at the University of California–Davis and a Howard Hughes Medical Institute–Gordon and Betty Moore Foundation investigator, is sharing the Wolf Prize with Leif Andersson, from Uppsala University in Sweden.  Dubcovsky’s previous awards include USDA’s National Research Initiative Discovery Award and the USDA Secretary’s Honor Award.  Dubcovsky will receive the Wolf Prize June 1 at Knesset Israel (the Israeli Parliament) from Israeli President Shimon Peres.

So far, Irvin Arroyo has not strayed too far from the farming world. Growing up, he lived and worked with his parents at a 200-acre vineyard in Madera, California, where he tended the vines and harvested the grapes.

When Arroyo went to college at California State University, Fresno (CSU Fresno), he was given a scholarship to work at USDA’s San Joaquin Valley Agricultural Sciences Center in Fresno as an intern.  The laboratory, now in Parlier, is part of USDA’s Agricultural Research Service (ARS). The scholarship had been established by CSU Fresno and ARS soil scientist Gary Bañuelos to foster minority student interest in science careers.

“Seeing the unseen” may sound like a science fiction movie theme, but it’s actually the real-life mission of USDA scientists who use special high-powered microscopes to view microscopic organisms that play a big role in agriculture.

The facility where these scientists produce the images of the unseen world--from fungal spores to plant cells--is called the Electron and Confocal Microscopy Unit (ECMU) and it’s operated in Beltsville, Md., by USDA’s Agricultural Research Service (ARS).

Over the past several decades, satellite imagery has emerged as one of the most valuable new tools in modern agriculture. At USDA’s National Agricultural Statistics Service (NASS), we strive to remain at the forefront of this technology to continually advance our statistical products in service to U.S. agriculture. To keep abreast of how our counterparts in other countries are implementing this exciting new technology, last month we hosted representatives from the Canadian and Mexican agriculture departments in a Tripartite meeting. As geographic neighbors and statistical collaborators, we are particularly interested in each others' work and how we can learn from each other.

It was exciting to see that Statistics Canada, working with Agriculture and Agri-food Canada, is researching new remote sensing-based yield models, using vegetative indices, agro-climactic data, and survey data for 21 crops. As a result of this innovation, Stats Canada is planning to use only remote sensing to set their official estimates for these crops rather than conducting traditional surveys. This is a tremendous step forward for a statistical estimates program that we will be watching with great interest.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.  For example, researching mosquitoes that spread diseases that threaten human health worldwide.

Today is World Health Day, and this year’s theme is vector-borne diseases—those diseases spread by organisms like insects, ticks and snails.  Significant vector-borne diseases in the Americas include dengue fever, malaria, leishmaniasis, lymphatic filariasis and schistosomiasis.

One of the most egregious offenders is the mosquito, and the scientists of USDA’s Agricultural Research Service (ARS) are taking aim at this winged attacker with weapons ranging from traditional remedies to computer modeling and satellite images.
