The USDA National Agricultural Library’s (NAL) Food and Nutrition Information Center (FNIC) today launched its mobile application, or “app,” which calculates Dietary Reference Intakes (DRIs).  The “USDA Dietary Reference Intakes (DRI) Calculator for Healthcare Professionals” app allows users to keep track of nutrient calculations and recommendations that are based on the DRI values in a more convenient and user-friendly format. Through this new app, healthcare professionals can save time in the nutrition care process for patients and clients, while having access to credible nutrition guidance.

The National Academy of Science’s Institute of Medicine first developed the DRIs in the mid-1990s. DRIs are recommended amounts of each nutrient a healthy person should consume to prevent deficiency or harmful health effects. Initially presented in tables, this information allows healthcare professionals to use the DRIs to assess and plan diets for groups or individuals. For example, if you are a female between 19 and 50, your registered dietitian or doctor may recommend that you increase your dairy consumption to meet the 1,000mg/day calcium recommendation outlined in the DRIs. The DRIs are also used in policy-making such as setting calorie and sodium guidelines for healthy school lunches. Read more »

U.S. Farms, Large and Small

Small family farms dominate the total U.S. farm count and occupy more than half of U.S. farmland, but midsize and large-scale family farms account for the bulk of agricultural production. (ERS Family Farm Report, 2014 Edition)

Describing the structure of the U.S. farm sector is challenging, because farms vary widely in size and other characteristics.  Are they largely family businesses, or corporate operations?  U.S. farms range from very small retirement and residential holdings to businesses with sales in the millions of dollars. And descriptions based on U.S. averages hide much of the variation.

The Economic Research Service prepares periodic reports on family farms that provide detailed information for policy makers and others interested in farm policy and the farm sector.  The reports draw on data from a scientifically designed USDA survey, the Agricultural Resource Management Survey, or ARMS.  The survey, conducted annually, covers all types of farms, and is designed to accurately represent farms and farm households, including financial conditions and production practices.

It’s Quite a Pickle To Be In

Pickles of many kinds fill grocery store shelves, all of them safe for consumers thanks to the work of an ARS food safety lab in Raleigh, North Carolina.

Pickles are a popular food, but are even trendier today as more and more craft brands show up in stores and farmers’ markets all over the country. But did you know USDA’s Agricultural Research Service (ARS) has helped commercial pickle-makers, from small brands to the nation’s largest, meet the highest standards of food safety?

While pickling—storing in an acid liquid, usually vinegar—has been recognized as a food-preserver since long before the discovery of bacteria, the kind of data that today’s precise food safety standards require was not established until recently. Read more »

Spraying Smarter Strengthens Strawberry Production

Thanks to a USDA NIFA grant, strawberry growers in Florida are benefiting from a smart system that helps them time spraying to prevent diseases – saving the farmers money while minimizing the environmental impacts. The system is being adapted for growers in other states.

With the U.S. being the world’s leading producer of strawberries, the success of these tart and sweet treats is essential to the economy of a state like Florida. In fact, with a $366 million-per-year industry, the state comes second only to California as the nation’s largest strawberry producer. Naturally, strawberry growers are looking for ways to sustain their harvests and profitability.

Enter Natalia Peres, University of Florida Gulf Coast Research and Education Center professor of plant pathology.  With funding from the USDA’s National Institute of Food and Agriculture (NIFA), Peres and her research team developed an online web tool, the Strawberry Advisory System (SAS), which helps farmers spend less money on fungicides yet achieve better results with what they do spray.
